I can't for the life of me figure out how to have an activity be refreshed after pressing the back button. I currently have activity A that fires an intent to goto B and while on act B if you press back I want to go back to act A but have it refresh itself. I can use this intent to refresh the activity currently:
Intent refresh = new Intent(this, Favorites.class);
startActivity(refresh);
this.finish();
But I can't figure out how to properly use the onResume() function to refresh my act A after going back to it.
