Is there a way to detect if app was installed with Market or not?

Question

I am wondering if I am able to detect if my application was installed with Android Market (it's in the download list of the Market and eligible for update checks) or it's not?

It would be a very good point to detect if the app has been installed without, as that can mean it was stolen and installed from SDcard.

Answer 1

If you're not root (and have access to Market database), I don't think it's possible.
