• Limited processor speed
• Limited and slow network access
• Limited or awkward input: soft keyboard, phone
keypad, touch screen, or stylus

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.
