Hi, I've been playing around a bit with the sdk and the emulator today, and have a question about Location.getSpeed()
I made a small app to test getting speed from the gps. It just prints out the speed as it is received from the gps using a LocationListener and Location.getSpeed() The source code is here: http://pastebin.com/f75e6bfd0 To test it I used the "geo nmea XXX" command in the telnet console. I made a small app that reads a nmea log I created earlier using gpsd when doing a car trip, prepends "geo nmea " to each line and writes them to port 5554 on localhost. The problem is, the speed I get from getSpeed() isn't right, when converting from m/s to km/h I get almost double the speed I really did. Using the same nmea log with "gpsfake" and a linux app that uses gpsd gives me the correct speed. But if I treat the number I get from Location.getSpeed() as knots instead of m/s i get the correct speed in km/h. I tried knots, since many of the nmea sentences that return speed does so in knots. So to me it seems that Location.GetSpeed actually returns the speed in knots, not in m/s as is stated in the documentation. Is this correct, or is there something else wrong? I've only tried this on the emulator, not on an actual handset, since I don't own any phones that run Android. So I dont know if a real handset acts differently from the emulator. I'm using sdk 1.0 r2 on windows and eclipse with the android plugin. --Vegard --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
