Editor's Notes
- #6: On November 5, 2007, the Open Handset Alliance, a consortium of technology companies including Google, device manufacturers such as HTC, Motorola and Samsung, wireless carriers such as Sprint and T-Mobile, and chipset makers such as Qualcomm and Texas Instruments, unveiled itself, with a goal to develop

- #8: The Android OS is roughly divided into five sections into four primary layers: Linux kernel — this is the kernel on which Android is based. This layer contains all the low-level device drivers for the various hardware components of an Android device. Libraries — these include all the code that provides the main features of an Android OS. For example, the SQLite library provides database support so that an application can use it for data storage. The WebKit library provides functionalities for web browsing. Android runtime — at the same layer as the libraries, the Android runtime provides a set of core libraries that enable developers to write Android apps using the Java programming language. The Android runtime also includes the Dalvik virtual machine, which allows every Android application to run in its own process, with its own instance of the Dalvik virtual machine (Android applications are compiled into the Dalvik executable). Dalvik is a specialized virtual machine designed specifically for Android and optimized for battery- Application framework — exposes the various capabilities of the Android OS to application developers so that they can make use of them in their applications. Applications — at this top layer, you will find applications that ship with the Android device (such as Phone, Contacts, Browser, etc.), as well as applications that you download and install from the Android Market. Any applications that you write are located at this layer.
