It will also help take the pressure of informing a user that they are on a PWA off the app install banner, allowing that feature to be evolved to allow more developer control.

commit 203b49362f2a10176bd12346f116266622316913
Author: Dominick Ng <dominickn@chromium.org>
Date: Fri Feb 02 05:32:45 2018

Implement a PWA ambient badge behind a flag.

This CL implements a mini-infobar that is displayed when users visit any
PWA. Tapping the infobar will trigger add to home screen. The intention
is to inform users that they are browsing a PWA, give easier access to
add to home screen, and encourage developers to adopt PWAs through
privileged UI.

App install currently fulfill the informational role that ambient badges
will now take. This CL will enable future work to stop app banners from
automatically appearing, and change them to adopt a modal,
developer-triggered flow which hands more control to sites.

Future CLs will:
 - disable automatic app install banner triggering when the ambient
   badge feature is active
 - change the string of the ambient badge such that it launches the PWA
   if it is already installed

Eventually, it is hoped that a less intrusive UI will take the place of
the mini infobar for the ambient badge.

Should we split this off into a separate bug for DPWAs or just reuse it?

Let's split this for DPWAs and leave this one as Android-specific.

  https://chromium.googlesource.com/chromium/src.git/+/a428757cace3ba6571abc23f41947fcc92c7415f

Remove the CheckInstallabilityForBannerOnLoad feature.

This CL replaces mentions of the CheckInstallabilityForBannerOnLoad
feature with ExperimentalAppBanners, consolidating the feature flags for
the new app banner flow.

Once the modal banner UI and ambient badging changes on Android land,
this CL has the additional effect of ensuring ambient badge checking
will start as soon as the load event dispatches, rather than when
sufficient engagement to trigger the banner is earned.

commit a32333e7b6248fe973ac434d918b83226acf138d

Display an ambient badge for sites advertising a native app installation.

This CL shows ambient badges for sites offering native app banners when
the ExperimentalAppBanners feature is active. This is in order to
retain the ability to subtly advertise a native app and disincentivise
door-slam app install interstitials following the conversion of app
install banners to user-triggered modal dialogs.

With ExperimentalAppBanners active, no app banners are automatically
shown. Instead, sites that are eligible for banners will display an
ambient badge (currently a mini-infobar on Android) that triggers the
modal banner when tapped. This is a slight behaviour change for the
ambient badge (it previously triggered add to home screen directly;
now it triggers the banner). This allows users an additional
confirmation step before installing a native app, and keeps consistency
between web and native.

The site may also use the JavaScript beforeinstallprompt API to
trigger the app install banner directly. A follow-up CL will dismisss
the ambient badge when the app install banner is triggered in this way.

Search has been downranking sites showing app install interstitials, and
app install banners have been advertised as an alternative. With the
conversion of app install banners to modal, this CL retains the ability
for sites to use the same mechanism for app install banners.

This CL also renames the PwaAmbientBadge*Android classes to be called
InstallableAmbientBadge*. The Android suffix is removed as the infobar
header is included and compiled on non-Android platforms in order for
AppBannerManager to fulfil the
InstallableAmbientBadgeInfoBarDelegate::Client interface, which is
needed to avoid a duplicated WeakPtrFactory on AppBannerManagerAndroid.

When the ExperimentalAppBanners feature is active, sites with an
installable app (PWA or native app) display an ambient infobar to
inform users of the app. This CL dismisses the ambient badge
infobar if the site shows a modal app banner, as the ambient
badge and app install banner both link to an add to home screen
action.

Improve the interaction of the installable ambient badge and app banners.

This CL restructures the app installed check for app banners to run
after banner eligibility is checked, but before engagement is checked.
This allows the Android subclass to dispatch the installable ambient
badge as soon as eligibility is established, rather than waiting until
sufficient engagement is earned. It also allows the text of the badge to
be changed based on whether the app is installed ("Open in app") or not
("Add to Home screen").

This CL also:
 - adds functionality to open the web app from the ambient badge
 - ensures that trying to trigger the banner after installing from the
   ambient badge is a no-op (edge case)

Launching this has been a mess due to the PM swap. We're aiming to have a launch bug filed today.

Requesting merge of #15 to M67 branch 3396. This is a flat revert of #12 since we are punting the launch of this feature by 1 milestone. It should be very safe to merge since this state was on trunk for a long time prior to #12 landing, and there have been no relevant changes in the interim.

This bug requires manual review: There is .grd file changes and we are only 38 days from stable.
Please contact the milestone owner if you have questions.
Owners: cmasso@(Android), cmasso@(iOS), kbleicher@(ChromeOS), govind@(Desktop)

There are no grd changes in #15 (thanks sheriffbot)

Do not show the PWA ambient badge for installed apps.

Feedback from UI review is that this is intrusive (e.g. having Twitter
Lite installed as a PWA, but still viewing tweets in the browser).

Hide the ambient install infobar for 90 days if it has been dismissed.

This CL reduces the annoyingness of the ambient badge infobar on Android
when browsing a PWA. If the infobar is dismissed, it will not be shown
for 90 days, mirroring the existing block time for infobar app banners.
The infobar will continue to be shown on navigations until it is
dismissed.
