Bug? Take Screenshot

Pendrush · Jan 11, 2019

In last few version of B4A I'm not able to take screenshot from B4A it self.
When I click on Take Picture in menu, I can see busy pointer and after approx 2 sec pointer return to normal state, with no image and no error. Tested on Nexus 5 Phone, Samsung Note 5 and on Genymotion emulator.
As workaround I'm using Android Monitor from SDK folder (\sdk\tools\monitor.bat).

Unfiltered log from genymotion emulator:

The image is created on device on path: /storage/emulated/0/b4a_screenshot.png but is not transferred to B4A.

EDIT:
I'm using USB for connection between device and PC.

EDIT 2:
Android version don't play any role, tried on v5.0 - v9.0, same behavior on all versions.

What happens with a real device?

On Nexus 5, today screenshot is taken and transferred as it should in B4A. Nothing changed.
Still don't work from Genymotion.

Nexus 5 unfiltered log:

This tool works with real devices. It is very simple to take screenshots of emulators or VMs.
