Thank you very much for helping me

A: Get rid of this block from the manifest...
    <receiver
        android:name=".NotifyMeActivity"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter >
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" >
            </action>

            <category android:name="com.notifyme" />
        </intent-filter>
    </receiver>

Then add the <intent-filter> from the above to your .C2DMReceiver entry...
    <receiver
        android:name=".C2DMReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter >
            <action android:name="com.google.android.c2dm.intent.RECEIVE" >
            </action>
            <category android:name="com.notifyme" />
        </intent-filter>
        <intent-filter >
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" >
            </action>
            <category android:name="com.notifyme" />
        </intent-filter>
    </receiver>
