| ↳ | android.location.LocationProvider |
An abstract superclass for location providers. A location provider provides periodic reports on the geographical location of the device.
Each provider has a set of criteria under which it may be used;
for example, some providers require GPS hardware and visibility to
a number of satellites; others require the use of the cellular
radio, or access to a specific carrier's network, or to the
internet. They may also have different battery consumption
characteristics or monetary costs to the user. The Criteria class allows providers to be selected based on
user-specified criteria.
