I am currently working on an Android library which helps create a floating view on the screen. 
Recently, I added support for Composable and with the help of a custom LifecycleOwner, I can show/remove composable without any issue. 
However, when scrolling through the LazyColumn/Row/etc, if I call removeView before the animation stops, the app start crashing. 
this is the error message “Cannot start this animator on a detached view!”. 
I stuck in this issue the whole day, sorry if i bother you guys :cry: . Thank you
I also asked on stackoverflow, you can see more detail there <https://stackoverflow.com/questions/75788922/jetpack-compose-with-windowmanager-cannot-start-this-animator-on-a-detached-vi|https://stackoverflow.com/questions/75788922/jetpack-compose-with-windowmanager-cannot-start-this-animator-on-a-detached-vi>

Throwing some ideas: have you tried stopping the animation or scrolling before removing the view?

Why are you only stopping the Lifecycle instead of actually moving it to DESTROYED and triggering the disposal of the composition?

That worked! After calling “destroyed” when removing the view, the issue is now gone, thank you for pointing me out :heart:
