Share My Creation GPService 2.0 (.apk)

Hello all!
Today another application that I would like to share - GPService 2.0

Classically uses a GPS signal to determine your location.
During operation, the information is saved to * .GPX files,
- After getting the exact position (fix accuracy up to 100 meters) you can go
to external application OsmAnd +.
- the last fix is stored in the file (settings.dat)

Sub Service_Start (StartingIntent As Intent)
    Try
        UpdateStatus (True, True)
        StartServiceAt("", DateTime.Now + 15 * 1000, True) 'will start after 15 seconds.
        'S e r v i c e Turning GPS ON
        GPS1.Start(0, 0) 'Listen to GPS with no filters.
     Catch
        '_ERROR Notification("E R R O R" & CRLF & LastException.Message)
        CancelScheduledService(Service)
    End Try
End Sub
