adb uninstall failed

Question

I am writing some sample apps.
After I debug these apps, I don't see an uninstall button in my device's application management.
When I do adb uninstall, it always says Failure without any reason.
In DDMS I saw that my apk is stored in /data/app/com.k2g.leaveDemo-1.apk.
I am not sure what am I missing.
I always have to reset my device to get rid of these apps :(

Do I need to do sign something?
Do I need to do something in debug mode?
Or does it depend on the version?

I am using Samsung S2.

Answer 1

This worked for me:

This is the directory where all the APKs are stored:

cd /system/app

List them:

ls

Choose one to remove.

pm install -r <app_to_remove>.apk

Example:

$ pm install -r Google-Play-services.apk
        pkg: Google-Play-services.apk
Success

---

I noticed that I get failure if the application I'm trying to remove is running, so kill it first.

Also, I noticed you might have to run (on a rooted device):

$ su
# mount -o remount +rw /

I had a instance of an emulator running and a device connected.

When I ran command `adb -d uninstall PACKAGE_NAME', I got an error 'DELETE_FAILED_INTERNAL_ERROR' but when I killed the Emulator instance, I got a 'success' in un-installation process.

I had a failure when using adb shell uninstall com.package.app/

removed / (so adb shell uninstall com.package.app) and it works

Answer 5

Yes, mobile device management would bring its own problems, but i bet 'Failure' is a dos2unix problem. On my Linux machines, adb is appending a DOS newline which causes 'Failure' because uninstall thinks the CR character is part of the package name. Also remove '-1.apk' from the end of the package-1.apk filename.

adb root
adb shell
pm list packages
pm uninstall com.android.chrome

In my case, i have a phone that is in permanent 'Safe mode' so only apps under /system/app/ have a chance of running. So i install them to get the .apk files copied off, then uninstall in bulk and copy to /system/app/, wipe the /cache and reboot. Now i have more apps running even though in safe mdoe.

# adb root
# pm list packages -3 > /root/bulkuninstall.txt
# vi /root/bulkuninstall.txt  and check ^M characters at end of each line.   
   If ^M, then must run dos2unix /root/bulkuninstall.txt.  
   Remove '-1.apk' using vi search and replace:  
        :%s/-1\.apk//g 
   Or sed...

# cp /data/app/* /storage/sdcard1/APKs/
# for f in `cat /root/bulkuninstall.txt`; do echo $f; pm uninstall $f; done;
# 
# echo Now remount system and copy the APK files to /system/app/
# mount | grep system
# mount -o remount,rw /dev/block/(use block device from previous step)  /system 
# cp /storage/sdcard1/APKs/* /system/app/
# reboot

wipe cache power on.

Maybe you're trying to uninstall an app that is a phone administrator.

To be able to uninstall it, go to Seetings > Security > Phone Administrators. If the app is listed, uncheck it and confirm the operation.

After that, you should be able to uninstall it using the App settings area or adb.
