GCM getToken() sends java.io.IOException: TIMEOUT

Question

I am implementing push notifications, but I receive TIMEOUT exception when calling getToken.

I've set the app for GCM here and SENDER_ID is exactly the one provided. Also, Server API key was saved on the backend part.

Is there a limited number of getToken requests? I had no problems at first several attempts when testing push notifications.

new AsyncTask<Void, Void, Void>(){

        @Override
        protected Void doInBackground(Void... params) {
            try {

                InstanceID instance = InstanceID.getInstance(mContext);

                String registrationId = instance.getToken(Constants.GCM_SENDER_ID,
                        GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);

                SharedPreferences sp = mContext.getSharedPreferences(Constants.TOKEN_DATA, Context.MODE_PRIVATE);
                SharedPreferences.Editor editor = sp.edit();
                editor.putString(Constants.REGISTRATION_ID, registrationId);
                editor.commit();

                NotificationsRegister.getInstance(mContext).register(registrationId);
            } catch(IOException e) {
                e.printStackTrace();
            }

            return null;
        }
    }.execute();

I ran into this problem today and here's what I did to troubleshoot.

First, I also was using my own sender ID when attempting to get the token. So instead, I tried using the sender ID from the examples Google provides getString(R.id.gcm_defaultSenderId)

Once I did this, I started to get a different error message SERVICE_NOT_AVAILABLE

There are several SO questions that address this, but the one that helped me out was this one.

I turned off WiFi and used a 4G connection on my phone and it worked with both the gcm_defaultSenderId and my own sender ID.

Before the registration you must check if google api is available with this fragment of code or similar:

GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
    int resultCode = apiAvailability.isGooglePlayServicesAvailable(a);
    if (resultCode == ConnectionResult.SUCCESS) { //Do the getTokencall  } else { //check the code }

Probably you are not receiving the SUCCESS resultCode. For example if there is a pending update of google api.
