Eventbus: org.greenrobot.eventbus.EventBusException: Subscriber class XXX and its super classes have no public methods with the @Subscribe annotation

[PanWangJ]

I'm trying to use EventBus in my project, but I'm stuck with a strange exception thrown by EventBus when trying to get my App running.

The case is I'm using EventBus in a custom view where I register EventBus in the onAttachToWindow() method and unregister it in the onDetachFromWindow() method. And then I created a method like this:

@Subscribe(threadMode = ThreadMode.MAIN)
public void onEventReceived(MessageEvent event) {
    //TODO
}

The problem is when I run the App, an exception is thrown which is really weird:
org.greenrobot.eventbus.EventBusException: Subscriber class XXX and its super classes have no public methods with the @Subscribe annotation

Can anyone help with this? Any suggestions is welcomed.

Have you removed those methods using Proguard perhaps?

Suggest first make sure the order of the event's coming and the registering is right

@william-ferguson-au Yes, Proguard is the cause, after modify the Proguard config, it's working now. Thanks!
