10.  Linux Version 2.6
 Security, Memory & Process Management
 Hardware Abstraction Layer
 Efficient computing resource management
 Stable and proven OS for mobile platform 10

11. Android Runtime
 Includes a set of core libraries that provides most of
the functionality-JAVA
 Optimized for low memory requirements
 Every Android application runs in its own process
 Dalvik VM executes files in the (.dex) format
 Device can run multiple VMs efficiently

12.  Parts of this toolkit are provided by Google, and
parts are extensions or services that you write.
 Manages the life cycle of applications and a
common “back-stack” for user navigation

14. Development Tools
The Android SDK includes a variety of custom tools that help you develop
mobile applications on the Android platform.Three of the most significant
tools are:
1.Android Emulator -A virtual mobile device that runs on our
computer -use to design, debug, and test our applications in an actual
Android run-time environment
2.Android Development Tools Plugin -for the Eclipse IDE - adds
powerful extensions to the Eclipse integrated environment
3.Dalvik Debug Monitor Service (DDMS) -Integrated with Dalvik -this
tool let us manage processes on an emulator and assists in debugging

15. Anatomy of an Android Application
There are four building blocks for an Android application:
Activity
-a single screen
Service
-code that is long-lived and runs without a UI.
Content Provider
- manages a shared set of application data
 Broadcast Receiver
-receive and respond to any broadcast announcements.

17. Android Building Blocks
These are the most important parts of the Android APIs:
AndroidManifest.xml
-the control file-tells the system what to do with the top-level components
Android Layout xml
- The files for design different layouts and UI.
