Show me error for line 88 and line 88 is -keep com.app.app.utils.custom_view.** { *;} !

How can i fix it?

得分: 0

根据错误提示,您在您的 ProGuard 规则中存在语法错误,即在关键字 keep 之后需要在提供名称之前指定类型。

在这种情况下,您漏掉了单词 class

只需将以下行进行更改:

-keep com.app.app.utils.custom_view.** { *;}

更改为:

-keep class com.app.app.utils.custom_view.** { *;}

有关自定义规则文件的更多信息,请阅读 ProGuard 手册

英文:

As the error specifies, you have a syntax error in your ProGuard rules which is after the keyword keep you need to specify the type before providing the name.

In this case you are missing the word class.

Just change the line

-keep com.app.app.utils.custom_view.** { *;}

to

-keep class com.app.app.utils.custom_view.** { *;}

For more information about customizing your rules file, read the ProGuard Manual.
