BluetoothProfile

public interface BluetoothProfile

android.bluetooth.BluetoothProfile

Public APIs for the Bluetooth Profiles.

Clients should call BluetoothAdapter#getProfileProxy, to get the Profile Proxy. Each public profile implements this interface.

Summary

Nested classes

interface BluetoothProfile.ServiceListener

An interface for notifying BluetoothProfile IPC clients when they have been connected or disconnected to the service. 

Constants

int A2DP

A2DP profile.

Coordinated Set Identification Profile set coordinator

String EXTRA_PREVIOUS_STATE

Extra for the connection state intents of the individual profiles.

String EXTRA_STATE

Extra for the connection state intents of the individual profiles.

int GATT

GATT

int GATT_SERVER

GATT_SERVER

int HAP_CLIENT

int HEADSET

Headset and Handsfree profile

int HEALTH

This constant was deprecated in API level 29. Health Device Profile (HDP) and MCAP protocol are no longer used. New apps should use Bluetooth Low Energy based solutions such as BluetoothGatt, BluetoothAdapter.listenUsingL2capChannel(), or BluetoothDevice.createL2capChannel(int)

int HEARING_AID

int HID_DEVICE

HID Device

int LE_AUDIO

LE Audio Device

int SAP

int STATE_CONNECTED

The profile is in connected state

int STATE_CONNECTING

The profile is in connecting state

int STATE_DISCONNECTED

The profile is in disconnected state

int STATE_DISCONNECTING

The profile is in disconnecting state

Public methods
