Android APIs
Added in API level 1
package

android.location

Contains the framework API classes that define Android location-based and related services.

Note: The Google Location Services API, part of Google Play Services, provides a more powerful, high-level framework that automates tasks such as location provider choice and power management. Location Services also provides new features such as activity detection that aren't available in the framework API. Developers who are using the framework API, as well as developers who are just now adding location-awareness to their apps, should strongly consider using the Location Services API.
To learn more about the Location Services API, see Location APIs.

For more information about the framework API, see the Location and Maps guide.
