我正在使用Retrofit来处理来自Mobile的ServersIDe数据.实施改造后,我得到以下例外.

我究竟做错了什么？

改造初始

mRetrofit = new Retrofit.Builder()                    .baseUrl(AppConstance.APP_URL)                    .addConverterFactory(ScalarsConverterFactory.create())                    .addConverterFactory(GsonConverterFactory.create())                    .clIEnt(getokhttpClIEnt())                    .build();

解决方法:

这是Gradle bulID配置问题我也有同样的问题

在Gradle你的使用

compile 'com.Google.androID.gms:play-services:8.4.0'

Enire Google Playservice lib可以更改您的项目中使用的lib

例

com.Google.androID.gms:play-services-gcm:8.4.0 com.Google.androID.gms:play-services-maps:8.4.0com.Google.androID.gms:play-services-auth:8.4.0

请参阅此URl https://developers.google.com/android/guides/setup#add_google_play_services_to_your_project
