尝试另一个IDE，例如Idea ，检查这是否是由于Eclipse故障而不是您最近更新的SDK引起的

I my case there was something wrong with my XML usually my layout files, when you have a problem in your XML files the clean option does not work properly, check your XML files ( layout and manifest ) and after that clean your project. 以我为例，我的XML通常是layout文件有问题，当您的XML文件有问题时，clean选项无法正常工作，请检查XML文件（ layout和manifest ），然后清理您的项目。

Hope this help you 希望这对您有帮助

I did get my R.java back. 我确实恢复了R.java。 There was a jpeg for another project stuck in a drawable directory. 在可绘制目录中存在另一个项目的jpeg。 Don't know how it got there. 不知道它是怎么到达那里的。 and, still lots of unexplained errors though. 并且，仍然有许多无法解释的错误。

All my other errors were from switch statements using R.something_menu.icon for cases handling user responses. 我所有其他错误均来自使用R.something_menu.icon的switch语句，用于处理用户响应的案例。 I got a message that as of ADT 14, switch statements can no longer be used. 我收到一条消息，从ADT 14开始，不再可以使用switch语句。 I had to migrate to if...else It works. 我必须迁移到...，否则它可以工作。 Don't know why. 不知道为什么。 But, it solved the problem & saved my code. 但是，它解决了问题并保存了我的代码。
