Re: Problem simulating a location

[Graham Samuel via use-livecode]

Panos, this is solid gold as far as I’m concerned! I had no idea that 
mobileStartTrackingSensor would return control to the script without finishing 
its job, Wouldn’t it be better, since it isn’t blocking, to provide some sort 
of status token that could be queried by script? Thanks also for the note about 
the bug. I feel I can make progress!

Cheers

Graham

Re: Problem simulating a location

[panagiotis merakos via use-livecode]

Hello Graham,

I have done a couple of tweaks to your code, and I can now successfully
read the location data from the simulator.

First thing - it is not suggested to call all these 3 commands/functions in
one go:

mobileStartTrackingSensor
mobileSensorReading()
mobileStopTrackingSensor

as the "mobileStartTrackingSensor" command takes some time for the sensors
to start tracking. So a good place to add this would be on openCard, or in
a separate button.

Similarly, I have removed the "mobileStopTrackingSensor" from the button
script, and have put it on the closeCard handler (you can but it in a
separate button for your testing if you wish)

So the main button code becomes:

On mouseUp
   put "now trying to get a one-off location reading" & return after fld
"TheReport"
   put mobileSensorReading("location",true) into tSensorData -- this
returns a string with the current latitude, longitude and altitude
   if tSensorData is empty then
  put "no location info!!" & return after fld "TheReport"
   else
  put tSensorData & return after fld "TheReport"
   end if
end mouseUp

However, it seems there is a bug in the function
mobileSensorReading("location",false)

which will be fixed asap

You can workaround this bug by using the "detailed" form of this function,
i.e. mobileSensorReading("location",true)

Note that the "detailed" form returns an array instead of a comma separated
list, so you have to modify the script as follows:

On mouseUp
   put "now trying to get a one-off location reading" & return after fld
"TheReport"
   put mobileSensorReading("location",true) into tSensorData -- this
returns a string with the current latitude, longitude and altitude
   if tSensorData is empty then
  put "no location info!!" & return after fld "TheReport"
   else
  combine tSensorData using return and ":"
  put tSensorData & return after fld "TheReport"
   end if
end mouseUp

Also, in the Simulator menubar, choose a location such as "City Run" or
"Freeway Drive" so as you could see the changes.

Hope this helps.

Kind regards,
Panos

Gents, thank you. Good advice, and I’m taking it! I will report back.

If you have a physical device, regardless of age, try it. There are some things 
that either don’t work (like camera) or are spotty in the emulator.

When you download from the Apple Developer site, just double-click the 
provisioning profile to open it in Xcode. Livecode will know it’s installed 
next time you open the Save As Standalone window (but won’t recognize if you 
install while that window is open)

Re: Problem simulating a location

[Rick Harrison via use-livecode]

Hi Graham,

You should really try it on the phone before knocking yourself out
about why it doesn’t work on the simulator.  I have found that
some things involving sensors simply don’t work on the simulator.

Try that, if it doesn’t work on the phone let us know.

Good luck!

Re: Problem simulating a location

[Graham Samuel via use-livecode]

Folks, I am still struggling with this. Alan Stenhouse has been kind enough to 
help me, but so far I have not got the simulator to simulate any kind of 
location information.

There is a function, mobileCurrentLocation, that is supposed to return an array 
provided tracking is enabled and mobileSensorAvailable(“location”) has been 
invoked (see the LC Dictionary). I have made sure that both these things have  
been done, but In my tests on the simulator the array appears to be empty.

I suppose I can try the test on a real phone, but I would rather stick to the 
simulator for now. And I haven’t found out how LC knows I’ve got a provisioning 
profile (separate problem I admit).

Has anyone got any idea what’s going wrong?

Puzzled.

Re: Problem simulating a location

[Alan Stenhouse via use-livecode]

Hi Graham

IIRC, mobileSensorReading() returns an array so you need to check the keys of 
the array.

Perhaps:

if tSensorData["latitude"] is empty then


HTH
