Volume I now in v2.2 - cover reflects COVID being behind us (and updates for Android 13). Volume IV indeed nearing completion, III will take more time (but I'm on both).
Working in parallel on Vols III and IV. At this rate IV (spun off from II) is nearer to completion.
Going live April 1st - no joke! If you buy the book on Amazon Please use this link so I can get back commissions!
Vol II is ready, and first copies ship by
end of this month mid/early March to the dozens who preordered! Thank you SO MUCH for believing in me. Sorry for delay, but upside is I'll be up to date with Android 13 DP :-) Details here. Amazon orders will open up shortly thereafter!
Volume I is now in v2.1 - fully in sync with Android 12 (per the Pixel 6). Meanwhile, work on Volume II is nearing the finish line, but the finish line has moved a bit further with more features to cover...
The second edition of Android Internals is now officially live! The new and improved volume I is now on sale (just six years later ;-) Added well over 240 pages from previous edition (effectively, double size), with expansive coverage for filesystems/storage, slots/update_engine/apex, logging, power mgmt, and a hardware primer noting BSP/vendor differences
to follow soon is done, done, DONE (really, this time). Also far greater than the original (and forever delayed) plan, with a strong focus on hardware (HAL implementations) and Android 10, 11 and 12 and some 13 features.
Volume 3 (yep!) dealing exclusively with security to arrive sometime around mid-year.
Jury's still out if I follow the model of MOXiI 3 and show I will be discussing actual (but naturallly patched) exploits. If you have any good Android malware samples, though, that's a shoe-in for inclusion, so please share!
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. I've also started a changelog.
"Android Internals: A Confectioner's Cookbook" is a new book by Jonathan Levin, author of "Mac OS X and iOS Internals: To The Apple's Core". It is the first book to deal exclusively with the internals of the world's most popular mobile operating system. Like the OSX/iOS book, it provides an unprecedented level of detail on previously undocumented subjects, illuminating the darkest corners of the Android frameworks, native libraries and kernel.
If you are a power user, developer, kernel hacker or Android implementor - this is the book for you. An odyssey in three volumes, each focuses on a different perspective of the system. The architecture is explained through the use of detailed diagrams, examples and interactive experiments. Input, Audio and Video architectures are covered in dedicated chapters, as well as security. The necessary Linux foundations, especially in kernel mode, are also detailed.
