Camera application template for Android

I am looking for someone to create an Android application template (compatible Android 3.0 and later). The application will open the camera, and display the preview on the screen. It will allow me to add some code to process the frames that are being displayed - meaning I need to be able to modify the images on the go. It should be fast (i.e. check for the runnning Android version and use the best possible code available for each version - I know that Android 4.0 has more functionality around this)
