Google Maps on a server

[nosaj66au]

Hi Guys, I'm already a B4A payed up developer and I'm looking for some sugestions. I need to have a number of phones reporting position back over the internet, to a central server and have all positions displaying it on a Google Maps ?

Any Idea on a neat solution?:sign0085:

You can use HttpUtils together with the GPS library to send the location to a web server which will store the location and time in a database.

Another application / script can read the locations from the database and show it on a map.

Thanks Erel, I have had a look at "Google Latitude" for Android and it looks just like I'm after, however I would like the client within a B4A App. It seems to be manipulated via an API simlar to the Google Map Api and uses JSON, which todate I have never used.
Is there anyone out there that could take a quick look at the Google Latitude API and see if what I'm proposing is practical before I lanch myself into a whole new learning curve?

Thanks Heaps
Jason

It looks feasible. You can build a solution similar to the one discussed here: http://www.b4x.com/forum/basic4android-updates-questions/11925-how-import-google-contacts-info.html

On this website you can find some good example code for the server side:

Have a look at "Markers from a text file" and "Markers, infowindow and sidebar contents from a text file"

Be aware that commercial use of the Google Maps API is not free!

Thanks Again Guys. I'll also take a look at the Oauth Lib, it seem to take care of Google access, just have to work in the Google Latutude API bit now. Just a question re the API License. If I release an app that is freeware using the API Google is it ok?

The current B4A Oauth library will not be of any use to you.
Actually OAuth 2.0 is more simpler, but requires the user to sign in and allow access through a WebBrowser or WebView.

Also, currently the Google Latitude API has a Courtesy limit of 1,000,000 queries/day and no pricing details yet so I guess that should be more than enough for you.

I suggest you have a good read of the Google Latitude API as it explains everything in detail.
