Hello
I found a good example of a camera (Thanks Erado). It has a small Class which extends Activity and the main business is in class PreviewView extends SurfaceView implements SurfaceHolder.Callback, AutoFocusCallback {
etc etc}

In the original example the his Activity is the main. However I would prefer to implement it as an activity called by an Intent, and returning to the onActivityResult in my main Activity.

In other cases I've used this.finish(); to return from an activity started for result. I cannot figure out how to exit this class. It goes round and round nicely taking and storing photos for every click, but I want it to stop after one and return to the main caller to decide what to do next.

Thanks
John

In order to return to the caller of your activity (and return some values to it), you would do something like this:
