Get Post methodlarında Cookie aktarım sorunu

try{
                    OkHttpClient client = new OkHttpClient.Builder()
                            .cookieJar(new CookieJar() {
                                private final HashMap<HttpUrl, List<Cookie>> cookieStore = new HashMap<>();

                                @Override
                                public void saveFromResponse(HttpUrl url, List<Cookie> cookies) {
                                    cookieStore.put(url, cookies);
                                }

                                @Override
                                public List<Cookie> loadForRequest(HttpUrl url) {
                                    List<Cookie> cookies = cookieStore.get(url);
                                    return cookies != null ? cookies : new ArrayList<Cookie>();
                                }
                            })
                            .build();
                    Request request = new Request.Builder().url(Global.url+"/api/csrf").build();
                    Response response = client.newCall(request).execute();
                } catch (Exception e){
                    Log.v("----",e.getMessage());
                }

Selamlar,

Yukarıdaki şekilde denediğimde uygulama kapanıyor. Sorun ne olabilir.

okhttp için : 

OkHttpClient client = new OkHttpClient.Builder()
    .cookieJar(new CookieJar() {
        private final HashMap<HttpUrl, List<Cookie>> cookieStore = new HashMap<>();

        @Override
        public void saveFromResponse(HttpUrl url, List<Cookie> cookies) {
            cookieStore.put(url, cookies);
        }

        @Override
        public List<Cookie> loadForRequest(HttpUrl url) {
            List<Cookie> cookies = cookieStore.get(url);
            return cookies != null ? cookies : new ArrayList<Cookie>();
        }
    })
    .build();

şeklinde kullanabilirsin ya da java.net.CookieManager kullanabilmek için okhttp-urlconnection'ı projene eklemen gerek.

dependencies {
    compile "com.squareup.okhttp3:okhttp-urlconnection:3.0.0"
}

CookieManager cookieManager = new CookieManager();
cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
OkHttpClient client = new OkHttpClient.Builder()
    .cookieJar(new JavaNetCookieJar(cookieManager))
    .build();
