麻烦安装的Andr​​oid 4.2的API [英] Trouble installing Android 4.2 APIs

问题描述

我今天更新ADT通过Eclipse来21版。现在，当我打开SDK管理器我希望有能像的Andr​​oid 4.2（API 17），其中将包含SDK平台和API，文档等文件夹但是，相反，我只是得到了一个名为API 17文件夹，并在它的唯一的事情就是谷歌API的，我甚至不能安装，因为

I updated ADT through Eclipse today to version 21. Now when I open the SDK Manager I would expect there to be a folder like "Android 4.2 (API 17)", which would contain the SDK Platform and APIs, documentation, etc. However, instead I just get a folder called "API 17", and the only thing in it is "Google APIs", which I can't even install because

安装该软件包还需要安装：    - 缺少SDK平台Android的API 17

Installing this package also requires installing: - Missing SDK Platform Android, API 17

我该怎么办吗？谢谢

推荐答案

我经过一番打探想通了这一点我自己。我走进了SDK管理器的设置，清除缓存，并告诉它使用HTTPS，则刷新了上市，这一切通常出现了。

I figured this out myself after some poking around. I went into the settings for the SDK Manager, cleared the cache, and told it to use HTTPS, then refreshed the listing and it all appeared normally.
