C2DMBroadcastReceiver onReceive not executing (for registration)

Im developing a C2DM Messaging application. In this case, I get the registration identifier im using classes C2DMBroadcastReceiver, C2DMBaseReceiverand C2DMMessaging. I will be C2DMReceiverin my package, which expands C2DMBaseReceiver.

Here is my code snippet

C2DMMessaging.java

package com.google.android.c2dm;

import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;

    public static String getRegistrationId(Context context) {

                PREFERENCE,
                Context.MODE_PRIVATE);

C2DMBroadcastReceiver.java

package com.google.android.c2dm;

import android.app.Activity;

public class C2DMBroadcastReceiver extends BroadcastReceiver {

        // To keep things in one place.
           Log.e("C2DM Broadcast receiver","onReceive");
        C2DMBaseReceiver.runIntentInService(context, intent);
        setResult(Activity.RESULT_OK, null /* data */, null /* extra */);        
    }

}

C2DMMessaging.java

public class C2DMessaging {
    public static final String EXTRA_SENDER = "sender";
    public static final String EXTRA_APPLICATION_PENDING_INTENT = "app";
    public static final String REQUEST_UNREGISTRATION_INTENT = "com.google.android.c2dm.intent.UNREGISTER";
    public static final String REQUEST_REGISTRATION_INTENT = "com.google.android.c2dm.intent.REGISTER";
    public static final String LAST_REGISTRATION_CHANGE = "last_registration_change";
    public static final String BACKOFF = "backoff";
    public static final String GSF_PACKAGE = "com.google.android.gsf";


    // package
    static final String PREFERENCE = "com.google.android.c2dm";

    private static final long DEFAULT_BACKOFF = 30000;

    /**
     * Initiate c2d messaging registration for the current application
     */
    public static void register(Context context,
            String senderId) {
        Intent registrationIntent = new Intent(REQUEST_REGISTRATION_INTENT);
        registrationIntent.setPackage(GSF_PACKAGE);
        registrationIntent.putExtra(EXTRA_APPLICATION_PENDING_INTENT,
                PendingIntent.getBroadcast(context, 0, new Intent(), 0));
        registrationIntent.putExtra(EXTRA_SENDER, senderId);
        context.startService(registrationIntent);
        Log.e("C2DM Services","Service Started");
   }
   ..........

}

Now my problem is:

I call Register from C2DMMessaging from my activity, passing context. The service is created in C2DMMessaging, after which im does not receive anything in C2DMBroadcastReceiver onReceive () .
