title: Send string from service to activity
body: <p>I'm trying to send string from service to my main activity with broadcast.
  I have read in a few forums that there are 2 ways to use broadcast. One is to register the activity in the manifest and the second way is to do it on the activity, local. 
  I would like to know how I can use the second way. I have tried to do it but unfortunately I did not succeed.</p>
  
  <p>Please tell me what I'm doing wrong.</p>
  
  <p><strong>Service code</strong></p>
  
  <pre><code>   public class MyGcmListenerService extends GcmListenerService {
  
  private static final String TAG = "MyGcmListenerService";
  
  // [START receive_message]
  @Override
  public void onMessageReceived(String from, Bundle data) {
      String typemessage = data.getString("typemessage"); // typeMessage = 0 or 1 = lock or unlock
      String datamessage = data.getString("datamessage"); // dataMessage = time and message that says lock or unlock
  
      Log.d(TAG, "TypeMessage: " + typemessage);
      Log.d(TAG,"DataMesaage:"+ datamessage);
  
      Intent in = new Intent();
      in.putExtra("TYPE",typemessage);
      in.setAction("NOW");
      sendBroadcast(in);
