I need modify start page of my website. It should identify if user view webpage using Android smartphones and then it should display message with redirection to our custom Android Application.
Website: [login to view URL] - this is page for food ordering that is not optimalised for smartphones and we want to redirect users on Android Smartphones to download our custom app for food ordering. If app on smartphone is already downloaded and installed the webpage should not redirect to download but shoud open it.
It should be something like Netflix - when You wabt enter [login to view URL] webpage on smartphones it automatically opens Netflix Application.
