Upgrade your androidx.compose.ui:ui-tooling to 1.0.0-rc02 too

[Shakil Karim]

Yeah already did that still the same issue.

[George Kylafas]

Forgive me for insisting, but is there a chance that specifically ui-tooling is still hardcoded to e.g. 1.0.0-beta09 and doesn't use 1.0.0-rc02?
Is that's not the case, then maybe a clean & rebuild of the project will help.

[Shakil Karim]

@George Kylafas Yeah I just recheck it's 1.0.0-rc02 and also clean rebuild still no luck 😞

[George Kylafas]

If it's any consolation, at some point I started getting androidx.compose.ui.tooling.PreviewActivity is not an Activity subclass or alias errors.
Note 1: AS 2020.3.1 RC1, Compose 1.0.0-rc02
Note 2: Our error messages are different, yours has an extra .preview

[Shakil Karim]

Did you manage to resolve this issue?

[George Kylafas]

No, I still get the same error... Did you have any luck?

[George Kylafas]

I was trying to deploy Composables with AS's gutter icon to the left, or the respective keyboard shortcut (Ctrl-Shift-F10 for me) with no luck.
But then I tried with the deploy icon in the preview pane and it worked. 🤦‍♂️ Previews also started getting rendered correctly too.
I don't know what's the different but at least it worked.

[Shakil Karim]

Yeah, preview in AS is working for me as well but deploying preview Composable is not on latest Canary as well as on RC.

[George Kylafas]

I noticed that preview deploy works when deploying to an API 30 image
