App opens like a link with url bar at the top, rather than like an android app

Describe the bug After installing the generated apk, the app opens like a normal link in the Google app rather than an android app. It has a url bar at the top

To Reproduce Steps to reproduce the behavior: use bubblewrap cli to generate apk using the following manifest:

Note: The links are fake

// twa-manifest.json

    }
  ],
  "start_url": ".",
  "display": "standalone",
  "theme_color": "#ffffff",
  "background_color": "#ffffff"
}

Expected behavior The app should open like an normal android app, without the url bar

Desktop

• OS: Fedora 35 workstation
• Browser: Chrome
• Version: 100

Smartphone (please complete the following information):

Additional context Additionally, the PWA works great when installing from the browser using the install app option from the website. It opens like a usual android app, without the url bar

@SJShip, I just checked it, and I had names the assetlinks.json file as assetslinks.json. I’ve wasted so much time on this because of a small spelling mistake. Unbelievable.🤦🤦

Thanks a lot for pointing it out.

@Pika-Pool , A Trusted Web Activity needs the origins being opened to be validated using Digital Asset Links, in order to show the content in full-screen (without URL bar). Did you provide the /.well-known/assetlinks.json endpoint for your root domain and subdomain with correct assetlinks?
