C2DMessaging.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";
public static final String REGISTRATION_ID="registrationid";

// package
static final String PREFERENCE = "wea.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);
    // TODO: if intent not found, notification on need to have GSF
}

/**
 * Unregister the application. New messages will be blocked by server.
 */
public static void unregister(Context context) {
    Intent regIntent = new Intent(REQUEST_UNREGISTRATION_INTENT);
    regIntent.setPackage(GSF_PACKAGE);
    regIntent.putExtra(EXTRA_APPLICATION_PENDING_INTENT, PendingIntent.getBroadcast(context,
            0, new Intent(), 0));
    context.startService(regIntent);
}

C2DMBroadcastReceiver.java

public class C2DMBroadcastReceiver extends BroadcastReceiver {

@Override
public final void onReceive(Context context, Intent intent) {
    // To keep things in one place.
    C2DMBaseReceiver.runIntentInService(context, intent);
    setResult(Activity.RESULT_OK, null /* data */, null /* extra */);        
}

}

Problem in your manifest file

you must write service and receiver tag within application tag

for example:

<application android:icon="@drawable/icon"
        android:label="@string/app_name">

<service
            android:name=".C2DMReceiver"
            android:enabled="true" />

<!--SAME FOR RECIEVER-->

</application>

One more thing..you are writing

<receiver
            android:name="com.google.android.c2dm.C2DMBroadcastReceiver"

is your folder structure is com/google/android/c2dm/ which contains C2DMBroadcastReceiver class?
