大佬求救，制作原生sdk，依赖了一个第三方的arr，然后制作自定义基座失败了

这几天遇到了需要接入原生sdk的需求，完全不懂。
对方提供了个arr文件，只能跟着文档去进行集成
在android studio上面调试是跑得了，但是想打包成uniapp插件的时候却失败了
无奈，安卓一点不懂，请各位巨佬指教一下

以下是制作自定义基座的错误信息

[PackagePath]/app/AndroidManifest.xml Error:  
uses-sdk:minSdkVersion 19 cannot be smaller than version 21 declared in library [tosbsdk-release_1.0.1.aar] /home/[Name]/.gradle/caches/transforms-3/4a26b2c6259806c2f89b0db3a6eddfe5/transformed/jetified-tosbsdk-release_1.0.1/AndroidManifest.xml as the library might be using APIs not available in 19  
Suggestion: use a compatible library with a minSdk of at most 19,  
or increase this project's minSdk version to at least 21,  
or use tools:overrideLibrary=\"com.khy.tosb.sdk\" to force usage (may lead to runtime failures)
