Is it safe to install cyogenMod on my rooted, bricked , then unrooted Samsung Captivate
My Samsung captivate was running the latest version of Android available to it which is 2.3.5 Gingerbread.

I rooted it by installing ClockworkMod Recovery, (flashing zImage using heimdall on Ubuntu), I then installed CyanogenMod 10. It worked up until the point I went and tried to restore the data or db data(can't remember) part of the backup I made in CWM. This broke the ROM I had to revert to a stock ROM I found.

Firmware version: 2.1-update1

Baseband Version: I897ucjf6

I then tried to restore the custom ROM to no avail. The CWM recovery log said something to the extent of I can't re partition the device or mount the device due to a bad sector. The long and short it did not work.

When I start the phone normally, it does not boot. When I hold 2 vol keys the screen looks as if a VGA cable is not connected properly - everything is colorful, but distorted (no text is recognizable).

Is there a way to get an official (or official-ish) version of Android 4.1 on my phone, preferably using Odin 100% of the time so I am not having to boot into recovery and apply update from zip (Although I can do this if needs be).

Should I use Kies Mini to update to Gingerbread and try again?

Should I just forget about my Android 4.1 dream?

I followed this guide the first time I rooted the phone.
I downloaded CyanogenMod 10 from their seemingly official website under the Samsung Captivate section.

How can I get location detection working on my Pocket TV?
I have an Infinitec Pocket TV (PTV1000 running Android 4.0.4, build ICS02A) and none of the location detection settings seem to work.

Whenever I click the my location icon in Google Maps, I get this message:

Please enable a My Location source in system settings

The News and Weather app/widget just says "No weather location available" and has an option to enter my location.

In Settings -> Location services I have both "Google's location service: location determined by wifi" and "Location & Google search: Let Google use your location to improve search results and other services" ticked, which are the only options in there.

I know that this device doesn't have GPS, but the network location features using wifi and IP should still work the same way they do on my non-GPS & non-3G tablet?

问:
Copy application data file from internal memory to sdcard via update.zip script
Unlock pattern has been used too many times on this android device and we don't have username and password. Most probably USB debugging might also be disabled. I can reset wipe data/factory reset from recovery mode, but I want to backup contacts and messages before I do that. Because we don't have username and password, so contacts can't be recovered even if it is synced to Google account (which I think won't be anyway). Only option I have is apply update from sdcard in recovery mode.

So is there any way to write some update script to copy the contacts data file to sdcard and then run it from update.zip?

Or if I can reboot the phone in USB debugging mode through update script as it happens after flashing some kernels?

Or if I can install an APK through update script?

Other details as below (in case if it matters)

Device: Samsung Galaxy S2

Can't update or unroot Droid Bionic, or reinstall deleted apps
Details:

Running Android 2.3.4
System Version  5.9.905.XT875

I rooted my Droid Bionic using SuperOneClick. Stupidly, I didn't backup my ROM at any point before beginning to tinker with it.

The only thing I did that required root access was freeze and delete some bloatware using Root Uninstaller. Every program that I froze or deleted, I first backed up. When an Android update (don't remember which one) was made available and I let it download and install, it simply said "The software update failed!" after rebooting. I went back to unfreeze/install every system app so that the phone was back to it's state before using Root Uninstaller, but two apps won't reinstall. Those apps are "SmartCarDock" and "Social Networking" (The APK is called FriendFeed). When I run the APK for each program, it just says "Application not installed". From what I've gathered from searching, my best guess is that it could be something to do with saved userdata that is preventing the system from installing an app that "should" be installed, but I have no idea where to start.

I also am unable to unroot, presumably because of those two apps.

I know this could have been prevented by backing up the ROM, but, well, I made a mistake.

In general, I am asking because I want to update my Bionic to ICS, so if anyone has answers pertaining to that, all is helpful.

Let me know if more details are needed!

Broken screen, need to boot to original firmware
This is kind of an odd question, but I have a Razr with a broken screen which has safestrap 2.x (maybe .10) installed and CM10 currently booted up, using VNC/ADB/LOTS of patience, I managed to backup all my information in the CM10 partition.

However, I need to boot to the original firmware (the other partition), however since the screen is broken I can't see safestrap windows to do so, what I'm asking for is if someone has screenshots of the safestrap windows that enable me to blindly navigate (since the physical buttons work) through the screens in order to boot to the original firmware, then I will repeat the ADB/VNC process to remove the safestrap traces so I can send it to Motorola.


问:
GPS issues, location permission - one app only
One app (Dino Dominion) will not register location but will express this complaint: "In order to register your location, please turn the location permission setting on in the application settings."

The app itself has permissions (told to me when installed and when Managing Applications) of coarse and fine location. I didn't think these permissions needed "turning on" - other apps are using GPS without problems.

I asked the app developer, but all they said was "You have to turn on location permission on your device" and "GPS needs to be valid on the side of your device."

I couldn't see any relevant settings anywhere. The GPS is working fine. Also, other users of the app seem to have no problems.

I have HTC Nexus One and Android 2.2.2.

WiFi Direct Doesn't Work
I have two Android devices running Android 4.1.1 with the latest OTA update from the manufacturer. I do not have root or any other system-level customizations on either device, just a bunch of very standard apps.

Device 1: Google Nexus 7

Device 2: Motorola Droid Razr Maxx HD

The only way I have found to send a file between these two devices, without the involvement of a third device (router, computer, SD card, ...) is using the Bluetooth file beaming protocol, which is incredibly slow and short-range. I wanted to use WiFi Direct to achieve much greater speed and distance for file transfers, but I can't get WiFi Direct to connect.

I followed all the instructions and read all the comments here but it just doesn't work.

On this screen, I can see the other Android device advertising WiFi Direct:

What I can't seem to do is to get them to connect to each other. I see the request go to the other device, and receive the request pop-up asking me to confirm the connection. I click Accept, and then after a few seconds, the UI on both devices "resets" to the first screen (the screenshot above) with no indication that a connection was successful.

Side-note: NFC doesn't work either and exhibits similar symptoms of the devices "just not being compatible". It's 2013 and I can hold two flagship Android devices right next to eachother and have no way to send files between them any faster than about 100 KB/s bluetooth beaming.

MTP mounts vs USB storage - restrictions
Just got a nexus 4, and tried to copy files from my nexus one to it.  Copying the N1 SD data to my linux box was a breeze, but the N4 doesn't offer simple mounting.  Shows up as a USB Camera, with only access to DCIM.  I was able to find and use mtpfs to mount the device, but even that has some serious limitations.

The software on the phone's end seems to make some decisions for you.  I tried copying a mix of files from the N1's Ringtones directory to a Ringtones directory on the N4, and the N4 decided that mp3's belong in the Music directory, etc.  I couldn't control where stuff went.  Interesting, some flv files that were there went to Ringones, but not the mp3's.  At first I thought the mp3's weren't copied at all.  I was able to fool this logic by copying to Download on the N4.  Anyway, not sure I like the phone making these decisions.

The mtpfs mount didn't allow me to preserve the timestamps on the copied files.  I copied a bunch of pictures (cp -p) from the N1's DCIM/Camera folder to the N4's.  They all came over with the current date/time.  I can see where it'd be a good idea not to allow a usb mount to set the owner or permissions for a file, but the timestamp?  Is there a way around this, or is this just a shortcoming of the linux mtpfs implementation?

Installation of BusyBox on panda board on Android ICS kernel
I am trying to install BusyBox on panda board which has an ICS Android kernel.

pc ./adb shell
target$ cd /system/busybox
target$ ./busybox --install .
target$ ./sh  #here i am getting error like ./sh: precmd: not found```

Save the original sh executable by renaming it, and then create a soft-link to BusyBox sh:```target$ cd /system/bin
target$ mv sh sh.android
target$ ln -s /system/busybox/sh sh```

Export```

How to create duplicate bookmarks in Android?
I'm using the stock browser on my new Samsung S3 mini (Jellybean) and am having trouble with the browser. When I go to the bookmarks page it seems to have two sections, one called "My Device" and one for my Google account, which seems to contain my bookmarks from my desktop Chrome browser.

I have 100 or so bookmarks on my desktop browser since I have a mouse and a nice big screen to go along with it but on my phone I don't expect to be able to browse more than a few very often so I'd like to create a set of bookmarks to access from the phone quickly and easily. I don't want to navigate around the complex directory structure that I have for my desktop.

I'm running into a problem though. It seems that the browser won't let you duplicate any bookmarks. When you try to add them it just says "already in use" if the bookmark exists anywhere under "My Devices" or my Google account and no matter where I'm adding the bookmark.

Have you all run into this problem and how have you solved it? Should I resort to stupid tricks like adding a "#" after all the bookmarks for the mobile version simply to convince the browser that it's a different page when it's not really?

What is the origin and purpose of RS_##.log files?
On my Galaxy S3 (I747, rooted stock ROM, 4.1.1 jellybean), there are a number (currently 66) of files in /data with names following the format RS_##.log, where ## is a 1 or 2 digit number, currently from 0 to 65.

All files are slightly less than 1KB in size and when viewed as text, contain nothing but strings of seemingly random 5 digit numbers, like these.

71608

70944

70096

70376

70944

All files are owned by system and have rw-rw-rw permissions set.

Most of the files have been updated recently (yesterday) and within 1 minute of each other.  The rest were updated just over 2 weeks ago, also all at once.

What exactly is creating these files and what exactly are they logging?

Music stutters on ICS
I'm a big music lover and on my previous phone which was a Galaxy Y with Gingerbread I listen to a lot of stuff, and I've never had a problem.

I bought a new phone, a rebranded Innos D9 which has ICS installed. I tried using my favorite music player on it, UberMusic, but I found out the music stutters for a few seconds every few seconds. I tried other players, and so far only TTPod reduces it so that I'm not bothered by it. I was even told that PowerAmp doesn't have this problem, so I tried it. At first I thought everything's okay, then the thing screeched. Also, the stuttering is more likely to happen when the screen is off and you turn it on while the audio is playing.

I've done some research and found this thread on Google Code. It seems that this problem is on ICS. Now my question is, what can be done to fix this permanently? Is there an app or music player out there that totally doesn't have stuttering for ICS or should I root my phone and do something?

Important Update:

I forgot to mention that the stuttering doesn't appear when I'm listening to the FM radio or when I'm watching videos. Does this mean this could be an OS related problem? Like a setting in the mp3 buffer or something?

How to sync photos from Aperture on Mac to Android?
My photos are stored in Aperture on my Mac. I would like to sync them so they show in Gallery on my Nexus 7.

Restrictions:

I want to sync over USB or, preferably, WiFi. Uploading to a cloud server from the computer then pulling them back on the tablet is no use, given the speed of my connection and the number of photos.

If there's something that syncs to a companion Android app rather than Gallery, that app needs to support Daydream so I can have my photos appear in Photo Table when the tablet is locked.

Manually exporting the photos from Aperture to a folder is no good — I need something automatic that will export new photos when they appear in the selected projects / smart albums.

Switching to iPhoto or Lightroom is also not an option :)

As the photos are mostly 14Mp RAW files, converting to JPG is essential; scaling them down to a smaller size would also be useful.

Is there anything that will do what I want? DoubleTwist doesn't support Aperture yet; Missing Sync is expensive and the trial version refused to pair with my tablet in any case, so I can't see if the Aperture sync is any good with that.

Need fonts of a different language to show up on android or atleast Instapaper
My family is residing in USA and we are from India. Now my mom gets super bored at home! And loves to read the regional online newspaper and magazines from India on the Internet; problem is she doesn't know how to use a computer! Me or my dad has to sit with her and click links for her, I have never heard anyone say a simple back in a browser in so many ways!.

Interestingly, she didn't have a hard time in using my dad's iPhone 4, in which he managed to lose!

I already own a Asus Transformer 300t and I tried to instapaper the websites she visits Gujrat Samachar Sunday Special this she doesnt miss at any chance.

Problem is, those turn up beautifully on the desktop/webapp but the fonts aren't rendered properly on my tablet or any Android device, before I go ahead and get a Nexus 7 or Galaxy Tab 7, can I have this font show up on Android or at least, instapaper.

All I need to do is instapaper every article when I come home in evening (morning time in India, meaning the newspaper just came out), so that she can read it next day and as a trial run on my tablet!,

Also, those websites, at least the one mentioned above, don't implement RSS feeds or else I could have had my Calibre auto generate/fetch daily news and make an e-book every day and download it on the tab. But I also don't know if those fonts will be detected on Kindle app or any app for that matter!

I know I can try having it outputted as PDF but teaching her to go to PDF and then browse; that's too much for me to teach! The instapaper works smoothly, open instapaper, read headlines, tap that and read/scroll/read , press back next article... plus I still got to download that PDF for her to the tablet

Also reason I'm saying Instapaper often is cause only that will detect the actual title of article

How do I connect to a EAP-SIM authenticated network (namely FreeWifi_secure from Free Mobile)?
I am running CyanogenMod 10 (based on Android 4.1.2) on my Motorola Milestone 2.
I just switched to the French mobile carrier Free Mobile. They offer access to their "FreeWifi_secure" wifi network in the plan. The authentication method is known as EAP-SIM ; it connects using information in the SIM card. However, this option is not given when you try to connect using the "Settings" app in Android.

So I tried to connect to the FreeWifi_secure wifi by following a method explained on XDA-Developers.com. It consists in adding the following lines to /data/misc/wifi/wpa_supplicant.conf :

```<code>network={
    ssid="FreeWifi_secure"
    key_mgmt=WPA-EAP IEEE8021X
    eap=SIM
    priority=70
}
</code>```

I managed to follow the instructions but still cannot connect to the wifi network. FreeWifi_secure is correctly displayed as a favorite network, however, when trying to connect, it never goes past the "Connecting…" step.

Do you know whether the Milestone 2 is hardwarewise compatible with EAP-SIM ? Or is the incompatibility due to a software limitation in CyanogenMod ? Have you personally managed to use the Free Mobile wifi network ?

Nexus 7 boot loop
I'm not certain if this is the same as the other two questions about boot loop on the nexus 7,  but I have a nexus 7 that goes into a boot loop. It boots to the point of the unlock screen, then it sits there unresponsive for a couple of seconds before rebooting. I'm running 4.2, and the bootloader is locked.

Package cannot be (re-)installed or uninstalled
My device is a non-rooted device. I was trying to install SDMove.apk (sideload) from my ICS tablet.

What is meant by System Memory in android?
I have an LG -E405 phone running Android 2.3.6.

As can be seen here, the phone has 1GB internal memory and 384Mb RAM.

When I look at default App manager, this is what I get,

RAM - 231Mb

System Memory - 157 Mb.

Internal Memory - 378Mb.

SD Card - 2Gb.

Also, all the applications I install, by default take up space from System memory.

Many tutorials explain about moving apps from internal memory to SD Card to free up space.

But, in my phone I only get the option to move from System Memory to Internal Memory.

It is like a whole new layer has been added in the memory heirarchy.

So, what is this System Memory.

Android Tablet (Sony Tablet S) with USB Barcode Scanner
I have a USB barcode scanner which, when plugged into a Windows PC works fine, just as a keyboard it 'types' the barcode into whatever software is open.

I am attempting to use this with an Android tablet (Sony Tablet S running ICS 4.0.3) - to no avail.  I can plug in a USB Keyboard and that works fine, but the scanner just doesn't work. (I get a beep when scanning, then the laser goes out and won't react to any further presses of the trigger until I unplug the USB cable.)

Any ideas? I've tried with a Nexus 7 and that works fine. Surprised it doesn't on the Sony as I thought the scanners just emulated a Keyboard anyway. If no specific solutions, is there any reason to be hopeful that the upcoming Jelly Bean update for the Sony could help? (Nexus is JB) or is it more likely to be hardware related?

My phone crashes while charging
My phone sometimes shuts down without a reason or warning. It often happens while it's charging. I'm not positive charging is an absolute requirement for this to happen, but I only remember it happening in that situation.

Then I go to it and find it not responding, just showing a battery filling up or filled up: it's charging while turned off. But I didn't turn it off, and it was still turned on when I plugged it in.

Sometimes, I can leave my phone like that a whole afternoon, noticing only after 3-4 hours that something is wrong. At that point, my phone has been turned off for an unknown amount of time, and who knows who could have tried to call me.

What is causing this? Is there a way to prevent it? Or to automatically turn the phone back on when it crashes like that?

My phone:

Samsung Galaxy Q (SGH-T589W)

Android 2.3.6 Gingerbread

Processor: 600MHz Qualcomm MSM7227 (if indeed it's the same as the Gravity Smart, because information on the Galaxy Q is rare)

Internal storage: 152 MB, some of which I think is taken up by the OS or useless stock software, because I can't ever seem to free it

OpenVPN Tunneling Facebook/Gmail App
I recently downloaded the OpenVPN app and I have it setup to connect to a server at my house and all of my HTTP(S) traffic is tunneled through the connection. I have confirmed this by going to ipchicken.com and it shows the correct public IP. Under the OpenVPN settings I have the "use system proxy" box checked. My question is does that pertain to the Facebook and Gmail apps as well? I would assume the apps are just using HTTPS to connect and then display them but wasn't 100% sure.

On a side note, for some reason every time I connect to my VPN on the cell network, it pushes me my correct 192.168.1.0/24 route that my server is handing out but it also pushes a 10.109.105.209/255.255.255.240 route. This is not defined anywhere in my setup and doesn't show up when I connect to my VPN through another WiFi network. It is solely linked to the cell network. Everything still works fine but was curious why it did this.

Thanks in advance,

E-mail (imap client) sync stopped because of low memory, and will not start again, even after freeing 60Mb
I have a Motorola XT303 running Android 2.3.6, and I use the email client (with an IMAP server). The email worked fine until two days ago: I tried to download an application that was too large for the internal memory, and the installation failed. Right after that email syncing stopped -- whenever I asked it to sync, a message popped up telling me that email syncing wouldn't be done because the phone was low on memory. However, even after freeing 60Mb of internal memory, the email client still refuses to sync.

I have tried stopping the email app from the task manager and restarting the phone, but that didn't help.

I also thought I'd just download another email client, but since this is software that will have access to my email server passwords, I'd rather use the client I'm already using.

edit: but if there is an email client that is open source and well-known, then I could just as well switch...

So... How can I get the email app to start syncing again?

Resetting Nexus 4 with cracked and Locked Screen

Possible Duplicate:

  How do I backup data (sms/contacts) from a device with a broken screen?

My Nexus 4 fell and cracked its screen:

One of the caveats in its design is the glass on the back makes it slide down and fall from pretty much any surface.

Another caveat is the curved unprotected glass on the front. If it falls down, it'll most likely crack.

Given

After it fell, the phone "lost its touch" i.e. it does not respond to any "touching".

It is not rooted, the screen is (pattern) locked, hence I can neither see the files via MTP nor can do:

```<code>adb shell rm /data/system/gesture.key
</code>```

since permission is denied. I am also unable to

```<code>adb pull /data/data/com.android.providers.contacts/databases
</code>```

to save my messages, configs, etc.. for the same reason.

The only thing I have backed up is pictures (which of course is "something"):

```<code>adb pull /sdcard/ /destination
</code>```

Question(s)

I need to back up and reset it before shipping it back.

How do I go about backing up the "databases" (e.g. SMS, configs, etc)?

How do I wipe it clean, so whoever gets it can't get my data?

EDIT

Since this is closed as duplicate, which it's really not, here is the solution to this problem in case somebody else is looking for it.

My only thought was to boot from a liveCD and take a look at the grub config files, but I cannot actually look at the hard drive in the tablet from the liveCD, since I don't have write permissions and thus cannot use the mount command.

If anyone has any idea as to what I could do to get grub to boot android from the hard drive, I'd appreciate it.  Thanks beforehand!

Normally this is just displaying a web page with status information (currently using Kiosk Browser for this), however, we were thinking it would be nice to have the ability to display a screen/app from someone's PC on the wallboard.

Remotely, from one of several workstations, initiate the display -- ideally without any action needed on the Android device, or at least with something simple like a 'Yes/No' confirm prompt that can selected using the Pivos IR remote.

Ideally once the PC ends the session, the wallboard goes back to Kiosk display. Less ideally, it's easy to return using the IR remote.

This may be a combination several things/apps that need to be done, I am just not sure what they'd be.

Remember, I am trying to display something from a PC on the Android device, shared among several people. This means:

Something that uses Google Accounts for authentication/connection won't work, since this is shared among several people (who likely are logged into their own Google accounts using Chrome)

If I press Cancel sync I used to get a toast saying that there are temporary problems and to try later (I think the message was "sync is currently experiencing problems. It will be back shortly"). But now nothing happens when I press Cancel sync.

Deleting all the Google contact data in the phone and then re-syncing is not an option for two reasons:

If the problem is with a contact in the server then it won't fix the issue

I don't want to risk losing data that I added on the phone and wasn't sent to the server yet.

I turned on developer mode to get ADB logs; the following line seemed the most relevant (repeated 8 times):

```<code>D/ContactsSyncAdapter( 2964): IOException: java.io.IOException: received unhandled http error: 500
</code>```

then followed by

```<code>D/SyncManager( 2257): failed sync operation , SyncResult: stats [ numIoExceptions: 8]
</code>```

I think that there are 8 contacts that somehow are not able to be synchronized, but I can't really find out which ones. Finding the HTTP requests that end with a 500 error could potentially reveal which contacts might be causing trouble or more troubleshooting clues.

I'd like to avoid rooting my phone, but I do have a full Android SDK and source environment set up. I've tried using DDMS but haven't been able to make it show if/which requests are being sent to the server.

问:
map physical button to auto-rotate switch in android?
I would like to map the auto-rotate lock toggle/switch/setting to a physical button in a device. how do I do that?

On the linux side of android, in linux/input.h, there are different KEY events, SW(switch) events and a lot more. fortunately, the rotation lock is there(SW_ROTATION_LOCK), however it is a switch event type, not a key event type...

Looking in my key layout file (.kl file), all items that are listed there are key events...

On the other hand, the assigned events to these keys are constants in the android framework. looking at http://developer.android.com/reference/android/view/KeyEvent.html where valid key maps are listed, I assume.

What I have done:
Registered the physical button to recieve the rotation lock as a switch event on the board configuration settings... (imx6 board) all that's left is on the android side I believe..

so, anyone knows how to map the button to auto-rotation lock/switch?

Can I change the handset software operator?
I have an HTC One X on the Orange network here in the UK.

I sent my phone off for repair due to a bad screen. When it has come back 3 weeks later it seems to have been reloaded with T-Mobile software! My old Sim card will not work as it says it is network locked, and is asking for an 8 character unlock code.

I don't want to jailbreak it or anything like that, just get the Orange software on it instead of the T-Mobile software.

Is this something I can easily do, or should I just bite the bullet and send it away for another 3 weeks?

Nexus 7 and Samsung Ace S5830i does not connect properlly to Wifi
I have three devices:

Tablet running on Android 4.0 (Nexus 7)

Smartphone running on 2.0 (Samsung Ace S5830i)

HP Compaq laptop

Wireless router does have WPA/WPA2 PSK security. And the Wifi works perfectly fine on the laptop.

Now both the tablet and the phone does connect to the Wifi but at times does not allow me to browse or do anything. i.e cannot download anything.

My tablet keeps getting disconnected and then it re-connects back automatically, this happens randomly and erratically. Same experience with the Android phone.

I called the telecoms engineer and he resetted the router etc., and said there has to be something wrong with my tablet!!! But I am sure there is not.

I have browsed through some posts which suggests me to change MAC settings and to change the encryption settings, but I have no idea what that is, nor where to find it.

Would love if this could be sorted as its really frustrating.

Meanwhile I understand Nexus 7 runs on 2.4Ghz Wifi band frequency, where as most of the modern routers comes with 5.0Ghz Wifi band frequency, but then, again my smartphone runs on the 5.0Ghz Wifi band frequency, and still doesn't function!!

Verizon Galaxy Nexus Discharging When Plugged In Even After USB Replacement
I've got a Verizon Samsung Galaxy Nexus that as of a few weeks ago quit charging - in fact it quickly drains the battery (discharges 2% / minute if not more) while plugged in. I tried different batteries, cords, chargers, over USB, etc, no difference. I went ahead and followed these instructions to replace the Micro USB port and I'm still having the same issue. The interesting thing is that computers recognize the phone via USB but the battery still shows "Discharging" and the battery drains extremely quickly. I have even tried charging via the pins on the side of the phone ("pogo pins" charging) and exhibits the same symptoms as traditional charging. This leads me to believe the charging circuit itself is damaged, instead of just the USB port.

Anyone have any tips or references on what else to troubleshoot or have any specs on the charging circuit itself that I could poke around with? I have a decent amount of electronics knowledge and don't mind getting my hands dirty. I am getting by with spare batteries and an external battery charger right now, but it is quite a hassle.

I would like to know whether it is possible to not simply search for my avahi-enabled computer, but also to ssh to it via my ssh-android-terminal.

I'm also referring to this question asked on Ubuntu forums

From my iPad it is possible to ssh to my Ubuntu machine, but what is missing on android-side to enable this for android? Do I have to install some kind of bonjour-service or similar?

The thing is:
I sure could install a full dns-service on my Ubuntu, but I wanted to know whether I could simply use avahi/zeroconf instead. As I said above: with an iPad it us possible to connect to my Ubuntu machine by simply entering in ssh-terminal as host/IP: MyHostName.local
So my question still is: why is this not possible with android?

Sure I could use a zeroconf-browser-app that resolves the .local-adress to the actual IP. But that would be an extra step to make which is not needed on iOS... the ssh-terminal app on iOS can resolve .local itself! So do I need a terminal app that can do same? Until now I tried almost all, there aren't so many...

I hope this explains my issue a bit better.
And I don't think my question has been answered somewhere else before, as far as I can tell.

I'm not sure on how to proceed... Should I append my question to another question? Or is it just my bad explanation? :/

My bluetooth keyboard's skip/back buttons don't fast forward/rewind
I recently purchased Satechi's Bluetooth Multimedia Remote Control so I could control my music without looking (i.e. without removing my hands from my pockets and exposing them to winter). Essentially, this pairs as a bluetooth keyboard with media keys, which is why I said "bluetooth keyboard" in title, because I imagine it is functionally the same.

Here's my problem: pressing and holding the skip button does not fast forward as expected (likewise for the back button and rewinding). I noticed that the default music app immediately skips when the button is pressed, while the doubleTwist app waits until the button is released to skip; this makes me think that each app decides how to handle the input from the media keys. Any suggestions for a workaround or an app that will respond appropriately to my input?

App2SD doesn't work - I don't even have the option
So I got a Verizon Samsung Stellar (it has Android 4.0.2) a few days ago. All's going well, but I don't have the option to transfer an app to my sd card. However, I can move files etc with a file manager, so the phone recognizes the SD card is there.

On my old phone (an ancient MyTouch 4G, it was 2.3.4) there was a button in the Application Manager to move an app to the SD card. If the app didn't have App2SD supported it would be grayed out.

I called Verizon to see why I don't have this option on my newer phone (you think that with a 1GB internal hard drive and an included SD card they would support moving apps to your SD) and the person said that I just hold down the app name and a bar would come up with options. Holding down an app did nothing, no quick vibrations like when you move an icon on your home screen, etc. I've looked and about 80% of apps I have support App2SD so it's not that. How do I fix this?

问:
In what version of Android was process caching first implemented?
Android can cache app processes to improve start-up times for subsequent app executions.

You can see this capability on some devices by going to Settings->Applications->Manage Applications (or just Settings->Apps on others), going to the "Running" applications tab, and either pressing the Menu button or another button on the UI marked with the option to Show cached processes.

Here's a list of devices I've looked at to see if this "Show cached processes" menu item is available:

HTC Hero (Android 2.1-update1) - No

HTC T-Mobile MyTouch 3G Slide (Android 2.1-update1) - No

Samsung Dart (Android 2.2) - No

HTC EVO 4G (Android 2.3.3) - Yes

HTC EVO Shift (Android 2.3.4) - Yes

HTC EVO 3D (Android 4.0.3) - Yes

Samsung Nexus S 4G (Android 4.1.1) - Yes

Samsung Galaxy S3 (Android 4.1.1) - Yes

Based on these devices, it looks like process caching became visible to the user in Android 2.3.

So, the question:

In what version of Android was process caching first introduced (even if its not visible to the user)?

Any answers with strong evidence (e.g., Android documentation or AOSP source code references, 1st person observations of devices) are appreciated.

Galaxy S3 - high minimum volume through headphones
I recently purchased a UK Samsung Galaxy S3 running Android 4.1.2, intending to replace my iPod as a music player. However, even with the volume slider on its lowest non-zero setting, the volume through my earphones is equivalent to about 45% on my old iPod Touch (or about 30% with all the sound enhancements/equalizer settings turned off). This is far too high for listening in an otherwise quiet room, and is physically painful with louder songs.

Whilst I know there is at least one app which gives finer control of media volume, it requires actually opening a separate app every time you want to adjust the volume. I was wondering if there was a more system-level solution to either provide finer control with the volume buttons/slider or somehow scale-down the volume in general when earphones are connected?

Possible security issues with having debug mode enabled?
Are there any significant security concerns with having a phone with debug mode enabled 24/7? As I understand it the debug mode only really becomes active once the phone is connected via USB cable to a computer with the adb driver which would basically limit the security concerns to malicious programs being installed on a computer and waiting for a phone to connect?

Or are there any other security issues involved that enables apps on the phone themselves to do anything, Bluetooth or WiFi exploits or something similar?

desktop shortcut that takes a photo and emails it to a fixed address
I am registered with a website that can archive scans of receipts.  One way to upload the receipt image is to email it to an email address that's tied to my account.

To expedite the process, I want a shortcut on my Android desktop that, when pressed, starts the camera, lets me take & review the photo, and then emails the photo to a fixed email address.  I've found lots of apps that take photos and automatically upload them to your favorite photo sharing site, but I haven't run across any that will send them to a pre-configured address.

Input via voice and handwritten works, but not keyboard on app on Galaxy 2
I am working within an app that has text fields for entry.  I can highlight and cut the text if it auto-populates and I can even use the text-to-speech and handwriting input methods.  When I use the keyboard to type, however, it does not populate the text field.  Any thoughts on why this would happen?  </p>


问:
Keyboard shows when getting an incoming call
I have an LG Nexus 4 running Android 4.2.1 and have a strange problem. When I got an incoming phone call the keyboard is displayed and won't go away. This is a rather big problem since it obscures the area which allows me to accept the phone call.

Is there anyway in which I can stop this happening? This is my first Android device so I am still pretty new to it.

Google Now Choosing Weird Route
For at least a month or two, my Razr Maxx HD running the stock firmware Android 4.1.1 (9.1.41.XT926.Verizon.en.US) has done a great job at telling me how long it'll take to get home.

I know the route and don't need it to navigate me, obviously, but it has been picking the route that I actually follow. It gives me an estimated time for getting home, so that I can plan my evening around whether there's a severe problem on my route (traffic, road closure, construction, accident, etc.) and either route around it, or let others know that I'll be late, or if it's really terrible, stop somewhere for dinner before hitting the highway.

Suddenly, without changing my route or my driving habits at all, Google Now is telling me that it will take about three times longer to get home, and through an extremely indirect / inefficient route. So the time to home is very inaccurate because it isn't basing it on the correct route. Moreover, when I check other sources of traffic information online, I have no evidence that there is any sort of significant delay on my primary route -- at least, nothing significant enough that would make the alternate route faster, or even close to the same time (my primary route is one that takes about 25 minutes at full speed, 35 minutes in typical traffic, 60 minutes with a moderate to severe accident; the alternate route is saying 85 minutes!)

I double checked the settings for the Google Now traffic card, and the home and work addresses are set correctly. Google Navigation app picks the fastest route (the route I actually drive) when I ask it to take me home. So, why is Google Now telling me it'll take me an extremely long time to get home via an alternate route? Is there any way for me to set the route manually?

How can I sync my Contacts with Gmail if the stock firmware of my phone doesn't provide this feature?
Am using a Grandstream GXP2200 Android deskphone that has a customized version of 2.3.5 on it. They have replaced the native contacts app with a custom one that doesn't sync with Gmail. I have replaced this with GO Contacts, but had to manually import contacts into GO. The phone has Google Play on it and I can install apps readily. How can I sync my contacts?</p>

How to activate usb port, -sc3 usb host driver not found
I have an unbranded rck30sdk tablet running Android 4.1.1. I have run USB diagnostics, plus host controller which gives me the messages:

sc3 usb host driver not found, root hub present, usb host mode is active.

How can i resolve this? Basically I want to connect my dslr to view/download images. I am reasonably computer literate, but have no experience of programming etc. I found one answer that mentioned inserting a new command via the system, permissions etc. I found these via x-plore, but only as a read-only option.

Can you give me any advice what I could do?

Phone won't turn on after attempting to upgrade Galaxy S to ICS
I tried upgrading my Galaxy S to ICS like I did my Galaxy S2.

I used the exact same steps. However, Odin froze and shut down. So, I unplugged the phone, powered off, and went to power back on in download mode. It didn't show any signs of life now. I've taken out the battery, put back in, but still nothing. When I plug it in, it doesn't even come up with the charging symbol.

Please help.
