Universal App Builder for Windows

AndroCity is a Flutter-based Windows desktop application for configuring and building Android applications from websites, video playlists, and local HTML projects.

Create and manage multiple Android app projects from one Windows workspace, configure the app content, customize the generated application’s icon, splash screen, colors, navigation, and other settings, configure Google AdMob, manage Android signing, and generate APK or AAB packages.

What Is AndroCity?

AndroCity provides a Windows-based workflow for creating configurable Android application projects without manually starting a new Android project for every supported app type.

The application currently supports three Android app generators:

• Website → APK
• Video Playlist → APK
• Local HTML → APK

After creating a project, you can configure its content, visual design, monetization, Android version information, signing configuration, and build options before generating the Android package.

Core Features

• Windows desktop application built with Flutter
• Local project management
• Website → APK generator
• Video Playlist → APK generator
• Local HTML → APK generator
• Visual App Designer
• App icon customization
• Splash screen customization
• Theme color customization
• Bottom navigation configuration
• Side menu / drawer configuration
• Google AdMob configuration
• Android version name and version code management
• Custom Android keystore generation or existing keystore selection
• Release signing configuration
• APK building
• AAB building
• Build logs and generated-file path display
• Managed Android build environment
• Project backup and restore
• Generated Android source templates

1. Website → APK

The Website generator creates an Android application around a website using the included Android WebView-based template.

Website Configuration

• Website URL
• Enable JavaScript
• Pull to Refresh
• Show Loading Indicator
• Open External Links in Browser

The generated Android project includes the required WebView configuration and Android source files. The website itself remains externally hosted and controlled by the buyer.

For production use, test the target website on real Android devices and make sure the website, content, external services, and network requirements are compatible with the generated application.

2. Local HTML → APK

The Local HTML generator allows you to package an existing local HTML application into a generated Android project.

Local HTML Workflow

• Select the root folder containing the HTML application
• Select the entry HTML file
• Package the selected local HTML content into the generated Android application
• Configure JavaScript
• Configure Pull to Refresh
• Configure Loading Indicator
• Configure External Link handling

Relative files contained inside the selected HTML project can be packaged with the generated Android application. The entry path must remain inside the selected project folder.

External services or resources referenced by the HTML application may still require an internet connection when the generated Android application runs.

3. Video Playlist → APK

The Video Playlist generator is designed for creating configurable video and course-oriented Android applications.

You can organize content using categories and subcategories, add individual video entries, configure video metadata, choose video sources, and customize the generated application’s video experience.

9. Google AdMob

AndroCity includes optional Google AdMob configuration for generated Android applications.

AdMob Settings

• Enable / Disable AdMob
• AdMob App ID
• Banner Ad Unit ID
• Interstitial Ad Unit ID

AndroCity validates the configured AdMob identifiers before building when AdMob is enabled.

If AdMob identifiers are left empty, the application uses Google’s Android test identifiers. These test identifiers must be replaced with the buyer’s own AdMob identifiers before production release.

Third-Party AdMob Notice: Google AdMob is an external third-party service and is not included as a paid service with AndroCity. Using AdMob requires the buyer to maintain an eligible Google AdMob account and comply with Google’s current account, publisher, advertising, privacy, consent, payment, and other applicable requirements. AdMob monetization may involve revenue-sharing arrangements, payment thresholds, invalid-traffic policies, and other conditions established by Google, which may change over time. Additional costs may apply to third-party services used with generated applications, and such charges are the buyer’s responsibility. AndroCity does not provide an AdMob account or advertising budget and does not guarantee account approval, ad serving, revenue, or marketplace acceptance. Buyers are responsible for reviewing and complying with all applicable third-party terms and policies.

10. Android App Version Management

Each project includes Android application version settings.

• Version Name
• Version Code

The application validates these values before saving. Increase the Android version code when preparing a new store release.

11. Android Release Signing

AndroCity includes a dedicated signing configuration for Android release builds.

Keystore Features

• Generate a new keystore
• Browse and select an existing keystore
• Enable or disable custom signing
• Store Password
• Key Alias
• Key Password

Signing credentials are handled separately from normal project configuration and are stored using Windows secure storage.

Always keep production keystores and signing credentials securely backed up. Losing a production signing key can affect your ability to update an already-published Android application.

12. Build Center

The Build Center is the main build workflow for generating Android packages from configured projects.

Available Build Formats

• APK — suitable for Android device testing and direct distribution workflows.
• AAB — suitable for Google Play upload workflows.

The Build Center displays build progress and logs and provides the generated output path after a successful build.

• Project generation
• Gradle build execution
• APK generation
• AAB generation
• Build status
• Build logs
• Generated file path
• Copy Path functionality

Generated Android projects and build outputs are stored under the configured AndroCity build directory in the Windows user’s Documents folder.

13. Managed Android Build Tools

AndroCity includes a Build Tools section for setting up the Android build environment required by the generated projects.

The current project documentation specifies the following managed components:

• Eclipse Temurin JDK 17
• Android Command-line Tools
• Android Platform Tools
• Android API 36
• Android Build Tools 36.0.0
• Gradle 8.13

The Build Tools screen checks the environment and reports its current status.

Internet access is required when the managed tools and Android/Gradle dependencies need to be downloaded.

14. Generated Android Projects

AndroCity uses included Android project templates to generate the application source.

The package contains templates for:

• WebView-based applications
• Local HTML applications
• Video player applications

Generated projects contain Android/Kotlin source code, resources, application assets, Gradle configuration, and a Gradle Wrapper.

Generated Android projects can be opened separately in Android Studio when additional Android-specific source customization is required.

15. Project Management

AndroCity stores project records locally and allows you to create and manage multiple Android app projects from the Windows desktop application.

Project configuration includes information such as:

• Project name
• Application type
• Android package name
• Version name
• Version code
• Application icon
• Theme configuration
• Splash configuration
• Navigation configuration
• Monetization configuration
• Content configuration
• Signing configuration
• Video application configuration where applicable

16. Backup & Restore

The Backup & Restore feature allows project records to be exported and imported using AndroCity’s .acb backup format.

Backup Includes Project Configuration Such As

• Projects
• Design configuration
• Settings
• Build configuration
• Keystore configuration

Production signing passwords and keystore files are not included in normal project JSON backup data. Local media and other externally referenced files should be backed up separately.

17. Local Data & Build Locations

AndroCity stores project records and selected-project information in the Windows user’s application data/documents environment.

The current documentation specifies these locations:

• Managed tools: <Documents>\androcity_tools
• Generated projects/builds: <Documents>\androcity_builds

Signing credentials are stored separately using Windows platform secure storage.
