Android SDK API 19 KitKat离线文档
如何获取Android SDK版本19（KitKat）文档的脱机版本？
How can i get an offline version of Android SDK Version 19 (KitKat) documentation?
在API版本中。 9有一个名为Android SDK的文档的包，它将API9文档的本地副本带到< sdk> / docs ，但是没有任何等同的API19 。
In API ver. 9 there is a package named "Documentation for Android SDK" that brings a local copy of API9 docs to <sdk>/docs, but there are no any equivalent packages for API19.
但是没有任何API19的等价包
but there are no any equivalent packages for API19
是的，有：
根据屏幕截图中显示的内容，您缺少大部分的SDK软件包。我建议您进入主菜单中的工具>选项，然后单击清除缓存按钮。然后，在主菜单中进行软件包>重新加载，以尝试接收您缺少的内容。
You are missing most of the SDK packages, based on what's showing in your screenshot. I recommend that you go into Tools > Options in the main menu, and click the "Clear Cache" button. Then, do Packages > Reload in the main menu, to try to pick up what you are missing.
