我刚刚使用 Android 和蓝牙完成了我的应用程序的开发，您可以发送消息共享文件并与蓝牙聊天。这是一个非常奇怪的应用程序，每次它显示一个错误，而其他时候它工作得很好。这是我的问题的顶部

E/BluetoothEventLoop.cpp(298): onCreateDeviceResult: D-Bus error: org.bluez.Error.AlreadyExists (Already Exists)`

第二个错误：

服务发现失败[Ljava.lang.StackTraceElement

我的代码：

    private BluetoothSocket getLaSocketConnecte(BluetoothDevice myBtServer, UUID uuidToTry)           
    { 
      BluetoothSocket myBSock; 
      try 
      { 
        if (BtAdapter.isDiscovering()) 
        { 
          BtAdapter.cancelDiscovery(); 
        } 
        myBSock = myBtServer.createRfcommSocketToServiceRecord(uuidToTry);
        myBSock.connect(); 
        return myBSock; 
      } catch (Exception e) { 
        Log.i(TAG,"IOException . Msg d'erreur :" + e.getMessage()+ e.getStackTrace()); 
      } 
      return null; 
    }

这是日志：

你能帮我找出解决方案吗？

谢谢 ：）

当时的问题与蓝牙 API 有关！
