在BluetoothChatFragment.java添加內部handleMessage(Message msg)其中UI片段從服務接收消息的邏輯： -

case Constants.MESSAGE_READ: 
    byte[] readBuf = (byte[]) msg.obj; 
    // construct a string from the valid bytes in the buffer 
    String readMessage = new String(readBuf, 0, msg.arg1); 
    if(readMessage.equals("message required")){ 
     mConversationArrayAdapter.add(mConnectedDeviceName + ": " + readMessage); 
    } 
    break;
