Android locator 3qd

 

public class Location
extends Object implements Parcelable

A data class representing a geographic location. A location can consist of a latitude, longitude, timestamp, and other information such as bearing, altitude and velocity. All locations generated by the LocationManager are guaranteed to have a valid latitude, longitude, and timestamp (both UTC time and elapsed real-time since boot), all other parameters are optional.

Constant used to specify formatting of a latitude or longitude in the form "[+-]DDD:MM.MMMMM" where D indicates degrees and M indicates minutes of arc (1 minute = 1/60th of a degree).

Most Android devices allow to determine the current geo location. This can be done via a GPS (Global Positioning System) module, via cell tower triangulation and via wifi networks.

Now you can access the last known location. The fuse location provider provides a new simple API. The following is an example activity which uses it.

The Geocoder class allows to determine the geo-coordinates (longitude, laditude) for a given address and possible addresses for given geo-coordinates.

Knowing a user’s location in an Android app can be extremely useful. Users take their devices everywhere and are constantly using them on the go, and as developers we can capitalize on that by providing a more contextual experience based on their current location.

Accessing the current location of an Android device is easier than ever, but it can still be a little tricky, especially for the first time. What follows is a guide on the very basics of retrieving a user’s current location and displaying it with a marker on a map. The project files for this project are available on GitHub , but follow along and in a few minutes we’ll build a super simple location finder!

This is a somewhat complex topic in Android, but these step-by-step guidelines should explain everything you need. If you would like to learn more about the fundamentals of Android programming that lead up to this, please check out my Android Development Track on Treehouse.
