I noticed that in Android 2.2 and earlier I must do either a FULL_WAKE_LOCK or a combination of PARTIAL_WAKE_LOCK and FLAG_KEEP_SCREEN_ON to make sure the camera does not get turned off after a while with my app in the foreground (and I need a wake lock to keep GPS going). The underlying assumption seems to be that the camera is not useful when the screen is off, but that assumption is false for computer vision applications where not the user but the program is watching the camera view. Is this fixed in Android 2.3 (Gingerbread)?
