Question

我已将ProGuard添加到我的项目中并收到此错误。我想它可以是Jsoup lib，我用来发送POST和GET请求并解析响应。

没有单独的行可以抛出此异常。

你能用ProGuard帮我解决这个问题吗？

Answer 1

不要在proguard中添加解析类以获得混淆。保持原样。在proguard文件中写下以下行

 -keep class yourclassname.** { *; }

Answer 2

Proguard已经跳过了一些所需的文件，执行此操作

-keep <your calss name>.** {
  *;
}

这将确保proguard在混淆时不会跳过它们

将ProGuard添加到项目后出现异常
