onCameraChange is not always called for the final position in the animation

[altafrm3d]

Steps to trigger behavior

onCameraChange i am calculating the Zoom level of Raster Tiles (using Math.round(cameraPosition.zoom)) and labeling it as shown

Expected behavior

onCameraChange is always called for the final position in the animation, so in my case, it should always update the label when the camera change is completed and the tiles are updated

Actual behavior

onCameraChange is not always called for the final position in the animation, but it misses a frequent number of times as shown in the gif

@altafrm3d thank you adding a gif to explain the issue, could you add the version where you are having this issue?

@tobrun I am not sure what you meant by the version, this is the last commit in the logs, maybe that is already enough for you

[build] bump mason to update Android compile flags

[tobrun]

Thank for confirming that you are building from master. Note that you can also use stable versions that will not have this issue or build from the release branch release-android-v4.2.0. I changed the invalidation recently in #6532 to not refresh the camera position too much, it seems that gestures aren't always covert. I'm going to patch this up by hooking into setGestureInProgress(false) to determine if we need to notify OnCameraChangeListener for a change.
