Integrating your app with google voice

I am a student developer working on a hands free texting solution for android. After much hard work, the app is finally complete and has been released on the market. However, the very first review I got from a user was a request for google voice integrati开发者_JS百科on.

Is there some way to integrate my app with voice? Is there a broadcast receiver or something that I could implement, and a way to send texts? After much googling, I an still unsure where to begin.

All that I need to be able to do is receive text messages from voice and then send out new ones in reply.

There is an unofficial Google Voice API for Java. There are also example apps.
