How to switch audio output between bluetooth and speaker? (Both Android and IOS)

Hello,

Changing the playback device in Android can only be done in call mode. In iOS, users can only select the playback device through the control center.

On the Android platform, you can refer to the following code to set the call mode and change the playback device.

Step 1. Instantiate MainActivity.

public class MainActivity : MauiAppCompatActivity

{

    public static MainActivity Instance { get; private set; }

    protected override void OnCreate(Bundle? savedInstanceState)

    {

        base.OnCreate(savedInstanceState);

        Instance = this;

    }

}

Step 2. Create the AudioHelper class in Android folder.

public static class AudioHelper

{

    public static void PlayWithSpeaker()

    {

        AudioManager audioManager = (AudioManager)MainActivity.Instance.GetSystemService(Context.AudioService);

        audioManager.Mode = Mode.InCommunication;

        audioManager.BluetoothScoOn = false;

        audioManager.SpeakerphoneOn = true;

    }

 

    public static void PlayWithBluetooth()

    {

        AudioManager audioManager = (AudioManager)MainActivity.Instance.GetSystemService(Context.AudioService);

        audioManager.Mode = Mode.InCommunication;

        audioManager.BluetoothScoOn = true;

        audioManager.SpeakerphoneOn = false;

        audioManager.StartBluetoothSco();

 

    }

}

Step 3. Invoke the method on maui.

#if ANDROID

            AudioHelper.PlayWithSpeaker();

#endif
