I do not know of a way to receive a "signal" from Camera or Microphone.
In Android you use an 'Intent' to call an external app like a camera. See e.g.
in @lib/android.l how to call the camera:
(de takePicture (Dst Fun)
(out Dst)
(startActivityForResult Fun
"android.media.action.IMAGE_CAPTURE"
"output" (fileUri Dst) ) )
A usage example can be found in PilBox in pils/demo/camera.l
(form NIL
(gui '(+Able +Button) '(camera?) "Take Picture"
'(takePicture (tmp "img")
'((Intent)
(setq *Picture (tmp "img"))
(loadUrl (baseHRef) *SesId "demo/camera.l") ) ) )
(----)
(gui '(+Var +Img) '*Picture NIL NIL 400 400) )
Pressing this button calls 'takePicture', and displays the result in the image
component.
The microphone can be accessed with the android.media.AudioRecord class. It
needs an additional permission in PilBox/app/src/main/AndroidManifest.xml
<uses-permission android:name="android.permission.RECORD_AUDIO" />
so you cannot use the pre-built PilBox App, but must build your own one.
