I'm testing with the pocketcasts app: https://github.com/Automattic/pocket-casts-android

Most of the previews are rendering well -- but there are quite a few that don't. The render error UI makes it clear that there are cases where this is expected -- e.g. your view model code may be calling into Android APIs that aren't part of layoutlib.

However, I suspect that is not the case here -- there are a lot of previews that have been built and checked into the source code repository. So I suspect maybe they worked at some point. And Diego mentioned he has been testing this same repository and hasn't seen it, so I thought I'd best to file a bug with the specifics.

Example 1: OnboardingCreateAccountPage, OnboardingForgotPasswordPage, SwipeableStars

failed to load view models: java.lang.NoSuchMethodException: au.com.shiftyjelly.pocketcasts.account.viewmodel.OnboardingCreateAccountViewModel.<init>()
	at java.base/java.lang.Class.getConstructor0(Unknown Source)
	at java.base/java.lang.Class.getDeclaredConstructor(Unknown Source)
	at androidx.lifecycle.ViewModelProvider$NewInstanceFactory.create(ViewModelProvider.kt:199)

Example 2: StoryTopFivePodcastsView, ShareListCreateBuildingPage

java.lang.UnsupportedOperationException: getApplicationInfo not implemented in subclass   at android.content.pm.PackageManager.getApplicationInfo(PackageManager.java:5698)   at au.com.shiftyjelly.pocketcasts.utils.Util.appInfoHasBoolean(Util.kt:52)

(This one looks like a legitimate limitation -- the code has a utility method calling into the package manager. But *if* this is a method stubbed by layoutlib (the unsupported operation exception) maybe this is a scenario we can consider special casing?

Example 3: SearchHistoryPage

java.lang.IllegalArgumentException: Required value was null.   at au.com.shiftyjelly.pocketcasts.search.searchhistory.SearchHistoryPageKt$SearchHistoryView$1$2.invoke(SearchHistoryPage.kt:129)   at au.com.shiftyjelly.pocketcasts.search.searchhistory.SearchHistoryPageKt$SearchHistoryView$1$2.invoke(SearchHistoryPage.kt:127)   at

Example 4: AboutFragment

android.content.res.Resources$NotFoundException: Could not find styleable resource matching value 0x0 (resolved name: Window_backgroundDimAmount) in current configuration.   at android.content.res.Resources_Delegate.throwException(Resources_Delegate.java:1156)   at android.content.res.Resources_Delegate.throwException(Resources_Delegate.java:1132)   at android.content.res.Resources_Delegate.throwException(Resources_Delegate.java:1136)

Note: I'm pretty sure I saw this problem when using the pocketcasts project directly without modifications -- at least the ones on the onboarding pages. Since then I've upgraded the project to have newer versions of everything (agp, compose, etc). That's what I was using when I generated the above. I've attached my patch.
