Game Beaver | Windows Desktop App to Convert HTML Games into Android APK and AAB

Turn Any HTML5 Game into a Signed Android App – No Coding Required

GameBeaver is a Windows desktop application that converts a ready-made game template or your own HTML5 game folder into a fully signed, production-ready Android APK or AAB in six guided steps. No Android Studio. No command line. No experience needed.

• Windows 10 and 11 desktop app
• Outputs a Signed APK (for sideloading) and a Signed AAB (ready for Google Play)
• Ready-made HTML5 game templates with search, categories and live preview
• Upload your own HTML5 game folder – packaged fully offline inside the app
• AdMob ads integration (banner, interstitial and rewarded) for instant monetization
• Built-in build tools – everything downloads automatically in one click
• Auto-generates and manages your Android keystore

What is GameBeaver?

If you have an HTML5 game – or you simply want to launch a mobile game without building one from scratch – you can now package it as a real Android app and distribute it on the Google Play Store or share it directly as an APK file, all without writing a single line of Android code.

GameBeaver handles everything behind the scenes: it downloads and manages the Android SDK, JDK and Gradle automatically, generates your signing keystore, compiles your game, and hands you a finished .apk or .aab file ready to ship.

The same tool that takes a professional developer hours to set up – done in minutes.

Key Features

1. Ready-Made Game Templates

Not sure where to start? Choose from a built-in library of ready-made HTML5 games. Search by name, filter by category, and press Preview to play any game in a phone-shaped window before you select it. Picking a template fills in your app name for you.

2. Upload Your Own HTML5 Game

Browse to a folder on your computer that contains your game and an index.html file. The whole folder – HTML, CSS, JavaScript and assets – is bundled into the app, so your game works fully offline.

3. Six-Step Build Wizard

A guided wizard walks you through Choose Game, App Identity, Game Settings, Monetization, Signing and Build, and finally Build and Download. Click any step in the left panel to jump back and change something at any time.

4. One-Click Build Tools Download

No need to install anything extra before you start. GameBeaver downloads and sets up Java, the Android SDK and Gradle automatically, once, and keeps them ready for every future build.

5. Signed APK and AAB Output

Every build produces a release-signed output. Choose either or both:

• APK – install directly on any Android device, perfect for testing and sharing
• AAB (Android App Bundle) – the required format for uploading to the Google Play Store

6. Auto Keystore Generation and Management

A keystore is a security certificate that proves the app belongs to you, and Android requires one for every app. GameBeaver creates it for you automatically from the alias and passwords you enter. If you are updating an app you have already published, you can use your existing keystore instead. A built-in Download Keystore button lets you save a backup copy at any time.

7. App Branding – Icon and Splash Screen

Upload your own app icon (512×512 PNG) and a centered splash logo (for example 512×512 PNG). Both are optional, so you can start building straight away and add branding later.

8. Game-Focused Settings

Control exactly how your game behaves on the phone with simple switches:

• Screen Orientation – auto-rotate, portrait or landscape lock
• Fullscreen Mode – hides the status bar and navigation bar, with swipe to reveal
• Keep Screen Awake – the screen never dims or locks while playing
• Block Zoom and Text Selection – disables pinch-zoom, double-tap zoom and long-press menus
• Exit Confirmation – asks “Exit game?” when the Back button is pressed

9. Granular App Permissions

Choose exactly which Android permissions your app declares. All are off by default, because most games need none of them:

• Camera
• Microphone
• Location (GPS)

10. AdMob Monetization

Monetize your game immediately with Google AdMob. Enter your AdMob App ID and ad unit IDs for:

• Banner Ads – shown while the game runs
• Interstitial Ads – full-screen ads at natural breaks such as between levels or on game over, shown at most once every 60 seconds
• Rewarded Ads (optional) – let players watch an ad to earn a reward such as a hint or an extra life

Do not have an AdMob account yet? Use the built-in Auto-Fill Test IDs button to try ads safely before going live.

11. Real-Time Build Console

Watch your app being built in real time through a built-in console with a live progress bar. If anything goes wrong, the console shows exactly which step failed so it is easy to fix.

12. Save and Open Projects

Save every setting of your app to a single project file and open it later to rebuild or update without re-entering anything. Keep project files private, as they may contain your keystore details.

13. Fast Build Mode

Enable Fast Build Mode to skip saving the full Android project to disk. The app outputs only the final APK or AAB, saving disk space and build time.

14. Android Version Targeting

Choose your Target Android Version (Android 12L to Android 16, API 32 to 36) and Minimum Android Version (Android 5.0 to 8.0) to control device compatibility and Play Store target requirements.

Who Is This For?

• HTML5 game developers who want to ship their game as an Android app without learning Android development
• Freelancers and agencies who want to deliver mobile games to clients without hiring an Android developer
• Indie creators who want to launch a game on the Play Store quickly and earn from AdMob ads
• Beginners who want to publish their first mobile game with no coding knowledge
• Digital product sellers who want to add Android games to their product offering
• Educators and hobbyists who want to turn their HTML5 projects into installable apps

How It Works – 6 Simple Steps

1. Choose your game. Pick a ready-made template, or browse to your own HTML5 game folder.
2. Set your app identity. Enter your app name, package name, version name and version code, and optionally upload your icon and splash logo.
3. Configure game settings. Set orientation, fullscreen and the other switches, and turn on only the permissions your game needs.
4. Set up monetization (optional). Add your AdMob IDs, or skip this step entirely.
5. Set up signing and output. Let the app auto-generate a keystore or use your existing one, enter your store password and key password (minimum 6 characters each), and choose APK, AAB or both.
6. Click Build and download your files. The build runs with a live console. When it finishes, open your APK or AAB straight from the Your App Files list.

Important AdMob and Google Play Developer Account Notice

Users are solely responsible for complying with all applicable AdMob policies and terms, as well as any costs, fees or revenue-sharing arrangements associated with AdMob or other third-party services. These conditions are determined by the respective service providers and may change.

To publish applications on the Google Play Store, users must have a Google Play Developer account, which requires a one-time registration fee payable directly to Google. This fee is separate from the GameBeaver purchase price.

Frequently Asked Questions

Do I need to install Android Studio or any other software manually?

No. GameBeaver downloads and sets up everything it needs the first time you use it. Just install the app and click one button – it handles the rest.

Do I need to know how to code?

No. If you use a ready-made template, you do not need to write any code at all. If you bring your own game, it only needs to be an HTML5 game folder with an index.html file.

Can I publish the app to the Google Play Store?

The Play Store requires the AAB format, not APK. GameBeaver outputs both. Build your game, take the .aab file and upload it to your Play Console. A Google Play Developer account (one-time fee) is required, and you should check Google’s current target version and policy requirements before you publish.

Can I use my own game?

Yes. Choose Upload My Game and browse to the folder that contains your index.html. The whole folder is bundled into the app, so it works fully offline.

Does the finished game work offline?

Yes. The game itself runs fully offline. An internet connection is only needed for license activation, the first-time tools download, and for ads.

What happens if I lose my keystore?

Without your original keystore you cannot publish updates to an existing Play Store listing. Always use the built-in Download Keystore button after your first build and store the file and passwords somewhere safe. The app cannot recover a lost keystore.

Can I use my own existing keystore?

Yes. In the Signing step, choose Use Existing and browse to your .jks or .keystore file. Enter the same alias and passwords you used when the keystore was created.

Is AdMob required?

No. AdMob is completely optional. If you do not want ads, leave the AdMob switch off and no ads will be included.

Why do I not see real ads in my test build?

Test IDs show fake ads and earn nothing. Replace them with your real AdMob IDs before you publish. New AdMob ad units can also take a few hours to start serving, and rewarded ads only work in the installed app, not in a normal browser.

What is Fast Build Mode?

When enabled, the builder outputs only the final APK or AAB files without saving the full Android project folder to disk. This saves disk space and slightly speeds up builds.

Can I update my app after publishing?

Yes. Increase the Version Code by 1 (for example 1 to 2) and optionally the Version Name (for example 1.0.0 to 1.1.0), then rebuild with the same keystore. Upload the new AAB to the Play Console as a new release. The package name cannot be changed after you publish.

What Android versions does the output app support?

By default the app targets Android 16 (API 36) and supports devices back to Android 7.0 (API 24). The minimum can be lowered to Android 5.0 (API 21) in the build settings.

Is my license tied to one computer?

Yes. Your license is tied to the device where you activate it.
