in Release app (proguard config open),PersistentCookieStore can't get stored cookies,.. ``` java PersistentCookieStore defaultStore = new PersistentCookieStore(BaseApplication.getContext()); client.setCookieStore(defaultStore); ``` in **PersistentCookieStore.java**: ``` java protected Cookie decodeCookie(String cookieString) { byte[] bytes = hexStringToByteArray(cookieString); ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes); Cookie cookie = null; try { ObjectInputStream objectInputStream = new ObjectInputStream(byteArrayInputStream); cookie = ((SerializableCookie) objectInputStream.readObject()).getCookie(); Utils.showToast("decode cookie complete!"); } catch (Exception e) { } return cookie; } ``` --- if I enable the proguard config, decodeCookie always return null; and If disable pro guard config,everything is ok how can I modify the proguard-project.txt??
