应用程序显示错误，无法修复

Question

我正在做一个Android应用程序。它工作正常，我可以在星期二运行它。当我昨天打开它给出以下错误。

Description Resource Path Location Type 
/SplashScreen/gen already exists but is not a source folder. Convert to a source folder or rename it. SplashScreen  line 1 Android ADT Problem 

The type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files ProductXmlManager.java /SplashScreen/src/com/ust/mobile/android/jnj/mxr/xmlmanager line 1 Java Problem 

The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project SplashScreen  Unknown Java Problem 

Answer 1

看起来像你的开发环境的错误，而不是应用程序。如果您更改了某些内容并检查了构建路径，请检查设置。
