答案 0 :(得分：0)
只是一个猜测，但错误存在于Retrofit的传递依赖中，称为Okhttp。
Retrofit不再处于测试阶段。您可以浏览并升级您的库。
compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'com.squareup.retrofit:converter-gson:2.3.0'
就个人而言，我会像这样重写，以便始终保持版本一致
ext {
retrofitVer = '2.3.0'
}
dependencies {
...
compile "com.squareup.retrofit2:retrofit:${retrofitVer}"
compile "com.squareup.retrofit:converter-gson:${retrofitVer}"
}
同样应该应用于支持库，Google Play和Firebase
