Android Google Play Services Connecting to Play Services Notify an Adapter of Changed Data

I don't really Understand what I'm supposed to do here

I must be missing something that is being asked of me... but I really thought this method specifically did what is being asked of me.

MainActivity.java
// This is an excerpt from the full file.
protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
    if (requestCode == REQUEST_CODE && responseCode == RESULT_OK) {
          notifyDataSetChanged();     

      // YOUR CODE HERE

    }
}

You do want to use notifyDataSetChanged(), but remember it's a method for an Adapter and you are in an Activity which doesn't have that method. You'll need to call that method on the adapter instead of just calling it like it's part of the activity.

Ah, thanks dawg, that makes a lot of sense. TBH this video section feels like its going unusually fast so it doesnt feel like its sticking quite as well. T
