What are the preconditions to get following behaviour:
- app can't be uninstalled NOR disabled
- app runs as system app
What I know so far:
- rooted phone => actually, not necessary if app is a system app
What I tried:
- install app under
/system/app=> this makes it uninstallable but it still is deactivateable - install app under
/system/app-priv=> does not change anything compared to installing it under/system/app - install app under
/system/app-priv/<app_name>=> this breaks the app
Ideas
- To correctly make an app an system app it must be signed as a system app? Could this be? Then I can move it to
/system/app-priv/<app_name>? Just a guess, but I think I've already read something like this when reading about something else... If this is true, how do I sign my app as system app? - am I wrong or missing something?
I'm open to alternate solutions, all I want is that my app can't be deinstalled nor disabled
