title: where is com.google.android.gcm.GCMBaseIntentService?
body: <p>I'm following the tutorial on GCM here <a href="http://developer.android.com/guide/google/gcm/gs.html">http://developer.android.com/guide/google/gcm/gs.html</a></p>
  
  <p>At point 5 of <strong>Step 2</strong>, it says: </p>
  
  <blockquote>
    <p>Add the following intent service:
    service android:name=".GCMIntentService"</p>
  </blockquote>
  
  <p>This intent service will be called by the GCMBroadcastReceiver (which is is provided by GCM library), as shown in the next step. It must be a subclass of <code>com.google.android.gcm.GCMBaseIntentService</code>, must contain a public constructor, and should be named <code>my_app_package.GCMIntentService</code> (unless you use a subclass of <code>GCMBroadcastReceiver</code> that overrides the method used to name the service).</p>
  
  <p>However, I can't subclass <code>com.google.android.gcm.GCMBaseIntentService</code>, the import can't be resolved. How do I fix this?</p>
