我正在尝试创建2个版本的Android应用程序(免费/付费).我有一个Android库,其中包含两者共有的文件.我创建了一个新的Android项目,并尝试使用该库,但得到以下错误:

Found 2 versions of android-support-v4.jar in the dependency list,
but not all the versions are identical (check is based on SHA-1 only at this time).
All versions of the libraries must be the same at this time.
Versions found are:
Path: /Users/Zaheer/Developer/App Free/libs/android-support-v4.jar
    Length: 349252
    SHA-1: 612846c9857077a039b533718f72db3bc041d389
Path: /Users/Zaheer/Developer/App Library/libs/android-support-v4.jar
    Length: 337562
    SHA-1: 27c24d26e4c5d57976e6926367985548678e913c

关于如何解决这个问题的任何想法？我一直在玩构建路径,但没有成功.
