Android SDK gets NotRegistered error from GCM after a few hours

Question

The problem

I am writing and Android SDK which should receive GCM push messages from the SDK server side. After a few hours of successful push message sending, the GCM server returns an NotRegistered error:

{
    "multicast_id":6205350692941230304,
    "success":0,
    "failure":1,
    "canonical_ids":0,
    "results":
    [
        {
            "error":"NotRegistered"
        }
    ]
}

The registrationId at the client has not changed, and the server side is updated with that token.

How can I fix the registrationId problem? Is having two listeners - one in the SDK, one in the app - a problem?

Architecture

My Android SDK registers a GCM regId upon initialization, and sends that id to the server supporting the SDK.

The embracing app might (and usually do) register a GCM regId of its own. The other regId is probably sent to the embracing app's server.

The senderId of the SDK and app are different.

Implementation

Manifest

<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> ...

    <receiver
        android:name="com.xxxx.xxxxx.xxxxx"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        </intent-filter>
    </receiver>

Registration code

protected String doInBackground(Void... params) {
    String msg = "";
    try {
        if (gcm == null) {
            gcm = GoogleCloudMessaging.getInstance(mContext);
        }
        regid = gcm.register(SENDER_ID);
        msg = "Device registered, registration ID=" + regid;
        storeRegistrationId(mContext, regid);
        listener.onGCMRegisterFinish(regid);
    } 
    catch (IOException ex) 
    {
        msg = "Error :" + ex.getMessage();
    }
    return msg;
}

This code gets the regId from the GCM Server and send it to our backend server. It is executed at the SDK initialization, and the regId is sent every time the app returns from background.

Notes

• unregister() is not called, neither from server or client side
• I am raising a toast with the registration id every once in a while, so I can verify it is the same between the client and the server:

Client side

Server side

Answer 1

Add Category with your package name to the intent-filter

  <receiver
        android:name=".xxxxx"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <!-- Receives the actual messages. -->
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.xxxx" />
        </intent-filter>
    </receiver>

Answer 2

The registration ID´s generation includes not only the device but also the app and the sender ID. If I understood your architecture correctly you want to implement a GCM-client-library (your SDK) enabling your app to use GCM through your library? If that´s true make sure that you only register once

The senderId of the SDK and app are different

I assume this is the problem, you have to register each app with a sender id (e.g. XYZ) and use the SAME sender id at the server to send the notification. It is not possible to use ABC as sender id to send notifications to a device registered for sender id XYZ
