title: 2 GCM registrationId for same android application
body: <p>I have 2 GCM BroadcastReceivers in my application (One for an android library integrated in my application and one for my own application).
  Both of them are registered in the manifest and have the same category (Which is my application package name).</p>
  
  <p>Both have registration with register() function and both receives different valid registrationId's (because the senderId for both are different).</p>
  
  <p>My problem is that I have everything work fine (Both Recievers get the push notification) but after a couple of hours when trying to send a push from Server I encounter "NotRegistered" issue in my server (android library regId) and registrationId seems invalid all of a sudden.</p>
  
  <p>So my question is can I have 2 different GCM "Mechanism" in the same application with different senderId without a collision or some sort on GCM Servers ?</p>
