title: GCM: why my application crash in GCMRegistrar.checkDevice(this);
body: <p>I have a simple application with a few lines because I am trying to figure out why my real application crashes in GCMRegistrar.checkDevice(this) (if I delete it my application doesn't crash). Can anyone help? :(
  :</p>
  
  <pre><code>public class DemoActivity extends Activity {
  private String TAG = "** pushAndroidActivity **";
  private TextView mDisplay;
      @Override
      public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         GCMRegistrar.checkDevice(this);
         GCMRegistrar.checkManifest(this);
          setContentView(R.layout.main);
          mDisplay = (TextView) findViewById(R.id.display);
          mDisplay.setText("ciao");
  }
