Before you start
Android builds can be created on Windows, macOS or Linux. You need Flutter, Android Studio or Android command-line tools, and a correctly configured Android SDK.
Required to run, test and build the generated Flutter app.
Installed through Android Studio or standalone Android command-line tools.
Use Visual Studio Code with Flutter extensions, or Android Studio if you prefer native Android tools.
Extract the generated Flutter source code before running commands.
Step-by-step Android build flow
Use this workflow after extracting the ZIP file containing your Wrapply Flutter source code.
Open the project in Visual Studio Code
Extract the source code ZIP and open the project root folder in VS Code. Install the Flutter and Dart extensions if they are not installed yet.
Install project dependencies
Run flutter pub get from the project root to download all required Flutter packages.
Check your Flutter setup
Run flutter doctor and fix Android SDK, licenses or device warnings before building.
Update the Android package name
Before publishing, use a unique package name such as com.yourcompany.yourapp. This identifies your app on Android and Google Play.
Test the app
Connect an Android device or start an emulator, then run flutter run to test the generated app.
Build the APK
Generate a release APK when you want an installable Android file for testing, internal distribution or direct sharing.
Build the AAB
Generate a release Android App Bundle when you want to upload the app to Google Play Console.
flutter pub get
flutter doctor
flutter run
flutter build apk --release
flutter build appbundle --release
Where to change Android app settings
Most Android-specific settings are inside the android folder. The exact files may vary depending on your Flutter version and Gradle setup.
Usually configured in Android Gradle files and Android manifest references. It should be unique before publishing.
Usually configured in Android resources or manifest metadata, depending on the project structure.
Android launcher icons are stored inside the Android resources folders, usually under
android/app/src/main/res.
Add or review Android permissions inside
android/app/src/main/AndroidManifest.xml.
Controlled by Flutter build version values and Android Gradle configuration.
Production builds require a signing key. Wrapply can generate signed builds, but custom publishing workflows may require your own key.
APK vs AAB: which one should you use?
APK and AAB files serve different purposes. Wrapply can generate both depending on your package and publishing goal.
APK files can be installed directly on Android devices and are useful for demos, validation and quick sharing.
AAB files are used by Google Play Console for production distribution and optimized app delivery.
Required when distributing an APK outside your development environment.
Required when preparing a production-ready upload for Google Play.
Common Android build issues
Most Android build problems are related to missing SDK setup, Gradle configuration, package name conflicts or signing configuration.
Install Android Studio or configure the Android SDK path correctly, then run
flutter doctor.
Run
flutter doctor --android-licenses and accept the required licenses.
Choose a unique package name before uploading to Google Play Console.
Check your keystore, key alias, passwords and Gradle signing configuration.
flutter doctor
flutter doctor --android-licenses
flutter clean
flutter pub get
flutter build appbundle --release
Managed Android build and publishing
If you do not want to manage Flutter commands, package name configuration, signing and Play Console upload manually, Wrapply can generate signed APK and AAB files and assist with managed Google Play publishing.
FAQ
Can I build Android apps on Windows?
Yes. Android Flutter builds can be created on Windows, macOS or Linux if Flutter and Android SDK are correctly installed.
Do I need an AAB for Google Play?
Yes, Google Play commonly requires Android App Bundle files for app publishing. APK files are better for testing and direct installation.
Are Wrapply Android builds signed?
Wrapply can generate signed APK and AAB files. If you rebuild the project independently, you may need to configure your own signing key.
Can I modify the Android app after generation?
Yes. If you have the Flutter source code, you can update UI, navigation, icons, package name, permissions and integrations before rebuilding.
