我导入一个项目，出现这个问题：
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。
网上解决方法：
step1：点击project----->propertys------>Java Build Path -----> Libraries---->Add Libraries----->JRE System Library------>选第一个workspace default jre-------->finish，

android cannot be resolved
ArrayAdapter cannot be resolved to a type。。。。重复中
