Question

我正在尝试使用smack库4.1.1在我的Android应用程序上发送文件，尽管我有一些错误要这样做。问题是，我不知道为什么它只是将文件发送到设备但在此之后它不允许我发送给其他人而其他人也无法发送给其他人，例如我第一次用一个设备打开一个监听器，该设备可以并且仍然可以将文件发送到一个设备（它发送的第一个）但是接收的设备不能，文件似乎到达但是有0个数据或者它没有＆＃39; t到达并且刚到达的时候出现错误我不确定但是过了一段时间我不知道连接或是什么东西坏了我可以用任何其他设备发送文件而不用另一个设备发送文件，只有一个。其他人得到这个错误：

我也用火花测试它，我可以完美地从火花接收文件，即使我发送文件火花它也显示火花错误。

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();
        }

    }

收到文件：

public static void setFileTransferListener（AbstractXMPPConnection connection）{

    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：/。

这个端口是转发的，就像我说它适用于一个设备或第一个设备，我认为首先打开一个监听器。

Answer 1

我希望这对任何人都有帮助，即使我们需要在openfire服务器中更改某些属性，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)

当它运作良好时，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这个问题。
