我正在尝试解决从我的设备（android 4.4.2）向后端发送数据的问题，但它引发了异常：

但是当我在模拟器（android 7.0）上运行我的应用程序时，它的工作正常... 我正在使用改装v2请求：
HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();
httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
CLIENT = new OkHttpClient.Builder()
.addInterceptor(httpLoggingInterceptor)
.build();
gson = new GsonBuilder()
.setLenient()
.create();
return new Retrofit.Builder()
.baseUrl(mysite)
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create(gson))
.client(CLIENT).build();
