以我为例，当我打开Eclipse并将计算机设置为睡眠模式，然后醒来工作时，我出现了错误“无效的项目描述”。我需要做的唯一一件事就是关闭我的Eclipse并再次打开它。 我看到当打开Eclipse并让计算机进入睡眠或休眠时，会犯许多其他奇怪的错误!

而不是从Android ->现有的Android代码导入工作空间，你必须使用通用->现有的项目到工作空间。这可能是一个解决方案。

这个选项解决了我的问题。

今天我意外地解决了这个问题:

以下2个步骤可能不涉及，但不确定:

从(Eclipse菜单)调用*“/Window/Android SDK Manager”并更新a)“Android SDK Tools”“Android SDK平台工具”包 从Eclipse菜单“/Help/Check for Updates”调用并更新Eclipse。重新启动Eclipse。

以下步骤是必要的:

From eclipse menu "/File/Import/Android/Existing Android Code Into Workspace" Browse and select problematic project/or problematic projectS parent directory. Check "Copy projects into workspace". Check "Add projects into working sets". Press finish. [Optional scenario]: If project(s) and their containing folders have been renamed with the fully qualified package names then simply click on project node parent (where you see project package name instead of project's old name) in Eclipse and rename project with old name. Eclipse will rename folder too.

附注:在日蚀朱诺号上测试过。

Edit: Many times have passed since this answer and new Eclipse and Android SDK arrived. They have no much more problems during importing existing projects. The only thing one has to consider before importing is to move project folders(those ones one is willing to import) outside of eclipse workspace dir and then check checkboxes ("copy projects into working sets", "add projects into wokring sets") in import wizard dialog. Also I recommend doing this with latest Android SDK because it no more imports projects with dummy names and does not rename folders as it did in some custom cases.

将项目源代码和支持库粘贴到任何其他新创建的文件夹中，并尝试从那里导入。这对我很管用。
