Which file configures how the web app behaves when added to an Android user's home screen?

• A. index.html
• B. package.json
• C. manifest.json
• D. serviceWorker.js

Answer: (C)

The file that configures how a web app behaves when added to an Android home screen is the manifest file, typically named manifest.json. This Web App Manifest tells the browser and the OS how the app should appear and run when launched from the home screen. It defines things like the app’s name, icons (used for the home screen launcher at different sizes), start URL, and display mode (for example, standalone or fullscreen), as well as colors for the splash screen and UI chrome. The manifest is linked from the web page with a tag like rel="manifest", which is how the browser knows to use it when the user adds the app to their home screen. Index.html is simply the main HTML document that loads the app’s content. package.json is metadata for the project used by tooling and package managers, not for runtime presentation. serviceWorker.js handles background tasks like caching for offline use, but it doesn’t control how the app looks or behaves when launched from the home screen.
