Automatic cookie handling with OkHttp 3

If you want to use the new OkHttp 3 CookieJar and get rid of the okhttp-urlconnection dependency you can use this PersistentCookieJar.

You only need to create an instance of PersistentCookieJar and then just pass it to the OkHttp builder:

CookieJar cookieJar =
                    new PersistentCookieJar(new SetCookieCache(), new SharedPrefsCookiePersistor(context));

OkHttpClient okHttpClient = new OkHttpClient.Builder()
                    .cookieJar(cookieJar)
                    .build();
