This document discusses mobile and tablet operating systems and development. It covers the key mobile OSes including iOS, Android, Blackberry and Windows Phone 7. It discusses native app development versus web apps and why native apps are more popular. It also covers the shift to tablets, the major players in the tablet market, and considerations for developing for tablets.

2. About Me Mobile Development Tablet Development Overview of today

3. About Me

4. Anything less than 7 inches in screen size Phones PDAs Ipods Ipod Touch GPS devices What is mobile?

5. Key mobile OSes: Symbian OS BlackBerry OS Google Android Apple iOS Windows Phone 7 (formerly Windows Mobile) Others include: HP Palm webOS Samsung bada Mobile Handset OSes Globally

6. Mobile Handsets in US

7. Windows Phone 7 (ARM only) Proprietary (Microsoft) No multitasking Programming: Silverlight/XNA, C#.NET/VB.NET Android (ARM, x86, …) Open-source Multitasking Programming: Java (Apache Harmony), scripts Other OS features Most require app code signing Many support Adobe Flash/AIR, multitasking ARM is predominant ISA Symbian (^ n ) OS (ARM only) Open-source (Nokia) Multitasking Programming: C++, Java ME, Python, Qt/HTML5 SWITCHING TO WINDOWS 7! BlackBerry OS (ARM) Proprietary (RIM) Multitasking Many enterprise features Programming: Java ME, Adobe AIR (tablet) iPhone OS (ARM only) Proprietary (Apple) Multitasking Multi-touch interface Programming: Objective-C Mobile Handset OSes

8. Originally developed for the iPhone, it has since been extended to support other Apple devices such as the iPod touch, iPad and Apple TV. Apple's App Store contains more than 300,000 iOS applications iOS 4.3 was released to the public on March 9, 2011, 2 days before the iPad 2. In addition to earlier features, the public release of iOS 4.3 includes many new features such as a Nitro JavaScript engine in Safari, making Safari run up to twice as fast. iOS IOS

9. Fastest growing mobile OS Over 300,000 Android activations a day Android overtook iOS as the dominant OS in US during 2H 2010 First phone launched HTC G1 in 2008 Currently an OS of choice for Motorola, HTC, Samsung, Sony Ericsson, among others Software updates every few months Android OS ANDROID

10. Native vs Web Apps

11. “ Native” Apps: Written in a programming language for a targeted operating system Apple iOS Devices: iOS SDK, using Objective-C Android Devices: Android SDK, using Java Have access to all features of the hardware Camera, GPS, Accelerometer, Microphone, etc. Are distributed via the respective app “marketplace” iTunes App Store, Android Marketplace iOS apps are subjected to rigorous testing/acceptance process; Android apps are submitted to the Marketplace with little oversight Development fees: Apple: SDK is free (registration required), $99 to submit apps to App Store Android: SDK is free, $25 to submit apps to Android Marketplace Native vs Web Apps

12. “ Web” Apps: Web-based applications written with traditional web programming languages HTML/CSS, Javascript, PHP/.NET/JSP Have limited access to device hardware (depends on platform) Can be used cross-platform (some restrictions apply) Most are intended to be used when the device is online; some have capabilities for offline use Most platforms have some semblance of a “web app store,” but the stores and their contents vary widely No centralized marketplace for all platforms Native Vs. Web Apps

13. $$$ (or the potential for $$$) iOS App Store provides a “filter” for apps, so users have at least one means of gauging their worth All app marketplaces provide ratings, comments, rankings Interacting with the hardware provides significant app potential Users have been “trained” to search the markets first Native Apps: Why so Popular? NATIVE

14. Can produce vivid, dynamic websites with high levels of interaction Can integrate web services (no need for local data sources) HTML5 affords video, audio input CSS3 includes animation, some 3D rendering No need for Flash (!!!!!!) Browser support varies widely Most data-driven features require the app to be used “online” Web Apps: Html 5 + CSS3 + Javascript DEVELOPMENT

15. Free with Apple SDK registration Provides means to create Mac “widgets” and Safari/Mobile Safari web apps Gives developers a nice IDE for web app development Includes images and usage guidelines to create a native iOS-looking web app Produces web apps that look like iOS apps on any other mobile browser Xcode DEVELOPMENT

16. Eclipse IDE for Android

17. Xcode interface

18. Shift to Tablets

19. iOS and Android Are biggest players Windows Tablet still a possibility Tablet Market Share by Manufacturer

20. Tablet Market Share by OS Note: QNX = Blackberry

21. Re-use of code across platforms from mobile Different form factor size an issue 1GHz dual-core Apple A5 custom-designed, high-performance, low-power system-on-a-chip 2 cameras 9.7-inch (diagonal) LED-backlit glossy widescreen Multi-Touch display with IPS technology Three-axis gyro Accelerometer Ambient light sensor iPad

22. 10.1-inch capacitive screen a 5MP HD camcorder 1 Ghz dual core Tegra 2 Barometer, accelerometer, gyroscope Motorola Xoom (Android 2 nd Gen. Example)

23. Blackberry?

24. “ Apparently Apple has agreed to a price three to four times higher than normal in exchange for reserving a large portion of the highest quality screens the manufacturer.” Apple’s Lead in the Tablet Market Apple’s network of retail stores , with knowledgeable employees and the periodic hysteria-inducing product, you can interact with the iPad inside the friendly confines of an Apple Store cannot be matched by competitors at the Staples, Walmarts and Best Buys of the world. • Apple has put together a decent moat on pricing , so much so that Asus declared no intention of jumping into the tablet market. • Also, integration of software. The presence of dozens of killer apps, downloadable immediately – or in many cases, already in the possession of the owners of iPhone or Touch devices

25. Windows Tablet Interfaces…. Still a possibility – remember the Symbian OS? Was first to market, in early 2000s

26. Still can use Eclipse and Xcode (or Visual Studio for Windows) However, 7 or 10 inch form factor? Still debatable Applications for data entry (POS, Medical) Next gaming platform? Replacement for netbooks/laptops? Developing for Tablet

27. Mobile apps/platforms are still changing, even as they mature Tablets are still in a state of flux Possible code-reuse, however form factors aren’t the same Shift from laptops to tablets? In conclusion
