avoiding NetworkOnMainThreadException

Question

I\'ve understood that a network operation is not allowed on the GUI thread. Ok for me. But why using this code on a Dialog button click callback still produce NetworkOnMai

Answer 1

SLaks is right, but for Android there is a more delicate way: AsyncTask.

new AsyncTask(){

    @Override
    protected Void doInBackground(Void... params){
        //Do heavy stuff
    }

    @Override
    protected void onPostExecute(Void result){
        //Do UI stuff after heavy stuff
    }
}.execute();
