我是新手，我正在使用flutter_html包开发移动应用程序。应用程序在
下面遇到错误"..buildwebview_flutter_androidintermediateslibrary_manifestdebugAndroidManifest.xml as the library might be using APIs not available in 16
Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project's minSdk version to at least 19,
or use tools:overrideLibrary="io.flutter.plugins.webviewflutter" to force usage (may lead to runtime failures)"
我试图将minSdk更改为16，建议此文件buildwebview_flutter_androidintermediateslibrary_manifestdebugAndroidManifest.xml。但仍然遇到一个错误。请帮忙。
请在app/build中添加minSdkVersion 21。gradle文件。
