Google Cloud Messaging Registration TIMEOUT

Question

I've chosen Google Cloud Messaging for my application, which is so far working perfectly on Google APIs 17,18, 19 & 21. However, on Google APIs 16, I get a TIMEOUT at registration level. Has anyone faced this before ? I am using an AsyncTask as recommended by Google.

My code:

private class PrefetchData extends AsyncTask<Void, Void, Void> {

@Override
protected void onPreExecute() {
    super.onPreExecute();
    // before making http calls         
}

@Override
protected Void doInBackground(Void... arg0) {

try{

    // ...

    // register device to Google Cloud Messaging if not already done
    if(gcmDeviceRegID.equals("")){
        gcm = GoogleCloudMessaging.getInstance(getApplicationContext());
        gcmDeviceRegID = gcm.register(PROJECT_NUMBER);
    }

}

catch( Exception e ){
    e.printStackTrace();
    return null;
}

return null;

}

//...

The log:

W/InstanceID/Rpc(887): Found 10016

As you understand, SplashScreenActivity.java:104 is this line:

gcmDeviceRegID = gcm.register(PROJECT_NUMBER);

Any idea how to solve this? Thanks!

Answer 1

As per Arthur Thompson's comment, this is being solved by using the new recommended way to register to GCM (starting from 2015, June 28):

InstanceID instanceID = InstanceID.getInstance(getApplicationContext());
gcmDeviceRegID = instanceID.getToken(PROJECT_NUMBER,GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);

instead of

gcm = GoogleCloudMessaging.getInstance(getApplicationContext());
gcmDeviceRegID = gcm.register(PROJECT_NUMBER);
