I have used

As stated in the ments there are security and privacy reasons surrounding why you are not able to do what you are asking.

However, @CommonsWare, has already given a workaround to this problem, in a similar question, that has already been asked:

Fortunately, this is not possible, for obvious privacy reasons.

The closest that you can do is in the application, have an activity that has an for some URL structure, and have a link in the mobile Web site to a matching URL.

If the user clicks the link and the app is installed, the activity will be a chooser option for the user.

If the user clicks the link and the app is not installed, or they choose to stick with their Web browser from the chooser, whatever Web page exists at that URL will be displayed (E.g., instructions of how to download the app).
