Camera stopped during a cancellation

[mcfboss]

Hello,

I have a map in a Box where it has some BottomSheet like composables on top that appear from the bottom when you click on some of the markers, kind of google maps style. The problem comes when I flick the map and before the camera stops moving I click anywhere in the map to stop moving it, then I get this exception :

com.google.maps.api.android.lib6.common.apiexception.c: Camera stopped during a cancellation

I thought it was related to having composables on top, but the problem is still there if I remove them. The problem is only occuring with fast camera movements and suddenly stopping them clicking the map or some marker.

Any ideas what could it be? Thank you!

I'm not able to repro this in the sample app. Can you share a snippet of your implementation?

Hello Unfortunately, I can't share a minimal example, but I can add data.

Hello! I think this error is caused by a CancellationException that did not reach the parent scope probably because it was caught in a try-catch block. This is an error that revolves around exception handling with coroutines.

Stopping the animation cancels the coroutine and throws a CancellationException. This cancellation exception should be rethrown.

try {
  scope.animate(CameraUpdateFactory.zoomIn())
} catch (e: Exception){
  if (e is CancellationException) throw e
  // catch other errors here
}

Hope this helps!

Hi @arriolac I'm running into the same issue, for me happens when I have minify enabled and when trying to use cameraPositionState.animate. The map target won't move and when I try to move it manually the exception is thrown.

If I disable minify the crash doesn't happen. Are there proguard rules we need to use?
