Android Software Internals Quick Reference: A Field Manual and Security Reference Guide to Java-based Android Components

Use this handy field guide as a quick reference book and cheat sheet for all of the techniques you use or reference day to day. Covering up to Android 11, this Android Java programming reference guide focuses on non-UI elements with a security focus. You won’t see Android UI development, nor will you see low-level C or kernel techniques. Instead, this book focuses on easily digestible, useful, and interesting techniques in Java and the Android system.

This reference guide was created out of the need for myself to jot down all the useful techniques I commonly reached for, and so I’m now sharing these techniques with you, whether you are an Android internals software engineer or security researcher.
