my mainActivity mtehod to call the api is 
 

 
Github api = GitHubService.getService(); 
 
     api.getRepo("basil2style", new Callback<Repository>() { 
 
      @Override 
 
      public void onResponse(Call<Repository> call, Response<Repository> response) { 
 

 
      }

请分享堆栈跟踪和分享改装的版本，以及...像β2或3 .... –

com.squareup.retrofit2：改造：2.0.0-BETA4 –

请分享堆栈跟踪.. –

您有加入也改造2你需要调用封装API请求的okHttp客户的依赖到你的项目或可观察到的使用RxJava适配器这里是你如何能请致电

所以你的情况的界面应该是

@GET("https://stackoverflow.com/users/{user}") 
    public Call<Repository> getRepo(@Path("user") String user);

和调用代码应该像

Call<Repository> call = apiService.getUser(username); 
call.enqueue(new Callback<Repo>() { 
    @Override 
    public void onResponse(Response<Repo> response) { 
    } 

    @Override 
    public void onFailure(Throwable t) { 

    } 
});

有了叫你也可以取消正在进行的API调用您可以阅读这些教程更info https://github.com/square/retrofit/tree/master/samples/src/main/java/com/example/retrofit https://guides.codepath.com/android/Consuming-APIs-with-Retrofit
