Working full steam on the rewrite - Android 11 preview just came out, so rest assured the book will be up to date! Lots of updates, O(100) new pages now. If I needed more motivation to throw myself into it, COVID-19 sure provided it..
Please do not send money for the older edition anymore - It is effectively out of print. The revised edition will, in effect, be an entirely new "second edition", so I am suspending the first edition until it is ready.
Volume I rewrite nearing completion, to accommodate changes up to and including Android 10, as well as new topics (TrustZone) and devices (Huawei, S10, etc) which didn't exist five years ago. Volume II also advancing rapidly.
As some of you know, The WikiLeaks dump of "Vault7" contained, among other things, a 2015 copy of my "Android Internals" book, since Technologeeks provided training for them. Though by now a bit outdated, it's still a high quality, color PDF updated for Marshmallow PR1, and is about 85% the same as the existing book I provide, which is updated to Nougat 7.1 - Android changes rapidly, but the core isn't radically different.

I will still sell the updated book, though I'm slashing the price to $15. So if you want to get the updated version (or just show support), you can still buy it as before , by Paypal to confectioners at this website - but at half price. If you get the hardcover book on Amazon you will also see I discounted the price to $50 (print costs and Amazon fees are exorbitant).
NO, I cannot retroactively refund everyone who bought the book, but I do thank you for respecting the insane amount of work I put into it, and not releasing the PDF publicly. I will still maintain updates for whatever Google concocts with Android O, and naturally all my tools will remain free.
I hope you enjoy the book, and encourage you to look at the Technologeeks Training we offer on it. And thank you all for your interest!
