Android - uninstall other system app as system app
My app is running as a system app on a custom AOSP image. I am able to uninstall/install other APKs that I'm downloading from my backend. However, I cannot uninstall other system apps (which is a hard requirement for my purpose). My current mechanism is to use the deletePackage mechanism from the Android package manager via reflection:
val cPackageManager = Class.forName("android.content.pm.PackageManager")
cPackageDeleteObserver = Class.forName("android.content.pm.IPackageDeleteObserver")
deletePackage = cPackageManager.getMethod("deletePackage", String::class.java, cPackageDeleteObserver, Integer.TYPE)
deletePackage!!.invoke(context.packageManager, packageName, deleteObserver, DELETE_ALL_USERS)
Does anybody know how to achieve what I'm trying to do?

Don't you need to be a rooted device to uninstall
System apps, or have you found a way to do this without any rooting?You must
remountthe system, since you run SELinux, to be able to rearrange the locked files in the system.
3.You can run this code in your app instead
try{
Process su = Runtime.getRuntime().exec("su");
DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());
outputStream.writeBytes("pm uninstall com.package.name");
outputStream.flush();
outputStream.writeBytes("exitn");
outputStream.flush();
su.waitFor();
}catch(IOException e){
throw new Exception(e);
}catch(InterruptedException e){
throw new Exception(e);
}
if pm uninstall doesn't work, use the rm -rf path/deletefolder then reboot the system

the device in question is not rooted, so this will probably not work. My app has system privileges though, but I guess it won't be able without remounting the system as you said.

If you still have time to develop then try this here,mount -o rw,remount /system, Method 2. By terminal you should runt the code above. Try this locally before further development --> android.stackexchange.com/questions/110927/…
