Presentation Transcript

  1. CS569 Selected Topics in Software EngineeringSpring 2012 Mobile overview +Introduction to Titanium

  2. Start installationin parallel with this presentation • Windows + Linux users • Install Oracle JDK, set PATH and JAVA_HOME • Install Firefox • Install Appcelerator’s Titanium Studio • Install Android SDK • Mac users • Install Xcode • Install Appcelerator’s Titanium Studio • Optional: Install Android SDK

  3. Differences between one platform and another and another and another and another and another and… • Physical differences • Screen size • Textual input • Scrolling • Stylistic differences • “Back” and “Cancel” buttons • Placement of navigation bar • Colors

  4. Survey of over 2000 developers (2010 Q4 Mobile Developer Report)

  5. Android rising

  6. Android jobs rising

  7. Lessons from the market • Platforms come and go from fashion • iOS -> Android right now • What is next? • Gotta keep your code from going stale • Gotta keep your skills from going stale

  8. Option 1: Write platform-independent code, interpose libraries Your code This is basically how JavaScript worksin web browsers (each browser implements the ECMA specification for JavaScript and implements specified objects with binary libraries) Platform-specific binary libraries Some random platform

  9. Option 2: Write platform-independent code, compile to platform Your code This is basically how C++ works (a compiler for each platform compiles the source code into an .exe or whatever binary format is accepted by the target operating system and hardware) Compiler Platform-specific binary Small runtime library Some random platform

  10. Platform-independent frameworks • Option 1: just libraries, no compiler • jQTouch – pure HTML+CSS+JS • PhoneGap – HTML+CSS+JS + binary libraries

  11. Platform-independent frameworks • Option 2: compiler • Appcelerator – write JS, compile to binary • Adobe Air – write ActionScript, compile to Flash • In practice, both of these require platform-specific runtime libraries, even though they theoretically could compile code to pure binaries that would not require any runtime library.

  12. Platform-specific frameworks • (Mostly) platform-specific frameworks • XCode – compiles Objective C to iOS binaries • Android SDK – compiles Java to Android binaries

  13. Pros and cons

  14. Titanium Appcelerator “Hello World” Walkthrough
