How to avoid Admob blocking the UI thread

Question

I have detected some of my activities are blocked at the launch. So I wrote that code in a new project:

public class LayoutTestActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        long now = System.currentTimeMillis();

        new AdView(this, AdSize.BANNER, "MY_ID");

        Log.e("Admob Test","The UI was blocked "+(System.currentTimeMillis()-now)+"ms");
    }
}

And the result is that the first creation of an AdView object blocks the UI thread for between 1 and 2 seconds.

Is there some way of avoiding that?

Thanks

Here is my solution:

  public class YHYBackgroundThread extends AsyncTask<Object, Object, Object> {
        private YHYBackgroundListener mListener;
        private Context context;
    
        public YHYBackgroundThread(Context context) {
    
            this.context= context;
    
        }
    
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
    
    
    
        }
    
        @Override
        protected Object doInBackground(Object... params) {
    
            if(mListener != null){
                return  mListener.onBackground(params);
            }
    
            return null;
        }
    
        @Override
        protected void onPostExecute(Object t) {
            if (mListener != null) {
    
    
                mListener.onPostExecute(t);
                
            }
        }
    
        public YHYBackgroundThread setListener(YHYBackgroundListener mListener){
    
            this.mListener = mListener;
    
            return this;
        }
    
    }

YHYBackgroundListener

public interface YHYBackgroundListener {

    Object onBackground(Object... params);
    void onPostExecute(Object list);
}

call this, when you need show ads

   new YHYBackgroundThread(context).setListener(


                    new YHYBackgroundListener() {
                        @Override
                        public Object onBackground(Object... params) {

                            AdRequest request = new AdRequest.Builder().build();


                            return request;
                        }

                        @Override
                        public void onPostExecute(Object list) {

                            AdRequest request = (AdRequest) list;
                            adView.loadAd(request);
                        }
                    }
            ).execute();

I had a similar issue. Resolved it by delaying the ad-request for 1 second (which gives time for the AdView to load and not block the UI.

        new Timer().schedule(new TimerTask()
        {
            @Override
            public void run()
            {
                MainActivity.runOnUiThread(new Runnable()
                {
                    @Override
                    public void run()
                    {
                        AdRequest adRequest = new AdRequest.Builder()
                                .addTestDevice(AD_TEST_DEVICE)
                                .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                                .build();

                        adView.loadAd(adRequest);
                    }
                });
            }
        }, 1000);
