Today, because of the needs of the work, the previous compilation of a GPS test program has been revised again. This program is a bit of a history, I wrote 11 years, when I learned how to develop Android, is an experimental work. Now the work needs to be put back out to fix. At the same time I found that the Android GPS

First of all, the acquisition of GPS data positioning methods are: GPS satellite positioning, WiFi location, base station positioning, AGPS positioning. The application of GPs is regarded as the core in the software of lbs industry. Several positioning ways to explain

Now many well-known websites provide open platforms for developers, such as Baidu and Renren! Here is an example of Baidu map provided by Baidu.Program, Has the following features:
(1) Locating the current location (GPS is not used, and positioning is fast and accurate ),
(2) find nearby locations (scenic spots, KFC, etc ),
(3) Get the route to this location
(4) share the route to everyone
