I would just add, if you wanted to use your BottomNavigationView.OnNavigationItemSelectedListener()to select your start fragment you can use the setSelectedItemId() e.g. :

Replace 'R.id.navigation_home' with your own start fragment.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    BottomNavigationView navigation = (BottomNavigationView) 
    findViewById(R.id.navigation);
    navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
    navigation.setSelectedItemId(R.id.navigation_home);
}
