程序包 ohos.bluetooth

类 A2dpSource

java.lang.Object

ohos.bluetooth.A2dpSource

所有已实现的接口:

ProfileBase

public final class A2dpSource
extends Object
implements ProfileBase

Manages A2DP source profiles.

The static method getProfile(ohos.app.Context) is used to obtain A2dpSource 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 A2dpSource playing status of a device.
