NullPointerException java.nio.ByteBufferAsIntBuffer in put

[mbarakacart]

Environment details

happening with Android 8, 9, 10, 11, 12 I believe it started at 2.7.2, but right now I have 2.8.0

Steps to reproduce

Unfortunately I was able to do it only once, it happened when I scrolled down programmatically in LazyColumn using scrollState.animateScrollToItem(), which cause the map to disappear. I am not sure if the map was trying to move camera at that time or not though.

Code example

LazyColumn () {
 GoogleMapRow(mapViewState)
}
@Composable
fun GoogleMapRow(mapViewState) {
  val mapProperties = remember(mapViewState) { mutableStateOf(MapProperties(......) } 
  val mapUiSettings = remember(mapViewState) { mutableStateOf(MapUiSettings(......) } 
  val mapOptions = remember(mapViewState) { mutableStateOf(GoogleMapOptions(......) } 
  val isMapLoaded = remember(mapViewState) { mutableStateOf(false) } 

  GoogleMap(
  Modifier.defaultMinSize(minWidth = 50.dp, minHeight = 30.dp), 
  cameraPositionState,
  mapProperties, mapUiSettings,
  googleMapOptionsFactory = { mapOptions },
 onMapLoaded = { isMapLoaded.value = true },
) {
  // loop on Marker list
}
 
 LaunchedEffect(key1 = isMapLoaded.value) {
     // cameraPositionState.move(update)
    // cameraPositionState.animated(update, 1000)
  }
}

• Is there any issue remembering those properties?
• I also remember the marker bitmapDescriptor, for the marker, can this cause an issue?
• I also tried to disable the LaunchedEffect is the MapRow is not visible anymore using LazyListState.layoutInfo.visibleItemsInfo and looking for the row key

I'm also seeing the same unhandled exception crash. I believe it matches the following issue in Google's public issue tracker is relevant: https://issuetracker.google.com/issues/237380999?pli=1, which is marked as 'fixed'

I believe you are right, we tested using the new renderer for a while and we saw improvement, but unfortunately we started seeing another issue where the MapMarker are breaking and found a Google issue here.

This current issue however seems to be happening with Compose + GMap (we have the compose map in LazyColumn). While the Marker issue is happening with non compose map + new renderer.

Started to get the same issue in our compose map screen in a lazy column as well
