Fix this issue by adding the following to E:\Work\swietelsky\client\ink-mobile\android\app\build.gradle:
android {
  compileSdkVersion 31
  ...
}

如您所见，我已经设置了它，甚至在之前就设置了：

android {
    compileSdkVersion 31

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        applicationId "my-application-id"
        minSdkVersion 16
        targetSdkVersion 31
        multiDexEnabled true
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }
}

如您所见，已安装 SDK：

我需要建议...谢谢。

Answer 1

尝试flutter clean flutter pub get build 并再次检查。

Answer 2

对我来说，我必须更改targetSdkVersion并且它起作用了。

android {
    compileSdkVersion 31
    ...
    defaultConfig {
        applicationId "com..."
        minSdkVersion 21
        targetSdkVersion 31 // <-- Change this
        ...
    }
    ...
}
