我已经更新了采用Android的SDK管理器我的包，并点击帮助>检查更新和更新安装的插件。我被提示重新启动Eclipse，现在重启后，

我获得以下错误code

解决方案

您一定有正确的依赖？其中Eclipse版本，你已经安装了？其中JRE / JDK是用来运行Eclipse呢？

错误版本号意味着有预定的目标Java版本，并使用一个不匹配（见的这里）。

I have updated my packages using Android SDK Manager and clicked on Help > Check for updates and updated installed plug-ins. I was prompted to restart eclipse, and now after restarting,

I get following Error code

You sure to have the correct dependencies? Which eclipse version do you have installed? Which JRE/JDK is used to run eclipse with?

Bad version number means that there is a mismatch between the intended target java version and the one you use (see here).
