This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Do you detail and give example of the Android service/activity lifecycle in your book ?
I find the "singleTop", "singleTask" very confusing in Android. I still don't understand how to have 2 activities in background and put them on front when needed instead of create a new instance.
