What tests have you run to determine that the barometer is sufficiently lower power than the GPS radio? I suspect it is, but I have never tried testing the scenario. > Would it be possible to do such a thing? IMHO, not reliably. If you are trying to get altitude accuracy +/- 500 meters or so, perhaps. http://en.wikipedia.org/wiki/Atmospheric_pressure http://en.wikipedia.org/wiki/Altimeter Moreover, none of this has anything to do with Android, and it smacks of premature optimization, unless you have already implemented the GPS-based solution and proven that the power consumption is over your budget. -- 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.
