¿Cómo poner el identificador de sesión de Cookie en la solicitud de volea? (2)

Entonces el problema fue conseguir una cookie válida. Mi error fue obtenerlo desde la propia solicitud POST. Mantuve el mismo principio de funcionamiento: obtuve la cookie cuando inicié la aplicación, pero usé GET en lugar de POST y llamé la raíz de la URL en lugar de la dirección donde obtengo el JSON.

Mi solución se veía así:

public void requestCookie() {
  queue = Volley.newRequestQueue(this);
  String url = "http://myurl.com/";

  StringRequest getRequest = new StringRequest(Request.Method.GET, url,
   new Response.Listener <String> () {
    @Override
    public void onResponse(String response) {
     String x = myCookieManager.getCookieValue();
    }
   },
   new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
     Log.d("ERROR", "Error => " + error.toString());
     hideLoading();
    }
   }
  ) {   
   protected Response <String> parseNetworkResponse(NetworkResponse response) {
    try {
     String jsonString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
     String header_response = String.valueOf(response.headers.values());
     int index1 = header_response.indexOf("PHPSESSID=");
     int index2 = header_response.indexOf("; path");
     //Log.e(Utils.tag, "error is : " + index1 + "::" + index2);
     session_id = header_response.substring(index1, index2);

     return Response.success(jsonString, HttpHeaderParser.parseCacheHeaders(response));
    } catch (UnsupportedEncodingException e) {
     return Response.error(new ParseError(e));
    }
   }
  };

  queue.add(getRequest);
 }

Entonces, tengo este código para hacer una solicitud POST con volley:

public class MainActivity extends AppCompatActivity {

 Button btnSearch;
 ProgressDialog loadingDialog;
 ListView lvResult;
 String session_id;
 RequestQueue queue;
 MyCookieManager myCookieManager;

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

  btnSearch = (Button) findViewById(R.id.btnSearch);
  lvResult = (ListView) findViewById(R.id.lvResult);
  loadingDialog = new ProgressDialog(MainActivity.this);
  loadingDialog.setMessage("Wait.\nLoading...");
  loadingDialog.setCancelable(false);
  myCookieManager = new MyCookieManager();

  requestCookie(); //FIRST CALL TO GET SESSION ID

  btnSearch.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View view) {
    showLoading();
    requestWithSomeHttpHeaders(); //CALL TO MAKE THE REQUEST WITH VALID SESSION ID
   }
  });

 }

 public void requestCookie() {
  queue = Volley.newRequestQueue(this);
  String url = "http://myurl.com/json/";

  StringRequest postRequest = new StringRequest(Request.Method.POST, url,
   new Response.Listener < String > () {
    @Override
    public void onResponse(String response) {
     //
     String x = myCookieManager.getCookieValue();
    }
   },
   new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
     Log.d("ERROR", "Error => " + error.toString());
     hideLoading();
    }
   }
  ) {
   @Override
   public byte[] getBody() throws AuthFailureError {
    String httpPostBody = "param1=XPTO&param2=XPTO";
    return httpPostBody.getBytes();
   }

   @Override
   public Map < String, String > getHeaders() throws AuthFailureError {
    Map <String, String> params = new HashMap < String, String > ();
    params.put("User-Agent", "Mozilla/5.0");
    params.put("Accept", "application/json, text/javascript, */*; q=0.01");
    params.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
    //params.put("Set-Cookie", session_id);// + " _ga=GA1.3.1300076726.1496455105; _gid=GA1.3.1624400465.1496455105; _gat=1; _gali=AguardeButton");
    //"PHPSESSID=ra0nbm0l22gsnl6s4jo0qkqci1");
    return params;
   }

   protected Response <String> parseNetworkResponse(NetworkResponse response) {
    try {
     String jsonString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
     String header_response = String.valueOf(response.headers.values());
     int index1 = header_response.indexOf("PHPSESSID=");
     int index2 = header_response.indexOf("; path");
     //Log.e(Utils.tag, "error is : " + index1 + "::" + index2);
     session_id = header_response.substring(index1, index2);

     return Response.success(jsonString, HttpHeaderParser.parseCacheHeaders(response));
    } catch (UnsupportedEncodingException e) {
     return Response.error(new ParseError(e));
    }
   }
  };

  queue.add(postRequest);
 }

 public void requestWithSomeHttpHeaders() {
  queue = Volley.newRequestQueue(this);
  String url = "http://myurl.com/json/";

  StringRequest postRequest = new StringRequest(Request.Method.POST, url,
   new Response.Listener <String> () {
    @Override
    public void onResponse(String response) {
     Log.d("Response", response);
     String x = myCookieManager.getCookieValue();
     String status = "";

     try {
      JSONObject resultObject = new JSONObject(response);
      Log.d("JSON RESULT =>", resultObject.toString());
     } catch (JSONException e) {
      Toast.makeText(MainActivity.this, "Request Error", Toast.LENGTH_SHORT).show();
      e.printStackTrace();
     }

     hideLoading();
    }
   },
   new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
     Log.d("ERROR", "Error => " + error.toString());
     hideLoading();
    }
   }
  ) {
   @Override
   public byte[] getBody() throws AuthFailureError {
    String httpPostBody = "param1=XPTO&param2=XPTO";
    return httpPostBody.getBytes();
   }

   @Override
   public Map <String, String> getHeaders() throws AuthFailureError {
    Map <String, String> params = new HashMap <String, String> ();
    params.put("User-Agent", "Mozilla/5.0");
    params.put("Accept", "application/json, text/javascript, */*; q=0.01");
    params.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
    params.put("Cookie", /*myCookieManager.getCookieValue()*/ session_id + "; _ga=GA1.3.1300076726.1496455105; _gid=GA1.3.1624400465.1496455105; _gat=1; _gali=AguardeButton");
    return params;
   }
  };

  queue.add(postRequest);
 }

 private void showLoading() {
  runOnUiThread(new Runnable() {
   @Override
   public void run() {
    if (!loadingDialog.isShowing())
     loadingDialog.show();
   }
  });
 }

 private void hideLoading() {
  runOnUiThread(new Runnable() {
   @Override
   public void run() {
    if (loadingDialog.isShowing())
     loadingDialog.dismiss();
   }
  });
 }
}

Si envío una ID de cookie válida, esto devolverá un objeto JSON válido, o un objeto vacío.

Intenté (sin éxito) establecer los manejadores de cookies predeterminados como

CookieManager manager = new CookieManager(); CookieHandler.setDefault(manager);

Pero me sale un objeto vacío.

¿Cómo poner un ID de sesión de cookie válido para publicar solicitud?
