Description

I'm using a CircleManager to handle a bunch of events such as click, long click, drag started, drag and drag finished. I am also using some android animations that do things such as periodically change the circles' radius.

Without the animations the drag events work just fine.

Now, with the animation process on, I can't drag my circles around.
Using some traces I realized that the onAnnotationDragStarted event does get triggered when I try to move a circle. However, the onAnnotationDragFinished also instantly gets triggered right after the onAnnotationDragStarted.

Am I doing something work or is this expected behaviour ? If so, is there any workaround for it ? I'd very much like to be able to both animate and drag around my annotations.

Thank you

Research direction

Start by reproducing the issue with CircleManager, draggable circles, and the Android animation that changes their radius. Trace the drag-started and drag-finished callbacks while animation is active; done means annotations can be animated and dragged without drag finishing immediately.
