It is a simple question.
Can I use BottomNavigationView in sdk 22?
I tested with emulator with sdk 22, and it seems to work well.
But, BottomNavigatoinView is released in SDK 25. Does the provide backward compatibility?

I am uncertain where you determined this.
BottomNavigationView is part of the Design Support library, which is being migrated to the Material Components for Android (for when you migrate to AndroidX).
Both implementations work back to API Level 14.
