当我启用minify时处理任务时出现异常。

Question

这个问题很容易解释，我错了

处理任务时的异常java.io.IOException: java.lang.ArrayIndexOutOfBoundsException: 4

在建造APK的时候。起初，我没有启用minify，它起作用了(但是生成了NoClassFoundError)。这就是我在build.gradle文件中启用minify的原因。一开始，我收到了很多来自专业警卫的警告，所以我忽略了所有使用-dontwarn的警告。在忽略所有警告之后，我得到了上述异常。我不知道出了什么问题。在这里，我已经附加了gradle文件和专业护卫内容。

Answer 1

使用-dontwarn与org.**域是awfu，它忽略了广泛的错误，您应该避免使用它！

您只需添加一些库推荐我们的保护规则。

但是，此错误意味着obfuscation中的某些类已经更改，您应该找到哪些类具有此条件。在此之后，只需添加以下规则来保留这些内容：

-keep class packagename.* { *; }
