This has been used in Android since 1.0 by apps like Market, YouTube, and Gmail to allow the user to select to go to the app which clicking a link from the browser. The sample code I showed is the actual code in Market. This definitely does work, on every version of Android.
Re: using custom schemes -- it is fundamentally broken to randomly define new schemes that appear on web pages, because schemes are a universal namespace so it is extremely easy to have conflicting schemes with had results. This is why on Android we strongly recommend intercepting URIs based on real web site URIs. This also allows decent graceful fallback for the case where there is not an app that knows how to intercept the URI -- the URI can still be shown as an actual web page, with whatever you want including instructions on how to download and install your app. If iOS doesn't support this... well, I can't make them allow for a non-broken way to do this. :} Android *does* allow you to intercept just by scheme, we just discourage this because it is fundamentally flawed.
