[racket] request for testing Moby geolocation on android phone

Hi everyone,

I'm trying to see if the geolocation code I'm using for Moby (my
Racket->Android compiler) is robust across different Android
smartphones.  If you're interested, can you run the following program
on your Android phone and let me know if it runs well?  It's a simple
world program that displays the current latitude/longitude, compiled
with my development version of Moby:

    http://hashcollision.org/tmp/loc.apk

The source is below:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
#lang planet dyoo/moby
(require (planet dyoo/moby/phone/location))
(define (update w lat lng)
  (list lat lng))
(big-bang "loading"
          (on-location-change update 10))  ;; request geolocation
update every ten seconds
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

If you can get back to me by tonight about this, I'd greatly
appreciate it.  Thanks!
