My commit may still conflict with your logic as it uses pan rather than resize. I'll test and fix this once you're done with your part. Just leaving a note here so it isn't forgotten.

I use android:windowSoftInputMode="adjustResize" for all cases, so there is no need to use setSoftInputMode here.

The reason why I do this is you can use window insets animation only when softInputMode is set to adjustResize.

SOFT_INPUT_ADJUST_PAN doesn't provide seamless animation either. The best way to handle it is using WindowInsets API.

Yeah, I wasn't familiar with this, you're doing a far better job at it than me, thanks!

I used setSoftInputMode to be able to toggle the animation on and off in case anyone wanted the old behavior.
