Answer 1

You can get the update time for your app and save it in a SharedPreference.

Also, you should just make your main activity the always run one.

//In your onCreate for your main activity/.
if(last_update_preference < current_update_time){
   Update last update preference to current update time.
   Run first activity. (Which will finish and bounce you back);
}

To get the current_update_time:
