MakeBadgeForTabAt() throws a MethodNotFoundException when used on a device with API 22 or lower

[nextmunich]

The method SetTextAppearance(int resId) used in BottomBarBadge's constructor has only been introduced in API level 23, leading to a MethodNotFoundException when constructing a new instance on a device running API level 22 or lower.

Exception:
