*You* probably can't if you have to ask, but in general that should be possible for an decent programmer with sufficient time.

according to how you worded you own question, no.

But, according to people who know what theyre talking about, yes. adjust the min sdk target.

You'll have to adjust the min SDK target and you'll have to make sure that you don't use any API's above that of 2.3.4 . If you do, either pray there is a support library available for it, or just remove/rewrite it.

Many Thanks,

Ok, I need an IDE to do this,..right?,..any suggestions?,...and also how do I find out if there is any function or API in the source code that is not supported by Android 2.3.4? ... IDE warns me?

Don't remember whether Android 4.0 supported Android Studio projects yet, but download it anyway. Then once it's downloaded, use its "import project" function for it to generate a project out of the already existing code.

no. An IDE is just a test editor with a compile button. Literally not needed in any programming project.
