关于安卓开发调试中提示is missing required library:'android-support-v4.jar'，v7.jar,class.jar的解决方案

              在Private-libraries中找到对应的jar包，然后配置一下。如果已经配置，将配置好

            的删除掉就可以了。另外的方法如下：

           I think you have to configure Buildpath of your project. Do this as suggested      

           below: 

            RightClick on your Project -> Build Path -> Configure B              uildpath

             Then the window be will be shown with Libraries as one of the tab. Select 

              that tab.

           

             Then click Add External Jars in the right side buttons list. Add the 

              required Jars and select OK. Once clean and build your project.
