Mobile Devices – The Good • Always with the user • Typically GPS capable • Typically have accelerometer • Many apps are free or low-cost
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
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
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?
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.
