[META] App-Links: handle intent

[vesta0]

User Problem

-User taps on a "download/get this app" link on a site.
-They are taken to the Google Play Store mobile site within Fenix with no "open in app" option to open Google Play Store native app
-As a result, user will first need to sign into their Google account.
-If they have the app installed, they will see an "installed" button but still no "open in app" option (although the "open in app" option often shows up if user taps on the "installed" button once)
-If they don't have the app installed, they have to tap on "install", choose which device they want to install the app to, and still not have an "open app" option after installation has been completed.

*Fennec surfaces the "open in app" badge allowing user to open the Google Play Store App but it's not perfect/consistent either. We should support better integration with Android system overall. This is important for browser usability.

User Stories:

• Setting to always open intents in Fenix Setting to choose how to open app intents #7099

Dependencies

• AC turn on app links

Check the test links on this page: https://simonmarquis.github.io/Android-App-Linking/
No app installed - they should redirect to the playstore page.
When the AppLinks app is installed, they should open the link in the app.

This is implemented as part of ac#3058.

The GetAppLinkRedirect use case has a includeInstallAppFallback flag in its constructor.

Blocked by #3358 .

I imagine this is the same scenario, correct?

E.g, I visit Pinterest.com, I see the 'Get on Google Play' at the bottom of their sign-in. Tapping it does nothing currently (52850fe).

Yes @AaronMT , once we reenable the app links feature, that should work

I visit Pinterest.com, I see the 'Get on Google Play' at the bottom of their sign-in. Tapping it does nothing currently (52850fe).

Where the page is directing the user directly to Google Play, this will be handled by a market:// link – which is enabled by ac#3725.

This is blocked by ac#3687.

@rocketsroger what's the word on the GV regression?

@rocketsroger what's the word on the GV regression?

The GV regression was fixed. But the fix introduced a new API that A-C will have to hook into for it to work. I've put up a change to hook into the new API. mozilla-mobile/android-components#7047.

@rocketsroger can we close this now?

@rocketsroger can we close this now?

Yes, I think so. I don't know any open issues related to this.

@vesta0 This still seems to happen for a number of users. see the recent web-bugs.
