En mi solicitud, envío una solicitud POST a un servidor y recibo una respuesta del servidor. Y de la respuesta obtengo diferentes cookies, información del usuario específicamente. Por lo tanto, envío una solicitud de inicio de sesión y recibo las cookies después de que el servidor responde, para mantener el inicio de sesión. En Android 4.3 y versiones posteriores, recibo las cookies perfectamente y el usuario inicia sesión con éxito. Pero en Android 4.4, el usuario inicia sesión correctamente, pero no se reciben cookies.

¿Android ha cambiado algo significativo para que esto ocurra? Aquí está mi código a continuación si alguien tiene alguna sugerencia.
