Improve MarkerView flick behavior #1165

Closed OttyLab closed 3 years ago

OttyLab commented 4 years ago

Background

MarkerView position is only updated withonCameraDidChange. When a user flicks the map, MarkerView keeps the position until the flick animation is finished as below. This behavior looks laggy from user point of view. before

Update

Call update() in onCameraIsChanging as well.

Result

after

@Chaoba Thanks! Sure, I'll do the test. BTW, do you have any metrics about performance? If no, then I'll just check if I can see a laggy behavior on some Android physical devices (Nexus 5 and Pixel 4a would be candidates)

Chaoba commented 4 years ago

@OttyLab AFAIK, we don't have any metrics for makerview.
Yes, please check on your device.

@Chaoba Here's the result of physical device test. If the device is not powerful, this update makes the animation a bit laggy. But it's not critical, I suppose.
