我下载了facebook SDK for android并将其添加到我的项目中。 Eclipse告诉我，我使用了3个android-support-v4.jar文件，如错误所示：
[2015-01-09 11:53:00 - Citizengage] Found 3 versions of android-support-v4.jar in the dependency list,
[2015-01-09 11:53:00 - Citizengage] but not all the versions are identical (check is based on SHA-1 only at this time).
[2015-01-09 11:53:00 - Citizengage] All versions of the libraries must be the same at this time.

那么我怎样才能只使用一个与3个库不冲突的android-support-v4.jar？
