Is it possible to prevent an AndroidView from recomposing if a parent node recomposes? I have an AndroidView wrapping a camera2 PreviewView to display the camera feed. When a parent node recomposes I see that the PreviewView blinks black, which tells me that the view is being recreated.

Just spit-balling here, but you might be able to wrap the composable definition in a key(x){} where x is something contextual, or unit 😬

can you show your code? generally recomposing an

AndroidView

composable does not recreate the view. There may be something else going on there.

@Adam Powell I was lazy. I only read the doc for the

update

param which says "The callback to be invoked after the layout is inflated.", so I thought it was an adequate place to set the preview surface. Reading the docs for

AndroidView

a bit further I found "The 

update

 block can be run multiple times (on the UI thread as well) due to recomposition, and it is the right place to set 

View

 properties depending on state". Then I realized what was my mistake, and I moved everything to

factory

. I guess the doc for

update

should be changed to something like

the callback to update the view when there is a recomposition

. Should I create a PR to update the docs?

Since this led to some confusion for you I think it's important that the docs are especially precise here. The

update

block will be run if: 1. the view is initially created by the supplied factory 2. a new

update

is provided through recomposition (e.g. recomposed with a new/different lambda capture) 3. snapshot state accessed by

update

was invalidated

Thanks @Adam Powell
