Saludos, perdon si estoy enel foro equivocado, bueno les cuento tengo una aplicacion android en la cual debo controlar si los datos ingresados en una caja de texto son correctos es decir si ingreso un numero de cedula lo valido y presentar un mensaje de error si no es correcto o si dicha caja de texto esta vacia...bueno lo que hago es mandar lo que esta en esa caja de texto hacia un php y trabajo con JSON hago todas las validaciones y devuelvo un "1" si todo esta correcto o "0" si algo anda mal, el problema esque si devuelve un "0" JSON y eso trato de capturar en android pues me da un error, es decir el JSON desde php me manda "1" o "0" y eso en java lo pongo para validar asi:
Código:
try {
int success = json.getInt(TAG_SUCCESS);
if (success == 1) {
Intent i = getIntent();
setResult(100, i);
finish();
}
if (success == 0)
{
Toast.makeText(getApplicationContext(), "Espere hay un error...", Toast.LENGTH_SHORT).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
aqui lo que hago es preguntar si JSON devolvio un "1" o "0" cuando recive el "1" todo marcha bien y hago algo...pero cuando recibo un "0" se cancela la palicacion....alguien que me ayude con esto por favor le pongo error que me muestra el log CAt
Código:

Y este es el codigo que tengo en el php y JSON.
Código PHP:
// array for JSON response
$response = array();
// check for required fields
if (isset($_POST['nombre']) && isset($_POST['cedula']) && isset($_POST['apellido'])) {
$nombre = $_POST['nombre'];
$cedula = $_POST['cedula'];
$apellido = $_POST['apellido'];
$sueldo = $_POST['sueldo'];
// include db connect class
// require_once __DIR__ . '/db_connect.php';
include("db_connect.php");
// connecting to db
$db = new DB_CONNECT();
// mysql inserting a new row
$result = mysql_query("INSERT INTO empleados(cedula, nombre, apellido, sueldo) VALUES('$cedula', '$nombre', '$apellido', '$sueldo')");
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "Empleado successfully created.";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
// echoing JSON response
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}
