Google Cloud Messaging register AUTHENTICATION_FAILED

Question

I want to try Google Cloud Messaging (GCM) service, and I am faced with a problem at the beginning.

I get an error AUTHENTICATION_FAILED while trying t

Answer 1

So it looks like the solution to avoid this problem is to fall back to the old deprecated GCM client library in case the AUTHENTICATION_FAILED error happens on FROYO and GINGERBREAD.

Here is a simple code snippet of how I upgraded the new Gcm client to fallback to use the old client:

@Override
protected void onPostExecute(Integer resultCode) {

    if(resultCode == EXCEPTION_THROWED) {

        //Android 2.2 gmc bug http://stackoverflow.com/questions/19269607/google-cloud-messaging-register-authentication-failed

        //fall back to old deprecated GCM client library

        GCMRegistrar.checkDevice(StartActivity.this);
        GCMRegistrar.checkManifest(StartActivity.this);
        final String registrationId = GCMRegistrar.getRegistrationId(StartActivity.this);
        if (registrationId.equals("")) {
            GCMRegistrar.register(StartActivity.this, SENDER_ID);
        }

        //Toast.makeText(context, "Orders and menus won't be sync with other devices since GoogleCloudMessaging is not working correctly on this device. Please notify the developer.", Toast.LENGTH_LONG).show();

    }

}

You can find the old deprecated GCM Client helpher here: http://developer.android.com/google/gcm/helper.html

You can find the code of the GCM client on your computer on the path: ANDROID_SDK_ROOT/extras/google/gcm-client (given you've downloaded this extra using the Android SDK Manager).

I put the old gcm client in a new package named com.google.android.gcm.deprecated to try to remember myself to not use this for other stuff.
