Avoid response delay message

Question

I am developing an application that consumes, via REST, a third party service. In some cases the service takes time to answer me and, as the application is waiting for reply, a message appears offering the user the option to wait or terminate the application, as shown in the image below:

This message appears mainly when I use 3G connection to consume the service.

Is there any way to avoid this message or increase the response time indefinitely?

I didn’t use Asynctask. I tried to make some adaptations but I didn’t succeed. So I would like to know if, under these circumstances, there is a possibility of avoiding the message. If using Asynctask is the only way to avoid this scenario I would greatly appreciate the recommendation of a material (or explanation) that is understandable to someone who doesn’t have as much experience with Android as I do =)

From now on, thank you =)

Answer 1

I’m surprised you can even consume a service without using Asynctask.

Anyway. The options you have, which alias are the most common, is to use Volley or Retrofit

There’s plenty of stuff out there, like this: https://www.youtube.com/watch?v=V2nwFenaWRM

and this http://www.devmedia.com.br/android-retrofit-primeiros-passos-com-a-retrofit-api/31857

Example with Volley:

    final TextView tvMeuTextView = (TextView) findViewById(R.id.meu_textview);

    String url = "http://www.meu.server.com/meujson";

    JsonObjectRequest jsObjRequest = new JsonObjectRequest
            (Request.Method.GET, url, new Response.Listener<JSONObject>() {

                @Override
                public void onResponse(JSONObject response) {
                    tvMeuTextView.setText("Resposta do servidor: " + response.toString());
                }
            }, new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {
                    // em caso de erro na requisição, trata-o aqui
                }
            });

    //Preferencialmente crie um singleton para isso
    Volley.newRequestQueue(this).add(jsObjRequest);
