How to handle disconnections from wifi on an app in kiosk mode
at work we use an android device (a Famoco device updated to Android 4.4) to register the employees clock in|clock out, similarly to a time clock.

We use Famoco to help ensuring our app is always on top and to update remotely the app without relying on the Play Store.

The device is connected in wifi to our server and our app upload the clock in and clock out to the server.

Sometimes it can happen that the device lose connectivity (we still don't know if it's a bug in the device wifi chip) so we want to ensure that in those cases the app promptly retry connection to ensure the correct use).

The IT department normally does not have physical access to the device, so the app must know how to handle those cases autonomously.

Thanks

Is there a way to force android to accept slow charging?
My impression is that since the most recent Android updates my phone is shutting off the portable charger completely after warning me about slow charging. I basically get that on anything other than the charger that came with it. Do any of you find this?

I have a number of portable chargers I carry along with me that are sort of my backups until I can get to an outlet but I'm finding I can't get them to work anymore. I've checked the portables and they are fully charged. Is my assumption wrong? If not wrong is there a way to get into the advanced settings to get Android to lighten up? :)

How can I troubleshoot if I have an Android OS or hardware problem?
I have an asus zenfone 2 laser and it has gone absolutely crazy. I have done a factory reset. The problem still exists.

It basically freezes, start taking screenshots...etc.

I was wondering if there is a way to troubleshoot an Android OS for software issues (or come to the conclusion that it is the phone itself that is not okay).

Turn off accessibility service
I have rooted my phone with KingRoot app, and suddenly "Ok Google" stopped working.

After a bit of searching I've found out that some accessibility services could been blocking it. And the only one on was KingRoot one.
It is not a very useful service, so I turned it off, but in the next moment it has turned on again.

So my problem is, does anyone knows how to permanently end this service?, if not my question can be understood as, anyone knows how to have ok google working with the service?

I don't want to uninstall KingRoot, because I'm still working on the port to SuperSU, and it's not easy.

问:
Providing extra security for banking applications
Device : Moto X Play (Rooted, Android 6.0.1)

I use my mobile for everything and rarely use a PC, including banking applications, which work fine with root.

I have XPrivacy recently installed but not configured yet for all apps

Adguard installed, which maybe offers some protection of VPN ???( I don't want to use third party VPN apps, not sure if I can trust them)

Tor is painfully slow though internet speeds are good

What is a good way enhancing security for banking ? - I mostly use banking apps and at times browser when I need functionalities that apps don't offer

( I have a vague notion that creating a guest user and having only banking apps run there with XPrivacy killing all but essential permissions could help but I am not sure)

Edit: Please avoid solutions involving OS upgrade to reduce vulnerabilities, physical security of device, encryption, using string passwords, changing them regularly etc


问:
How do I determine what changes an app is making to the system?
Let me start this question with the specific use case.  I have Cerberus installed for one purpose - in order to disallow pulling down the notification bar when the phone is locked.  If my phone is stolen, I don't want the thief to be able to enable airplane mode (I use Xposed APM+ to provide a fake Power Off button on the lock screen).  But I'd like to know how Cerberus does this - what file(s) is it changing, what system changes are being made?

So my question is this - is there a tool that will let me do an OS snapshot before and after and let me compare the deltas, or monitor the actions that a particular application is doing so that I can write a simple app to do that one thing?  I've used tools on Windows in the past that do this, so I can't imagine it's that difficult - I just don't know where to look.  I have root, so root-only tools are ok.

com.android.phone has stopped working after manually upgrading Verizon LG G3 (VS985) to Marshmallow using LGUP tool
I manually upgraded my LG VS985 to marshmallow from Kitkat using the LGUP tool and the LG Stock Rom for Verizon (LG VS985 Firmware VS98547A_01_0314_ARB01.kdz).

How can I create delay before my Android phone decides that wired handset is disconnected?
I've got Sony Z1 Compact with non-rooted Android 5.1.1.

It has an issue with some of my wired headsets: any slight movement of the phone with headset connected causes the phone to stop playback despite the fact that headset remains connected. (the playback can be started again with use of headset button)

I think the reason is a slightly loose jack port on my device because my other devices don't have this problem with the same headsets.

So it seems that the only software solution (without manual toggling headset-mode) would be to create some reasonable delay at which device decides that the headset was indeed disconnected and I'm looking for the way to achieve this behavior.


问:
At what point in recovery mode should ADB be available?
I am using stock Android on a Nexus 5X, and I have a phone that is generally in a bootloader loop (unless the phone is frozen cold — weirdest bug I've ever seen).  I can now consistently get into recovery mode, and am hoping to pull some data off of it with ADB.

The catch is, I can't seem to get my computer to recognize the phone through ADB so that I can issue an adb pull command.  It's not a question of bad drivers, etc.  If I choose "Apply update from ADB", the device lists under adb devices, but I cannot issue any command except sideload which is not what I want.  (this question is different from the many "similar questions" that SE recommends as they deal with a driver issue, etc, where ADB never shows up.

I have a Nexus 5 that functions fully and likewise on it, I can't seem to figure out when I should be able to issue ADB commands other than sideload.

Is this is a question of using stock recovery?  Or is there another way to kickstart ADB that allows commands other than sideload.


问:
A question about Android recovery bootup sequence
What exactly gets copied into the /recovery partition when I execute the following command:

```<code>fastboot flash recovery <my_recovery_image>.img
</code>```

As per my understanding, the recovery image contains the kernel image and the ramdisk (initrd.img). So these should go into the /boot partition (am I right?). So, what is the content of /recovery partition after flashing the device with custom recovery when I explicitly specify recovery partition argument in the fastboot command? Or the /boot and /recovery partitions have separate versions of kernels and ramdisks, where /boot partition ramdisk would help load the operating system image from /system partition? If this is true, does that mean there are more than one init.rc scripts? (one to mount some partitions during recovery boot-up and the other for normal OS boot-up)?

Enable networking protocols over usb
This is too specific issue I encoutred with the Sony Experia XZ and somehow only this phone have this problem, The story is that I'm trying to connect a DJI Phantome 4 remote controller with this phone, but the phone doesn't even recognize that I've connected something over USB, in the beginning I thought that the  remote controller is defected, but after testing it with a bunch of other Android SF with the same version 7 all of them works perfectly with the DJI RC over USB with debugging mode active, I've posted the problem in the Sony forum and I've got this answer :

Hi @zerubeus As @nolramlb has said above, I too have had trouble
  connecting the Dji controller to the XZ. The only information
  regarding usb connectivity issues was that the XZ does not support the
  networking protocols over usb that the phantom controllers may or may
  not use. I have asked Dji which service the controller uses to connect
  but they did not reply to my query, similarly, I asked Sony mobile
  support why this may be happening and they found that usb ethernet
  services are not supported. Whether this is the service dji use, I
  don't know, and only dji can say for sure if that service is the one
  they use on Android.

Now my question is how I cant enable networking protocols, is it just a software layer or the hardware is involved here ? If it is a software restriction does a root to the device can solve that problem ?

Replicate Chromecast bootstrap behavior on Android TV Stick
Chromecast and a few other devices have the following behavior.

Upon either first start or (I want to do) when known wifi APs are not present, they host a Hotspot which can be connected to from your phone to configure it, possibly to setup the AP that it should connect to.

I would like to replicate this on an android stick I have.

Usecase: I take the android stick on holiday, and I plug it into Hotel TV, but I cant control it, necessitating me to bring along my remote.

I am hoping I can set it up so that it can, in that case, host its own wifi, so that I can connect to it and either operate it from there, or configure the hotel wifi and switch to that. I have limitless remote for controlling the stick once wifi is connected.

Tl;Dr Is there an app/way (can be root only) which I can autorun on my tv stick which checks if there is a known hotspot, and if not it hosts its own Wifi hotspot so I can connect directly to it.

I cant have it just permanently do this because I also use it regularly at home, where I do not want this behaviour.

I install Night-lies as a fresh install(clears internal storage) sometimes, and restores some apps using titanium backup (Contacts, Sms, Whatsapp).

Sometimes, I will clear cache and data of major apps like Google, Gmail, Browsers etc

Prevents data usage for rarely used apps.

问:
Estimating life span of a device model
I'm currently looking into buying an Android smartphone. Naturally, I'd like to keep using it until the hardware becomes technologically obsolete -- which, according to my prior experience with PCs (and some figures online), currently happens in something around 7 years. Just as expectedly, an official support span for a device is much, much shorter. Which in case of an always-on Internet-facing device is a showstopper because security fixes for components directly facing the network are a must here (unless I don't care about hackers stealing my online/banking credentials and/or making the device a bot in a botnet).

So, I'm interested in figuring out a way to determine a device's potential life span more productively than googling each model (which proved ineffective). Below is the information I have. Could you check my estimates and fill in the missing bits?

Hardware:

reliability/physical wear: unknown. Assumed flagship products to survive for at least 5 years but see some others' devices (like Sony Xperia Z3) already start breaking after 2 years.

Not planning to subject the device to hostile environments except occasionally getting into rain.

repairability: estimated by http://ifixit.org

the main distinction is how much it can be taken apart, i.e. how much will need to be replaced when any one part breaks

spares: taking "while supplies last" into account, my estimate is ~5 years for major models and 0-2 years for obscure ones

warranty: 1 year, didn't see anything longer

Software:

A new major version1 of Android is currently published once a year

Blobs

assume published/bundled blobs to be compatible with at most one major version.

Google supports two years' worth of new versions for its brands + 1 more year of security fixes

other manufacturers: unknown, assumed 1-2 years

With Google having standardized the 3D API in 7.1, proprietary video libraries should stop being an issue

Manufacturer-customized firmware

blobs are likely to be binary incompatible with anything but stock firmware, so this automatically writes a device off as soon as the manufacturer ends support (?)

OSS firmware

Open drivers

Unknown. Some manufacturers are/have been rumored to provide these but the information I found is fragmental and contradictory

Reversed drivers

I've found evidence of a number of efforts but too, fragmental and contradictory

The likeliness of a successful effort is proportional to the 1)combined popularity of models with the hardware and 2)availability of specs for it. The number of the building blocks should be at least two orders of magnitude less than the number of models, so it should be possible to gets some stats. Anyone gathering such statistics out there?

3rd-party firmware

Strives to support devices for as long as practical.

Has to use bundled/published blobs, so the support is limited to as long as the blobs are usable (don't know whether Cyanogenmod resorts to compatibility layers for them). Those who don't use blobs lose major parts of functionality (e.g. Replicator doesn't support 3D graphics and Wi-fi).

By necessity, only support high-profile models

Roadblocks for firmware burning

all over the place, even the same manufacturer doesn't stay consistent. Any database?

I do see that overall, the Nexus line enjoys the best software support but I don't like its ditching of external storage (and didn't buy the excuses), so I'm evaluating other options.

1looks like the code name rather than numbers define which versions belong to the same "major version"

Can I tether Internet from one android device to another android device using USB?
I have a Jide Remix Mini and it is a pain in the neck when it comes to Wifi. It seems as if it steals the I.P. Address of another device on the router, sucks up all the bandwidth, and then still can't get fast speeds. Of course, all the other devices on the router start having issues as well.

I also have an android phone, and I LOVE IT. I have tethered my computer to it to give it Wifi when the wifi card quit, and it's done a fine job.

So now I had an idea. Would it be possible to tether my phone (android) to my Remix Mini (also android)? I want to give the Remix mini Internet WITHOUT connecting it directly to the router via it's Wifi card. I tried doing it via Bluetooth, but I only got speeds of .2 megabits/second (our router sends about 12 megabits/second). So I tried plugging in my phone to the Remix's USB port and then in settings checked "USB Tethering". The Remix seems to not recognize the device as a source of Internet.

Is there something I'm missing? How can I fix this problem, or can it be fixed at all? I have other devices that I am willing to use listed below. Thanks!

iPad Mini 2, iOS 9.3, Jailbroken

Mobile data times out on Sony Xperia X5 Compact
I have a Sony Xperia X5 Compact (Android 6.0.1) which suddenly about two weeks ago lost the ability to transmit data over the mobile network. All connections just time out. The behaviour is the same in all the apps i have tried so far.

There are no issues with calling

There are no issues with WIFI

The balance on the prepaid card is 1gb.

Unfortunatly I have a cheap prepaid phone operator that gives extremely limited customer service and have just bought a six month charge.

I'm coming to whits ends, this is what I have tried so far:

reset the network settings

changing to a new sim card (which works fine in another phone)

What is the difference between versions like 20H or 20A for LG G3?
LG G3 phones are named differently like: F400 is Korean, D855 is international, D850 is for USA AT&T, D851 is for USA T-Mobile etc.

However, ROMs for G3 are named like this: [LG][G3][D855][20V]

App asks for Google account password (WhenHub) - how can I verify authenticity?
WhenHub is not the second app I've seen this happen, and it seriously rubs me the wrong way. When you start the app it given you a series of options to sign in (Google, Twitter, LinkedIn).

When choosing any option, the app prompts the user to enter the username and password inside the app. This presumably sends the user to the given provider site. However, having some background on building apps I can easily see how I could create a look-alike of the Google sign-in page to hijack the users data.

This is serious enough for me that I'm never going to be able to use this kind of app. Am I paranoid? Given the lack of a URL, is there any other way to verify that this page is indeed provided by Google and not being spoofed?

LG G3 Verizon, No Boot
Last night I was using my Verizon G3, fully updated, not rooted, and it shut off and won't come back on.  If I remove the battery it will begin to boot then go to black screen before it gets to the "Verizon" screen.  The battery had about 40% charge left when it went off.

I can get to the system recovery screen.  Plugging it in prevents it from even beginning to boot and if I plug it in when it's on the system recovery screen it stops working then goes to black screen after a few seconds.  I've selected clear cache, factory reset and safe mode, none of which works.  Every time it begins to do something then goes to black.

The phone is almost 2 years old, I know I should upgrade but I'd really like this phone to work a bit longer before I get a new phone.  I've not had any issues with the phone recently other than the occasional slow-down that restarting would remedy.

The only recent app install was one I installed earlier that day from the play store called "Spread Sign" which is a sign language dictionary that was recommended to me and is very highly rated and seems completely legit. I've not heard of it causing issues with other or on my LG tablet and it had been working fine for hours before it shut down.

How does Factory Reset Protection Lock work?
I'm trying to bypass the Factory Reset Protection Lock on one of my phones running Android 6.0, but all of the tricks found on the net simply don't work. I basically tried two of them: Factory Reset from the Settings menu (this doesn't remove the lock) and unlocking the bootloader, which also doesn't work because I can't simply get the developer's options by pressing the compilation number several times. So I don't think I will remove the lock, but I'm just wondering how this security feature works.

Basically when you do a Factory Reset, you simply format /data/ and /cache/ partitions. So no user data is available on the phone after the process is done. So what's the difference between doing Factory Reset via Settings and via recovery mode? What other partitions are involved and what Android does to them in order to maintain the lock? If I formatted that partition (or partitions), would that remove the lock?

How do I set the timer tone on a Galaxy J7?

问:
How to fix DNS_PROBE_FINISHED_NO_INTERNET on an Android tablet?
What I notice:

I can't connect on my tablet to the Internet in applications (Android Chrome, Youtube app, Facebook, etc.) My tablet says it is connected to the Wireless router. The router seems to be OK, my phone can connect to and get access to the Internet, my tablet fails to go online, Chrome reports DNS_PROBE_FINISHED_NO_INTERNET, other apps say that my device is offline.

I have set up a webserver on my computer connected to the same network and my tablet can connect to it via the IP address and port number of the http server, which makes me conclude that my tablet has some DNS related problem.

If I try to access some website via its IP address e.g. 23.21.146.13 (wdl.org, World Digital Library) the Chrome browser reports ERR_ADDRESS_UNREACHABLE.

Steps I have already taken:

Restarted the tablet

Shutdown for longer than 10mins as a recommended way for flushing DNS

Chrome Cache cleared

Removed the Wifi-Network from the list of Wireless networks and reconnected

Tried connecting to the router with a manually set static IP, made no difference (but with DHCP the tablet was not showing an IP)

rebooted router

Some device info:

```<code>Model: Asus ME173X
Android version: 4.2.2
Kernel version: 3.4.5
Chrome version: 55.0.2883.91
</code>```

My desktop computer and my smartphone have no problem connecting the Internet via the same router.


问:
How can I display as many Unicode blocks as possible in Android?
I study linguistics and ancient scripts, and this requires glyphs on high Unicode blocks which most fonts do not support. Unfortunately it seems like most apps in Android will only render the glyphs of whatever primary font is substituted for Roboto-Regular. This is very unsatisfactory because there are no font solutions which even come close to supporting all of Unicode. A mix of several fonts is necessary.

Luckily I do have a godsend in the form of Firefox. I'm not sure if it's due to the fact that they switched rendering engines recently, or if it has always done this, but Firefox will render characters using any font in the system font folder. Meaning even if your primary font doesn't have the glyph, it will still display so long as you have a compatible font somewhere in /system/fonts.

It would be fantastic if the Android system as a whole would do this, but sadly Firefox is the only app I know of that does. None of the other Web browsers work this way including Chrome. If anybody has any suggestions on how to increase font support in other apps like Wikipedia I would appreciate it.

How to create a VPN over Tor connection on android?
I am trying to setup a VPN over TOR connection on my phone so that the connection looks like this: -

My device -> Tor -> VPN -> Internet

I use orbot , OpenVPN connect app and also orwall. I ran orbot and configured openVPN to use Tor proxy (localhost: 9050). But the vpn wont connect.

But when i looked up it says that this method works in windows which handles sockets in a peculiar way. In other OS, one has to deal with some 'infinite routing loop' problem. ( comunication between tor and  tor entry relay would fall back into the vpn) Eddie for linux and OS X solves this problem by talking to the Tor Control to detect and route correctly the guard IP addresses.

How do i bypass this infinite routing loop problem?
Is there any way to exclude orbot from using the VPN connection ? Or is 'VPN over Tor' impossible on Android?

问:
Intercept (bluetooth) audio to add preamble sound
Is it possible to intercept the audio going to bluetooth?

When using a bluetooth headset for either navigation or exercise (endomondo), if the bluetooth is not getting any audio, it hibernates, taking a second or two to wake up.

So the prompt I hear could be "meters turn left" (with the value missing), because the first part is cut off.

It is not any audio files which could be edited; it is synthesized speech, and the problem exists for many apps.

So is it possible to make a "driver" which intercepts the audio, and sends a "Gong" chime or something to wake up the bluetooth before sending the speech audio?

I could probably make a low volume or sub/supersonic audio file to play to "keep the channel open" if I don't want to listen to music, but I'm afraid it will drain the battery.


问:
A way to play Viber Push To Talk Files with Sentimental Value
I have a folder with a bunch of Viber (the communication app) Push To Talk audio files, in a PTT folder.

They are from conversations between myself and my partner, who passed away a year ago. They were on a phone (Moto G 2nd Gen) that had a dead battery that I couldn't fix but somehow managed to resurrect itself last night after I charged it nonstop for 4 weeks. I was overjoyed and found my conversation with her in tact. However after browsing it a bit, as soon as I connected my old phone to the internet (I was planning to backup the conversation to my google drive), it seemed to overwrite my conversation with her, possibly as I have Viber installed on my newer phone (Moto G 3rd Gen) that I have been using for the last year. I now only get the 'Welcome to Viber' message when I open the app. Surely the entire conversation wasn't deleted in that split second? I see that viber has 404mb taking up the misc folder but I think that is mostly images (which I have saved)/ It could be in the cache but not sure how to access that.

So anyway, I find myself trying to salavage both the text messages and the audio files. I can't find the text messages so I fear they were immediately deleted when my phone synced. However I salvaged the PTT folder and I need to try and find a way to play these files outside of Viber, or convert them. Anything! There are over a thousand of these files of our voices. I need to hear her voice again.

I mailed Viber support but no luck there so far (though I'm still waiting for their latest reply).

It's so frustrating to have this surface after a year and then lose it again in the same evening.

Any help appreciated (and that is an understatement) with how to play or convert these push to talk files or locate the text messages.

Not receiving MMS messages from iPhones?
Whenever someone with an iPhone sends me a text, I can't see it, and instead get a "Download" link...which always fails to download anything. Googling shows this is likely due to a non-standard feature iPhones implement, where if you send a text to multiple people, it sends an MMS message instead of an SMS message, and it seems the default text messaging app in Android doesn't support MMS messages.

Is there any way I can fix this on my end? Is there a setting I can change in Android to read MMS messages, or a different messaging app that support these?


问:
Playing all sound from one device to another
Let me explain my situation first. I have a tablet that is connected to a Bluetooth device that is connected to my auxiliary of my car speakers. I can only connect one device at a time. I have a tablet in the back of my car that my customers, as an Uber driver, can use to listen to their own preferred music or media. It's too complicated to switch back and forth each time I pick up a passenger.

I tried solving this by getting a auxiliary spliter. So when the customer in the back starts playing their music, all I have to do is turn my music off and we can hear their music or media. Otherwise both of our music plays simultaneously.

I could deal with that but there is a static interference from using the splitter, which I can't seem to eliminate, unless I manually disconnect the splitter. Interference seems to come from having two devices connect to one line, even if one device is not having any sound output. I can disconnect any one of the two devices and the static interference goes away, so it's not the splitter itself in question.

So without installing some manual switch to switch back and forth to keep from having a cross connection interference, I'm trying to find an app that works kind of like Spotify new connection does. Where I can play audio from my back tablet and it plays through my front tablet.

After a bit of research, I come across a lot of apps that come close but not exactly how I need it to. I need to make it convenient for the customer because they tend to shy away from making me feel uncomfortable in my vehicle.

Preferably I would like my back tablet to take over the sound of my front tablet. So even if I'm playing music on my front tablet and someone starts the tablet in the back it will turn my sound off and start playing through my tablet in the front which has a constant connection to my Bluetooth.

Anybody know a way that I can accomplish this even if not the way I intended originally. If not a app maybe a specific Bluetooth device that will allow one device precedence over another without having to manually switch back and forth. Or maybe something that I haven't even thought of.

By the way I have SureLock installed on the tablet in the back. So whatever suggestions you might come up with it has to be able to run through that.

Thank you for your help and I appreciate any suggestions you might offer.

Any way to make Text to Speech not mute the background audio, but just turn it down?
I'm coming back to Android from iOS, having been a heretic for a few years.  I'm using a Nexus 6P.

The most jarring bit of the transition has been my phone's muting of music being played over bluetooth for text to speech.  I use Waze for driving, and listen to either music or podcasts during the drive.  Waze is a rather chatty program, but on iOS it was only slightly annoying.  iOS reduces the volume of whatever you're listening to when speaking;  my 'Droid is just flat out muting everything else to speak.

I find my Nexus' system to be really disorienting, especially during podcasts.  Suddenly, the voice I'm listening to changes, it's at a much louder volume than whatever the mixer on the podcast was set at, it shouts some street names at me, and then I get back to the podcast, and I've lost where the speaker was at in their point.  While I couldn't understand the podcast under the directions on iOS, I at least didn't get disoriented, because I could hear that the conversation was still "flowing" behind the directions.

Android's incredibly flexible, so I'm holding out hope that there's a setting or software I can install to do this.

Acceptable Signal Strength Ranges for 2G/3G and 4G

问:
Smartphone not booting up even after firmware reset, but after sales service says “defect not found”
My Sony Xperia M5 is not booting up. The screen is off, no LEDs are lit, it doesn't react to any buttons. It already happened several times. I wasn't doing anything specific, just was using it normally, and then suddenly it would hang up. This last time it happened while it was charging.

After about 9 months of usage, it went into a boot loop, which I was able to resolve by switching it off/on (with a hidden power button). It took several attempts, though.

About 2 or 3 weeks later, it went into a boot loop again. This time switching it off didn't help, so I tried resetting the firmware using the official tool from Sony. It didn't help either, so I brought it to the after sales service. They updated the firmware, and it was enough to fix it. They wrote that "the defect was not found" in their report.

After 2 or 3 weeks, the phone stopped working at all: the screen is off, not responding to any buttons, including hidden power button and combos like power+volume up/down. Again, brought it to the service, with the same result: resetting firmware helped, but "the defect was not found". This time they did some "WRT test" (no one has any idea what it is exactly), which was fine too.

Now, again, after 2 or 3 weeks, same happened - not working at all.

Phone condition is fine and I used it properly:

It hasn't fallen once, didn't contact any water, was not affected by extreme temperatures, (electro-)magnetic fields, radiation, etc.

Viruses are pretty much excluded: it had an antivirus installed, I only used apps from Google Play, and only the ones I trusted. I don't use any Wi-Fi spots outside of my home and office.

The battery is fine.

Now, I just want my money back, but the only two documents I have on hand say that the device is perfectly fine, so the shop will refuse it. I want something to prove the defect is actually there. My questions are:

What kind of problem can it be? If it's a hardware problem, why would firmware reset fix it? If it's a software problem, why would it even occur? My only idea is that it's a memory failure, but there was no indication of that when I did the firmware reset (I assume it should do at least basic tests).

Is there a way to perform any conclusive tests by myself? I talked to managers in the service center, and they pretty much don't care. I have to chance to talk to engineers directly. I won't open the case or anything like that, and also now it's doesn't load at all, so the only options is to use some software on PC, with a USB cable. Is there any software for that?

Onboard ethernet drivers for Android-x86?
I have recently installed Android-x86 6.0 RC1 on a USB Flash drive, so I can test compatibility in various PCs and notebooks. One thing I noticed is that the Ethernet card is never detected (probably no driver) and the only option is to use the Wi-Fi card (for notebooks) or a Wi-Fi USB dongle (for PCs). This is not very convenient, at least for PCs. Is there any way to make the build-in Ethernet card work? I know there is a USB Ethernet adapter that works in Android, but this is pointless. If I have to use a USB adapter, I would use a USB Wi-Fi dongle. The point is to use the build-in Ethernet so I won't need to add anything extra to the PC. Is there any driver for the most common LAN cards such as Realtek RTL8111F and its variants found on many modern motherboards? How do I install it? Any app that can enable Ethernet?

Thank you in advance

UPDATE: No drivers needed, LAN works out of the box. I didn't realize it because I expected to see something relevant to Ethernet in Settings and was nothing there. When connecting the LAN cable it shows a <-> icon top right at the bar. As long as you see that you are online, that's it. Actually I am not sending this update from an old notebook that the WiFi is not detected by Android but the LAN works! Thank you all!

I encrypted my Moto G4 Play using an alphanumeric password as the lock screen code because i thought that would increase the encryption key strength. After this, i changed it to a numeric lock code for convenience. Everything worked well until i power it off. Now it says the password used is correct, but the data is damaged and i must factory reset it. As far as i know, android encryption is implemented using luks and cryptfs, so i might be able to download dthe partition and decrypt it. Unfortunately, I also deactivated ADB and unrooted the phone, so i just erased everything. Is this a bug, or i did break the keys when i changed my password protection?</p>


问:
Properly migrate to larger SD card on Android 6.0?
I've got a Samsung S5 (T-Mobile SM-G900T)that's rooted on Android 6.0.1 and I want to upgrade my 64GB card to a 128GB one.

There are a few reasons I don't think a simple copy and paste will work:

The SD card itself has a unique name now (6CAB-391A). Any new SD card I put in will have a different name.

I've used the built-in feature of moving apps to external storage in Android. I have quite a few apps that have been moved off of "Internal Storage" and into "UsbStorage" using Application Manager > [app name] > Storage.

My SD card has not been adopted as internal storage. It's still labeled as an "external SD card" and has not been encrypted. There is also no option to migrate.

I suspect that a simple copy and paste will break a LOT of links and my apps will no longer work.

So what's the proper procedure on Android Marshmallow to migrate to a larger card?

问:
Why does Thunar suddenly see SD card as empty?
For several days, I have been able to access the SD card of my phone from Thunar having installed libmtp via MTP. Now, when I go to Thunar to mount my phone, it does not show the files inside the SD card.

Thunar correctly reports that the SD card has several GB of used and free space, so it knows there are files on the SD card.

Thunar shows no files on the SD card.

If I connect with adb, I can browse to the SD card and see the data is still there.

I can use Thunar to still browse the internal storage of the phone.

I am not aware of changing any settings to have caused this to occur.

The phone and SD card are brand new.

What might have caused this change in behavior?

Developer options only show USB debugging on QMobile devices
I have QMobile with Android 5.1 (rooted). I have enabled Developers option by tapping 7 times the option which enables it, and there are supposed to be a few options in the Developer options. However, there is only a single USB debugging setting.

I want to enable mock locations. The settings which are supposed to be there can be searched but cannot be enabled.

I have tried all the solutions: factory reset, upgraded the OS, tweaked, but nothing worked.

问:
Can I get Apex Launcher's scrolling background to work on EMUI 4.1?
I got my new Honor 8 this past Monday, and after extensive tweaking (including hair pulling and uttering of words not approriate in respectable company), I got it to work and look the way I want it to, except for one thing. The scrolling background of Apex Launcher simply refuses to work. I've browsed through the system settings and the Apex settings until I've gone blind. I've tried to change the background setting of Apex to non-scrolling, restarting, changing it back to scrolling and restarting again, but I simply can't find a way to get this working. Is there a way?

I'm using Wallpaper Changer as live background, but I've tried disabling it, and instead using EMUI's native function to randomly change the background image, but this makes no difference. I've also tried setting Wallpaper Changer to use static background rather than live background. This also makes no difference. The image is cropped to the physical screen resolution (1080x1920) and the leftmost part of it shown on all screens.

For example, this image

is shown like this, regardless of which screen I'm on

I've rooted, and because of issues with TWRP and SuperSU on EMUI 5.0, I won't upgrade until those are resolved.

I'm not in any way affilated with with any software mentioned above, I'm simply a user. The images above have been created by myself, and you are free to download and use them as you see fit.

UPDATE: This suddenly started working. I don't know what fixed it, so I don't think this can be classified as an answer. It started working after I shut down to replace the SIM, because the transfer of my number from my old carrier to my new one had just been done. After booting up again, the scrolling background was working. As far as I can remember, I had changed no settings since I last rebooted. I did receive an update to Wallpaper Changer, but that came after the scrolling background had already started working, and the changelog only mentions adding the ability to darken the wallpaper. A mystery, but I'll leave it at that, unless someone has any ideas about what has happened here.


问:
Will there be a performance issue if I put many files in a single ext4 directory?
I have a database of 250,000 tiny audio files that will grow to perhaps 500,000. I need to copy this to my Android phone's ext4-formatted internal storage.

I have discovered that some computers are unable to support such a large number of files in a single directory.

Will an Android 5.1 phone prevent me from moving 500,000 files to a single directory? If it permits this number of files, will it experience a slowdown in reading the files if they are all placed in one directory as opposed to distributing them numbered directories?


问:
Is it possible to disable admin rights of a malware?
There is a smartphone with anroid 5.1. Another user installed an app from a non-verified source (some hacks for Clash of Clans afaik). To uninstall it I have to drop its administrator rights in Settings -> Security -> Device administrators. The problem is that when I click to uncheck it, device locks and I hear two check sounds (check and uncheck, I suppose).

When I go to settings again the checkbox is still checked. The same behaviour when using safe mode.

How to remove malware-originated administrators?

How to disable captive portal login detection on Android M
I would like to know if it possible to disable the captive portal detection required by my WIFI HotsPot of my company. I found this question, the solution of which should remove the WIFI notification for enter the login / password of the captive portal. May be I didn't understand well the problem due my poor English skill. I don't want to transform my Android Box to a new WIFI HotSpot Box. Rather, I want to connect my Android system to the WIFI captive portal of my company. However I applied the booth solution of the question  above. No issue as all the ping to outside are lost, and the system still isolated from the network. Everything it's working with an authentication.
When I'm connecting to the HotSpot of my company, the status is : Connected, No Internet.

As the Android Box has been declared to pass through without any authentication on my WIFI network, my system should not ask for any login and password, the MAC address should be the identification only

Thanks for any help


问:
Bluetooth Headphone & Phone BT Media Volume Controls Now Separate
I have a pair of Bluetooth earbuds and a pair of Bluetooth headphones I use with my Nexus 6P running Android Nougat (7.1.1).

Two weeks into using the earbuds with my phone back when I first got them, the audio volumes separated: during the first two weeks of use, changing the volume with the buttons on the earbuds would directly change the volume of my phone and there was only one volume control (directly changed by both phone and earbuds). Unexplainably, while I was listening one day, the audio volumes separated: my phone's bluetooth audio volume has a range and the earbuds have their own (the buttons on the earbuds now control an imaginary volume slider that changes their volume but not the volume on my phone). Then the same thing happened two weeks into using my headphones: the buttons on the headphones used to control my phone's BT audio slider, but now change the volume without changing the BT audio slider (each has to be at 100% to get maximum sound now).

How can I stop the audio volumes from being separated between my BT earbuds/headphones and my Nexus 6P and why would they have separated in the first place? Basically, how can I make the volume controls on my Bluetooth devices control my phone's BT volume again?

问:
OTG USB drive showing as file instead of folder
So I have run into a problem with my Nexus 7 2013(2nd gen).
Some apps have not been able to find my OTG storage (Such as Spotify) that is attached to my device, but it is been able to find it on my Nexus 7 2012(1st gen) and OnePlus 3. I have narrowed down the problem to this:

http://imgur.com/a/qVvje

In those images you can see that the OnePlus 3 and the Nexus 7 2012(1st gen) have the OTG storage device showing up under "/Storage/usbdisk" and "/Storage/18FA-B433" folders where as the nexus 7 2013(2nd gen) shows up as "/Storage/0193-1CFF". But the problem there is that the first 2 show up as folders where the nexus 7 2013(2nd gen) only shows up as a file in 3rd party file explorers.(I can still browse the files in the built in file explorer in Android)

Does anyone here know what the problem could be causing it to show as a file instead of a folder and how I fix it?

问:
LG G4 Problem with "camera unfortunately stopped working"
Recently my camera on my LG G4 has been having some issues and is not working at all.

When opening the camera app either front or rear there is just a black screen and after a moment the message "camera unfortunately stopped working" and the app is closed. Also I have checked that the flashlight is not working but that must be related to the camera problem I guess.

It is not the first time it happens. Sometime ago I had the same problem for about two weeks but the problem magically solved itself. But know it reappeared when I tried to open the camera through the locked screen menu while having another camera app which might be unrelated but I am not an expert.

I have tried several usual methods to solve the problem:

Rebooted the phone;

Deleted Cache (Both camera app and gallery);

Deleted App Data;

Tried a third party app;

Factory Reset;

Nothing Worked!

I have know tried to use adb and android studio to see what kind of errors are issued and what I got was this:

Eject SD card via ADB
Is it possible to emulate physical eject/cut power supply for SD card in Android via ADB terminal?

What I'm looking for is something similar to the functionality achieved on GNU/Linux for USB devices via /sys/bus/* files.
However, if there is other "Pure Android" way, it will also suffice as long as it works.

The important point is that SD card should not be properly unmounted, but rather appear to the system as a sudden eject.

How to register new extensions as text files (.Rmd)
I have R markdown (.Rmd extension file, uses Markdown syntax) file on my Dropbox. Regardless of trying to open it directly from Dropbox application or exporting it to my Android device, I see information that I have no application to open this file.

There was question about many extensions:
How do I open a text file of any extension in Android?

but suggested answer does not work for me - I have DroidEdit, but my Android phone still claims that it is unable to open .Rmd file.
Obviously I can change an extension from .Rmd to .txt, but this is rather not efficient way of seeing files.

Is there any possibility to say Android 6, please treat .Rmd as text files / register new files extensions?

Please note that Dropbox app does not show me open file possibility as suggested in following thread:

Linux Mint 18 freezes after a while with connected Android Nexus 5X
I am developing Android apps using Android Studio 2.2.3 with my Linux Mint Cinnamon 18 laptop.  After a while of having my Nexus phone connected to my computer the laptop will hang and I can't click on anything or initiate any action (on laptop).  Simply unplugging my Nexus fixes the issue but I would like to know the cause and solution so I can just keep the Nexus phone connected when I am using it as a development test device.

Under Developer Options on the Nexus running 7.1.1 I have "Stay awake" checked.  USB debugging is checked. USB configuration MTB.

Disable Google cast
I'm having a problem where my phone will ask me to connect to a non-existent chromecast when watching something on YouTube or Netflix. It'll show a popup asking me to enter a pin and when I close that menu it just opens another right away. It seems to be triggered by hitting the volume buttons.

My phone is an S7 edge and I'm running Android 6.0.1. I don't have a chromecast connected to my internet so it shouldn't be automatically trying to connect to one. I've cleaned my phone's screen and removed the case, but it's still happening.

How can I fix this problem, or just disable connecting to chromecasts entirely?

This appears to be caused by Netflix. I didn't use it for about a week and no chromecast popup appeared in any app. I opened it recently and then it started happening again.

Google Maps navigation popping up eratically
Whenever I'm using Google Maps to navigate to a destination, Maps keeps popping up. It doesn't matter which app I'm in, Maps comes up on the screen and ALWAYS restarts (!) navigating to the last destination I specified.

Sometime it even pops up on itself, asking "do you want to stop the current navigation"

This happened about 2 weeks ago. I used to be on the beta channel for maps, but I quit that. Same with the current stable. I already tried removing the app and clear all app data, to no avail.


问:
Switch between soft keyboards easily while using bluetooth keyboard
In Android 6, there is a close relationship between software and hardware keyboards. The features and behaviors available from a hardware keyboard depend on which software keyboard is in effect.

For that reason, it is sometimes desirable to switch between different soft keyboards while using a hardware keyboard. However, the obvious way is awkward:

Pull down the notifications.

Scroll down to "Select Keyboard" (near the bottom, where else) and activate it.

Oops, all the choices are greyed out in the menu; to enable them, you must slide the "Virtual Keyboard" setting to On.

Oops, now the entire menu disappears just because you used this slider. Like toilet paper, it's single-use only! Anyway, the software keyboard appears. You must pull down the notifications again and activate "Select Keyboard". This time the menu items are enabled.

Pick the soft keyboard you want.

Activate the menu again, and set the Virtual Keyboard to Off.

There has to be a better way? Ideally a hot key, like the very convenient Ctrl-Space for changing the hardware keyboard layout.


问:
How to type Japanese hyphen in Samsung Keyboard's Japanese mode?
If we enable the Japanese language in Samsung Keyboard's configuration and switch to it, we can then input Japanese, with proper conversion and completion.

For instance if we type hi, the input is replaced with ひ, and kanji replacements and completions appear at the bottom of the screen. This context is maintained as we add more characters. The part of our input under consideration is underlined until we select a replacement.

However, there appears to be no way to type a word which contains a katakana hyphen. Suppose I want to type, ha-to to obtain the conversion  ハート. The problem is that when the ordinary hyphen is entered, it immediately cancels the conversion/completion search context and causes the は, which was converted from ha to be accepted, followed by an ordinary hyphen.

The desired behavior is to have はー appear, and stay in the conversion mode. Ideally at that point, ハート ought to be in the list of completions. If not, then at least after we type to, so that our input is はーと, then ハート should be available as the substitution.

Google Japanese Input has a hyphen key in the lower right corner for this. Moreover, if you use a hardware keyboard, the ordinary hyphen key serves in this role.  The ordinary hyphen works this way in the Microsoft IME mode on Windows, and in other operating systems' input methods, like Gnome on GNU/Linux and whatnot.

How do we enter katakana words containing the katakana ー using the Japanese mode of Samsung Keyboard?

I'm thinking that perhaps there might exist a pure katakana mode (and a hot key combination to switch to it) in which the - key maps to this character.
