通过XMPP在Android中进行文件传输？

我只是试图通过xmpp传输文件，我正在使用asmack lib。我在下面遇到异常。

现在此行不会引起任何问题。首先，您必须将smack.properties复制到您的android模拟器。 您可以在原始的SMACK API网站上获得ѭ3。 http://www.igniterealtime.org/downloads/source.jsp 将smack.properties推送到\“ / data / \”文件夹中。 修改的方法（在中）。 查找以下行。Enumeration providerEnum = classLoader.getResources( \"/META-INF/smack.providers\");Enumeration providerEnum = classLoader.getResources( \"/data/smack.providers\");马口
