EventBus, is it possible to get the sticky event in the onCreate?

Question

I am sending data from lets say SplashActivity to main activity using EventBus's postSticky method, and depending on that data am creating tabs in MainActivity using ViewPager.

So far it works great and I can setup ViewPager in @Subscribe onEvent(Example data) method.

For Example:

@Subscribe(sticky = true, threadMode = ThreadMode.MAIN)
public void onEvent(Example event){
    mainContentList = event.mainContentList;

    if (mViewPager != null) {
        setupViewPager(mViewPager, mainContentList);
    }

    TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(mViewPager);
}

The issue is arises when we call MainActivity from ActivityC,

Now the @Subscribe onEvent(Example data) would not be called because we are posting to it from SplashActivity only, so it won't be called and the ViewPager doesn't gets updated.

What I want:

I want to get the data from StickyPost as early as possible so I can initialize the ViewPager in the OnCreate method of the activity.

I know I can use Application level Singleton or create a DataHolder class etc to store the data but is there anyway to achieve this using EventBus?

Thanks for your time an if you need any more info let me know and I will update.

The Solution to problem was pretty simple, we can simple. we call getStickyEvent anywhere, something like this

Example:

EventBus eventbus = Bus.getInstance();

ExampleEvent event = eventbus.getStickyEvent(ExampleEvent.class);

    if ( event != null ){

        // Whatever we want to do with event

        // and then we can remove stickyEvent if we don't need it anymore

        eventbus.removeStickyEvent(event);
    }
