- 2. Jay Graves - CTO POSSIBLE Mobile @skabber
- 3. Native Apps Are the Best! SO WHY ARE WE TALKING ABOUT HYBRID? • Times Change • Technology moves forward
- 4. 3 Classes of Hybrid App Platoforms • The Wrapper • Any Other Language • Shared Code
- 5. What is not new? BUT STILL AROUND AND GETTING UPDATES • Phone Gap • Ruby Motion • Xamarin
- 6. PhoneGap OR IS IT CORDOVA? • Wrapper App • HTML 5, JavaScript, CSS • iOS, Android, Fire, Blackeberry 10, Firefox OS • Ubuntu, Windows Phone 8, Tizen • Adobe & Apache License
- 7. PhoneGap “I think a big reason why PhoneGap was created is that we wanted to get back to building web apps and using HTML, CSS and JavaScript and not get locked in to a proprietary vendor platform.”
- 8. Ruby Motion • Any Other Language • Ruby (obviously) • iOS, Android, OS X • Can use 3rd party frameworks on both platforms • $16.5 a month, $29 a month, Enterprise
- 9. Ruby Motion HOW DOES IT WORK?
- 10. Xamarin 800LB GORILLA • Any Other Language • C# • iOS, Android, OS X, Windows Phone • 3rd party frameworks must be specially wrapped “components”. • $25 a month, $83 a month or $158 a month, per developer per platform!
- 14. Xamarin.iOS Build Host BUILD ON OS X FROM WINDOWS
- 18. What is new? NKOTB • Silver • Apportable Tengu • Go
- 19. Silver FROM REM OBJECTS • Any Other Language • Swift 1.2 • iOS, Android, Windows • 3rd party frameworks …. ? • Free, $799, $4999
- 20. Silver FIRE IDE
- 21. Silver FIRE IDE

- 27. Go 1.5 RELEASE CANDIDATE • Shared Code / Any Other Language • Go (obviously) • iOS, Android, OS X, Windows, Linux • 3rd Party Frameworks - Yes • Free
- 28. Go 1.5 HOW DOES IT WORK? • Cross compilation • Example: compiling for arm from amd64 • gomobile tool
- 29. gomobile THIS IS WHERE WHERE THE MAGIC HAPPENS go get golang.org/x/mobile/cmd/gomobile Commands: bind build a shared library for android APK and iOS app build compile android APK and iOS app init install android compiler toolchain install compile android APK and install on device version print version
- 30. gomobile BUILD VS. BIND • Your package must have a main function. • Very limited “App” functionality. • OpenGL, Audio, Sprites. • No native UI. • Not very useful at this point. gomobile build -target=[ios | android ]
- 31. gomobile BUILD VS. BIND • Your package must not have a function. • Android outputs an .aar archive. • Wraps Java Native Interface (JNI). • iOS outputs a .framework. • Complete with Obj-C header files. gomobile bind -target=[ios | android ]
