Question

我在android中使用Volley库。我在浏览器中运行相同的url并在不到一秒的时间内返回。我想知道，如何优化Volley？不清楚Cache Queue Take代表什么，以及为什么它是3.6秒。或为什么缓存队列占用和网络完成被添加为6.8秒的响应时间？如何针对不使用 ETags 的服务优化排球。还有什么是BasicNetwork.logSlowRequests

Answer 1

我刚才在这里回答：How to optimize network-queue-take in android Volley? (Volley Google IO 2013)

logSlowRequests只记录缓慢（超过3000毫秒）的请求，没有什么比这更复杂的了。 network-http-complete是下载请求并将其传递给解析器所需的时间。

Answer 2

尝试使用此Enhanced-volley

此项目基于Google自己创建的Volley Networking Toolkit for Android。工具包本身非常好且可扩展，但它缺少一些功能。该项目旨在将这些功能添加到Volley工具包中，使其成为更完整的HTTP解决方案。

您也可以自定义使用Java NIO（新IO）的库来改善回调/响应时间。使用Socket.IO

有些人还尝试使用OKHTTP排球

Answer 3

我有类似的情况。我没有像您一样注意到时间延迟，但是它显示在浏览器中，而不是我的应用程序中。本质上，清除缓存可以帮助我。

您可以通过以下方式清除缓存：

Requestqueue.getcache().clear();

如果您要为jsonrequest禁用缓存，可以通过以下方式实现：

jsonrequest.setshouldcache(false)

这解决了我的缓存问题。
