Question

我无法使用smack传输文件，我在一边使用android模拟器，另一边使用spark。当我转移应用程序时，关闭并显示以下错误消息和文件传输请求通知，在接受文件后，传输文件时出错。下面粘贴了错误日志。

我搜索了不同的解决方案，其中一个说：

首先，你必须将smack.properties复制到你的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

我打开了网站并下载了smack的源代码但无法在任何地方找到smack.properties。第一选择关闭。

建议的第二个解决方案是更改discoverLocalIP() org.jivesoftware.smackx.filetransfer.Socks5TransferNegotiator.discoverLocalIP()中我无法找到的实现。

我如何传输文件？

@hunt创建以下函数以配置提供者资格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());

    try {

Answer 2

配置文件在

下

resources/META-INF/

你需要的是

smack-config.xml
smack.providers

您的特定错误是由于 ProviderManager 尚未配置 smack.providers 文件。这会导致传入的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。

如果您使用的是asmack，我认为已经处理过了。如果是常规Smack，则必须配置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（）方法来实现此目的。基本上复制现有的一个，但指定android资源目录而不是META-INF。已经有一个针对此的Jira任务来使目录可配置，但它尚未解决。

此外，文件传输中存在最新版本（3.2.1）中修复的错误。

asmack android，无法传输文件
