在Android 4.4.4上修复SSL错误

Question

我们有一个现有的Android应用程序，它使用Retrifit连接到服务器并发送和接收JSON。自从将我的设备更新到Android4.4.4后，我在尝试连接时遇到以下错误：

我已经更新到最新版本的retrifit/OkHTTP和Okio，但是错误仍然存在。我猜这与Android 4.4.4中的OpenSSL补丁有关，但我找不到解决这个错误的方法。

为了在Pre-lollipop Android中使用referfit，您应该使用OKHTTP的较低版本，并强制实现支持Pre-lollipop的特定版本

implementation 'com.squareup.retrofit2:converter-gson:2.9.0'
implementation 'com.squareup.retrofit2:retrofit:2.9.0'
implementation ("com.squareup.okhttp3:okhttp:3.12.12"){
    force = true //API 19 support
}
