An in-depth exploration of the inner-workings of Android: In Volume I, we take the perspective of the Power User as we delve into the foundations of Android, filesystems, partitions, boot process, native daemons and services.

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 fascinating inside story of how the Android operating system came to be. In 2004, Android was two people who wanted to build camera software but couldn't get investors interested. Today, Android is a large team at Google, delivering an operating system (including camera software) to over 3 billion devices worldwide. This is the inside story, told by the people who made it happen. Androids: The Team that Built the Android Operating System is a first-hand chronological account of how the startup began, how the team came together, and how they all built an operating system from the kernel level to its applications and everything in between. It describes the tenuous beginnings of this ambitious project as a tiny startup, then as a small acquisition by Google that took on an industry with strong, entrenched competition. Author Chet Haase joined the Android team at Google in May 2010 and later recorded conversations with team members to preserve the early days of Android's history leading to the launch of 1.0. This engaging and accessible book captures the developers' stories in their own voices to answer the question: How did Android succeed?
