Force Android application close and restart

As I recall, there is no way to do this, but you can finish the activity you are doing and start again, basically this FLAG cleans the stacked activities and starts the one you want.

I would advise you to take a look at the FLAGS documentation and can help you with any other questions: FLAGS

How to do:

Intent intent = new Intent(getActivity(), SuaActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
finish();
