问题 It's been now a long time since I try to figure out how to develop a android unlock screen app working with an NFC authentication. I am working with a Nexus S. After several researches on the Internet, I came to the conclusion that replacing the lock screen as a third party app is just not supported right now and that we need to modify the platform to do a decent implementation. This is the reason why I developed an home screen app that give the illusion of an unlockscreen app. But my problem

问题 I'm trying to create an "Add To Home Screen" button on my progressive web app, as described in Chrome's documentation. I'm generally following the prescribed pattern, where I have some hidden button which is displayed when Chrome's beforeinstallprompt event fires. I capture the event once it fires, and then use the event to begin the native install dialogue once my own install button is clicked. The sample code is below: let deferredPrompt; window.addEventListener('beforeinstallprompt', (e) =

问题 Can someone tell me how to check that my widget have been placed on the homescreen? I have some code in my app that should run only if the widget is placed on the homescreen. 回答1: You need to store that information yourself.
