How to receive messages using the new Google Cloud Messaging Api for Android?

I have found tons of tutorials explaining Google Cloud Messaging but all seem deprecated with the new Google Cloud Messaging Api
In fact I cannot get a valid registration id using the deprecated GcmRegistrar class!
While using the new api I can get a valid registration id and use that to perform successful requests from my server to google.

I am lost as to how will I implement a Receiver in the Android App that will enable me to actually use the received messages.
I guess GCMBaseIntentService and all relevant code is now deprecated and implemented in another way

The google docs are referring to this:

<receiver android:name=".MyReceiver" android:exported="true"
 android:permission="com.google.android.c2dm.permission.SEND" >
 <intent-filter>
    <action android:name="com.google.android.c2dm.intent.RECEIVE" />
    <category android:name="YOUR_PACKAGE_NAME" />
 </intent-filter>
</receiver>

So how could I implement this MyReceiver?

The answer was much simpler than I thought.
You no longer need gcm.jar nor gcm-server.jar.
No need for a special service like GCMIntentService
No need for the receiver to handle this action: com.google.android.c2dm.intent.REGISTRATION

Actually a developer now needs to implement his own BroadcastReceiver which is as simple as that:
in Scala

class MyReceiver extends BroadcastReceiver {
  def onReceive(context: Context, intent: Intent) {
    log log "we have received something!";
    val extraString = Option(intent.getStringExtra("json label here"));
    log log "the value of this json label is: " + extraString;
  }
}
