Total newbie question.
Tl;dr - Can a progressive web app be registered as a share option in Android?
In Android, we can “Share” things to other installed And
Yes. Now, you can do it on Chrome for Android from version 71+.
Assuming you have all the basics of PWA nailed down (HTTPS, registered service worker, and manifest) you only need to add the following section into your manifest.json:
"share_target":
{
"action": "/share",
"params":
{
"title": "title",
"text": "text",
"url": "url"
}
},
I wrote a more detailed tutorial if you get stuck at any stage.
