类 A2dpSink

java.lang.Object

ohos.bluetooth.A2dpSink

所有已实现的接口:

ProfileBase

public final class A2dpSink
extends Object
implements ProfileBase

Manages A2DP sink profiles.

The static method getProfile(ohos.app.Context) is used to obtain A2dpSink instances.

You can use getDevicesByStates(int[]) to obtain devices in the specified state, use getDeviceState(ohos.bluetooth.BluetoothRemoteDevice) to obtain the status of a peer device, and use getPlayingState(ohos.bluetooth.BluetoothRemoteDevice) to obtain the A2dpSink playing status of a device.
