曾在Eclipse中出现以下错误安装后的And​​r​​oid 5.0（SDK 21）

Had the following error in Eclipse after installing Android 5.0 (SDK 21)

"Loading data for Android 5.0" has encountered a problem. 

Parsing Data for android-21 failed  
unsupported major.minor version 51.0

我仍然面临MAC同样的问题。现在作为一些答案尝试的Java 1.8，我发现它的最新版本。老不可用。 我已经有更新的Java，但我不知道它什么错了。

I am still facing the same problem on mac. and now as in the few answers try java 1.8 where i found the latest version of it. old is not available. I already have updated java but i don't know whats wrong with it.

请帮我尽快..

推荐答案

您需要安装Java V7。 Android不支持Java V8呢。你可以从最新的Java V7 这里。

You will need to install Java v7. Android doesn't support Java v8 yet. You can get the latest Java v7 from here.

当你更新你的Andr​​oid SDK，您必须同时在同一时间更新您的Andr​​oid开发工具（ADT）。如果你不这样做，你会得到各种各样的错误。

When you update your Android SDK, you must also update your Android Development Tools (ADT) at the same time. If you don't, you'll get all sorts of errors.

更新：截至2014年12月15日的，Mac®OS操作系统X®版本10.1​​0尚不支持Android SDK中。请参见这里获取更多信息。

UPDATE: As of December 15 2014, Mac® OS X® version 10.10 is not yet supported by Android SDK. See here for more info.
