Steps to reproduce:

  1. Open demo app
  2. On main page click on "LocationSourceDemo" and rapidly rotate the screen (before map gets to be created on next screen, you have to almost simultaneously click on button and rotate the screen)
  3. App crashes with following stack trace:

Have you managed to fix this issue? And if so should I update map kit/hms?

This issue will be resolved in HMS Core APK 5.0.1, the release time is 15th August. We will update the repository at once when the new version is released.
