Android APIs
Added in API level 1
package

android.location

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

This API is not the recommended method for accessing Android location.
The Google Location Services API, part of Google Play services, is the preferred way to add location-awareness to your app. It offers a simpler API, higher accuracy, low-power geofencing, and more. If you are currently using the android.location API, you are strongly encouraged to switch to the Google Location Services API as soon as possible.

To learn more about the Google Location Services API, see the Location API overview.
