我尝试在android中连接speakerBluetooth（我使用UE BOOM Speaker），该设备已配对，然后我将此设备连接到我的Android手机，通过蓝牙播放音乐 . 但我失败了，这段代码可以连接，但不能在mySpeaker中播放 . 我用的是android 4.2（软糖） .

这是我的代码：

Set<BluetoothDevice> pairedDevice;
BluetoothAdapter mBtAdapter;
BluetoothSocket socket;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mBtAdapter = BluetoothAdapter.getDefaultAdapter();
    pairedDevice = mBtAdapter.getBondedDevices();
//if paired device > 0 
    if (pairedDevice.size() > 0) {
//show paired device
        for (BluetoothDevice device : pairedDevice) {
//try connect to UE BOOM Speaker
            if (device.getName().equals("UE BOOM")) {
                Method m;
                BluetoothDevice hxm = BluetoothAdapter.getDefaultAdapter()
                        .getRemoteDevice(device.getAddress());
                try {
                    m = hxm.getClass().getMethod("createRfcommSocket",
                            new Class[] { int.class });
                    socket = (BluetoothSocket) m.invoke(device, 1);

                    socket.connect();
                    Toast.makeText(this, "connect", Toast.LENGTH_SHORT)
                            .show();
                    socket.close();
                } catch (Exception ex) {
                    Toast.makeText(this, "not connect", Toast.LENGTH_SHORT)
                            .show();
                }
            }
        }
    }
}

我在舱单中的许可：

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

有什么建议吗？

问候 .
