Provides classes that manage Bluetooth functionality, such as scanning for devices, connecting with devices, and managing data transfer between devices. The Bluetooth API supports both "Classic Bluetooth" and Bluetooth Low Energy.
For more information about Classic Bluetooth, see the Bluetooth guide. For more information about Bluetooth Low Energy, see the Bluetooth Low Energy (BLE) guide.
The Bluetooth APIs let applications:
To perform Bluetooth communication using these APIs, an application must
declare the BLUETOOTH
permission. Some
additional functionality, such as requesting device discovery,
also requires the BLUETOOTH_ADMIN
permission.
Note: Not all Android-powered devices provide Bluetooth functionality.
BluetoothAdapter.LeScanCallback | Callback interface used to deliver LE scan results. |
BluetoothProfile | Public APIs for the Bluetooth Profiles. |
BluetoothProfile.ServiceListener | An interface for notifying BluetoothProfile IPC clients when they have been connected or disconnected to the service. |
BluetoothA2dp | This class provides the public APIs to control the Bluetooth A2DP profile. |
BluetoothAdapter | Represents the local device Bluetooth adapter. |
BluetoothAssignedNumbers | Bluetooth Assigned Numbers. |
BluetoothClass | Represents a Bluetooth class, which describes general characteristics and capabilities of a device. |
BluetoothClass.Device | Defines all device class constants. |
BluetoothClass.Device.Major | Defines all major device class constants. |
BluetoothClass.Service | Defines all service class constants. |
BluetoothDevice | Represents a remote Bluetooth device. |
BluetoothGatt | Public API for the Bluetooth GATT Profile. |
BluetoothGattCallback |
This abstract class is used to implement BluetoothGatt callbacks.
|
BluetoothGattCharacteristic |
Represents a Bluetooth GATT Characteristic
A GATT characteristic is a basic data element used to construct a GATT service,
|
BluetoothGattDescriptor |
Represents a Bluetooth GATT Descriptor
GATT Descriptors contain additional information and attributes of a GATT
characteristic, |
BluetoothGattServer | Public API for the Bluetooth GATT Profile server role. |
BluetoothGattServerCallback |
This abstract class is used to implement BluetoothGattServer callbacks.
|
BluetoothGattService |
Represents a Bluetooth GATT Service
Gatt Service contains a collection of |
BluetoothHeadset | Public API for controlling the Bluetooth Headset Service. |
BluetoothHealth |
This class is deprecated.
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)
|
BluetoothHealthAppConfiguration |
This class is deprecated.
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)

|
BluetoothHearingAid | This class provides the public APIs to control the Hearing Aid profile. |
BluetoothHidDevice | Provides the public APIs to control the Bluetooth HID Device profile. |
BluetoothHidDevice.Callback | The template class that applications use to call callback functions on events from the HID host. |
BluetoothHidDeviceAppQosSettings | Represents the Quality of Service (QoS) settings for a Bluetooth HID Device application. |
BluetoothHidDeviceAppSdpSettings | Represents the Service Discovery Protocol (SDP) settings for a Bluetooth HID Device application. |
BluetoothLeAudio | This class provides the public APIs to control the LeAudio profile. |
BluetoothManager |
High level manager used to obtain an instance of an BluetoothAdapter
and to conduct overall Bluetooth Management.
|
BluetoothServerSocket | A listening Bluetooth socket. |
BluetoothSocket | A connected or connecting Bluetooth socket. |
BluetoothStatusCodes | A class with constants representing possible return values for Bluetooth APIs. |
