Send a Double type variable as an extra when sending an intent via adb shell
I wish to send a Double variable as an extra. It is easy to do with code but it seems that am can't do it.

Below is the am extra help, we can see that there are flags for int, long and even float but no double.

```<code><INTENT> specifications include these flags and arguments:

Here is how i am trying to do it :

```<code>adb shell am startservice -a com.incorporateapps.fakegps.ENGAGE -e lat 5.1234 -e lng 1.333
</code>```

I tried with all the flags available but no results achieved. The intent is sent successfully but the extras are not used because the app expect them to be double and probably get them with the getDouble(). I tried this with Tasker and this is working properly because i can add a "D" at the end to tell tasker it has to send a double.

Any idea ?

chroot: can't execute /init.sh: Permission denied - Error while want to start linux on Android
Introduction:

I formatted a SDCard in ext4 and copied an ArchVersion on it to run it from Android like in this guide (step 7). Of course my device is rooted and I am running the following scripts and commands in the Terminal Emulator as superuser.

Device-info:

Phone: Sony Xperia Z1

Model number: C6903

Android version: 5.1.1

Build Number: 14.6.A.1.236

Issue:

After executing sh storage/emulated/0/linux/linux.sh 2> storage/emulated/0/linux/output.txtthe device ends up in Android again because the command chroot /data/local/mnt /init.sh can't execute /init.sh: Permission denied.

linux.sh:

```<code>#!/system/bin/sh

export LINUXROOT=/data/local/mnt
export TMPDIR=/tmp
export HOME=/root
export USER=root
export PATH=/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:$PATH
export TERM=vt100

sh ./mount.sh # works fine
sh ./stopandroid.sh # works fine

echo "******* Your chroot-environment is starting now ********"
chroot $LINUXROOT /init.sh # can't execute /init.sh: Permission denied
echo "******* You exited the chroot-environment, unmounting... ********"

sh ./umount.sh
sh ./startandroid.sh

echo " ## DONE"
</code>```

I already found some posts about this issue together with LinuxonAndroid and BusyBox. I do not use LinuxonAndroid and installed BusyBox from Google Play Store which should solve the problem when running another BusyBox-version what I do not.

Like it is stated here it may require to chmod 0755 /data/data/com.zpwebsites.linuxonandroid/files/busybox which is not possible in my case, because obviously the folder com.zpwebsites.linuxonandroid does not exist.

So I searched for busybox inside /data/data, found one file and changed permission: chmod 0777 data/data/stericson.busybox/files/bb/busybox.

I also changed the permissions of init.sh: chmod 777 init.sh

I also tried to run the command chroot /data/local/mnt /init.sh in the terminal with the same result.

After these changes I really do not have a clue whats wrong.

Any suggestions?

Can I still use live.com for my contacts 'hub' on Android?
I'm switching from a Lumia 1020 (Windows Phone 8.1) to a OnePlus3 (Android M I think).
I bought into the MS live.com setup for contacts so all my contact phone numbers and addresses and facebook maappings are there, however I also have a gmail account which is where all my email contacts are stored.

I'm worried it's all going to be a big mess, I read this already: Switching contacts from Windows Phone to Android

I did wonder though, do I have to use Google for my contacts on Android or can I continue with Live.com? Maybe that sounds a stupid idea (I'm new to android) but I do use OneNote extensively as well as Google Drive and Gmail so I have a foot in both camps.

Is a manual dump of contacts the best way to go in 2016? I was rather expecting my new phone would let me sign into my live.com account and slurp all the contacts!

Unlock problem with HTC Desire

The screen lights on with HTC start screen (HTC quietly brillant) then the home screen of the telephone is displayed.

There is a first problem because all my widgets and apps on my home screen aren't displayed. Unfortunately, this is not my main problem.

When the telephone is locked, when I want to unlock by push Power button like usual, the keys to the bottom of the telephone light on but the screen stays black ! The telephone is well unlocked because when I try to increase volume there is the sound of that action.

So, I don't understand very well the problem :(.

Configuring Android to IP FORWARDING
Android version : Lollipop. Rooted: Yes.

I'm trying to connect a PC to a Laptop via a WLAN.

I'm using my android as a WifiAdapter. I connected the android node to the WLAN. With a USB cable connected to the PC, and enable tethering.

So it's something like this : PC -- USB Cable --> Android --> (( WLAN )) <-- Laptop

Also enable ip-forwarding on the android

```<code>    echo 1 > /proc/sys/net/ipv4/ip_forwarding

Laptop replied to an echo message from PC:

```<code>    PC$ ping LAPTOP_IP -n 1
    32 bytes from LAPTOP_IP: icmp_seq=1 ttl=63 time=14.0 ms
</code>```

I can start a connection on port 22 from Android to Laptop (using telnet because I currently don't have a ssh-client installed on the Android).

```<code>    1|root@osprey_umts:/ # telnet LAPTOP_IP
    SSH-2.0-OpenSSH_6.7p1 Debian-5+deb8u2
</code>```

But I can't start a connection to the Laptop from the PC throught that port.

On the laptop I have no iptables-rule:

```<code>    root@laptop$ iptables -nvl
    Chain INPUT (policy ACCEPT 742 packets, 60749 bytes)
     pkts bytes target     prot opt in     out     source               destination

I can't make it work

Internal GPS interfering with mock locations?
I've been using mock locations in my latest endeavors, and I'm having some issues. I enabled a mock location app from the developer options, set my Location Mode to 'Device Only,' and took precautions such as moving the app to System.

Everything is working how I intended it, except my location keeps bouncing between the mock location and my actual location. I've tried desperately to prevent my internal GPS from interfering with the mocked location, but with no luck.

The only method that I managed to have success with was by wrapping aluminum foil around my phone to inhibit the GPS.. this works but it's very inconvenient. I'd be grateful to anyone who can shine light on my troubles.

I'm running rooted Android 6.01 (Marshmallow) with a OnePlus Two device if it matters. I've tried different mock location apps with similar results on them all.

Why my hosts file is not saving/resetting after editing it?
I need to add # before the command line (so I can login into my google account which is a common problem).

I rooted my device (I'm using a huawei P8) and tried using total commander and root explorer, both no success. With root explorer, I used mount r/w in the etc folder. Basically, after editing the hosts file and restart the device, the file looks like it didn't change or it resetted. Even before restart the device I checked the file again (because I suspected that it just didn't save or something) and I saw the file didn't change.

Is the WiFi-communication during installation harming my privacy?
I want to use Android (6.0 / marshmallow) on my new device (OnePlus 3) and want to set it up as google-free as possible (as example). By default, I am forced to set up a Wi-Fi network when I boot my phone initially (or after a factory reset).

I intend to disable google services and won't use a google account. I am interested in any evidence that the communicated data during the install process does already harm my privacy protection efforts (i.e. transmitting some ID to google to track me or my device).
Does anyone know if that is the case in the set up process (i.e. did someone invest this further with wireshark etc. already?)

Update: After a hard reset and new try to set it up, there is the message "This device was reset. To continue, sign in with a Google Account that was previously synced on this device." So there seems to be some anti theft magic, which also raises privacy concerns.

Decryption process was interrupted and "Device memory damaged" message is shown.
-Phone model: Samsung Galaxy Note 4

-Rooted.

-USB debuging was active before the problem.

-TWRP is installed. version 3.0.2-0.

-rom is stock android forgot the version.

-I know the encryption key.

It has been a week that Im trying to recover and couldnt do yet.

Here is the summary of the story.

Problem:

I encrypted the phone and due to the lack of performance wanted to take the encryption off (decrypt it). For some reason decryption didnt end even after 15 hours. It was obvious that there was a problem. it was stack on the samsung logo. So I decided to reboot it.
It said "Device memory damaged.The data partition has been corrupted. You need to reset your device to factory defaults. "

when I open in recovery mode via TWRP it says
Failed to mount '/data' (invalid argument)
Unable to recreate /data/media folder.
Unable to mount /data/media/TWRP/.twrps

When I tried to wipe only system data it also gives the same error.

What I have found so far?

Most of the methods includes wiping before getting backup. However I know the encryption key and I want to recover my files.
Some of the topics also says there is no way to recover this data, but until this day whenever someone said its not recoverable I always found a way to recover. This is linux and I believe there should be a way to recover this data since I have a encryption key. It shouldnt be that hard. My files are inside internal memory.

What I have tried?

I tried to follow this topic on xdadev. To do this I installed ubuntu on virtual machine. After some processes I managed to get a backup of /userdata directory which was located at /mmcblk0p27. However it cant be mounted and it cannot be repaired with e2fsck -f -y command.

So I'm stacked. I dont know how to recover this data. Any ideas?

Is there to set screen resolution/screen density by app?
I have a rooted Z3 compact running Android 5.0.2.

I've been using the Resolution Changer app to set my screen resolution, as I find it makes a huge difference in screen real estate and aesthetics. But a couple of apps don't seem to like it (menus appear strange, some text not displayed at all etc).

Is there a way (app, setting etc) to make it so that specific apps run on specific resolutions or at least, a screen resolution/density changer that lets you choose apps on which to ignore that setting?

My goal is to be able to have a specific resolution set for certain apps and have others display in the original resolution my phone has in its factory setting.

I'm hoping that's possible as I remember running custom ROMs on previous Android phones I've had that had different resolutions for some applications.

Google Play auto-update of other apps causes YouTube video to pause
I have set my Google Play to automatically update apps when the phone charging and connected to WiFi. This is convenient to keep apps up-to-date.

The problem is, I may also want to watch new videos from my YouTube subscriptions right after I plugged the phone in to charge. But the auto-update kicks in and after each app update is installed, the video in YouTube suddenly pauses. I can tap Play to resume the video, but the video pauses again after the next update is installed.

It doesn't matter what apps are being updated. If there are 15 apps getting updated while I play a long video, the video will pause 15 times!

I should add that there is no update for YouTube app itself. The updates are for other apps and it doesn't matter which app is updated. Every single update causes a playing YouTube video to pause. YouTube doesn't quit and it's still on screen, just the video gets paused.

My device is OnePlus 2 running on latest stock Marshmallow. I'm not sure if this is device specific.

Is there any way to fix this?

I have recently switched to Android from iOS and have run into a problem regarding receiving MMS messages on the phone.

Previously on iPhone, I was able to receive HTML MMS messages by sending them base64 encoded with the following MIME headers:

Content-Transfer-Encoding: base64;
Content-Disposition: inline; filename="html.html";

These would come in as HTML files which would thus be interpreted by iOS's built in browser upon clicking them.

Xperia Z3 Android 6.0 : How to share my computer internet with USB?
Having troubles sharing my internet connection from my desktop computer to my Xperia Z3 compact phone. I went to Settings -> Network connections -> USB connection. From this post (a bit old, it's meant for KitKat and not Marshmallow), I expected to view an option like USB internet. But there is only an option called Software install that I checked. But what software is this option about and how to install it, I don't get it.

I tried to connect my phone to my Windows 10 computer after checking the option, nothing special comes, no software install. I can choose several options :

charging only

transfer files (MTP)

mass storage (MSC)

MIDI

Choosing MTP, I can move files from my computer to my phone. But unlike what is presented in this post, no additional network connection do appear on my computer. I tried to share my connection (because my computer have two Ethernet ports, I can activate it anyway), but that does not work. No internet on my phone.

Sorry if the menus or options from this post are not strictly the same in the english version, my phone is in another language. Anyway, What I describe should be clear enough (otherwise just say, I'll explain more deeply).

Why won't Adoptable Storage work on my H811 LG G4?
I have an H811 LG G4 running the latest patches (20o) and can't get my adoptable storage to work for a 64G external SD card I plugged in. I've found a lot of info about bunk SD cards as well as many claims that LG has disabled adoptable storage/external SD because they didn't want a bunch of whining about performance hits. However, just as much info out there from people with this same device who do have access to their external SD card. One reddit thread I ran across showed how to use the sm command to enable adoptable storage. I can't seem to get this working however. The SD card I'm using is a Samsung EVO Class 10 and I am able to mount it and format it under Linux just fine. I have also tried using a different SD card known to be working in a camera with a VFAT filesystem on it. Again, works fine in Linux, fine in the camera, but LG G4 doesn't see it. I've checked dmesg output and have attached it grepping for mmc. It seems like the device is seeing two SD cards and one is throwing a error -110 which google says is a timeout. Any thoughts?

This is the output of sm command:

```<code>   root@p1:/sdcard/tmo_update # sm has-adoptable
    true
    root@p1:/sdcard/tmo_update # sm list-disks adoptable
    root@p1:/sdcard/tmo_update # sm list-disks
    root@p1:/sdcard/tmo_update # sm get-primary-storage-uuid
    null
    root@p1:/sdcard/tmo_update # sm list-volumes all
    private mounted null
    emulated mounted null
</code>```

Here is dmesg output:

问:
Log what an application does and accesses
I'm a bit paranoid about the permissions that certain applications require to work on an Android phone. Specially the "Access to your storage" permission. What I'm scared of is if an application is able to access the internet and is able to access my personal data, it could simply upload it to a unknown destination.

Since I don't know much in Android, I wanted to ask if it would be possible to "log " what an apps is doing on your phone, something like:

ThisApp entered this folder

ThisApp used this file

etc...

Is there any way to do something as I've described above?

问:
/TASKER/ Voice Command on Bluetooth Connect
Got a new bluetooth radio in my car and want to add voice control when it is connected.

I was thinking that when it either first connects it listens once so I can open up the music app of my choice or to have it constantly listening though I don't know how smooth that would work out.

Any ideas? I already have it setup to disable the unlock screen and open Slacker.  Want to do this cause I still have to look at my phone occassionally and want to try not to.


问:
Use accounts on the device permission - please clarify when needed
I've read this: What can an app do with the "USE ACCOUNTS ON THE DEVICE" permission??

In the main answer (by Dan) it's said:

The AccountManager then asks
  you if you want the requesting app (YouTube) to be able to use the

How to get rid of NFC icon?
After a forced OS reinstall by a repair shop a Sony Xperia Z5 Compact started to show a NFC icon in a status bar.
How to get rid of it? It does not give any information as it is always on, so it is just annoying.

The icon is not an option in Display / System Icons

Any other Xperia (even with same OS 5.1.1) does not have it, including this one before the service

in build.prop it is turned off by ro.nfc.icon.enable=false

NFC should be on, I use it, but the icon should be hidden like it was, because there is no info in showing it and clutter the status bar

Brutal bug "android.process.acore has stopped" doesn't solve after factory reset
Apparently this bug is prevalent and some are lucky enough to solve it by simply clearing data of Contacts storage but not me. I believe I have tried it all. Even after factory reset (via stock recovery) this error appears immediately after first boot and it keeps popping up non-stop making the phone very hard to use.

Does anyone know a solid fix for this brutal bug?

Resize /system partition of Galaxy S4 Mini
I have a Samsung S4 Mini GT-i9195 and recently I've updated it to CyanogenMod 13, it was stuck on Android 4.4.

The /system partition has 1.5GB and it was full with the stock ROM. After updating to CyanogenMod, I got only 600MB occupied and 900MB free. How can I resize the parition to, let's say 800MB, and add the remaining space to the /data partition?

I've found this answer for a very similar question, but I'm not sure if that procedure suits to my phone and I don't know how to create the PIT file. I'm already able to backup it from the phone and edit it with PIT Magic. But I don't know if I can do it with this tool or even how to do it...

Any suggestions?

One icon keeps vanishing from home screen
I have looked around for similar issue but I think mine is different.  Now and then, only 1 icon vanishes from my home screen.  It is always "Aces Cribbage" (available on Google store for free) and sometimes it won't come back after restarting. It is currently set installed on the main memory and not SD card so that is ruled out.  I have removed and reinstalled it and cleared cache.

I have a few other apps and games installed that are not having this issue (some on SD cards, some on only main memory) so I wonder if there's something with Aces Cribbage that is glitching the home screen icon?

Once in a blue moon, the icon reappears behind another icon, forcing me to rearrange a few to get that game back out and accessible again. When it is missing and I want to play it, I have to use apps screen to find the game, which is a couple steps more than having it stay on the home screen.

Sony Z GPS issue (maybe after root)
Apps on Sony Z could not find location using GPS after even like 15 minutes (about max I waited). I did not use location for some time, during which one thing I did is making root via Wondershare MobileGo.

Factory data reset did not help - neither it undid root access.

System check via *#*#7378423#*#* finds GPS location - in less then a minute.

I disabled and hide root via SuperSU app and still maps could not find location.

What could be done to help apps find location?

ADDED:
Installed GPS Test app. GPS Test is finding satellites after several minutes. After satellites are found by GPS Test, maps (e.g. MAPS.ME) start working (Pokemon Go still says 'No GPS').
Still interested why location is not working w/out such trick and what can be done about it.

Backup creates basically empty file
I am very tired of all the Samsung bloatware imposed on me so I am trying to back up my data prior to rooting the phone and cleaning it up.

There are numerous claims on the internet that this is done using this adb command:

```<code>adb backup -apk -shared -all -system -f myBackupAndroid.ab
</code>```

Some also suggested adding backslashes before spaces after the backup. That didn't affect my results, which is (basically) empty file:

This is pretty nasty trap set on anyone who doesn't double check the status of the backup, before doing something like factory reset.

问:
Last ditch recovery for soft-bricked Galaxy Tab 10.1 possible?
Looking for some "heroic measures" advice here.

Some weeks ago, my Galaxy Tab2 10.1 (GT-P5113; Wifi only) suddenly threw itself into a bootloop frenzy that I have so far been unable to recover from.  Here are the facts, symptoms, and the measures I've attempted already:

running stock ROM 4.2.2; no root

there had been no recent update: when the bootlooping began, the tablet had been on all night but suddenly froze when I started to use it and began bootlooping

automatic app updates had been disabled, so I don't think any apps had updated recently

device reboots all the way into Android, but freezes and reboots within 30 seconds of achieving the Home Screen

booting into "safe mode" still results in bootloop

changing system variables do not persist between boots (e.g. enabling USB debugging; changing system volume; turning Wifi on/off)

entering recovery always includes message "Installing system update... NO COMMAND" with Andi lying down and exclamation mark symbol

"wipe data/factory reset" appears successful, but system reboots to previous state (NOT factory reset)

"wipe cache partition" terminates in "Error!" message with Andi and exclamation mark then reboots into the loop

I'm able to start into Odin mode and stock Android recovery, but am UNABLE to make any changes to the system in those modes:

attempting to flash TWRP or CWMR using ODIN or HEIMDALL appears successful, but upon restarting into recovery the stock Android recovery <3e> is there with the "no command" error

using either HEIMDALL or ODIN, trying to flash downloaded stock ROM appears successful for cache.img; SBL1.bin; recovery.img; but fails about halfway into system.img.  Same behaviour whether or not PIT repartition is selected.  Reboot shows no change.

Using Kies:  Kies just searches for the devices and typically fails, or takes so long the tablet is already rebooting by the time it briefly connects

trying to install the stock ROM from SD card fails (no useful information provided by the system)

dabbled a little with creating a bootable SD card, but the tablet just seems to ignore it

have tried mounting the internal storage to investigate the disk's health, but not even sure if this is possible?  Ubuntu 16.04 is "unable to mount MTP" and Windows 10 Explorer just doesn't show anything there.

I suspect a physical corruption of the internal storage, but with apparently no means to mount the drive, flash the recovery, flash the system, wipe the data and/or cache, I'm pretty much out of ideas.  Maybe the internal storage has become "read only" or has corrupt sectors?  Is this even possible?

As far as I'm concerned the device is basically bricked, so I'm willing to try any riskier ideas to kick-start this guy back into life...

(Yes, I understand this is an old device.  I like the big screen!)

Thanks,
Matt

Remounting a part of external SD card
Context: I've now spent more than 6 hours reading all articles / possible solutions I can find about the ".nomedia" file bug of Android 4+. See bug report here or also here or possible solution here. In short : for users with more than 10k media files on their microSD card (i have a 128 gb µSD!), the phone will be very hot at boot during 20 minutes / overheat / high cpu usage / fast battery drain ! Reason : Android 4+ doesn't care correctly about the ".nomedia" file like it did in Android 2.3, and the media scanner tries to browse all the files!

I'm looking for a workaround for this problem. Question :

Is it possible to remount a specific folder myfolder of my external SD card to /mypersonalfolder/ and hide it from /mnt/extSDcard/myfolder .

Can't change lock screen to a non-password option
This is on a Galaxy Note 3.

On Kitkat, in order to access work email we had to install MobileIron, which is a horrible suite of supposedly secure apps. As part of the installation I had to define MobileIron as administrator, and also to encrypt the phone. At that point I used a PIN lock on the lock screen.

Recently the Lollipop update became available. To install Lollipop I first had to decrypt the phone. During decryption it asked me to define a high-security password (alphanumeric, not PIN).

After decryption it no longer let me change the lock screen back to PIN (all the other options are grayed out, saying that the option was disabled by administrator, encryption policy or credential storage).

I tried encrypting it again, it didn't help.

I decrypted it back.

I removed MobileIron from the administrator list, and then also uninstalled all of the apps in the suite.

I installed some more updates following the Lollipop upgrade.

I restarted the phone after each step.

Nothing seems to help, all options but the password are still grayed out. What can it be?

Lost data after SIM card change on Samsung Galaxy J5
I changed my mobile operator and needed to use a new SIM card, so I turned off my Samsung Galaxy J5, replaced the old card with the new one and restarted the phone. After rebooting I noticed that all my messages and photos were gone. Unfortunately, when I put the old card again, the data was still lost.

I have  a couple of questions. Firstly, why was the data lost? Is that some kind of security mechanism to reset the phone when a new SIM card is used? Can it be configured in the settings? I didn't recall having similar problems before on other android smartphones.

Secondly, was the data really erased or is it possible that the photos are still somewhere on the phone, but due to the cards swap I can't see them? I checked all the folders on my phone after plugging it to my laptop, and the photos seem to be really gone, but I want to make sure before trying to use any recovery software.

And the last question - if the data was really lost, is it possible to recover it with unrooted phone? It seems that I can't force my phone to connect with USB mass storage mode, so using apps like Recuva is not possible. All the other Android specific apps that I found required the phone to be rooted. Are there any alternatives?

Stop Motion Video creation using external camera
my son is very interested in Lego stop-motion video creation.  There are myriad apps for stop motion capture on the Android platform, but using a device's internal camera isn't too easy, since you can't get a big phone or tablet into the correct position for the desired shots.

I have a USB webcam and a USB OTG cable.  Is there any way to use the external webcam as the image source for any of these stop-motion apps?

The idea setup would be to make the USB camera the default image source for any existing app.  Then he could directly capture into a simple, easy-to-use stop motion app instead of taking pictures first and inserting them frame-by-frame into the app later.

I have the following Android devices available, which can be used for this purpose:

Galaxy S2 (Sprint) android 4.x?

Galaxy S2 (AT&T) android 2.2

Alcatel onetouch Fierce XL - android 5.5

Hotspot: how to allow only vetted devices on Android Marshmallow

Issue

I recently updated to a phone that could use Android Marshmallow.

I was setting up the mobile hotspot, and I could not find the option to set the hotspot so that "only allowed devices can connect".

This was an option that I used to be able to do with my old phone, which was Android version 5.0.1.  (I think that's Lollipop, right?  I cannot keep up.)

I also changed phones & services.  I suspect it's the OS, but here is the comparison of the two phones' details, for completeness.

Before (where I could set the "only allowed devices can connect" option):

Samsung Galaxy S4 (model #SCH-I545)

Verizon wireless service

Android version:  5.0.1

Baseband version: I545VRUGOF1

Kernel version: 3.4.0

Build #: LRX22C.I545VRUGOF1

Hardware version: I545.06

Configuration version: J12.SAM.SCHI545.0

Now (where I cannot set the "only allowed devices can connect" option):

Nexus 5X

(Google) Project Fi service

Android version: 6.0.1

Baseband version: M8994F-2.6.32.1.13

Kernel version: 3.10.73-gf215204

Build #: MTC19Z

Hardware version: ?? (Cannot find it)

Configuration version: ?? (Cannot find it)

Function

Using the "only allowed devices" flag made my phone's hotspot hidden to others, so that only my validated machines can connect.  In this way, I didn't have to worry about any other machines logging on and bogging down my phone's puny hotspot (as well as any security concerns).

So, IMHO, this is a fairly powerful feature.  I use the hotspot often, and it's always within a population dense area (e.g., a train or bus).  If this is something that was stripped from the OS, what is the best way to let Google know that this is an important feature?

A second after somebody texts me again and I am to unlock it (connect the dots) again... and again and again and again...

Is there a way to configure screen standby and lock timeouts separately? Can I prevent the phone from locking itself too quickly without postponing the screen standby and without disabling the screen lock completely?


问:
Undo Location Services consent
I wanted to see whether WiFi-assisted GPS gave me better results indoors than GPS alone, so I went to Settings > Location > Mode and selected "High accuracy" instead of "Device only".

This prompted me to turn on Location Services and give Google access to my location at all times, which I don't really want to do long-term, but I allowed it to see what happened.

My GPS was no better, so I set my phone back to "Device only" mode. However, a couple of things have changed now which makes me suspicious that Google still thinks it has my permission to use Location Services to get my position:

If I select "High accuracy" again, I do not get another permission request.

If I turn Location off completely and back on again, it defaults to "High accuracy".

The Location icon is permanently in my status bar; it used to go away when not using e.g. Maps.

How can I rescind the permission I gave for Location Services to track my position, and get back to the state my phone was before?

Edit: I have a Moto X Play, stock ROM (pretty much vanilla Android 6.0.1).

How to double tap to open video feature of camera app?
I have a clip-on that I sometimes carry my phone in.  When clipped in, it is not possible to interact with the screen. However, I still have access to the buttons on the side, so the double-tap to open the camera is a very useful feature and the volume buttons (either one) can then be used to take one picture or pressing both simultaneously captures a burst.  However, what I would really like to do is to record video, not a still image.  How can I make the double-tap switch to camera in video mode?  I can't access my screen, so I can't swipe to select it, so I need the double-tap to go directly there.

I have a Nexus 6P, not rooted, Android 6.0.1.

Android to Android Files Sync over LAN

System and Play Store updates doesn't work on Android 4.4.2
I'm using a cloudfone excite 401dx with Android 4.4.2.

System update says "battery too low to install system update, connect charger to continue", but my battery is full. When I use the factory reset, the system update keep saying of my issue (battery too low to install system updates, connect charger to continue).

Still my Play Store won't update because of that issue, and I can't download any of games on my Android.


问:
Uninstalled app coming up in update list in play store
I uninstalled an app using a long tap shortcut that comes on One plus two mainscreen, which I guess is also the time when there is an update waiting for this app because the next time I opened the Play Store, an update shows up for the app. When trying to update and then uninstall (this time from Play Store), it still keeps showing up in Updates list and the whole things repeat.

The app is Swiftkey Keyboard, if that helps. Any recommendations on permanently removing the app would be helpful. Android v6.0.1, OS: OxygenOS v3.0.2

I tried Settings > Apps and there is no uninstall option, instead there is a disable option next to force stop. In play store, there is update option which doesn't help as I stated earlier.

I doubt if it is a system app, because I voluntarily installed it (from Google Play Store as I remember; I enabled installation from unknown sources only after the release of Pokemon go, I am not aware of any other possible ways of side-loading)

The app doesn't show up in Device Administrators (there's only Android Device Manager and another paid app visible in device administrators)

I disabled it, it stopped showing up in updates, keyboard menu and elsewhere, but it still is taking up that internal storage as shown in Settings > Apps.

问:
selinux denies busybox although selinux is set to permissive?
Device-info:

Phone: Sony Xperia Z1

Model number: C6903

Android version: 5.1.1

Build Number: 14.6.A.1.236

Rooted, BusyBox and Terminal Emulator installed (Play Store Version!!!)

I have formatted an SD-Card to an ext4-filesystem and put another Linux on it.
After mounting the filesystem and files without problems I want to execute:

chroot /data/local/mnt /bin/bash

with /data/local/mnt is the Linux root-folder. Execute the line above leads to the message:

chroot: can't execute '/bin/bash': Permission denied

I have checked the permission of /bin/bash and also of /data/local/mnt and remounted nearly every path which are related to that folder with exec and rw permission. So maybe you know some special rights-associated files or folders I forgot, but I think the problem is something else...

After readed that some of the Linux-on-Android project-users had some trouble with executing the init.sh because of selinux I set it to permissive:

root@C6903:/ # setenforce 0 and checked it:

```<code>root@C6903:/ # getenforce
Permissive
</code>```

(Of course) chroot does not work. So I checked the message buffer of the kernel for selinux-avc-deny-messages and BINGO:

```<code>root@C6903:/ # dmesg | grep denied
...
<36>[58575.652383] type=1400 audit(1470337082.042:10188): avc: denied { read } for pid=18553 comm="busybox" name="mmcblk0p23" dev="tmpfs" ino=9821 scontext=u:r:ric:s0 tcontext=u:object_r:block_device:s0 tclass=blk_file op_res=0 ppid=4602 pcomm="ric" tgid=4602 tgcomm="ric"
<36>[58575.653740] type=1400 audit(1470337082.042:10189): avc: denied { open } for pid=18553 comm="busybox" name="mmcblk0p23" dev="tmpfs" ino=9821 scontext=u:r:ric:s0 tcontext=u:object_r:block_device:s0 tclass=blk_file op_res=0 ppid=4602 pcomm="ric" tgid=4602 tgcomm="ric"
<36>[58575.655002] type=1400 audit(1470337082.042:10190): avc: denied { ioctl } for pid=18553 comm="busybox" path="/dev/block/mmcblk0p23" dev="tmpfs" ino=9821 scontext=u:r:ric:s0 tcontext=u:object_r:block_device:s0 tclass=blk_file op_res=0 ppid=4602 pcomm="ric" tgid=4602 tgcomm="ric"
</code>```

These are just 3. You can have some more if you want! So 1. QUESTION:

Why does selinux denies something when getenforce returns Permissive???

But I thought first that could be fixed anyway by allowing all these denied permissions with:

supolicy --live "allow source_class target_class permission_class permission"

FOR EXAMPLE:

root@C6903:/ # supolicy --live "allow ric rootfs file execute_no_trans" which returns:

```<code>Patching policy ...
-allow:ric:rootfs:file:execute_no_trans=ok
- Success
</code>```

Well (of course) it did not work AND I get a denied message for the exact same case for a bunch of cases. So 2. QUESTION:

Why does allowing policies not change policies to be allowed???

(Of course) I am not 100% sure if the denial of executing chroot is related to selinux and it would be very easy to find it out if I could just set it to permissive.... So 3. QUESTION:

How to solve this problem?

In Graeme Hill's Dev Blog article Compiling a permissive Android kernel he says:

There is a command called setenforce which toggles modes, and there are some apps on the Google Play store which do the same thing, but none of them will work until we modify the kernel.

Question:

Is that related to every device with Android 5.X or differs from manufacturers?

问:
Only first part of long text messages received
When someone sends me a long text message, I'm only receiving the first part of the message instead of receiving multiple messages.  I am able to consistently reproduce the issue.  When I first brought this up with Verizon support, they had me clear the data for the Messaging application, and then I started receiving all parts of a message.  However, the problem has now come back.  Obviously, I cannot constantly clear the data for the Messaging app, and even doing so does not help the fact that I'm permanently losing the full payload of messages.

Has anyone else encountered this problem and found a permanent fix?  Is there a replacement SMS app that works properly?  I've encountered this problem in the past with Android 2.3.3 and now with 2.3.4, both on my LG VS910 4G phone.

Android Doze drops Wifi regardless of optimalization settings
My LG G3 with Android 6.0 uses the built in Doze mode to save some battery.

At the first setup, I set applications to ignore Doze mode (like chat apps, Gmail, Viber etc.). I also set the "app" called Wifi to make my Wifi enabled while in Doze mode. They worked okay, I get my messages even if my phone is in Doze mode.

Why? And how can I make my phone to use Wifi permanently? What changed after 1 year?

Android - Rename file via sideload?
In an effort to get a WiFi adapter working I was following instructions on replacing a file called 'linker' in system/bin. Before copying the new linker file you gave I renamed my old one to linker2 because I wanted to be able to revert if needed.

After I renamed linker to linker2 my phone said I didn't have root anymore and I couldn't rename the file back.

I restarted and now am encountering an error that prevents booting. I'm in Android System Recovery with options:

```<code>reboot system now
apply update from ADB
wipe data/factory reset
wipe cache partition
reboot to bootloader
power down view
recovery logs
apply update from sdcard
</code>```

If I select 'apply update via ADB' I can use ADB from my laptop, but seems the only thing I can do is sideload a file. Is it possible for me to sideload and execute a simple script to rename that file back to linker instead of linker2?

Help is greatly appreciated.

Nexus 6 on T-Mobile loses ability to send texts. Factory reset does not fix
What is wrong with my mom's nexus 6. She was running stock Google Nexus software and kept encountering a problem where her texts would not send. I think I fixed it once by deleting the cache of some system apps (dialer service, messenger service) and restarting the device,  but I can't even be sure of that. I also tried a different default texting app.

It happened again last night so I spent a couple hours unlocking the Bootloader, installing twrp, and installing Cyanogen mod. While it works really well with cyanogen mod, she complained that the problem occured again after about 12 hours.

Does anyone here have insight into the likely cause of this? I reflashed recovery, so the only thing that remains is the bootloader.

Is it something with android 6.0, bootloader, baseband, or maybe something on Tmobile's end?

Unable to Seek on Full Screen Videos in Chrome/Chrome Beta
So I have an odd issue that I haven't been able to find a fix for. When I'm watching a video in Chrome (or Chrome Beta), if I go full screen, whenever I try to seek to a different time in the video, the video does not load/freezes. I can watch the video not in full screen and seek through it just fine, as soon as you go full screen (in portrait or landscape) seeking does not work.

However, this issue does not occur in the regular Internet browser. It also only occurs with a certain type of player, for instance, Vimeo does not have this issue. This issue used to only occur in Chrome Beta, but now it's occurring in both Chrome versions on Android.

I've tried uninstalling and reinstalling both versions of the app, as well as clearing cache/data for both versions of the app and neither has resolved it.

The device I'm using is a Galaxy S7 Edge on 6.0.1 (T-MO Variant)

Any help would be greatly appreciated.

问:
Adoptable Storage not using full SD card space since changing cards
I've got a strange issue going on with my adoptable storage setup. I have a SONY Xperia XA Ultra.

I initially got it working with a Sandisk 32GB Class 10 card. I adopted the entire card, and the Device storage went from "Total used of 16 GB" to "Total used of 48GB".

But then I had the bright idea to use one of my 64 GB cards, also Sandisk Class 10.

I repeated the process again, after reverting the 32GB back to portable of course, and adopted the entire 64GB card.

This time however only 16GB of the card was adopted, with the rest of the card basically lost. I couldn't see or access the rest of the card. Even with the Freespace app that part of the card just didn't exist.

So I reverted that and tried to adopt just 32GB, thinking maybe there is a limit to how much can be adopted. Same problem, only 16GB was adopted.

So I gave up, reverted that and went back to the 32GB card and adopted the whole card again. Only 16GB was adopted.

I tried 2 other cards a 64 & a 32, same problem.

And yes, I did migrate data and reboot each time. I even did a software repair before my last attempt.

Does anyone know how I can fix this?

When WhatsApp takes backup on Google Drive?
I am aware that Local back up is done by WhatsApp daily at 2 AM, from the official FAQ of WhatsApp. Below is the relevant quote:

Local backups will run automatically every day at 2am and save your
  database in a file on the phone itself.

But if I opted for Google Drive back up and selected the Frequency as Daily, then there is no clear time mentioned in the official WhatsApp/Google Drive info pages.

Same question can be extended for other Back up frequencies. For example  if Monthly, then which date of Month back up will be taken or if frequency is Weekly, then which day of the week back up will be taken to Google Drive.

My Question: Is there a way to know when/at what time WhatsApp takes Back up to Google Drive(and not a local backup, its already known, at 2AM Daily) for each of daily/weekly/monthly option?

Check and fix "formatted as internal" / encrypted SD Card i/o errors
Unfortunately I seem to have a problem with my filesystem on my as internal storage formatted SD card.
My problem is kind of related to this thread so I think it is worth mentioning here.

When I was restarting my device today I got the error that my SD card is corrupted. With a little bit of putting it in and out of the slot I eventually managed it to work again. Still the SD card is very slow and seems to have a corrupted file system. I managed to backup most of my data via adb pull but for some of the files I got an i/o error. I tried to run fsck as described in the other thread, but I cannot find any mount point of the SD card. I tried to umount every device in /dev/block/vold/ but it always gives me Invalid argument error.

Of course I cannot try to fix it outside of my running device, as it is encrypted.

Is an as internal storage SD card behaving differently? Where is the mount point for this.
