uses-sdk:minSdkVersion 16 不能小于库中声明的版本 23

Question

我想使用颤振包“audioplayers”但是当我运行我的代码时出现此错误

C:\Users\Utilisateur\AndroidStudioProjects\xylophone_flutter\android\app\src\debug\AndroidManifest.xml Error:
    uses-sdk:minSdkVersion 16 cannot be smaller than version 23 declared in library [:audioplayers] C:\Users\Utilisateur\AndroidStudioProjects\xylophone_flutter\build\audioplayers\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 23,
        or use tools:overrideLibrary="xyz.luan.audioplayers" 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 23 declared in library [:audioplayers] C:\Users\Utilisateur\AndroidStudioProjects\xylophone_flutter\build\audioplayers\intermediates\library_manifest\debug\AndroidManifest.xml as the library might be using APIs not available in 16

当我更改minSdkVersion 16为 23 on 时myApp/android/app/build.gradle，我又出现了另一个错误

如何解决？

Answer 1

您需要编辑build.gradle位于项目目录中的文件，例如your_project_folder\android\app\build.gradle找到并编辑此行minSdkVersion 16，minSdkVersion 23然后保存文件使用flutter clean命令并运行它。

在build.gradle文件中的defaultConfig应该是这样的

defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.your_package_name_here"
        minSdkVersion 23
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

希望上述解决方案会奏效。

或者更好地使用旧版本的音频播放器。在您的pubspec.yaml文件中编辑

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.2
  audioplayers: ^0.10.0
