Error inflating class com.google.android.material.bottomnavigation.BottomNavigationView
Solution 1:
Instead of
app:itemBackground="?colorPrimary"
set
app:itemBackground="@color/colorPrimary"
Edit: also check that the drawables are in res/drawable folder and not in a folder like res/drawable-v21
Solution 2:
Make sure that you put drawables in res/drawable folder and not in res/drawable-v24. I had a similar problem and by moving files to the res/drawable folder the error has gone.
