Detect if the user rated the app in Android

Question

Recently I read a article about a game in the market (I won't give the name because I think it that practices are negative for Android and don't want to publicize it) that don't allow to update if you have not rated 5 stars in the market.

Thats what the article says and I'd like to know if that is detectable and if yes how to do it (I only need to know if the user rated the app, don't need the score)

Thanks

This is not possible as described. An application cannot prevent itself from being updated. Now, it is possible that it can detect the update when it is next run and then take some action.

There is no documented and supported means of doing this. I'll be stunned if it is possible outside of rooted phone -- it's a security flaw otherwise.
