Question

我正在为我的Android应用程序使用retrofit 1.8将get请求发送到以下链接https://hamadataha-alfylovealfy.c9users.io/api/posts/1。这是我放置界面的类

package base;


import model.User;
import retrofit.Callback;
import retrofit.http.GET;
import retrofit.http.Path;

public class Interfaces {
    public interface getUser {
        @GET("/api/posts/2")
        public void getUser(Callback<User> response);
    }
}

这是RetrofitSingleton类包基;

import retrofit.*;

public class RetrofitSingleton {
    private static final String BASE_URL = "https://hamadataha-alfylovealfy.c9users.io";

    private static RestAdapter restAdapter = null;


    public static RestAdapter getInstance(){
        if (restAdapter == null){
            restAdapter = new RestAdapter.Builder()
                    .setEndpoint(BASE_URL)
                    .build();
        }
        return restAdapter;
    }

}

在我的活动中，我这样称呼请求

public void ApiTest(){
        Interfaces.getUser call = RetrofitSingleton.getInstance().create(Interfaces.getUser.class);
        call.getUser( new Callback<User>() {
            @Override
            public void success(User user, Response response) {
                setCurrentUser(new User("yessss", "yessss", "yessss"));
            }

            @Override
            public void failure(RetrofitError error) {
                setCurrentUser(new User("no,", "no", "no"));
                Log.d("hello", error.toString());
            }
        });
    }

但是，它始终以logcat

中的以下内容结束

retrofit.RetrofitError: No static field METHODS of type Ljava/util/Set; in class Lcom/squareup/okhttp/internal/http/HttpMethod; or its superclasses (declaration of 'com.squareup.okhttp.internal.http.HttpMethod' appears in /data/app/com.karim.m3-2/base.apk)

知道这个错误可能是什么？

在Android应用程序中使用改造时出错
