The Location API is designed to work with many different positioning methods. Generic interfaces lets application developers implement systems that can retrieve ___location data from multiple sources, based on their availability on the device. It has advantages over a single means of tracking, including fail-over, indoor/outdoor transparency, and a choice between the speed and accuracy trade-offs between [[Global Positioning System|GPS]], cellular, or other positioning methods. The API supports:<ref>[http://www.ddj.com/java/184406388 Dr. Dobb's 2006 - The Java Location API]</ref>
*Current ___location - current [[latitude]], [[longitude]], [[altitude]], [[direction]], and [[speed]] of the phone, and methods to convert it to [[Geographic_coordinate#Degrees:_a_measurement_of_angle|text]].
*Address data - textual details such as the current ___location's postal address, phone number, country, and the building and its URL.<ref>[http://www.ddj.com/showArticle.jhtml?documentID=ddj0601i&pgno=8 Dr. Dobb's 2006 - The Java Location API - Address Information]</ref>▼
*Landmark proximity - a store of landmarks can be stored on the phone's memory, and the current ___location can be added as a landmark.
▲*Address data - the nearest landmark's textual details, such as
*Location listeners - for dynamic ___location-based applications that will be triggered by when the current ___location changes.
