To completely remove animations:

If you also want to get rid of that annoying little top margin animation, you need more reflection code. Here's the complete solution that removes any animation:

@SuppressLint("RestrictedApi")
private static void disableShiftMode(BottomNavigationView view) {
    BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
    try {
        Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
        shiftingMode.setAccessible(true);
        shiftingMode.setBoolean(menuView, false);
        shiftingMode.setAccessible(false);
        for (int i = 0; i < menuView.getChildCount(); i++) {
            BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
            item.setShiftingMode(false);

            Field shiftAmount = item.getClass().getDeclaredField("mShiftAmount");
            shiftAmount.setAccessible(true);
            shiftAmount.setInt(item, 0);
            shiftAmount.setAccessible(false);

            item.setChecked(item.getItemData().isChecked());
        }
    } catch (NoSuchFieldException e) {
        Timber.e(e, "Unable to get fields");
    } catch (IllegalAccessException e) {
        Timber.e(e, "Unable to change values");
    }
}

And make sure to add that to your proguard configuration file:

-keepclassmembers class android.support.design.internal.BottomNavigationMenuView { 
    boolean mShiftingMode; 
}
-keepclassmembers class android.support.design.internal.BottomNavigationItemView { 
    int mShiftAmount;
}
