将 ProGuard 添加到项目后出现异常

Question

我已将 ProGuard 添加到我的项目并收到此错误。我猜它可能是我用来发送 POST 和 GET 请求并解析响应的 Jsoup lib。

没有单独的行会引发此异常。

你能帮我用 ProGuard 解决这个问题吗？

Answer 1

不要在你的 proguard 中添加解析类来混淆。 保持原样。在您的 proguard 文件中写入以下行

 -keep class yourclassname.** { *; }

Answer 2

Proguard 已跳过一些需要的文件，请执行此操作

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

这将确保 proguard 在混淆时不会跳过它们
