I have a created an Android app which is like google maps, but inside door. The app determines the coördinates of the user location in building, and shows this in a map. The app uses Wifi access points to determine the coördinates.
Now what i need is, when the Android app gathers coördinates from wifi access points, the app must send these coördinates to my server, and the server must then determine the location of the coördinates, and send the data back to the Android phone (basicaly an Android client-server program). Which then the app can show the location in the map.
The program is written in Java, so i use Java for this app.
Btw (i use Ubuntu Server 11.04)
