I'm trying to debug why remember() creates two different objects. Code inside =>

[reactormonk]

I've got this part of the code invoking the room:

is CallState.InCall -> {
                            Room(url, s.token) {
                                val otherName = otherInfo?.name ?: stringResource(R.string.unknown_caller)
                                PreCall(stringResource(R.string.outgoing_ring), otherName, otherInfo?.imageUrl)
                            }
                        }

fun Room(url: String, token: RoomToken, preCallView: @Composable () -> Unit) {
    DisposableEffect(url, token) {
        Timber.d { "Connecting to room ${token.roomId}" }
        onDispose {
            Timber.d { "Disposing of room ${token.roomId}" }
        }
    }

    val room = rememberLiveKitRoom(
        url = url,
        token = token.token,
        audio = true,
        video = true,
        connect = true,
    )

    Timber.d { "We got room $room" }

The logs:

We got room io.livekit.android.room.Room@62ca600
Connecting to room RoomId(roomId=4d903c87-6e4d-40d3-89c3-d1058ac944bf)

the livekit room:

fun rememberLiveKitRoom(
    url: String? = null,
    token: String? = null,
    audio: Boolean = false,
    video: Boolean = false,
    connect: Boolean = true,
    roomOptions: RoomOptions? = null,
    liveKitOverrides: LiveKitOverrides? = null,
    connectOptions: ConnectOptions? = null,
    onConnected: (suspend CoroutineScope.(Room) -> Unit)? = null,
    onDisconnected: (suspend CoroutineScope.(Room) -> Unit)? = null,
    onError: ((Room, Exception?) -> Unit)? = DEFAULT_ERROR_HANDLER,
    passedRoom: Room? = null,
): Room {
    val context = LocalContext.current
    val room = remember(passedRoom) {
        passedRoom ?: LiveKit.create(
            appContext = context.applicationContext,
            options = roomOptions ?: RoomOptions(),
            overrides = liveKitOverrides ?: LiveKitOverrides(),
        )
    }

[reactormonk]

So that wasn't the issue, but the room object was being reused, which lead to... interesting consequences.

Nope, spoke too soon.

Somehow the old room is still alive?

Something utterly weird, I've got

LaunchedEffect(state) {
                Timber.d { "State is $state" }
            }

But the logs show me:

Directly one after another.

Why isn't compose doing its job here?

[reactormonk]

There should only be one line.

[reactormonk]

huh, nah, it's something else,

lifecycleScope.launch {
            _callState.collect {
                Timber.d { "collect State is $it" }
            }
        }

Also fires twice.

Ah great. Android is creating two Activity even though I told it I want singleInstance
