RxBus 2.x don't support return-object of interface's type and parameter of interface's type ?

    @Subscribe(
            thread = EventThread.NEW_THREAD,
            tags = {@Tag(Constants.EventType.EAT_MORE)}
    )
    public void eatMore(List<String> foods) {
        Log.i(TAG, "eat: foods => " + foods);
    }

    @Produce(
            thread = EventThread.NEW_THREAD,
            tags = {@Tag(Constants.EventType.EAT_MORE)}
    )
    public List<String> produceMoreFood() {
        return Arrays.asList("banana", "apple", "egg");
    }

log info here:

Caused by: java.lang.IllegalArgumentException: Method public void com.hwangjr.rxbus.app.TestActivity.eatMore(java.util.List) has @subscribe annotation on interface java.util.List which is an interface. Subscription must be on a concrete class type.

After modify sucess do:

    @Subscribe(
            thread = EventThread.NEW_THREAD,
            tags = {@Tag(Constants.EventType.EAT_MORE)}
    )
    public void eatMore(ArrayList<String> foods) {
        Log.i(TAG, "eat: foods => " + foods);
    }

    @Produce(
            thread = EventThread.NEW_THREAD,
            tags = {@Tag(Constants.EventType.EAT_MORE)}
    )
    public ArrayList<String> produceMoreFood() {
        return new ArrayList<>(Arrays.asList("banana", "apple", "egg"));
    }

yes, just like the thrown said: Subscription must be on a concrete class type!
