Any help or suggestions would be immensely appreciated. 任何帮助或建议，将不胜感激。 Thank you for your time :) 感谢您的时间 ：）

Edit 1: My problem is fixed now. 编辑1：我的问题现在已解决。 I ended up trying another SDK and the problem persisted. 我最终尝试了另一个SDK，问题仍然存在。 I ended up becoming impatient and created a new project and reimported my source. 我最终变得不耐烦，创建了一个新项目，然后重新导入了我的资源。 This leads me to believe that my problem may have been partially due to corrupt .cproject and/or .project files. 这使我相信我的问题可能部分是由损坏的.cproject和/或.project文件引起的。

This is probably a super subjective thing since the error is so generic, but a good thing to do is to check your .cproject. 这可能是超级主观的，因为错误是如此普遍，但是要做的一件好事是检查您的.cproject。

I have my .cproject checked into version control and I noticed it contained these additions: 我将.cproject签入版本控制，我注意到它包含以下新增内容：

<cconfiguration id="0.1230402123.1377291156"> <storageModule buildSystemId="org.eclipse.cdt.managedbuilder.core.configurationDataProvider" id="0.1230402123.1377291156" moduleId="org.eclipse.cdt.core.settings" name="Debug"> <externalSettings/> <extensions> <extension id="org.eclipse.cdt.core.VCErrorParser" point="org.eclipse.cdt.core.ErrorParser"/> <extension id="org.eclipse.cdt.core.GmakeErrorParser" point="org.eclipse.cdt.core.ErrorParser"/> <extension id="org.eclipse.cdt.core.CWDLocator" point="org.eclipse.cdt.core.ErrorParser"/> <extension id="org.eclipse.cdt.core.GCCErrorParser" point="org.eclipse.cdt.core.ErrorParser"/> <extension id="org.eclipse.cdt.core.GASErrorParser" point="org.eclipse.cdt.core.ErrorParser"/> <extension id="org.eclipse.cdt.core.GLDErrorParser" point="org.eclipse.cdt.core.ErrorParser"/> </extensions> </storageModule> <storageModule moduleId="org.eclipse.cdt.core.externalSettings"/> </cconfiguration>

Once I closed Eclipse, removed those, and restarted the error went away. 一旦我关闭Eclipse，将其删除，然后重新启动，错误就消失了。 Recreating a project would do the same, but I didn't want to redo my painstakingly setup project. 重新创建项目也可以这样做，但是我不想重做我辛苦设置的项目。 Hope this helps. 希望这可以帮助。

This is because a Android SDK outside of eclipse is corrupt. 这是因为eclipse之外的Android SDK已损坏。 You should find it, delete it and download a new one at http://developer.android.com/sdk/index.html Then you run android SDK manager afterward to make sure there are no updates. 您应该找到它，将其删除，然后在http://developer.android.com/sdk/index.html下载一个新的。然后运行android SDK Manager，以确保没有更新。

Check this question out. 检查这个问题。 It might help errors when eclipse loading 蚀加载时可能会帮助错误
