Android requires compiler compliance level 5.0 or 6.0. Found '1.4' instead

刚导入eclipse里一个新的项目，运行时 报这个错误：

Android requires compiler compliance level 5.0 or 6.0. Found '1.4' instead. Please fix project properties 

1. 项目 右键 ->android tools ->Fix Project

2. 如果不可以，检查Project -> Properties->Java Compiler 

    确认JDK compliance被设置为1.6,并且enable specific seetings.
