  1. vs. Ease of Developing 3rd Party Applications

  2. Points of Interest • Closed Source vs. Open Source • Does It Matter? • Objective-C vs. Java • Implementation • SDKs, Software Development Kits • App Stores • Conclusion

  3. Closed Source vs. Open Source • Closed Source • Trade Secret • Source code is not made available to the public • Your purchase a license to use the software • Limited platform availability • Vendor Lock-In

  4. Closed Source vs. Open Source • Open Source • Source code is freely available • Typically runs on a variety of platforms • No Vendor Lock-In • Variety of licenses available

  5. Closed Source vs. Open Source • Does It Matter? • Redistribution • Hardware Environment • Robust APIs • Cost of Entry • Development License • Platform Support

  6. Objective-C vs. Java • Objective-C • Superset of C • C + Smalltalk • Smalltalk Objects • “Pure” Object-Oriented Language

  7. Objective-C vs. Java • Java • Inspired by C++ • Not “Pure” • Portability • Java Virtual Machine • Speed

  8. Objective-C vs. Java • Implementations • Objective-C • Garbage Collection • Cocoa/Cocoa Touch • Java • Partial Implementation on Android • Dalvik Virtual Machine • Cross-platform Compatibility

  9. SDKs, Software Development Kits • iPhone SDK • Requires Mac OS X • Requires Intel-based machine • Uses Xcode IDE • Free to Download • Same developer tools as Mac OS X SDK

  10. SDKs, Software Development Kits • Android • Uses Eclipse IDE • Windows, Linux, and OS X • Open Source • Requires Java SDK and Android Development Tools plug-in

  11. App Stores • iPhone • Application Approval Process • Application Ratings • Annual Fee • Mac OS X and iPhone OS

  12. App Stores • Android • No Approval Process • Developing and Selling Applications • One-Time Fee • Available to all Android devices
