Jingle-Android 文件传输

Question

我正在尝试在我的应用程序中通过 jingle 实现文件传输。有人可以帮

我解决这个错误吗？我不明白为什么当服务器可以

使用 Spark 处理文件传输时它说服务不可用，所以我想我可能忘记了有关

应该添加的提供程序或扩展的信息。

我已经有了这个：

    pm.addIQProvider("jingle", "http://jabber.org/protocol/jingle",
            new org.jivesoftware.smackx.provider.JingleProvider());

    pm.addExtensionProvider("description", "http://jabber.org/protocol/jingle/description/audio",
            new org.jivesoftware.smackx.provider.JingleContentDescriptionProvider.Audio());

    pm.addExtensionProvider("description", "http://jabber.org/protocol/jingle/description/audio",
            new org.jivesoftware.smackx.provider.JingleContentDescriptionProvider.Audio());

    pm.addExtensionProvider("transport", "http://jabber.org/protocol/jingle/transport/ice",
            new org.jivesoftware.smackx.provider.JingleTransportProvider.Ice());

    pm.addExtensionProvider("transport", "http://jabber.org/protocol/jingle/transport/raw-udp",
            new org.jivesoftware.smackx.provider.JingleTransportProvider.RawUdp());

    pm.addExtensionProvider("busy", "http://jabber.org/protocol/jingle/info/audio",
            new org.jivesoftware.smackx.provider.JingleContentInfoProvider.Audio.Busy());

    pm.addExtensionProvider("hold", "http://jabber.org/protocol/jingle/info/audio",
            new org.jivesoftware.smackx.provider.JingleContentInfoProvider.Audio.Hold());

    pm.addExtensionProvider("mute", "http://jabber.org/protocol/jingle/info/audio",
            new org.jivesoftware.smackx.provider.JingleContentInfoProvider.Audio.Mute());

    pm.addExtensionProvider("queued", "http://jabber.org/protocol/jingle/info/audio",
            new org.jivesoftware.smackx.provider.JingleContentInfoProvider.Audio.Queued());

    pm.addExtensionProvider("ringing", "http://jabber.org/protocol/jingle/info/audio",
            new org.jivesoftware.smackx.provider.JingleContentInfoProvider.Audio.Ringing());

对于 Smack Jingle 文件传输，“服务不可用”意味着另一方无法接受请求。
