Try changing:
<uses-permission android:name="com.maxap.lj3.gcm.permission.C2D_MESSAGE" android:protectionLevel="signature"/>
To
<permission android:name="com.maxap.lj3.gcm.permission.C2D_MESSAGE" android:protectionLevel="signature"/>
You were trying to use the com.maxap.lj3.gcm.permission.C2D_MESSAGE
permission, but in your manifest you didn't declare it properly. You need to use <permission>
not <uses-permission>
to declare them.
