I'd prefer 2.

One additional request with 2 is that you allow us to append Google Install Referrer params to the intent, or carry them through the web link. (related to this issue https://bugs.chromium.org/p/chromium/issues/detail?id=459711 where S.install_referrer was added)

Bump. We are currently in this failure scenario and looking for a fix. As for the proposed solutions, keep in mind that this issue also occurs when the user chooses to launch a url from the 'Open in new tab' long press option, which might make Option 1 less of a catch all.

Bump!!!!

I have a plan agreed with security team, for play.google.com fallback URL only to redirect to the play store instead of the play webpage. Will be making this fix in M-57.

Great! What's the ETA for this to hit production Chrome so we know when to update our code?

Load Market App for Fallback URLs.

When handling a fallback URL for an app because the app is not
installed, if the app developer specified Play Store URL as a fallback
URL, then take the user to the Play Store App instead of loading the URL
in the browser.

The ETA for this to hit production is March 2017. The fix should be available on Chrome Canary in a day or so if you want to test it out.

Specifying fallback URL to be https://play.google.com/store/apps/details?id=<package>&referrer=code should redirect you to the play store app with the specified referrer.

You rock. Super pumped for this to not be so ghetto.

Redirect to play store app for web play store URL fallback.

A fix for the initial implementation in
https://codereview.chromium.org/2595773002/ where we would only redirect
to play store in one of the cases where fallback URL is used. Move the
code to the general path for clobber instead.
