在android中连接蓝牙SPP的问题？

Question

public class TestConnection extends Activity {
/** Called when the activity is first created. */
public static final UUID BluetoothSerialUuid = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
private BluetoothAdapter _adapter;
BluetoothSocket socket=null;

@Override 
protected void onPause() {
    try {
        socket.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
};

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    TextView text = (TextView) findViewById(R.id.mainText);
    text.setText("This is a test");

    String deviceAddress = "05:03:e8:c0:bf:c0";
    _adapter = BluetoothAdapter.getDefaultAdapter();

    BluetoothDevice device = _adapter.getRemoteDevice(deviceAddress);

    try {
        socket = device.createRfcommSocketToServiceRecord(BluetoothSerialUuid);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    try {
        socket.connect();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

}

我正在尝试使用该站点的一些代码：

克服 android 跳过 0x00 类蓝牙设备的事实。但是，当我这样做时： _adapter.getRemoteDevice(deviceAddress);

我从来没有得到回应

我意识到失败的原因是现在在清单文件中拥有正确的权限。
