All three books will be updated over the next several weeks, with two
being updated within about 10 days. The original Android book will take
longest, mostly because I want to get the other two in print.

You can do that yourself, with full control, without having to launch an
external activity, via the Camera object. _The Busy Coder's Guide to
*Advanced* Android Development_ has a chapter on this, and that should
be brought up to Android 1.5 in ~10 days.
It's not that hard, once you have the recipe, and then you have full
control over the user experience.

I stand by my recommendation: use the Camera object and take the picture
yourself. If you need MediaStore to know about the picture, I'm sure
there is some way to do that (e.g., call insert()).
