蓝牙连接

private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"); 
 
private void connect(BluetoothDevice device) { 
     m_Device = device; 
     BluetoothSocket tmp = null; 
 
     // Get a BluetoothSocket for a connection with the 
     // given BluetoothDevice 
     try { 
         tmp = device.createRfcommSocketToServiceRecord(MY_UUID); 
     } catch (IOException e) { 
 
     } 
     m_Socket = tmp; 
 
     m_BluetoothAdapter.cancelDiscovery(); 
 
     try { 
         // This is a blocking call and will only return on a 
         // successful connection or an exception 
         m_Socket.connect(); 
     } catch (IOException e) { 
      try { 
       m_Socket.close(); 
      }catch (IOException e2) { 
 
         } 
      return; 
 
      } 
用上述方法连接老是出现错误，不知道他人这样用过没 后来

tmp = device.createRfcommSocketToServiceRecord(MY_UUID); 
改为

Method m = device.getClass().getMethod("createRfcommSocket", new Class[] {int.class}); 
         tmp = (BluetoothSocket) m.invoke(device, 1); 
可以了 无语中
