- 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 11
- 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 12
- 13. Applications 13
- 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 14
- 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. 15
- 16. Life Cycle of an Android Application 16
- 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. 17
