I have just finished reading the content, so here what I say about it:
First of all, I am an android developer with 3 years experience. That is why I will divide it into two categories:
a) newbies
I highly recommend you to buy it, of course, if you can. You will get most of the information in the wesite with experience in couple years, but it is better if you get them now. It will help you a lot. I remember, first several months of my development I was earning near to 0, probably it will help you avoid it. Especially now, when it is really hard to get ranked in GP, big apps get all the downloads. And the app source codes will help you to learn android development by looking on a working project.
b) developers with experience
If you have over 2 years of experience, you probably know most of the stuff, but still you will get some new information that can boost your apps. In my case, I am already planning to use 2 of the suggestions from the book in my next apps.
Don’t know about autotranslator, haven’t used it yet, but if it works, then it is great
