如何获得 Android 设备的最准确高度

Question

I am coding a Fitness tracking App right now. Therefore I want to use the Altitude. I know I can get the Altitude via GPS, but this seems far away from being accurate. I already tried my app on several devices and all of them had problems with their altitude. Thanks for your help.

There seems to be a google maps api, Google Maps Elevation API, which seems to provide the data you need, but apparently it does need a billing account associated, not sure if thats a possibility. But I would expect a company like Strava to use something like this, it seems pretty legit and accurate.

You make request:

https://maps.googleapis.com/maps/api/elevation/json?locations=39.7391536,-104.9847034&key=YOUR_API_KEY

and get something like this JSON back:

{
   "results" : [
      {
         "elevation" : 1608.637939453125,
         "location" : {
            "lat" : 39.73915360,
            "lng" : -104.98470340
         },
         "resolution" : 4.771975994110107
      }
   ],
   "status" : "OK"
}
