运行ProGuard后，我的自定义批注出现问题

以下是相关代码：

A类延伸至B类

抽象B类

谢谢。

下面的代码对我来说总是有用的

-keepattributes Annotation

以下声明似乎解决了问题：

-keep @com.mycompany.myapp.MyAnnotation interface * {
*;
} 

...
@MyAnnotation
public interface CustomInterface {
}
...

// mClass never found since MyAnnotation seems to be disappeared
// after obfuscation
for (Class<?> c : getClass().getClasses()) {
    for (Annotation annotation : c.getAnnotations()) {
        if (annotation instanceof MyAnnotation) {
            mClass = c;

            break;
        }
    }
}

-keepattributes *Annotation*

-keep @com.mycompany.myapp.MyAnnotation interface * {
*;
}
