AdvertisingIdClient getAdvertisingIdInfo hangs forever

Question

I\'m trying to get advertising ID from Google Play services API. Here is a sample code:

...
import com.google.android.gms.ads.identifier.AdvertisingIdClient;
imp         


        

Answer 1

I found the reason. It shouldn't block onStart() handler because blocked context blocks Play API in ID settings obtaining. Fixed code looks like this:

@Override
protected void onStart() {
    super.onStart();
    Thread thr = new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                Context ctx = MyActivity.this.getApplicationContext();
                AdvertisingIdClient.Info adInfo = AdvertisingIdClient.getAdvertisingIdInfo(ctx);
                finished(adInfo);
            } catch (...) {
                // All exceptions blocks
            }

            finished(null);
        }
    });

    thr.start();
}

private void finished(final AdvertisingIdClient.Info adInfo){
    if(adInfo!=null){
        // In case you need to use adInfo in UI thread
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                // Do some stuff with adInfo
            }
        });
    }
}

It would be helpful if official instructions had such usage comments.
