How to launch a app from chrome mobile browser before opening a page?

The problem I faced with is as follows.

I need to launch an app before opening a page using chrome mobile. I use the URL scheme to do that. It was valid in some browser like Opera Mini, but failed in chrome mobile.

I also try iframe.src and window.location, and Intent to achieve that (chrome has explain somthing to us: https://developer.chrome.com/multidevice/android/intents), but only by adding a element to page and letting user to trigger the event can I launch the app.

If someone can give some suggestions? Thanks very much.
