first, sorry for my english :)

i try to install a user app (installed in /data/app/) as system app on my new galaxy s7 : - Android 6.0.1 - Rooted - factory ROM

I follow many tutorials :

http://www.addictivetips.com/mobile/how-to-install-any-app-as-system-app-on-android/ http://www.androidauthority.com/install-user-app-as-system-app-how-to-93522/

After reboot, my application is in the the folder /system/app but i can't launch it: it crash when i launch apk directly, even if permission are correctly set.

With another smartphone (samsung s4 rooted with cyanogenmod and SE Permisive), the copy paste technique work well.

Someone knows why i can't launch it ?

Thanks a lot

  • First tip: for third party apps that are installed as system apps, the /system/priv-app path is to be preferred in comparison to /system/app.

    Heh... couldn't be that simple. Ok, second tip: via a terminal emulator, run u:object_r:system_file:s0 path_of_your_app.apk as root and reboot. This changes the context of your app, making SELinux believe it's a genuine system app, so apply this procedure only if you're absolutely sure that your app is not a malware.

  • No problem. You also gave me the clue I needed to improve my flashable ZIP generator.
