I have experience programming in BASIC, HTML/javascript, C, and Java, and I was looking to start programming for leisure in Android. There were so many Android books on Amazon that I decided to bookmark some of them and ask you guys. The ones I bookmarked are: "Hello, Android" (Burnette), "Beginning Android" (Murphy), Pro Android (Komatineni, Hashimi), and Professional Android 2 (Meier). Are any of these books recommended or are there others not on this list that you're willing to suggest?
