  <p>Trying to get GCM up and running but my device is sending a registration request, but getting no response back from the GCM server.  Below I included my manifest and GCMIntentService definition, and my call to register with the GCM server.  I've been staring at it so long I might be missing something obvious, if so I apologize.</p>
  
  <p>All ideas welcome!</p>
  
  <p><strong>Here is my manifest:</strong></p>
  
  <pre><code>&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="PACKAGE"
      android:versionCode="1"
      android:versionName="1.0" &gt;
  
      &lt;uses-sdk
          android:minSdkVersion="8"
          android:targetSdkVersion="15" /&gt;
  
      &lt;permission android:name="PACKAGE.permission.C2D_MESSAGE" android:protectionLevel="signature" /&gt;
      &lt;uses-permission android:name="PACKAGE.permission.C2D_MESSAGE" /&gt; 
      &lt;uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /&gt;
      &lt;uses-permission android:name="android.permission.WAKE_LOCK" /&gt;
      &lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  
      &lt;application
          android:icon="@drawable/ic_launcher"
          android:label="@string/app_name"
          android:theme="@style/AppTheme" &gt;
  
          &lt;service android:name=".GCMIntentService" 
              android:enabled="true"/&gt;
  
          &lt;receiver
              android:name="com.google.android.gcm.GCMBroadcastReceiver"
              android:permission="com.google.android.c2dm.permission.SEND" &gt;
              &lt;intent-filter&gt;
                  &lt;action android:name="com.google.android.c2dm.intent.RECEIVE" /&gt;
                  &lt;action android:name="com.google.android.c2dm.intent.REGISTRATION" /&gt;
  
                  &lt;category android:name="PACKAGE.GCMIntentService" /&gt;
              &lt;/intent-filter&gt;
          &lt;/receiver&gt;
  
  
          &lt;activity
              android:name=".MainActivity"
              android:label="@string/title_activity_main" &gt;
              &lt;intent-filter&gt;
                  &lt;action android:name="android.intent.action.MAIN" /&gt;
  
                  &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
              &lt;/intent-filter&gt;
          &lt;/activity&gt;
      &lt;/application&gt;
  
  &lt;/manifest&gt;
  </code></pre>
  
  <p><strong>Here is my GCMIntentService to handle the return from GCM:</strong></p>
  
  <pre><code>import com.google.android.gcm.GCMBaseIntentService;
  import android.content.Context;
  import android.content.Intent;
  import android.util.Log;
  
  
  public class GCMIntentService extends GCMBaseIntentService {
      public static String TAG = "GCMIntentService";
  
      public GCMIntentService(String senderId) {
          super(senderId);
          Log.d("GCMIntentService", senderId);
      }
  
      @Override
      protected void onError(Context arg0, String arg1) {
          Log.d("onError", arg1);
      }
  
      @Override
      protected boolean onRecoverableError(Context context, String errorId){
          Log.d("onRecoverableError", errorId);
          return false;
      }
  
      @Override
      protected void onMessage(Context arg0, Intent arg1) {
          Log.d("onMessage", String.valueOf(arg1));
      }
  
      @Override
      protected void onRegistered(Context arg0, String arg1) {
          Log.d("onRegistered", arg1);
      }
  
      @Override
      protected void onUnregistered(Context arg0, String arg1) {
          Log.d("onUnregistered", arg1);
      }
  }
  </code></pre>
  
  <p><strong>I attempt to register with the following in the onCreate method of my main class:</strong></p>
  
  <pre><code>GCMRegistrar.checkDevice(this);
  GCMRegistrar.checkManifest(this);
  
  final String regId = GCMRegistrar.getRegistrationId(this);
  if (regId.equals("")) {
      GCMRegistrar.register(this, SENDER_ID);
  } else {
      Log.d(TAG, "Already registered");
  }

  <p><strong><em>UPDATE</em></strong>
  I have tried Raz's suggestion and I got the following error:</p>
