我正在尝试将我在应用程序中播放的所有音频重定向到蓝牙音箱 . 首先我配对蓝牙设备，然后我试着向audioManager'说'，我播放的所有音频都应该发送到蓝牙设备：
private final BluetoothAdapter _bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
public void pairBluetoothDevice(BluetoothDevice bluetoothDevice)
{
BluetoothSocket socket= bluetoothDevice.createInsecureRfcommSocketToServiceRecord( UUID.fromString( "0000111E-0000-1000-8000-00805F9B34FB" ) );
socket.connect();
_bluetoothAdapter.getProfileProxy( _appContext, _profileListener, BluetoothProfile.HEADSET );
}
private BluetoothProfile.ServiceListener _profileListener = new BluetoothProfile.ServiceListener()
{
public void onServiceConnected( int profile, BluetoothProfile proxy )
{
if ( profile == BluetoothProfile.HEADSET )
{
_bluetoothHeadset = (BluetoothHeadset) proxy;
_bluetoothHeadset.startVoiceRecognition(_device);
AudioManager audioManager = (AudioManager) _appContext.getSystemService(Context.AUDIO_SERVICE);
audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
audioManager.startBluetoothSco();
audioManager.setBluetoothScoOn(true);
audioManager.setSpeakerphoneOn(false);
}
}
public void onServiceDisconnected( int profile )
{
if ( profile == BluetoothProfile.HEADSET )
{
AudioManager audioManager= (AudioManager) _appContext.getSystemService(Context.AUDIO_SERVICE);
audioManager.setBluetoothScoOn(false);
audioManager.stopBluetoothSco();
audioManager.setMode(AudioManager.MODE_NORMAL);
audioManager.setSpeakerphoneOn(true);
_bluetoothHeadset.stopVoiceRecognition(_device);
_bluetoothHeadset= null;
}
}
};
当我播放音频时......
_soundPool.play( _soundPoolMap.get( index ), streamVolume, streamVolume, 1, 0, speed );
......我什么都没听到 .
谢谢你的提示:-)

我找到了以下解决方法：我打开默认的蓝牙设置，我可以配对蓝牙扬声器，而音频将自动发送到扬声器 .
