Tienda de cookies persistente con okhttp 2 en Android

Puede configurar su CookieStore en el cliente OkHttp con el siguiente código:

 OkHttpClient client = new OkHttpClient(); client.setCookieHandler(new CookieManager( new PersistentCookieStore(getApplicationContext()), CookiePolicy.ACCEPT_ALL)); 

Hice una idea con mi implementación de una persistente CookieStore tratando de mejorar la respuesta de janoliver en dos puntos:

1. En base a esta respuesta, el URI no debe utilizarse si los atributos de dominio y ruta de las cookies están disponibles.
2. En la clase SerializableHttpCookie, el atributo HTTPOnly de HttpCookie no está serializado (no tiene accesores ni mutadores). Mi solución fue usar la reflexión para poder acceder a este atributo privado.

Poner el código en la función onCreate una Application personalizada resuelve el problema. Ahora funciona.

 public class MyApplication extends Application { public void onCreate() { super.onCreate(); // enable cookies java.net.CookieManager cookieManager = new java.net.CookieManager(); cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL); CookieHandler.setDefault(cookieManager); } } 

Me las arreglé para obtener cookies persistentes con okhttp con la CookieStore siguiente, que se copió parcialmente de la de android-async-http . Funciona con API lvl 9 y tal vez menos.
