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 to this line,
HttpResponse resposta = client.execute(requisicao);
I get the following error in the console of RUN :
