Note that in PilBox you can also directly call the standard Android API, and use the REPL of course.

Taking a picture, for example, needs only

   (android~takePicture (tmp "img")
      '((Intent)
         (... do something with the image) ) )

The function 'takePicture' is in "lib/android.l":

   (de takePicture (Dst Fun)
      (startActivityForResult Fun
         "android.media.action.IMAGE_CAPTURE"
         "output" (fileUri Dst) ) )
