Answer 1

If your targeted user Api level is 27 or Higher just use this line in your AppTheme

But if your targeted user api level is less 27 and higher you can you these line

By doing so, The user having API level 27 or higher get changed-color of BottomNav icon, but the user having API level less than 27, can't enjoy these feature
