LocationProvider

extends Object
java.lang.Object
   ↳ android.location.LocationProvider

Class Overview

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.

public static final int OUT_OF_SERVICE

Added in API level 1

Constant Value: 0 (0x00000000)

public static final int TEMPORARILY_UNAVAILABLE

Added in API level 1

Constant Value: 1 (0x00000001)

Public Methods

public int getAccuracy ()

Added in API level 1

Returns a constant describing horizontal accuracy of this provider. If the provider returns finer grain or exact location, ACCURACY_FINE is returned, otherwise if the location is only approximate then ACCURACY_COARSE is returned.

public String getName ()

Added in API level 1

Returns the name of this provider.

public int getPowerRequirement ()

Added in API level 1

Returns the power requirement for this provider.

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

public boolean hasMonetaryCost ()

Added in API level 1

Returns true if the use of this provider may result in a monetary charge to the user, false if use is free. It is up to each provider to give accurate information.

public boolean meetsCriteria ( Criteria criteria)

Added in API level 1

Returns true if this provider meets the given criteria, false otherwise.

public boolean requiresCell ()

Added in API level 1

Returns true if the provider requires access to an appropriate cellular network (e.g., to make use of cell tower IDs), false otherwise.

public boolean requiresNetwork ()

Added in API level 1

Returns true if the provider requires access to a data network (e.g., the Internet), false otherwise.

public boolean requiresSatellite ()

Added in API level 1

Returns true if the provider requires access to a satellite-based positioning system (e.g., GPS), false otherwise.

public boolean supportsAltitude ()

Added in API level 1

Returns true if the provider is able to provide altitude information, false otherwise. A provider that reports altitude under most circumstances but may occassionally not report it should return true.

public boolean supportsBearing ()

Added in API level 1

Returns true if the provider is able to provide bearing information, false otherwise. A provider that reports bearing under most circumstances but may occassionally not report it should return true.

public boolean supportsSpeed ()

Added in API level 1

Returns true if the provider is able to provide speed information, false otherwise. A provider that reports speed under most circumstances but may occassionally not report it should return true.
