AndroidAnnotations and EventBus

I have annotated activity in a library that is a subscriber of an EventBus event from the same library. It looks something like this: greatly simplified:

@EActivity(resName = "activity_foo") public class Foo extends Activity { public void onEvent(BarEvent event){ doSomething(); } }

It should work in accordance with this:

http://timnew.me/blog/2014/09/14/otto-and-android-annotations-compatibility-issue-analysis/

But actually it returns with this error:

Cannot start activity ... de.greenrobot.event.EventBusException: Subscriber class com.foo.bar.activities.Foo_ does not have public methods called onEvent

EventBus doesn't seem to look in the parent class. I think the @Subscribe annotation everyone is talking about is only in Guava and Otto, but not in EventBus. No one talks about compatibility issues between AA and Eventbus on the network, so I am missing something.

How can I do this job?

EventBus: 2.4

AA: 3.2

EDIT

Following WonderCsabo's answer, I upgraded EventBus to version 3.0 (including subscription annotations) and AA to 3.3.1, and the problem went away, but there is one more:

And I noticed that both problems (missing onEvent and now PostThread is only a problem in the release version. I use ProGuard with recommended exceptions for EventBus and AA).

EDIT 2 :

I added

 -keep class de.greenrobot.** {*;}

and it seems to work.

You have three options:

By the way, you should upgrade to the latest AndroidAnnotations, 3.3.1.

I have EventBus annotations working with:

 # Ensure annotations are kept for runtime use. -keepattributes *Annotation* # Don't remove any GreenRobot classes -keep class de.greenrobot.** {*;} # Don't remove any methods that have the @Subscribe annotation -keepclassmembers class ** { @de.greenrobot.event.Subscribe <methods>; }

Note that this also ensures that your method names will still be confused.

In case someone still encounters this error, with EventBus 3.0 the package has been renamed ( org instead of de and eventbus instead of event ), therefore the correct proguard configuration:

 ## GreenRobot EventBus specific rules ## # http://greenrobot.org/eventbus/documentation/proguard/ -keepattributes *Annotation* -keepclassmembers class ** { @org.greenrobot.eventbus.Subscribe <methods>; } -keep enum org.greenrobot.eventbus.ThreadMode { *; } # Only required if you use AsyncExecutor -keepclassmembers class * extends org.greenrobot.eventbus.util.ThrowableFailureEvent { <init>(java.lang.Throwable); }

as described on the site

UPDATE

This seems to be the wrong answer. The exception is anyway.

Original answer

As of EventBus 3, you can disable the subscriber exception by throwSubscriberException(false) .

By invoking this in your application class, you can disable this exception for your default event bus.

 EventBus.builder().throwSubscriberException(false).installDefaultEventBus();
