Hi I have ported the similar V4L2 stuff to android2.2 on beagle board , it builds for me but when I click on Camera application it says please insert the SD card . Are there any vold issues in android2.2 ? I guess the media scanner or vold some how unable to detect/mount the SD card such that the camera application was not aware of SD card.
please find me some pointers on this. Thanks & Regards, Venkat.
