Re: [android-developers] Re: UI getting slow on video playing

Below is the async task I am using to update the UI

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

    public boolean isStopped = false;

    @Override

    protected Void doInBackground(Void... params) {

       try {

          while (!isStopped) {

           try {

               publishProgress();

              Thread.sleep(1000);

           } catch(InterruptedException e) {

                e.printStackTrace();

           }

        }

      }catch(Exception e) {

          e.printStackTrace();

      }

      return null;

  }

  @Override

   protected void onProgressUpdate(Void... values) {

       //Code to update UI

   }

}
