Fix 16KB Page Size Issue in Flutter Apps for Android (Step-by-Step Guide 2025)

✅ Step 1: Update Your plugins Section

Make sure your project-level settings.gradle file includes the latest plugin versions:

plugins {

    id “dev.flutter.flutter-plugin-loader” version “1.0.0”

    id “com.android.application” version “8.11.0” apply false

    id “org.jetbrains.kotlin.android” version “2.2.20” apply false

}

✅ Step 2: Update Your Gradle Distribution

Open your gradle-wrapper.properties file and replace the existing distribution URL with the latest one:

distributionUrl=https\://services.gradle.org/distributions/gradle-8.13-all.zip

✅ Step 3: Add Core Library Desugaring Dependency

In your app/build.gradle, add the following dependency inside the dependencies block:

dependencies {

    coreLibraryDesugaring ‘com.android.tools:desugar_jdk_libs:2.1.5’

}

This ensures compatibility with the latest Android SDK features.

✅ Step 4: Update NDK Version

Inside your android block, specify the latest supported NDK version:

ndkVersion “28.2.13676358”

This version provides proper support for 16KB page sizes.

✅ Step 5: Enable Flexible Page Sizes in CMake

Finally, update your build.gradle to enable flexible page sizes:

externalNativeBuild {

    cmake {

        arguments “-DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON”

    }

}

🎯 Final Note

After completing all these steps, clean and rebuild your Flutter project:

1. flutter clean
2. flutter pub get
3. flutter build apk

Your Flutter app will now fully support 16KB page sizes and meet the Google Play Store 2025 compliance requirements. 🚀
