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. You will: Discover the differences between and how to access application names, package names, IDs, and unique identifiers in Android Quickly reference common techniques such as storage, the activity lifecycle, and permissions Debug using the Android shell Work with Android's obfuscation and encryption capabilities Extract and decompile Android applications Carry out Android reflection and dex class loading.

There are more than one billion Android devices in use today, each one a potential target. Unfortunately, many fundamental Android security features have been little more than a black box to all but the most elite security professionals—until now. In Android Security Internals, top Android security expert Nikolay Elenkov takes us under the hood of the Android security sys­tem. Elenkov describes Android security archi­tecture from the bottom up, delving into the imple­mentation of major security-related components and subsystems, like Binder IPC, permissions, cryptographic providers, and device administration. You’ll learn: –How Android permissions are declared, used, and enforced –How Android manages application packages and employs code signing to verify their authenticity –How Android implements the Java Cryptography Architecture (JCA) and Java Secure Socket Extension (JSSE) frameworks –About Android’s credential storage system and APIs, which let applications store cryptographic keys securely –About the online account management framework and how Google accounts integrate with Android –About the implementation of verified boot, disk encryption, lockscreen, and other device security features –How Android’s bootloader and recovery OS are used to perform full system updates, and how to obtain root access With its unprecedented level of depth and detail, Android Security Internals is a must-have for any security-minded Android developer.

The Complete Guide to Customizing Android for New IoT and Embedded Devices Inside the Android OS is a comprehensive guide and reference for technical professionals who want to customize and integrate Android into embedded devices, and construct or maintain successful Android-based products. Replete with code examples, it encourages you to create your own working code as you read--whether for personal insight or a professional project in the fast-growing marketplace for smart IoT devices. Expert Android developers G. Blake Meike and Larry Schiefer respond to the real-world needs of embedded and IoT developers moving to Android. After presenting an accessible introduction to the Android environment, they guide you through boot, subsystem startup, hardware interfaces, and application support--offering essential knowledge without ever becoming obscure or overly specialized. Reflecting Android's continuing evolution, Meike and Schiefer help you take advantage of relevant innovations, from the ART application runtime environment to Project Treble. Throughout, a book-length project covers all you need to start implementing your own custom Android devices, one step at a time. You will: Assess advantages and tradeoffs using Android in smart IoT devices Master practical processes for customizing Android Set up a build platform, download the AOSP source, and build an Android image Explore Android's components, architecture, source code, and development tools Understand essential kernel modules that are unique to Android Use Android's extensive security infrastructure to protect devices and users Walk through Android boot, from power-on through system initialization Explore subsystem startup, and use Zygote containers to control application processes Interface with hardware through Android's Hardware Abstraction Layer (HAL) Provide access to Java programs via Java Native Interface (JNI) Gain new flexibility by using binderized HAL (Project Treble) Implement native C/C++ or Java client apps without bundling vendor libraries

Learn how to pen-test, reverse engineer, and review iOS and Android devices and applications; dive deep into evaluating mobile apps and operating systems, and better defend your organization against the onslaught of mobile device attacks.
