Android Market Intent

Hello, I am in need of a complete working example of the following. This example will create a ListView of Android market urls using Android app namespaces. Upon the selection of a ListView item, an Android Intent is to be initiated. This intent is to return to the Android market details for immediate download and installation by the user. The result needs to be compliant with the current Android sdk for Android releases 1.5 thru 3.0 in both the portrait and landscape modes. All code, text, html, css, etc, for the project need to be well commented for functionality and usage. In summary, I would like the user to be able to click a button in an Android app and have this project example display a Listview with list of apps names when clicked/touched, present the user the "Install" option of the selected app from the Android market. Thanks for your help.
