Android calculation app

The winning bidder will code a very simple and basic custom Android calculation app that we've developed using all of our own graphics, background, logos, layout, and screen mockups that we produce as the model for the finished app. We've done the Android app mockup in Android App Inventor. What we need is someone to code the app using Eclipse so that we can then add banner ad code to the finished app on our own, which Android App Inventor will not allow. The finished app code will be wholly owned by us, as will the intellectual property related to the Android app.
