I'm able to install own application into /system/app using adb shell commands. But how to uninstall it? Is there any commands to do it? My phone is rooted.

Manual uninstall using ADB :

During website downtime (like now) see crawled snapshot here:
https://web.archive.org/web/20180222063358/http://www.careace.net/2010/05/12/how-to-remove-android-apps-through-adb/

Programmatically:

    public static void deleteFromSystem (final String file)
    {
        try 
        {
            if (new File(file).exists())
            {
                String  path        = new File(file).getParent();
                Process process     = Runtime.getRuntime().exec("su");
                DataOutputStream os = new DataOutputStream(process.getOutputStream());
                os.writeBytes("mount -o rw,remount /system; \n");
                os.writeBytes("chmod 777 "      + path + "; \n");
                os.writeBytes("chmod 777 "      + file + "; \n");
                os.writeBytes("rm -r "          + file + "; \n");
                os.writeBytes("mount -o ro,remount /system; \n");
                os.writeBytes("reboot \n");
                os.flush();
                os.close();
                process.waitFor();
            }
        } 
        catch (Throwable e) {e.printStackTrace();}
    }

  • I tried your snippet in my application.The has been removed from home screen.But I have a problem after uninstalling app and then to reinstalling app it manages its sharedpreference state. I need the preferences need to clear. – Senthil Mg Jun 06 '13 at 06:41
  • This code gives the following IO Exception to me: Working Directory: null Environment: null Yes I used the correct app name. – Behnam Nov 26 '13 at 12:40
  • @ Campiador Have you root? – XXX Nov 26 '13 at 14:17
  • I think that in the past, it succeeded without restarting. is this the best way to uninstall system apps? – android developer Apr 29 '14 at 21:09

Assuming you have root access to device:

adb shell
su
mount -o rw,remount /system
rm -rf /system/app/myApp.apk
rm -rf /data/data/com.example.myapp
mount -o ro,remount /system
exit
exit

Im not sure if you have to do this on every device (may be it can be achieved just by root access on some devices ) but on htc desire you have to reboot to the recovery mode Then you can copy your apk to the sdcard and then using adb shell to the /system/app folder you should create a nandroid backup first
