使用 okhttp-3.12.0 Android 找不到类"kotlin.text.Charsets"错误

Question

代码没有任何问题，所以我只是复制错误。我正在使用okhttp 3.12.0从互联网上获得一些东西(在Android编程中(

下一行可能是主要问题：

java.lang.ClassNotFoundException: Didn't find class "kotlin.text.Charsets"

Answer 1

您必须为Okio使用Kotlin stdlib依赖项。要么使用OkHttp所依赖的Okio 1.1.15，要么包括Okio 2.0所依赖的Kotlin stdlib。

从MvnRepository下载Okio 1.1.15.jar并将其添加到lib文件夹中，然后配置依赖

implementation files('libs/okio-1_15_0.jar')
