Hello,

For some reason my code is no longer working, it doesn't seem to be tracking the location and therefore is not able to do anything on location changed. I wonder if it is an issue with my code? Or could it be in the xcode simulator or the properties?

Heres the Start button script:

Code: Select all

global counterVar
on mouseUp
   put 0 into counterVar
   mobileStartTrackingSensor "location"
end mouseUp

and the card script:

Code: Select all

on locationChanged pLatitude, pLongitude, pAltitude
   
   put pAltitude & cr after field "altitude"
   put pLatitude & cr after field "latitude"
   put pLongitude & cr after field "longitude"
   put counterVar into field "counter"
   add 1 to counterVar
   
   put the short date && the short time into field "dateTest"
end locationChanged  pLatitude, pLongitude, pAltitude

Thanks!

Hi calmrr3 - can you give us information on which versions of OS X, LiveCode and Xcode you are running?

Posted: **Wed Jan 21, 2015 2:25 pm**

OS X Version 10.9.5
Livecode Version 7.0.1
xCode Version 6.1.1

This was working but now it isn't and I can't see any reason why.

Thanks

Hi calmrr3,
Yeah, I found something odd with Debug > Location as it wasn't sending out a change until I changed it to another method.

I am experiencing this too, preOpenStack or openStack does not seem to start the mobileTrackingSensor. If i put it in the default/first card's preOpenCard or openCard it doesn't work either, however if i put it in another card's preOpen it does work.

Using:
OS X 10.10
xCode 6.1.1
LC 7.0.1 and 7.0.2 (rc1)

iOS 8.1
Android 4.4.2
(both mobile OS not work)

Code: Select all

on initMobile
   if the environment is "mobile" then
      if mobileCanTrackLocation() is true then
         mobileStartTrackingLocation
         //mobileStartTrackingSensor "location", false
      else
         answer "Can't find your location"
      end if
   end if
end initMobile

The above is called from the preOpenXXXX.

Maybe it's the same problem as in this thread: http://forums.livecode.com/viewtopic.php?f=49&t=22367? If so it got fixed in 6.7.2RC2, see bug report http://quality.runrev.com/show_bug.cgi?id=14290

Thanks Chris, you prompted me to double check, I can confirm it is working fine now in both 6.7.2 and 7.0.2. I tested in 6.7.2 with a new clean stack and it worked a treat, but then opening my existing project in 7.0.2 it no longer worked. I shuffled things around in the preOpenStack putting my initMobile call first and moving all variable declares to the top (out of handlers) and it now works ... hmm.
