我的Andr​​oid应用程序，在Eclipse中建，突然构建失败，几十个错误。最明显的是错误表明所有的Andr​​oid进口解决不了。

My android application, built inside Eclipse, suddenly fails to build with dozens of errors. The most obvious are errors indicating that all the android imports cannot be resolved.

import android.os.Bundle;
import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.media.AudioManager;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

所有这些被标记为未解析。我试着删除并重新添加JRE系统库。我试着清洗和重建。我已经尝试了快速修复选项修复项目设置...但是这只是一个对话框，说...

All of these are flagged as unresolvable. I've tried removing and re-adding the JRE System Library. I've tried cleaning and rebuilding. I've tried the "Quick fix" option to "Fix Project Setup..." but that simply responds with a dialog box that say...

否建议已发现修复无法解决的参考android.app.Bundle。点击此处手动配置项目静音模式切换的构建路径。

我是新的Andr​​oid开发，这人有我彻底难倒。

I'm new to Android development and this one has me completely stumped.

在此先感谢您的帮助，您可以提供。

Thanks in advance for any help you can provide.

看来你的日食工作区（或者至少你的项目）以某种方式打破。

It seems that your eclipse-workspace (or at least your Project) is broken somehow.

你最近搬到你的 Android的SDK /项目？如果它不是一个Android项目了，尝试看看 preferences-＆GT;的Andr​​oid 一个有效的 Android SDK中定位。
