Problem Getting Data from Openweathermap Android Service

Question

Good morning,

I have not yet been able to get this little app up and running, and now there is no value in temperature, humidity or wind.

I think the problem is in my implementation of the object that later cannot be loaded with the values received from the service...

Mainactivity:

public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {

private static final String APP_ID = "api_id";

private static final int PERMISSION_ACCESS_COARSE_LOCATION = 1;
private GoogleApiClient googleApiClient;

private TextView textView;
private TextView textView_humidity;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    textView = (TextView) findViewById(R.id.textView);

    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
            != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, new String[] { Manifest.permission.ACCESS_COARSE_LOCATION },
                PERMISSION_ACCESS_COARSE_LOCATION);
    }

    googleApiClient = new GoogleApiClient.Builder(this, this, this).addApi(LocationServices.API).build();
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case PERMISSION_ACCESS_COARSE_LOCATION:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // All good!
            } else {
                Toast.makeText(this, "Need your location!", Toast.LENGTH_SHORT).show();
            }

            break;
    }
}

@Override
protected void onStart() {
    super.onStart();
    if (googleApiClient != null) {
        googleApiClient.connect();
    }
}

@Override
protected void onStop() {
    googleApiClient.disconnect();
    super.onStop();
}

@Override
public void onConnected(Bundle bundle) {
    Log.i(MainActivity.class.getSimpleName(), "Connected to Google Play Services!");

    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
            == PackageManager.PERMISSION_GRANTED) {
        Location lastLocation = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);

        double lat = lastLocation.getLatitude();
        double lon = lastLocation.getLongitude();

        String units = "metric";
        String url = String.format("http://api.openweathermap.org/data/2.5/weather?lat=%f&lon=%f&units=%s&appid=%s",
                lat, lon, units, APP_ID);
        new GetWeatherTask(textView).execute(url);
    }
}

@Override
public void onConnectionSuspended(int i) {

}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
    Log.i(MainActivity.class.getSimpleName(), "Can't connect to Google Play Services!");
}

private class GetWeatherTask extends AsyncTask<Meteo, Void, Meteo> {
    private TextView textView;
    private TextView textView_humidity;

    public GetWeatherTask(TextView textView) {
        this.textView = textView;
    }


    @Override
    protected Meteo doInBackground(Meteo... params) {
        Meteo meteo = new Meteo();
        String weather = "UNDEFINED";

        try {
            URL url = new URL(params[0]);
            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

            InputStream stream = new BufferedInputStream(urlConnection.getInputStream());
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(stream));
            StringBuilder builder = new StringBuilder();

            String inputString;
            while ((inputString = bufferedReader.readLine()) != null) {
                builder.append(inputString);
            }


            JSONObject topLevel = new JSONObject(builder.toString());
            JSONObject main = topLevel.getJSONObject("main");
            meteo.temperatura = String.valueOf(main.getDouble("temp"));
            meteo.humidade = String.valueOf(main.getDouble("humidity"));

            urlConnection.disconnect();
        } catch (IOException | JSONException e) {
            e.printStackTrace();
        }
        return meteo;
    }

    @Override
    protected void onPostExecute(Meteo meteo) {
        textView.setText("Current Weather: " + meteo.temperatura + " ºC");
        textView.setText("Current Humidity: " + meteo.humidade + " ºC");
    }
}

}

Meteo:

public class Meteo {

public String temperatura;
public String humidade;
public String vento;

public Meteo()
{
    temperatura = "";
    humidade = "";
    vento = "";
}

public Meteo(String tEmperatura, String hUmidade, String vEnto)
{
    temperatura = tEmperatura;
    humidade = hUmidade;
    vento = vEnto;
}

public String getTemperatura(){
    return temperatura;
}

public String getHumidade (){
    return humidade;
}

public String getVento()
{
    return vento;
}

}

I don’t see what I might be doing wrong, since I adapted this example to use the Meteo object and can return more than one parameter, because in the original example it returned only one String temperature.

Someone can help me understand and fix the situation?
