Android console error : requires compiler compliance level 5.0 or 6.0. Found '1.

自己到别的电脑上做的项目导入到自己电脑中时报错，提示Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties.
解决方案一：先下载Android1.6（API4）然后项目右键 ->android tools->Fix Project
解决方案二;检查Project->Properties->Java Compiler确认JDK compliance被设置为1.6,并且enable specific seetings.
