Re: [android-developers] Best way to live demo apps

Thanks DroidAtScreen seems to work OK, if a little slow. I can work
with that for now. (Thanks!) The OP solution is good but also won't
work for me. HDMI will be great once its available and supports
outputting the device's screen.

The hardware clearly supports streaming full audio and video (since
you can record video from the camera). However, the Android SDK's
VideoSource class only supports capturing from the camera. If there
are no plans to make video recording available any time soon I might
(if I have time) try hooking up ffmpeg through the NDK. This might get
me full speed video for my application (since I can provide it a
buffer containing an Activity's root View).

Does anyone know if its possible to access to the root View of the
current Activity (of existing apps, without code changes)? There are
applications such as Display Shot that seem to overlay images on top
of whatever is running (without rooting the phone), so I'd guess its
possible, but I can't find how.

Aside, from big screen display, the other thing this could allow is
remote desktop access into the device, which has a ton of development
uses.

Cheers,
