LocationProvider

public class LocationProvider
extends Object

java.lang.Object
   ↳ 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.

Returns
int

getName

public String getName ()

Returns the name of this provider.

Returns
String

getPowerRequirement

public int getPowerRequirement ()

Returns the power requirement for this provider.

Returns
int the power requirement for this provider, as one of the constants Criteria.POWER_REQUIREMENT_*.
