Question

I am working on a simple application that I need to be run as a service and report gps position every 3 minutes. I already have a working example based on the tutorial, but still have the followin doubts.

  1. The starting of the service GPS1.Start(5*60*1000, 0) Says first parameter is time lapse, and 2nd parameter is distance difference, How is determined, based on prior position ?

  2. If I want to do what I stated before and I am scheduling / starting service every 3 minutes, this means I will need to ask a GPS1.Start(0,0) to get latest fix? what would be the gain to use the parameters?

  3. I trying in a NexusOne and the Time object comes with local time, I have to do this to make it UTC but this is a tweak to the code. Is this a standard or could It change based on Phone model ? hora=DateTime.Date(Location1.Time + 6*DateTime.TicksPerHour)

thanks

Was it helpful?

Solution

If you are only interested in a single fix each time then you should pass 0, 0. These values affect the frequency of subsequent events.

You can find the time zone with the code posted here: GetTimeZone
