I own a copy of Manning’s ‘Unlocking Android’, which I believe is getting outdated quite quickly. Sure, the general principles still apply but every developer hates the feeling of spending time on something that may be outdated.
I came across this website, a companion website for three highly-rated books on Android. The author behind it did something I haven’t seen before. He offers an annual subscription for $40, that allows you access to his three books and get updates to the books at no extra charge. The Android platform is evolving at a high pace so the updates you get for those 40 dollars are really useful.
Count me in.
