ошибки во время компиляции являются:

Описание ресурсов Путь Местоположение Тип Метод OnSuccess (String) типа нового AsyncHttpResponseHandler() {} должны переопределить или реализовать супертип метод

метод OnFailure (интермедиат, Throwable, String) типа нового AsyncHttpResponseHandler() {} необходимо переопределить или реализовать супертип метода

Пожалуйста, помогите !!!

Answer 1

IMHO, вам нужно определить методы onSuccess и onFailure с использованием другой подписи. Проверьте, какую версию библиотеки вы используете, но не так ли это?

 @Override 
    public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) { 
     // Successfully got a response 
    } 

    @Override 
    public void onFailure(int statusCode, Header[] headers, byte[]  responseBody, Throwable error) { 
     // Response failed :(
    } 

Answer 2

Вы не уважаете метод оригинальный класс прототипов

onSuccess:

onSuccess(int statusCode, org.apache.http.Header[] headers, byte[] responseBody) 

onFailure:

onFailure(int statusCode, org.apache.http.Header[] headers, byte[] responseBody, java.lang.Throwable error)
