I am trying to do deep linking such that when someone opens a link from mobile browser, it either opens the app, if it is installed or opens the play store link to download the app.
Here is my URI :
intent://scan/#Intent;scheme=com.example.android;package=com.example.android;end
When I type this in Mozilla Firefox app on Android, it opens my app if it is installed or opens the play store link if it not installed. But, when I type the same thing in Chrome, instead of opening app or play store, it just does a google search. What is wrong with my solution and how do I make it work?
This is a known wontfix
bug in Chrome 40+ (see the Chromium project ticket here for the full story).
Essentially, the Chrome team feels that if a user actually types something into the address bar, no redirect should ever happen. As you've discovered, this is counter to behavior in all other browsers.
Fortunately it's unlikely a user would actually type an intent://
URI by hand. If you wrap the URL inside a link on a webpage, or offer a link to another page and then issue a redirect of some kind (so that you can detect the user agent and not show a 'broken' intent://
link to users on other browsers), it should work correctly.
If you don't want to handle all these edge cases, you could also try a free service like Branch.io (full disclosure: I'm on the team).
