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.

It damned well better not be, at least without root. 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. I can't comment on that, other than to say it's a security hole to allow arbitrary on-device code to access the contents of the screen. 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. Which also would require root access or firmware mods, as there is no way for ordinary applications to inject events to arbitrary applications -- again, for security reasons. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Warescription: Three Android Books, Plus Updates, One Low Price! -- You received this message because you are subscribed to the Google Groups Android Developers group.

RE: [android-developers] Best way to live demo apps
Yeah, I'd sort of thought that too, but thought that maybe a little out-of-the-box thinking might serve as a good solution instead of heading down a yak-shaving exercise that turned out to be more fragile than useful. (I've been there, done that. :-) ) Meanwhile, I'll bite: why is it called the ELMO?
