To anyone still looking for this, @javazian's answer of extending each activity is real overkill in my opinion.

A much more succinct solution is to retrieve the nav menu and manually check the relevant menu item.

Note in the example below, INSERT_INDEX_HERE needs to be replaced with the index of the menu item, (e.g. the menu item on the far left would have index 0).

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

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

    // Ensure correct menu item is selected (where the magic happens)
    Menu menu = navigation.getMenu();
    MenuItem menuItem = menu.getItem(INSERT_INDEX_HERE);
    menuItem.setChecked(true);
}
