问题描述
当我去Android SDK中经理从日食，并试图安装新的软件包它不允许我安装的话。
When I go to Android SDK Manager from eclipse and trying to Install new packages it doesn't allow me to install any of them.
大多数这些新的软件包取决于安装的Android API 17 SDK平台。但Android的API 17 SDK平台并不在对Android SDK管理器列表加载我安装。
Most of these new packages depends on installing "Android API 17 SDK platform". But the "Android API 17 SDK platform" doesn't load in the list on the Android SDK Manager for me to install.
以下是它显示以避免在安装该消息的屏幕截图。
Following is a screenshot of the message it displaying to avoid installation.
将不胜感激，如果有人能指导我通过这个。谢谢你。
Would be grateful if someone can guide me through this. Thanks.
推荐答案
清除工具下的高速缓存 - >选项或完全禁用它。我的包无法显示，因为缓存以前也有问题。
Clear the Cache under Tools ---> Options or disable it entirely. I've had problems before with packages not showing because of Cache.
之后，确保正确的站点被启用，并在包过滤器是正确的。然后重新装入列表或重新启动SDK管理器。
After that Make sure the correct Sites are enabled and the Filters under Packages are correct. Then Reload the List or Restart SDK Manager.
您还在使用平台工具V12，目前一个是V16。大概是因为缓存你不能更新的工具和旧工具，有些事情不会显示在所有。如果没有这个工程从Android开发者主页上安装与V16平台工具的当前V21 SDK。
Your still using Platform tools v12, the current one is v16. Probably because of Cache you cant update the tools and in the old tools some things wont show at all. If none of this works install the current v21 SDK with v16 Platform tools from the Android developer homepage.

自动更新缓存。然而，在工具20.0.0和20.0.1，
这刷新坏了，在一定条件下管理器将不
除非显示执行重载可用的新工具。
清除SDK管理器缓存或手动强制重装部队
经理以获得最新的清单。
"Explanation: The SDK Manager in Tools 20.0.0 now has a cache mechanism -- it keeps a local copy of small manifest XML files to perform a faster start when opened. There's also a mechanism to automatically update the cache. However in Tools 20.0.0 and 20.0.1, that refresh is broken and in some conditions the manager will not show new tools that are available unless a reload is performed. Clearing the SDK Manager cache or manually forcing a reload forces the manager to get the latest manifest."
