java - Proguard 和两个项目使用相同的 android 库。广播。类未找到异常

Question

问题:我有 2 个应用程序。他们通过广播相互交互。我在android库中有parcelable类(它们在库中发送类的内容)。所以在使用 Proguard 之后我得到了 ClassNotFondException。怎么解决？

Answer 1

需要将 Parcelable 类添加到 proguard-project.txt 文件中，然后在项目上再次运行 proguard。

例如，您可能希望将以下内容添加到您的 proguard-project.txt 文件中，当然替换您的类的完全限定名称:

-keep public class com.example.MyParcelableClass
