解决办法:
右键选择项目，选择Build Path——Configure Build Path...，然后在弹出框中选择：Java Build
Path——Libraries，最后将Android Dependencies和Android Private
Libraries移除(remove)掉即可。
我遇到这种问题的时候，Android Dependencies和Android Private
Libraries里面都没有我项目所需的库，所以我remove掉之后不需要重新添加jar包，但是如果你的Android
Dependencies和Android Private
Libraries里面有项目所需的库的话，需要你重新引入，否则项目会报错，jar引入：右键选择lib中的jar文件选择Add Build
Path即可。
