项目需要用到ViewPager，毫不犹豫的引入了官方提供的android-support-v4.jar

开发过程平淡无奇，签名打包时出现了两个问题

1.使用eclipse导出签名apk出现错误

[java] view plain copy

原因：

[java] view plain copy
  1. AndroidCompatibilitylibraryreferencingclassesthatonlyexistinrecentversionsoftheAndroidAPI
解决方法：在项目的proguard.cfg文件中添加 

                  [java] view plain copy                         
         
  1.  -dontwarn**HoneycombMR2
    2.      
  2.  -dontwarn**CompatICS
    3.      
  3.  -dontwarn**Honeycomb
    4.      
  4.  -dontwarn**CompatIcs*
    5.      
  5.  -dontwarn**CompatFroyo
    6.      
  6.  -dontwarn**CompatGingerbread
    7.     
      具体要dontwarn哪些条目，可以根据报错来进行相应的修改
    
   

 
   
2.使用命令行脚本生成的apk无法运行，当运行到android-support-v4.jar相关的类时，出现ClassNotFoundException
 解决方法：运行dx命令时，将android-support-v4.jar加入class.dex
 
   
                  [java] view plain copy                         
         
  1.  %DX%--dex--output=%OUT_FOLDER%\classes.dex%OUT_CLASS_FOLDER%%THIRD_JAR%
