Class DeviceClass

java.lang.Object
  android.bluetooth.DeviceClass

public class DeviceClass
extends Object

The Android Bluetooth API is not finalized, and *will* change. Use at your own risk. Static helper methods and constants to decode the device class bit vector returned by the Bluetooth API. The Android Bluetooth API returns a 32-bit integer to represent the device class. This is actually a bit vector, the format defined at http://www.bluetooth.org/Technical/AssignedNumbers/baseband.htm (login required). This class provides static helper methods and constants to determine what Service Class(es), Major Class, and Minor Class are encoded in a 32-bit device class. Each of the helper methods takes the 32-bit integer device class as an argument.

Method Detail

hasServiceClass

public static boolean hasServiceClass(int deviceClass,
                                      int serviceClassType)

Returns true if the given device class supports the given Service Class. A bluetooth device can claim to support zero or more service classes.

Parameters:

deviceClass - The bluetooth device class.

serviceClassType - The service class constant to test for. For example, DeviceClass.SERVICE_CLASS_AUDIO. This must be one of the SERVICE_CLASS_xxx constants, results of this function are undefined otherwise.

Returns:

If the deviceClass claims to support the serviceClassType.

getMajorClass

public static int getMajorClass(int deviceClass)

Returns the Major Class of a bluetooth device class. Values returned from this function can be compared with the constants MAJOR_CLASS_xxx. A bluetooth device can only be associated with one major class.

getMinorClass

public static int getMinorClass(int deviceClass)

Returns the Minor Class of a bluetooth device class. Values returned from this function can be compared with the constants MINOR_CLASS_xxx_yyy, where xxx is the Major Class. A bluetooth device can only be associated with one minor class within its major class.
