Answer 1

Would you be looking for the following flags to add to the Intent you start the other application with:

FLAG_ACTIVITY_CLEAR_TASK

Answer 2

Try adding this flags to your intent

Intent intent= getPackageManager().getLaunchIntentForPackage("com.package.address");

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
