android studio 错误

 Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version 15 declared in library [com.github.armcha:LuseenBottomNavigation:1.8.2] C:\Users\Administrator\.android\build-cache\9451a382f6bde2859291b53196320c14cb4512a0\output\AndroidManifest.xml

Suggestion: use tools:overrideLibrary="com.luseen.luseenbottomnavigation" to force usage

网上搜的的答案无非两种，一种是改依赖裤，可是我是gradle 下载下来的，不知道怎么改，再个就是上面的 可是敲了半天没这标签，于是不知到怎么搞了，想minsdk,我就想到另外的修改方式，就尝试了一下，成功了
