selectTab() only callback onTabSelected.

you may check these method:
1.public void selectTab(int newPosition, boolean callListener){ selectTabInternal(newPosition, false, callListener, callListener); }
2. private void selectTabInternal(int newPosition, boolean firstTab, boolean callListener, boolean forcedSelection) { ... if (callListener) { sendListenerCall(oldPosition, newPosition, forcedSelection); } }
3.private void sendListenerCall(int oldPosition, int newPosition, boolean forcedSelection) { if (mTabSelectedListener != null) { if (forcedSelection) { mTabSelectedListener.onTabSelected(newPosition); } else { if (oldPosition == newPosition) { mTabSelectedListener.onTabReselected(newPosition); } else { mTabSelectedListener.onTabSelected(newPosition); if (oldPosition != -1) { mTabSelectedListener.onTabUnselected(oldPosition); } } } } }

selectTab(xxx,true) call sendListenerCall(xxx,xxx,true), that only callback
onTabSelected
selectTab(xxx,false) cannot access sendListenerCall().only if call sendListenerCall(xx,xx,false) that callback onTabSelected, onTabUnselected, onTabReselected.

you seems to not figure out my last issues,

and i reccommend override onSaveInstanceState and onRestoreInstanceState to save some state like currentposition for restore from killed background

you may add this method in BottomNavigationBar.java
public void selectTab(int newPosition, boolean callListener, boolean forcedSelection) {
selectTabInternal(newPosition, false, callListener, forcedSelection);
}

and call this method selectTab(position,true,false);
