Though I am not an Android developer, I can think of a way around this... Provide a special "calibration" mode. The user could enter the calibration mode, point the camera at a gray card under sunny-16 (or sunny-11) conditions and hit a button. This could then be stored as a setting for the app on the phone. Presto... Calibration complete - at least in the linear response range for the camera.
