Tentatively, the annotation should be something use-case-specific like @OutlinedNewApi
that allows alternative build systems (e.g. not R8/D8) to make their own decisions. We'll provide a default Proguard configuration for R8, but it's not guaranteed this will work as intended -- outlining is automatic in newer versions, but it may be disabled.

Just as an FYI, this was enabled in AGP 2 years ago (AGP 7.3 as far as I remember), ag/18426192, so for AGP users it might fine to just remove the rule for @DoNotInline
. I like the @OutlinedNewApi
to make it clear what this is for other consumers to handle it as they see fit.

Given the failure mode can include run-time crashes, that's not an acceptable level of usage.

I think you can still include a top-level proguard.txt
, and it will be used by versions that do not support the com.android.tools
format. E.g.

sonBindViewHolder
of the RV adapter, createComposeView
and add it as a child to theFrameLayout
. CallsetContent
on theComposeView
with arbitrary layout (e.g. coloredBox

Behavior:
What I would expect to happen: No crash happens
What actually happens:
onBindViewHolder
call, theparent
field of theRecyclerView
item view will benull
, but itsmAttachInfo
will not benull
ComposeView
is added to the item view, itsisAttachedToWindow
will be true, and it will try to create a composition.ViewTreeLifecycleOwner
usingView.findViewTreeLifecycleOwner()
which tries walking up the view hierarchy to obtain the owner from the root view.parent
,View.findViewTreeLifecycleOwner()
returns null, andView.createLifecycleAwareWindowRecomposer()
throws and crashes the app.Stack trace (if applicable):
