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.

One of the unique features of mobile applications is location awareness. Mobile users take their devices with them everywhere, and adding location awareness to your app offers users a more contextual experience. The location APIs available in Google Play services facilitate adding location awareness to your app with automated location tracking, geofencing, and activity recognition.

The Google Play services location APIs are preferred over the Android framework location APIs ( android.location ) as a way of adding location awareness to your app. If you are currently using the Android framework location APIs, you are strongly encouraged to switch to the Google Play services location APIs as soon as possible.

This class shows you how to use the Google Play services location APIs in your app to get the current location, get periodic location updates, and look up addresses. The class includes sample apps and code snippets that you can use as a starting point for adding location awareness to your app.

Could you list all possible directories where Android apps may store data, providing description what kind of data are stored in each directory?

All apps (root or not) have a default data directory, which is /data/data/<package_name> . By default, the apps databases, settings, and all other data go here. If an app expects huge amounts of data to be stored, or for other reasons wants to "be nice to internal storage", there's a corresponding directory on the SDCard ( Android/data/<package_name> ).

Apart from that, all apps can store data anywhere on the SDCard, as there are no restrictions -- and many apps do so. They can use directory names freely (and they again do), which is what often makes it hard to decide what all that "junk" on the card is intended for, and what of it can be deleted.
