LiveCode Forums.

Hi all,

I've got my gps app working with LiveCode 4.6.4.
I had to use Basic4Android to generate my GPS coordinates since LC 4.6.4 couldn't.

Now that LC 5.5 for Android has GSP capability,
I can't seem to find a practicle example of its use.

Does anyone have a working GPS sample app for Andoird?

I'm gonna stumble me way thus this lesson n see what trouble I can find on Android:
How do I use Core Location in revMobile
http://lessons.runrev.com/s/lessons/m/4 ... -revmobile

Just change any iOSxxx command to mobilexxx.
And iPhonexxxx to mobilexxxx.

My tests took about 30 secs to 2.5 mins to get the GPS reading.
(See next message to improve GPS response.)


16. The permissions to be added to the manifest.
i. Write external storage is required if your app will read or write files on external storage
(e.g. an SD card)
ii. Internet is required if your app is accessing the internet.
iii. Camera is required if your app is using any camera features.
iv. In-App Billing is required if you wish to use In-App purchasing
v. Fine Location is required if you wish to use GPS to triangulate device location (requires
course location)
vi. Coarse location is required if you wish to use mobile networks to triangulate device
location

As an additional note I have confirmed that the GPS Tracking automatically stops when I exit my GPS test app.

Make sure Settings | Wireless & Networks | Wi-Fi is Connected (ticked on)

Settings | Location & Security Settings | Use wireless networks (ticked on)
Settings | Location & Security Settings | Use GPS satellites (ticked on)

I'm wondering is there a way for LiveCode for Android to check these three settings?

Another GPS sample using the LC browser.

Instead of retrieving a static map from google like the TickedOn project.

Lots of nice reminders how well rounded LiveCode is.
(Well if one knows how to use it properly that is. Meaning not me. )
Orientations, ControlCreate, mobileControlSet, Environment, resizeStack, etc.
Very nice.
Thanks Dixie.

Genius!

Are you just interested in a simple example of how LC 5.5 can be used to return Lat and Lon coordinates? I have a stack that I have been playing with more for fun than anything else. It came out of an idea for racing sailboats, where the app automatically detects the time you pass over the start line (between to GPS coordinates). It has the basics of grabbing the Lat/Lon coordinates and some basic trig to process the ouput. I'll post it if this sounds like something that would help, but I think the L/C code is probably pretty crude.

I have a more advanced app I'm working on to lay out a race course using GPS, but the GPS stuff is pretty much buried in the complexities of the rest of the program.

Yes please Gene.
Anything you would care to post would be fantastic.
