Build Error

FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ':serious_python_android'.

com.android.builder.errors.EvalIssueException: [CXX1110] Platform version 16 is unsupported by this NDK. Please change minSdk to at least 21 to avoid undefined behavior. To suppress this error, add android.ndk.suppressMinSdkVersionError=21 to the project's gradle.properties or set android.experimentalProperties["android.ndk.suppressMinSdkVersionError"]=21 in the Gradle build file.

My app/build.gradle:

plugins {
    id("com.android.application")
    id("kotlin-android")
    // The Flutter Gradle Plugin must be applied after the Android and Kotlin Gradle plugins.
    id("dev.flutter.flutter-gradle-plugin")
}

android {
    namespace = "com.himanshu.test_app"
    compileSdk = flutter.compileSdkVersion
    ndkVersion = "27.0.12077973"

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_11
        targetCompatibility = JavaVersion.VERSION_11
    }

    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_11.toString()
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId = "com.himanshu.test_app"
        // You can update the following values to match your application needs.
        // For more information, see: https://flutter.dev/to/review-gradle-config.
        minSdk = flutter.minSdkVersion

        versionName = flutter.versionName
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.

[usermicrodevices]

same problem with Flutter 3.29.2

edit file $HOME/.pub-cache/git/serious-python-6c24e5b209a4a3ffca46102715a84328101f1b40/src/serious_python_android/android/build.gradle
change minSdkVersion from 16 to 21 and problem is fixed

[ndonkoHenri]

Fixed in 0.9.4 — the plugin's minSdkVersion went from 16 to 21 (#176), which is exactly the hand edit @usermicrodevices described. On 4.5.1 the Android plugin declares minSdk = 21 (serious_python_android/android/build.gradle.kts), so CXX1110 no longer fires. Since 3.0.0 we memory-map the Python extension modules straight out of the APK, so set minSdk = 23 in your own app to keep them uncompressed and page-aligned:

android {
    defaultConfig {
        minSdk = 23
    }
}
