INTRODUCTION o Mobile operating system is a software platform on which application programs can run on mobile devices. o Different types of mobile operating system. o The given diagram describes the interaction between the user (mobile user),application (internet ,camera etc),operating system(mobile OS) & hardware(mobile phone). 1. Android OS 2. iPhone OS 3. Windows mobile 4. Palm 5. Symbian OS etc. 4. Android Mobile OS: Revolution in mobile experience Android was founded in Palo Alto ,California ,in October 2003 by Andy Rubin ,Rich Miner ,Nick Sears and Chris White . Android is an open system supported by Open Handset Alliance. Open System refers to software/operating system whose source code is available for understanding and possible modification and improvement. Android software stack and framework is built on Linux kernel and programmed in C / C++ / Java and XML. Its minimum requirement is 200MHZ processor, 32 MB RAM,32 MB storage. Android specially developed for java based applications. It supports more than 4lakh apps. 5. Open handset alliance(OHA) The Open Handset Alliance (OHA) is a business alliance of 78 firms Which are allowed to use source code of Android and develop open standards for mobile devices. Major group members of OHA group is Google , HTC, Sony, Dell , Intel, Samsung, Nvidia , motorola , LG and many more. 6. Architecture & Framework 7. o Linux version 2.6.x for core system services. o Provides proven driver model to build the software stack from scratch or customize it from the available software. o Provides memory management ,process management ,security model, networking and lot of core OS infrastructure. o Android using Java over Linux is a smart move. Both Java and Linux are proven technology, and provide portability for mobile application on Android platform. 8. Libc: C standard Library SSL: Secure socket layer Surface manager: Responsible for composing different drawing surfaces onto the screen. Open GL|ES: 3D image engine SGL:2D image engine Hence we can combine 3D & 2D graphics application. Media Framework: Core part of the android multimedia (MPEG4,H264,MP3,AAC) Free type: to render the fonts. Webkit: open source browser engine . Helps to work well on small screen. SQLite : Embedded database. 9. Android runtime meets the needs of running in an embedded environment i.e. where is limited battery ,limited memory & limited CPU. CORE LIBRARIES: Java programming language Contains all the collection class,ulities,IO .. All these utilities which we come across & expected to use. DALVIK VIRTUAL MACHINE: Java based license free VM Optimization for low memory requirements. DVM runs .dex files (byte code) that converts during built time. More efficient & run very well on small processors. Structure are designed to be shared across processes due to which multiple instance of DVM running on devices at the same time one in several processes. 10. FUNCTIONS: 1. Activity UI component typically corresponding to one screen 2. Intent Receiver Responds to notification or status changes.Can wake up your process. 3. Service Performs tasks that runs in a background. 4. Content provider Enable applications to share data. 11. The top of the Android software stack are the applications. 1. Native applications 2. Third party applications 12. Feature of android operating system: o Open platform o Has Centralized notification system o Ease to use o Network connectivity o Multitasking o Security & privacy. o Memory management o Power management 13.

Developing app in android The Android SDK provides you the API libraries and developer tools necessary to build, test, and debug apps for Android. Android Software Development Kit (Android SDK): Developer : Google Written in : Java Operating System : Cross platform Available in : English Type : IDE,SDK o If you're a new Android developer, we recommend you download the ADT Bundle to quickly start developing apps. It includes the essential Android SDK components and a version of the Eclipse IDE with built-in ADT (Android Developer Tools) to streamline your Android app development. 19. Fact and figure: 20. Android vs iPhone We can set any app as a default on android Android just drag and drop for syncing by using USB cable on computer Google charges for android developers only $5 Android OS have Flash support It is impossible on iPhone.Have to click manually iPhone syncing only with iTunes Apple charges for app developers $100 While the iPhone only has html5 support 21. LIMITATIONS: Hangs a lot Drain battery Internet connection is important Over heats 22. Future scope & conclusion: Future of android is beyond imagination. It has opened a new stream of technological advancements. Indias first android based MICRO OVEN Worlds first android car ROEWE 350 23. ANDROID POWERED CAMERA 24. ANDROID POWERED WASHING MACHINE Worlds First HDTV that runs on the Android operating system 25. A DESKTOP HOME or OFFICE PHONE running android ANDROID POWERED WATCH 26.
