简述:

今天用到flutter的一个第三方webview框架，但是无法正常编译，编译了两次都失败了，

报错信息:

uses sdk:minSdkVersion 16 cannot be smaller than version 17 declared in library [:flutter_inappwebview] E:\workspace\Flutter\flutter_app\build\flutter_inappwebview\intermediates\library_manifest\debug\AndroidManifest.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 17,
		or use tools:overrideLibrary="com.pichillilorenzo.flutter_inappwebview" to force usage (may lead to runtime failures)

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 17 declared in library [:flutter_inappwebview] E:\workspace\Flutter\flutter_app\build\flutter_inappwebview\intermediates\library_manifest\debug\AndroidManifest.xml as the library might be using APIs not available in 16

BUILD FAILED in 8m 55s
Exception: Gradle task assembleDebug failed with exit code 1

问题原因:

minSdkVersion 版本过低导致的，因第三方库中使用到minSdkVersion 高版本才有的特性，导致低版本的无法识别和编译
