我尝试使用asmack-2010.05.07.jar共享文件，我发送成功但收到ExecutionException的0kb文件。
我的发送和接收代码是：

答案 0 :(得分：2)
正如我们所讨论的那样here - Smack在文件传输实现方面存在一些缺陷：在你的情况下，发起者提供了bytestreams和ibb方法，响应者接受两种（这是错误的）方法，下一个行程启动器提供bytestreams streamhosts，响应者选择一个，并且文件传输应该从选定的streamhost开始。但是发起人错误地启动ibb方法（原文如此！）。您可以尝试在代码中调用FileTransferNegotiator.IBB_ONLY = true;，但强烈建议您向Smack开发人员提交错误报告。
答案 1 :(得分：-1)
我认为你已经有了解决方案。
由于我严重地遇到了这个问题并找到了来自this site的解决方案，我决定在这里分享。
问题是您需要修改asmack库以增加在包org.jivesoftware.smackx.filetransfer包中的FaultTolerantNegotiator类中的createIncomingStream（）方法中的超时值。
我下载了asmack-android-6-source-0.8.1.1的源代码，并根据我提供的链接修改了源代码。它就像一个魅力！
