Over a period of few minutes, you can. The XOOM was the first device with a barometer IIRC, and I definitely recall presentations by (now former) MOTODEV staff discussing tests they ran using parking garages, and how the XOOM nailed the height change fairly well. Over a period of hours or longer, though -- such as what the OP's trying to do -- you are spot on. Weather will have a substantial impact on barometric pressure. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy In questi siti web puoi chiedere o rispondere a domande relative allo sviluppo di applicazioni Android: http://www.andglobe.com -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
