Marketlauncher is a project mainly written in Java, it's free.
Small Android helper app to launch market client from browser links
A small helper application, intended to open Android Market URLs from a browser (which normally they refuse to do).
Registers to handle urls in the 'marketlauncher:' scheme from the browser. Checks for URLs of the form 'marketlauncher://details?id=...' or 'marketlauncher://search?q=...' and creates an intent with the equivalent 'market:...' URI and calls startActivity on it.
Note that the emulator doesn't have a Market client (typically).
