Google cloud messaging unable to initialize receiver

Im following the tutorial here: http://developer.android.com/google/gcm/gs.html

I seem to have some problems registering my translator

I get the following error when starting the application right after registering the device and getting the registration ID

java.lang.RuntimeException: unable to instantiate receiver com.google.android.gcm.GCMBroadcastReceiver: java.lang.ClassNotFoundException: com.google.android.gcm.GCMBroadcastReceiver

Here is the full stackTrace:

My class is GCMBroadcastReceiver

 package pushNotification; import com.google.android.gms.gcm.GoogleCloudMessaging; import com.gotoohlala.OohlalaMain; import discoverMyCampus.RulesFragment; import android.app.Activity; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.support.v4.app.NotificationCompat; import android.util.Log; /** * Handling of GCM messages. */ public class GCMBroadcastReceiver extends BroadcastReceiver { static final String TAG = "GCMDemo"; public static final int NOTIFICATION_ID = 1; private NotificationManager mNotificationManager; NotificationCompat.Builder builder; Context ctx; @Override public void onReceive(Context context, Intent intent) { Log.d("SUCCESS SUCCESS", "ONRECEIVE HAS BEEN CALLED, WOOT WOOT!!"); GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context); Log.d("SUCCESS SUCCESS", "ONRECEIVE HAS BEEN CALLED, WOOT WOOT!!"); ctx = context; String messageType = gcm.getMessageType(intent); if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(messageType)) { sendNotification("Send error: " + intent.getExtras().toString()); } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(messageType)) { sendNotification("Deleted messages on server: " + intent.getExtras().toString()); } else { sendNotification("Received: " + intent.getExtras().toString()); } setResultCode(Activity.RESULT_OK); } // Put the GCM message into a notification and post it. private void sendNotification(String msg) { mNotificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE); PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, new Intent(ctx, RulesFragment.class), 0); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(ctx) .setContentTitle("GCM Notification") .setContentText(msg); mBuilder.setContentIntent(contentIntent); mNotificationManager.notify(NOTIFICATION_ID, mBuilder.getNotification()); } }

Any ideas as to why I cannot register the receiver? Thanks

The app is looking for com.google.android.gcm.GCMBroadcastReceiver , but your class is in another pushNotification.GCMBroadcastReceiver package.

And the package of your application is different from it - com.myAppName .

While your GCMBroadcastReceiver should not be in the same package as your application package, the category in the intent filter should be the application package.

You should change this:

  <intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <category android:name="pushNotification" /> </intent-filter>

For this:

  <intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <category android:name="com.myAppName" /> </intent-filter>

EDIT:

Depending on your manifest, you have additional errors:

You indicate the broadcast receiver twice. If you want to use your own receiver, you must remove this part:

  <receiver android:name="com.google.android.gcm.GCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" > <intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <action android:name="com.google.android.c2dm.intent.REGISTRATION" /> <category android:name="com.gotoohlala" /> </intent-filter> </receiver>

Another problem:

Remove this line:

 <uses-permission android:name="com.gotoohlala.gcm.permission.C2D_MESSAGE" />

Since you already have these lines (which are correct):

 <permission android:name="com.gotoohlala.permission.C2D_MESSAGE" android:protectionLevel="signature" /> <uses-permission android:name="com.gotoohlala.permission.C2D_MESSAGE" />
