在 andorid.jar 中找不到 android.net.http.RequestQueue

Question

我正在开发 Android Twitter 应用程序。我下载了 TwitterClient Demo deom net。 但是在android.jar中的sDK组件中有一个class文件“android.net.http.RequestQueue”是没有的。请就此提出建议。

Answer 1

这取决于您从何处下载了该 Twitter 演示示例:

• 最初，有一个 old 2007 demo
• 一个new zip from October 2008在 this post

• 一个snippet from 2009评论如下:

android.net.http.RequestQueue is not an official part of the Android API, so it might go away or change in a future release.
You can tell by the {@hide} in the class-level JavaDoc comment in RequestQueue.java.

因此，如果最近的 API 不再有此类，您可以回退到 HttpURLConnection，如 this thread .

It seems safer to use the good ol' HttpURLConnection for HTTP calls then.
I suppose the RequestQueue was offered to save us the effort of spawning a separate thread before making the HTTP calls.

参见 this tutorial here 中说明的两种方法.
