I'm using this technique so that I can show a Composable from a foreground service. Similar to how you would implement chat bubbles or similar floating UI.

It seems to work fine except that I can't my composable doesn't recompose when I update some mutableState that's passed to it. Does anyone know if that's a limitation of using Compose in a foregroundService overlay?

Are you running it from the same process as your main UI?

[jw]

Sounds like you don't have a coroutine which is observing the snapshot change and applying it

[jw]

You might want to try adding this code to run within your service's lifetime: https://github.com/cashapp/molecule/blob/trunk/molecule-runtime/src/commonMain/kotlin/app/cash/molecule/molecule.kt#L189-L198

thanks will give that a shot ❤️

Compose UI will do this for you, normally, but it might be contingent on you showing it within an activity first to kickstart the coroutine

[jw]

I don't remember where it launches this

Compose ui should always bootstrap snapshot observation. If it’s not, that’s a bug.

[jw]

Yeah there's a singleton somewhere

[Colton Idle]

Hm. so maybe a minimal repro would be worth filing?

[Zach Klippenstein (he/him) [MOD]]

Yes please

Were you able to create a repro? Ive been using a similar approach for years and it has worked flawlessly. Might be some minor differences though:
• I use LifecycleService and collect my flows (that update mutableState) inside its lifecycleScope.launch.
• I have a class that extends AbstractComposeView with mutableState properties inside it.
• I use createDisplayContext and createWindowContext for the context that the ComposeView uses (logcat complains otherwise).
I dont know if any of these do anything in terms of compose 🤷🏽‍♂️

I've got a repro yeah. but its in my project. so i just need to consolidate it and post to issuetracker. lol
