Silencing exception on registered object without onEvent method

I have a BaseActivity class which acts as base for all Android activities in my project.

EventBus.register(this) is done in the BaseActivity without any onEvent methods in it. Some of its subclasses have onEvent and some don’t. I got this exception when starting activities (subclass of BaseActivity) without onEvent methods:

Subscriber class com.example.LoginActivity has no public methods called onEvent  

That’s obviously because LoginActivity has been registered to EventBus in the super class but has no onEvent method. However I could get around this problem by putting empty onEvent in the BaseActivity (a little bit unclean solution)

I suggest that no exception should be thrown in that case (no onEvent methods). Let me know what you think.

Thanks

I think it’d better not to use try-catch here, it’s unnecessary. I prefer provide a value in BaseActivity to indicate if the child need register an event;

public class BaseActivity extends Activity {

    private boolean isNeedRegister = false;

    protected void setNeedRegister() {
        this.isNeedRegister = true;
    }

    @Override
    protected void onResume() {
        super.onResume();
        if (isNeedRegister) {
            EventBus.getDefault().register(this);
        }
    }
}

If ChildActivity need register, just use like this

public class ChildActivity extends BaseActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setNeedRegister();
      ... ...
    }
}

I’ve got same issue while working with activity.

Subscriber class has no public methods called onEvent
