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。昨天我打开它时发出以下错误。

  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

似乎是您的开发环境的错误，而不是应用程序。如果您更改了某些内容并检查构建路径，请检查设置。
