- 8. Mobile Devices – The Good • Always with the user • Typically GPS capable • Typically have accelerometer • Many apps are free or low-cost
- 9. Mobile Devices – The Not-So-Good • Limited screen size and colors • Limited battery life • Limited processor speed • Limited and slow network access • Limited or awkward input: soft keyboard, phone keypad, touch screen, or stylus • Limited web browser functionality • Often inconsistent platforms across devices • Warning: Blackberry thumb
- 10. Mobile Applications • What are they? – Any application that runs on a mobile device • Types – Web apps: run in a web browser • HTML, JavaScript, Flash, server-side components, etc. – Native: compiled binaries for the device
- 11. Native App Development Environments • Java ME • .NET Compact Framework (C++, C#, VB.NET) for Windows Mobile • Qualcomm’s BREW (C or C++) • Symbian (C++) • BlackBerry (Java) • Android (Java) • iPhone (Objective-C) • Is having so many choices a good thing?
- 12. Development Environments • Most platforms have an SDK that you can download and build against • Every platform has an emulator that you can use to test your apps • Most emulators are configurable to match a variety of mobile devices – Various screen sizes, memory limitations, etc.

- #8: Worldwide, Nokia still leads smartphone sales with 44.3% of the market, but that represents a significant slide over the last few years. As recently as 2006, Nokia's Symbian platform accounted for over 72% of smartphones sold; now it represents just 50.3%. Nokia has particularly lost ground among business users due to the popularity of RIM's BlackBerry, which now claims a 20.9% share of smartphones. Nokia recently announced a "partnership" with Microsoft, which largely just involves porting Pocket Office apps to Symbian in a bid to make Nokia's devices more competitive with the BlackBerry. In October, 2009, Gartner Inc. predicted that by 2012, Android would become the world's second most popular smartphone platform, behind only the Symbian OS which powers Nokia phones very popular outside the US. Meanwhile, BlackBerry would fall from 2nd to 5th place, iPhone would remain in 3rd place, and Microsoft's Windows Mobile would remain in 4th place.
