Our client doesn't want it's employees to use 2 devices at the same time (double costs etc.).
Is it possible to run the apk in a emulator with all functionalities (GPS / Phone / Camera)?
Or is it possible to convert the B4A-app to B4J and then run on a Windows 10 tablet?
Does it run full Windows? If so then you can use B4J to develop apps for it. However it will not be trivial to integrate with the hardware features mentioned above.
