asmack android，无法传输文件

Question

我无法使用 smack 传输文件，我在一侧使用 android 模拟器，在另一侧使用 Spark。当我进行传输时，应用程序强制关闭，并显示以下错误消息和文件传输请求的通知，在接受文件后，传输文件时出错。错误日志粘贴在下面。

我搜索了不同的解决方案，其中之一说：

首先，您必须将 smack.properties 复制到您的 Android 模拟器。 您可以在原始 SMACK API 站点获取 smack.properties。

http://www.igniterealtime.org/downloads/source.jsp< /p>

我打开了该网站并下载了smack的源代码，但无法在任何地方找到smack.properties。 第一选择已关闭。

提出的第二个解决方案是更改我无法找到的 org.jivesoftware.smackx.filetransfer.Socks5TransferNegotiator.discoverLocalIP() 中的 discoverLocalIP() 的实现。

我怎样才能传输文件？

@hunt 创建以下函数来配置提供程序 Mager 并在发送文件之前调用它。

public void configureProviderManager() {
    ProviderManager pm = ProviderManager.getInstance();

    // The order is the same as in the smack.providers file

    //  Private Data Storage
    pm.addIQProvider("query","jabber:iq:private", new PrivateDataManager.PrivateDataIQProvider());

Answer 2

配置文件位于

resources/META-INF/

您需要的文件下，

smack-config.xml
smack.providers

您的具体错误是由于尚未使用 smack.providers 文件配置 ProviderManager 引起的。这会导致传入数据包被读入默认的 PacketExtension，而不是为特定节类型配置的数据包。

如果您使用 asmack，我认为这已经可以处理了。如果是常规 Smack，您将必须配置 ProviderManager 以从正确的位置读取文件。

我认为您可以通过扩展 ProviderManager 并覆盖 initialize() 方法来做到这一点。基本上复制现有的，但指定 android 资源目录而不是 META-INF 目录。已经有一个 Jira 任务针对此问题来使目录可配置，但尚未解决。

此外，文件传输中存在一个错误，已在最新版本（3.2.1）中修复。
