Sam's Teach Yourself Android Application Development in 24 Hours. We think this is a particularly good excerpt, too, as it has broad topic coverage.
This excerpt, from Hour 3, covers topics from application design to resources to Android Activities. And then it goes on, and covering Activity lifecycle and even Intents and various things you can do with them as a developer. You even get information about debug logging. It's not just a preview of Hour 3, it's nearly the whole chapter.
