android - 生成安全签名 APK 时出现 Proguard 错误

Question

从过去 2 天开始，我一直在尝试为我的应用程序生成安全签名的 apk，但仍然没有取得任何成功。

我检查了很多 StackOverflow 的答案并尝试了所有解决方案，但没有一个对我有用。所以我在这里，如果有人能帮助我，我将非常感激并非常感谢您的帮助。

下面是我在生成安全签名的 apk 时遇到的错误。

已编辑:

我的 proguard 文件有一些变化，现在我遇到了以下错误

  Proguard returned with error code 1. See console
Note: there were 209 duplicate class definitions.
You should check if you need to specify additional program jars.

我已通过在我的 proguard.cfg 文件中添加以下两行来解决我的问题。

-keep class android.support.v4.** { ; }
-dontwarn android.support.v4.*
