Hey does anyone has workaround for this Preview error ```The following classes could not be instantiated androidx compose ui tooling ComposeViewAdapter Open Class Show Exception Clear Cache Tip Use View isInEditMode in your custom views to skip code or show sample data when shown in the IDE If this is an unexpected error you can also try to build the project then manually refresh the layout Exception Details java lang ClassNotFoundException androidx customview poolingcontainer R$id``` It happened to me after updating compose to `1 2 0 alpha06` It doesn t work both on Chipmunk and Dolphin

I can t even remember when the Preview did work for me maybe on Compose 1 0 beta thinking face Every time I try it new compose or AS versions I get some error I gave up on Compose Preview months ago confused

Maciej Czekański · Answer

it does work for me on Google s sample compose apps but I couldn t figure out the differences in the setup So far I gave up and I m waiting for the next release

This is likely caused by this breaking change <https kotlinlang slack com archives CRDCFF3RC p1648713073485449 thread ts=1648572322 195129 amp channel=CRDCFF3RC amp message ts=1648713073 485449|https kotlinlang slack com archives CRDCFF3RC p1648713073485449 thread ts=1648572322 195129 amp channel=CRDCFF3RC amp message ts=1648713073 485449>

I figured it out I ll let you know later

Maciej Czekański · Answer

Try adding `androidx customview customview poolingcontainer 1 0 0 alpha01` dependency

Filip Wiesner · Answer

Holy shit I was about to say that it should not make a difference because that dependency should already be on path but it worked open mouth Thank you

Maciej Czekański · Answer

I spent probably a few hours on that since alpha06 disappointed

Chris Sinco [G] · Answer

We are working to on a fix to prevent folks needing to add that transitive dependency explicitly for Preview but still working on it

Is there any update to this issue Still seems to be happening on `1 2 0 alpha08` thinking face

Chris Sinco [G] · Answer

What version of Studio are you using And is this still happening for you on beta01+

Tash · Answer

Seeing the issue on 2021 1 1 Patch 3 amp 2021 2 1 Trying on 2021 3 1 Beta 1 Haven t tried Compose beta yet

Chris Sinco [G] · Answer

Do you have a code snippet handy to help repro on my side

Tash · Answer

Working on a minimal repro project

Tash · Answer

Minimal repro this happens when using previews in an android library module + `1 2 0 alpha08` + `Kotlin 1 6 20` Looks to be this issue <https issuetracker google com issues 227767363> and adding ```debugImplementation androidx customview customview 1 2 0 alpha01 debugImplementation androidx customview customview poolingcontainer 1 0 0 beta01 ``` seems to get rid of it wondering if there s an alternative though

Tash · Answer

Update seems to be working on the latest Dolphin 2021 3 1 Beta 1 without workaround

Chris Sinco [G] · Answer

Yeah it s a Studio issue and shouldn t require adding more dependencies that is it s not a library issue per se It should be fixed in Dolphin beta which looks like you ve found that it does relieved
