Nov 8th 2020 UPDATE:
Still working intently to finalize the books for Android 11. Also aiming to have both Vol I & II out together, possibly as soon as this month (the 60% thicker volume I is about ready, but I shudder to release it again without the highly anticipated Volume II).
Meanwhile, you might want to check out the Table of Contents, as well as updates I've made to jtrace, imjtool, and the slowly expanding Android Device Database.
As I've said before - If I needed more motivation to throw myself into it, COVID-19 sure provided it.. This is happening, and this year. Till then, stay healthy, y'all.
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 sale (and it's free in PDF anyway, below!) until it is ready.
03/10/2017: Important announcement:
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 Though by now a bit outdated, it's still a high quality, color PDF updated for Marshmallow PR1, and is about 85% the same as the existing book I provide, which is updated to Nougat 7.1 -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.
Right here ←
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!
