Yes, I used the hadk to build gstreamer (chapter13.2) and camera (13.3 chapter) but when it said "Install the RPM from$ANDROID_ROOT/droid-local-repo/$DEVICE/droid-camres/onto your de-vice and execute"
I am not sure how to do it.
If I ssh into the phone the 'droid-camres -w' command returns with error.

I thought if I complete chapter 13.2 and 13.3 when I create the final build it will include both things.
However, seemingly the camera is not there as the Mpx in the settings is only showed as a '?'.
