How It Works

1. Host an update.json file on your server with the latest version info, changelog, and APK URL.
2. Add InAppUpdateManager dependency to your Android app.
3. Configure the URL pointing to your hosted update.json.
4. The library checks for updates at app launch or periodically, shows the update screen if a new version is available, downloads the APK, and manages installation with progress tracking.
