Is there a way to sign my app so the user doesn't have to check unknown sources?

I am not planning on releasing my app through the market, however I also do not want the user to have to check the unkn开发者_运维问答own sources to be able to install it. Is there some way of signing it where I can avoid it or another work around?

The 'unknown sources' refers to anything not in the Market. I have never heard of any way to get around it.

Not that I know of.

"the market" is the only valid "known" source, and everything else seems to need the check.

I don't believe its possible unless you push them to the phone with ADB.
