Android Security Overview

The Android project has published an Android Security
that provides information about Android security at the system
and kernel level as well as application security and more. "This document outlines the goals of the Android security program, describes the fundamentals of the Android security architecture, and answers the most pertinent questions for system architects and security analysts. This document focuses on the security features of Android's core platform and does not discuss security issues that are unique to specific applications, such as those related to the browser or SMS application. Recommended best practices for building Android devices, deploying Android devices, or developing applications for Android are not the goal of this document and are provided elsewhere."
