Hi guys i recently add notification on my android app webview so i think i should share. There is this extension Syndication by @AmauryPi which add rss feed on a flarum you can use this to generate notification using Zapier Rss to OneSignal then if your using Android webview you can add App link on your app so that when a user click the link it will take him/her to specific page. You can choose which notification you want user to get by using specific link from Syndication extension.
/atom: feed with the last discussions with activity (the /all page as an Atom feed);
/adom/d: feed with the newly created discussions in the forum;
/atom/t/tag: feed with the last discussions in the given tag (the /t/tag page as an Atom feed);
/atom/t/tag/d: feed with the newly created discussions in the given tag;
/atom/d/21-discussion-slug: feed with the recent posts in the given discussion
There is this webview which is best and it can even handle google sign up but it not loading well on flarum, if you can find the solution for this this will be very cool. The app is on github and this is a link to it mayursojitra/Web-Mobile-App
