Android Question Capture KeyUP and KeyDOWN for hardware buttons

[yo3ggx]

Is this possible?
I've seen this:

How can this be done in B4A?

Mainly I'm interested to capture camera shutter button and use it as a PTT button.
Thank you.

which device has an hardware camera shutter button?
Sounds for me like you are talking about a button inside the camera app.

Hi.

In my case is a Sony Xperia ZL which has a hardware shutter button for the camera, but there are others too.
I've found the solution.
I just have to define the event
Activity_KeyUp (KeyCode As Int) As Boolean

I was not aware this event exist in B4A.

Thank you.
