I'm new to Android/AR development, and this toolkit looks pretty cool.
I was playing around with the VirtualButtons sample, and wanted to extend it by turning my device's (Nexus 1) built-in led-flash onto Torch mode to help in low-lighting conditions.
After a bit of playing around, I've managed to get the flash to turn on before the JNI call to startCamera(), but if i don't release the camera instance, the native camera interface can't access the camera (i'm guessing), so nothing displays on screen. If i release the camera instance, the light turns off :/
Digging into the native side of things, it looks like the QCAR::CameraDevice, doesn't expose this functionality at all.
Any suggestions on how one could do this?
