I just checked this approach out as a user had emailed me asking about
screenshot capability. This definitely does the trick, but a another poster
pointed out, any output from certain components (in my case the camera
preview surfaceview) does not show up.
Perhaps the correct approach then is to capture the output of the surface
views as bitmaps, and then draw on top of them, it's not quite an "instant"
screenshot, but will probably serve the purpose? I'll experiment with this
and if I have good results will post back.
Mark Murphy, you said this is impossible, did you mean in the sense of the
way DDMS grabs the full-monty screenshot?
I do hope that Android Handset/Tablet manufacturers catch on and implement
hardware screen capturing options, a la iOS -- I don't believe screenshots
are programmatically possible there either, for the same reasons, but the
user can capture one at any time with a combination of hardware buttons. It
will prevent us from having to come up with adhoc solutions like this, and
allow the screenshot process to be user driven, and thus alleviating
security concerns. I believe I read that either Samsung or Motorola may do
this in future handsets?
