我在库中有一个带注释的 Activity,它是来自同一库的 EventBus 事件的订阅者。它看起来像这样,大大简化:
@EActivity(resName = "activity_foo")
public class Foo extends Activity {
public void onEvent(BarEvent event){
doSomething();
}
}
它应该按照以下方式工作:

但实际上它返回此错误:
无法启动活动... de.greenrobot.event.EventBusException:订阅者类 com.foo.bar.activities.Foo_ 没有称为 onEvent 的公共方法
似乎 EventBus 不在父类中。我猜每个人都在谈论的@Subscribe 注释只在 Guava 和 Otto 中,而不是在 EventBus 中。没有人在网上谈论 AA 和 Eventbus 之间的兼容性问题,所以我一定遗漏了一些东西。
我怎样才能使这项工作?
事件总线:2.4
机管局:3.2
编辑:
在 WonderCsabo 的回答之后,我将 EventBus 更新为 3.0 beta(包括订阅注释),将 AA 更新为 3.3.1,问题就消失了,但还有另一个问题:

而且我注意到这两个问题(缺少 onEvent 和现在 PostThread 只是发布版本上的一个问题。我使用 ProGuard 以及 EventBus 和 AA 的推荐例外)。
编辑 2:
我添加了
-keep class de.greenrobot.** {*;}
它似乎正在工作。
