It's depending the situation set up.
Good: First load the B4a googlemaps in splitscreen, and then load any other app as second. Zoom/rotate works with 2 fingers
False: Load any other app in splitscreen, and then the B4a Googlemaps app. . 2 taps zoom works. 2 fingers zoom not, rotate not. Move works. +/- zoom keys works. So its only a 2 fingers issue
The gmap.GetUiSettings.TiltGesturesEnabled is set to True. (And readback confirms this)
Using version 2.50 google maps api.
On any tablet or phone, all android versions.
Also checked google documentation
https://developers.google.com/maps/documentation/android-sdk/controls: nothing mentioned.
Anyone a suggestion? May be the Googlemaps API should be updated?
