Sirs, very good day / afternoon / evening!
I'm having problems with word accentuation. The backend of my system works in PHP by talking to an Android app. When I send the message from the App to the server PHP works normally, and PHP responds as expected, but if the message sent to PHP includes characters with an accent the App presents an error and stops.
I've researched of course, but a lot of people are using HttpClient and I'm using HttpURLConnection.
I have tried to include a line saying RequestProperty is UTF-8, but it did not work.
Follow the Connection class I'm using.
package Conexao;
import android.util.Log;
import org.json.JSONArray;
import org.json.JSONObject;
import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class Conexao {
private static Conexao instancia;
public static String urlString;
private Conexao() {
//nothing
}
public static Conexao getInstancia() {
if (instancia == null) {
instancia = new Conexao();
}
return instancia;
}
public static JSONArray executePost(JSONObject json) {
JSONArray jsonArray = null;
try {
URL url = new URL(urlString);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("contentType", "application/json");
conn.connect();
conn.setConnectTimeout(1000);
DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
wr.writeBytes(json.toString());
InputStream is = conn.getInputStream();
BufferedReader streamReader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
StringBuilder responseStrBuilder = new StringBuilder();
String inputStr;
while ((inputStr = streamReader.readLine()) != null)
responseStrBuilder.append(inputStr);
jsonArray = new JSONArray(responseStrBuilder.toString());
} catch (Exception e) {
Log.e("Erro ", e.toString());
}
Log.i("Resposta: ", jsonArray.toString());
return jsonArray;
}
}
Thanks in advance.

Gentlemen, I'm doing tests and the following excerpt I removed from my debug:
json = {JSONObject@18906} "{"cha_gru_codigo":"1","cha_pes_usuario":"3","cha_solicitacao":"zé","cha_des_texto":"zinho","classe":"chamado","acao":"usuAbrirChamado"}"
jsonArray = null
url = {URL@18958} "http://www.solusinformatica.890m.com/SCT/SCT/facade/Facade.php"
conn = {HttpURLConnectionImpl@18961} "com.android.okhttp.internal.http.HttpURLConnectionImpl:http://www.solusinformatica.890m.com/SCT/SCT/facade/Facade.php"
wr = {DataOutputStream@18978}
is = {RealBufferedSource$1@18992} "buffer(com.android.okio.GzipSource@2be6139).inputStream()"
streamReader = {BufferedReader@18997}
responseStrBuilder = {StringBuilder@19002} ""
inputStr = {String@19007} "Nenhum comando selecionado - <pre>null</pre>"
This last inputStr field is the variable that received the Backend response and the field between the pre tags, with null value is what the backend received from the Android App, that is, when the message has an accent the backend does not receive the data, I think because Android simply does not send them.
I tried to apply the solution described in the post:
The App this time sent the message, but PHP received it like this: ze = z% C3% A9
