Answer 1

You should first look into the Android native PackageInstaller. I would recommendating you to update all the code you use.

Next step is to inspect PackageInstaller which is an normal class. You will find that uninstall function there. The bad news is that this needs Manifest.permission.DELETE_PACKAGES permission and its only granted to system apps. This means that this is not available directly to other developers. But we can access it using device owner permission.

This requires:

• Android 6.0 or newer
• Device owner permission to uninstall the package

Generally the DELETE_PACKAGES permission says:

Allows an application to delete packages.

Not for use by third-party applications.

Once your app gets the device owner permission, you can uninstall an package like this:

String appPackage = "com.your.app.package";
Intent intent = new Intent(getApplicationContext(), 
getApplicationContext().getClass()); //getActivity() is undefined!
PendingIntent sender = PendingIntent.getActivity(getActivity(), 0, intent, 0);
PackageInstaller mPackageInstaller = 
getActivity().getPackageManager().getPackageInstaller();
mPackageInstaller.uninstall(appPackage, sender.getIntentSender());
