The LocationKit API provides a unified library across platforms and devices that can be used to request location information.
LocationKit supports three different methods to obtain location information:
Standalone GPS (SGPS) uses the GPS chipset in devices that can obtain GPS information without network assistance
Cell ID uses the location of the cell the device is currently talking to provide a quick approximate location that can be used to obtain local information
Wi Fi ID uses the visible Wi-Fi networks that the device can see (assuming the Wi-Fi radio is turned ON) to obtain an approximate location that is much more accurate than the Cell ID location when a match is found in the database.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
