Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version 16 declared in library

错误内容：

 Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version 16 declared in library

产生原因：
某个依赖包的manifests中的minSdkVersion版本比项目的minSdkVersion要高
解决方法：
1.更改项目的uses-sdk:minSdkVersion
2.更改依赖包的uses-sdk:minSdkVersion
3.在项目的manifests标签下添加

 xmlns:tools="http://schemas.android.com/tools"
 tools:overrideLibrary="依赖包的包名"

多个依赖包存在这样的异常
