OkHttp在Android4.x手机上报错java.lang.

最近在自测的时候，用的是三星note3手机跑项目居然报错 java.lang.ExceptionInInitializerError

     Caused by: java.lang.IllegalStateException: Expected Android API level 21+ but was 19

在错误信息中发现了 java.lang.IllegalStateException: Expected Android API level 21+ but was 19 应该就是版本的问题，然后去OkHttp官网查看确实是版本问题

目前我项目用的是 4.x以上的，人家文中说的很清楚想要兼容Android2.3+就得切换到 3.12.X

所以 implementation ("com.squareup.okhttp3:okhttp:3.12.0") 重新编译就OK了。
