I have the following class:

package carcleo.com.radiosingular.classes;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URI;

import android.os.AsyncTask;
import android.util.Log;

import com.loopj.android.http.HttpGet;

import org.json.JSONObject;

import cz.msebera.android.httpclient.HttpResponse;
import cz.msebera.android.httpclient.client.HttpClient;
import cz.msebera.android.httpclient.impl.client.HttpClients;

public class DownloadDados extends AsyncTask<String, Void, JSONObject> {

    JSONObject clientes = null;

    @Override
    public JSONObject doInBackground(String... params) {

        String URL = params[0];
        String linha = "";
        Boolean erro = false;

        try {

            HttpClient client = HttpClients.createDefault();

            HttpGet requisicao = new HttpGet();

            requisicao.setURI(new URI(URL));

            HttpResponse resposta = client.execute(requisicao);

            BufferedReader br = new BufferedReader(new InputStreamReader(resposta.getEntity().getContent()));

            StringBuffer sb = new StringBuffer("");

            while ((linha = br.readLine()) != null) {
                sb.append(linha);
            }

            br.close();

            linha = sb.toString();


            Log.v("Será: ",linha);

            clientes = new JSONObject(linha);

        } catch (Exception e) {
            Log.v("Erro: ", e.getMessage());
        }

        return clientes;

    }

}

When you get on that line,

            HttpResponse resposta = client.execute(requisicao);

I get the following error in console of RUN :

  • The problem is that the variable linha this null here > Log.v("Será: ",linha); According to the error message to message cannot be empty.

  • I didn’t understand your comment, the error occurs well before, in the line Httpresponse response = client.execute(requisicao); In addition, I can comment or even delete essw Log. v that the error continues.

  • Yes... the cause of the first mistake is ClassNotFoundException who did not find the class android.view.View$OnUnhandledKeyEventListener on the roads....

  • Probably missing things in that package there. And from what I’ve seen this Class is obsolete.

  • so, I found, and it’s the same error of another question I asked, you need to put Strictmode.Threadpolicy = new Strictmode.ThreadPolicy.Builder(). permitAll(). build(); for intenet access to work. Are these libraries deprecated? There is newer code for this?

  • the other question is https://answall.com/questions/352332/problemas-com-strictmode-threadpolicy

  • I have never used these libraries. To make web service connections I usually use the Volley.
