uses-sdk:minSdkVersion 16 cannot be smaller than version 23 declared in library

Question

I want to use a flutter package 'audioplayers' but when I run my code I have this error

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

And when I change minSdkVersion 16 to 23 on myApp/android/app/build.gradle, I have another error

How to solve it?

Answer 1

You need to edit the build.gradle file located inside your project directory like your_project_folder\android\app\build.gradle and find and edit this line minSdkVersion 16 to minSdkVersion 23 then save the file use flutter clean command and run it.

The defaultConfig should look like this inside the build.gradle file

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
    }

Hope the above solution will work.

Or better use the old version of audioplayers. Edit in your pubspec.yaml file

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^0.1.2
  audioplayers: ^0.10.0

I had a similar problem, changing the SDK version in the build.gradle didn't solve the problem. I simply downgraded to audioplayers: 0.17.0, make sure to remove the ^ before the 0. It should work for you
