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

Question

我想使用一个颤振包“audioplayers”，但是当我运行我的代码时出现这个错误

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

当我将 myApp/android/app/build.gradle 上的 minSdkVersion 16 更改为 23 时，我又遇到了一个错误

如何解决？

Answer 1

您需要编辑位于项目目录中的build.gradle 文件，如your_project_folder\android\app\build.gradle 并找到并将此行minSdkVersion 16 编辑为minSdkVersion 23，然后使用flutter clean 命令保存文件并运行强>它。

defaultConfig 在 build.gradle 文件中应如下所示

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
    }

希望上述解决方案能奏效。

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

Answer 2

我遇到了类似的问题，在 build.gradle 中更改 SDK 版本并没有解决问题。 我只是降级到音频播放器：0.17.0，请确保删除 0 之前的 ^。它应该适合你
