- 6. History of Android •Android Inc. was found in 2003 Oct in Palo Alto, California by ❑ Andy Rubin ❑ Rich Miner ❑ Nick Sears ❑ Chris White • Early, the company were to develop an advanced operating system for Digital Cameras • When companies realized that the market was not large enough, the company diverted its focus towards Mobile Operating System • It was in an intention to be an open competitor for Symbian OS, iPhone OS, Blackberry OS • In July 2005, Google acquired Android Inc. for $50million, and including the Founders(3)Andy Rubin, Rich Miner, Chris White stayed after the acquisition.
- 7. Introduction to Android •Open source software platform and an operating system form mobile devices based on Linux Kernel • Developed by Google and later OHA(Open Handset Alliance) • Allows writing managed code in Java Language • Android has its own virtual machine knows as Dalvik Virtual Machine (DVM) which is used for executing the android app • As of July 2013, Google play-store had over 1million android apps published& 50billion apps downloaded • Now Google Play-store has 2.9 M apps ready to Download • Best-selling OS worldwide on smartphones since 2011 • and on tablets since 2013. • it has over two billion monthly active users

- 14. ANDROID ARCHITECTURE The software stackis split into 4 layers • Applications • Android Framework • Platform Libraries & Android Runtime • Linux Kernel
- 15. • The architectureis based on linux kernel • It helps hardware and software binding for better communication • It is the core layer of android architecture • Platform libraries has its own libraries written in C/C++ and Java based libraries These libraries can be directly accessed using application framework • the Dalvik VM is an interpreter-only virtual machine that executes files in the Dalvik Executable (. dex) format, a format that is optimized for efficient storage and memory- mappable execution. • It is specially designed and optimized for android to ensure that a device can run multiple instances efficiently
- 16. • This isall written in Java, and application framework is the toolkit for all applications • It also provides a generic abstraction for hardware access and manages the user interface and application resources • provides the classes used to create Android applications • Top and final layer where all the applications native and 3rd party Apps will be installed
- 17. INSTALLATION PROCEDURE Required Toolsfor Android Development - Java - Android Studio - Phone or Android Emulator - USB cable

- 21. FUNDAMENTAL COMPONENTS • Activity: Anactivity is a class that represents a single screen • Intent: Intent is used to invoke components. It is mainly used to: ❑ Start the service ❑ Launch an activity ❑ Dial a phone call etc. • Service: Service is a background process that can run for a long time. • Content Provider: Content Providers are used to share data between the applications. • Fragment: Fragments are like parts of activity. An activity can display one or more fragments on the screen at the same time. • AndroidManifest.xml: It contains informations about activities, content providers, permissions etc. • View: A view is the UI element such as button, label, text field etc. Anything that you see is a view.
