And since Blake was too shy to mention his own web site and book, let me do it for him;) The coverage of these issues in "Programming Android" is better than in many Android books, and in his webcast "Concurrent Programming in Android" is even better.
IntentService is so handy, I am amazed it got so little coverage in Android Developer documentation all this time. Even with the vast improvements in the 4.0 docs, IntentService is still under-documented. There is a lot you can do with either this or Looper/Handler without having to resort to AsyncTask, which really has been over-billed in recent years as if far more flexible and useful than it really is.
