What is PWA and Share Target API?
PWA (Progressive Web App)
is a web app that can be installed on the home screen, works like a native app, but without a store installer.
Share Target API
allows the PWA to open in response to a "Share" action from Android – meaning when you choose "Share" for text or a file in any app, you'll see qrr.app as a target.
