Android aSmack XMPP文件传输总是显示在进度和状态0

Question

我正在开发一个聊天应用程序，我需要在点对点聊天用户之间发送图像。现在我可以发送图像和我的文件接收器也接受请求并开始接收文件。

但打印状态始终保持打印:LOG: Progress: 0.0 &状态:In Progress

完成thread -后LOG ###文件传输未完成。状态:进行中

如果我让这个线程运行删除计数它继续保持打印-进度:0.0 &状态:In Progress

有时稍后会收到完整的图像。这需要很长时间，而且是0的一半。

我最近确实有一些asmack和smackx的经验，对它们不能太积极。

我不知道你的问题到底是从哪里来的，但我可以告诉你这是正常的。在任何进程真正开始之前，你将首先获得进度= 0的负载。如果你发送的是一个小文件，那么它就会发送得太快，以至于没有任何真正的进展。

但是，如果您成功地发送了一个更大的文件，这个函数确实工作得很好，并且会给您一个粗略的进度。

最后我们得出结论，这个功能只是有bug和限制，并实现了我们自己的文件传输xmpp消息，并处理通过我们自己的服务器发送它。像这样，你也可以发送文件给离线的人，在组(MUC)和显示一个体面的进展双方(发送& &;接收)。
