我正在基于this code的远程ScreenRecord实时工作。 使用此参考代码，我能够成功记录智能手机的屏幕并将.mp4文件保存在之前定义的某个文件夹中。
但是对于我的项目，我需要将此内容发送到服务器（类似于Team View for android）。
我最后一次尝试将此内容发送到服务器端是这样的：
OutputStream os = clientSocket.getOutputStream();
BufferedOutputStream bos = new BufferedOutputStream (os);
ObjectOutputStream oos = new ObjectOutputStream(bos);
oos.writeObject(encodedData);
oos.flush();
bos.flush();
os.flush();
参考=＆gt; this question
但出现错误：
java.io.NotSerializableException 在这一行＆gt;
oos.writeObject(encodedData);
然后，我想知道如何解决它或其他方式来完成这项任务。
这是完整的代码：
