Answer 1

Fetch the advertising id from background thread:

    AsyncTask.execute(new Runnable() {
        @Override
        public void run() {
            try {
                AdvertisingIdClient.Info adInfo = AdvertisingIdClient.getAdvertisingIdInfo(mContext);
                String adId = adInfo != null ? adInfo.getId() : null;
                // Use the advertising id
            } catch (IOException | GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException exception) {
                // Error handling if needed
            }
        }
    });

I added null checks to prevent any crashes. The Google example implementation code would crash with a NullPointerException if an exception occures.
