This is my Subscriber from MainActivity.

@Subscribe(sticky = true )
    public void eventMessage(YuriActionMessage message){
        if (message.getAction() == "LOAD_PLAYER_UI") {
            load_ExoPlayerUI();
        } else if (message.getAction() == "LOAD_PLAYER_UI_PLAYPAUSE") {
            load_PlayPauseBtn();
        } else if (message.getAction() == "SET_CURRENT_VIEWPAGER_ITEM_DETAILFRAG") {
            mact_IzoneVIewPager.setCurrentItem(5);
            //EventBus.getDefault().removeStickyEvent(true);
        } else if (message.getAction() == "SET_CURRENT_VIEWPAGER_ITEM_ALBUMFRAG") {
            mact_IzoneVIewPager.setCurrentItem(1);
            //EventBus.getDefault().removeStickyEvent(true);
This is the postEvent in my Fragment Attatch from MainActivity
public void initTrackModelList(long albumid){
        IzoneGetTracksByAlbum izoneGetTracksByAlbum=new IzoneGetTracksByAlbum(this.getActivity(),albumid){
            @Override
            protected void onPostExecute(String s) {
                super.onPostExecute(s);
                initRecyclerView();
                EventBus.getDefault().postSticky(new YuriActionMessage("SET_CURRENT_VIEWPAGER_ITEM_DETAILFRAG"));
        izoneGetTracksByAlbum.execute(mTrackModel);
this is my Event Message Model.
public class YuriActionMessage {
    private String Action;
    public YuriActionMessage(String action){
        this.Action=action;
    public String getAction() {
        return Action;
    public void setAction(String action) {
        Action = action;
It's not about Eventbus. Sometimes errors in your code are thrown as Eventbus exceptions. Check your code. For example:
 mact_IzoneVIewPager.setCurrentItem(5);
