Android Smack 4.1.1 文件传输，错误无法建立套接字

Question

我正在尝试使用 smack 库 4.1.1 通过我的 android 应用程序发送文件，尽管我在这样做时遇到了一些错误。问题是我不知道为什么它只是将文件发送到设备但之后它不允许我发送给其他人而其他人也不能发送给其他人，例如我第一次打开监听器对于一个设备，该设备可以并且仍然可以仅将文件发送到一个设备(它发送的第一个设备)但是接收的设备不能，文件似乎到达但数据为 0 或者可能没有到达并且只是何时到达某事导致错误我不确定但过了一会儿我不知道连接或某些东西是否中断我可以用任何其他设备发送文件但不能用另一个设备发送文件，只有一个。而其他人得到这个错误:

我还使用 spark 对其进行了测试，我可以从 spark 完美地接收文件，即使当我将文件发送到 spark 时它也显示 spark 错误。

这真的很奇怪，我真的不知道我做错了什么。看看我的代码

发送文件:

public static void sendFile(String Username, String filePathAndName, AbstractXMPPConnection connection){
        Log.e("FILENAMEing file", "to " + Environment.getExternalStorageDirectory() + File.separator + Example.DB_FOLDER + File.separator + "myText.jpg");
        Log.e("FILENAMEing file", "to " + Username);

        FileTransferManager manager = FileTransferManager.getInstanceFor(connection);
        OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer(Username + Example.DOMAIN + "/" + Example.APP_NAME);
        try {
            transfer.sendFile(new File(filePathAndName), "This is a Test!");
        } catch (SmackException e) {
            e.printStackTrace();
        }

    }

接收文件:

public static void setFileTransferListener(AbstractXMPPConnection 连接){

    FileTransferManager manager = FileTransferManager.getInstanceFor(connection);
    // Create the listener
    manager.addFileTransferListener(new FileTransferListener() {
        @Override
        public void fileTransferRequest(FileTransferRequest request) {
            IncomingFileTransfer transfer = request.accept();
            try {
                File file = new File(Environment.getExternalStorageDirectory()  + File.separator + Example.DB_FOLDER + File.separator + "myFile22.jpg");
                transfer.recieveFile(file);
            } catch (SmackException | IOException e) {
                e.printStackTrace();
            }
        }
    });
}

我很乐意阅读任何答案或提示。我坚持了 2 天 D:我真的需要帮助:/。

端口是转发的，就像我说的那样，它适用于一个设备或我认为首先打开监听器的第一个设备。

Answer 1

我希望这对任何人都有帮助，即使我们需要更改 openfire 服务器中的某些属性，api 也能正常工作:

1.  xmpp.proxy.enabled – true 
2.  xmpp.proxy.port – 7777 (7777 is the default but could be another)
3.  xmpp.proxy.externalip – (host or ip)

当时它运行良好，但需要进行更多测试，我错了，请有人提供任何其他信息来解决此问题。
