What is Android?
What is Android?What is Android?  An open source Linux-based operating system intended for mobile computing platforms  Includes a Java API for developing applications  It is not a device or product
Why teach Android?
Engaging Students with AndroidEngaging Students with Android  Android has a lot of “buzz” now – Newness – Coolness – Googleness  UI and graphics made simple(r)  Advanced Java skills
What Skills Will Students Learn?What Skills Will Students Learn?  Reinforce the basics: OOP, decomposition, etc.  Separation of UI design and functionality  XML and resource files  Events and Listeners  Callback methods  Threads
Android vs. iPhoneAndroid vs. iPhone  Java vs. Objective-C  Direct install vs. Marketplace vs. App Store  Open source?
What do you need in order to teach Android?
What Should Students Already Know?What Should Students Already Know?  Java! – inheritance, method overriding – interfaces, casting – exceptions – debugging – reading API documentation  Eclipse – easy to pick up quickly, though
Do I Need Phones?Do I Need Phones?  The emulator that is part of the Android toolset for Eclipse is quite good (though a bit slow)  You may be able to get free “developer phones” from Google
