Not sure if this question really fits in here but here it goes.
As Linux kernel is running under Android, how would one write applications that would run native (without Java overhead)? Additionally to the first question, I would like to access camera in that arrangement, like one would for example use v4l2 on PC or similarly?

Thanks,
Damjan

It really depends on the camera and the kernel the device is running.

If kernel > 2.6.26 (which it should be, as Android 1.5 was using 2.6.27 already) and your camera is supported by UVC, then it's easy (V4L being the best choice). Otherwise, you will need the source and/or binary SDK, which is usually quite difficult to get ahold of.
