Google Play Services : Notify adapter of data change ?

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

    // YOUR CODE HERE
notifyDataSetChanged();
}

}

I added the call to notifyDataSetChanged() , where am I going wrong?

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) {

        // YOUR CODE HERE

    }
}

The challenge states the Adapter is named adapter. Since you're not inside the adapter, but calling it from another class, it needs to be adapter.notifyDataSetChanged();

Seth Kroger : Thanks for the prompt response. A lot of us are also stuck on an empty screen from Etsy and no moderator and mentor has reviewed that post. Could you please have a look at that too.

Much Appreciated.
