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

Question

代码没有问题所以我只是复制错误。我正在使用 okhttp 3.12.0 从互联网上获取一些东西(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"

或

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 的依赖项 Kotlin stdlib。

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

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