What’s New in Hybrid App Development

Jay Graves - CTO POSSIBLE Mobile@skabber

Native Apps Are the Best!SO WHY ARE WE TALKING ABOUT HYBRID?

• Times Change • Technology moves forward

3 Classes of Hybrid App Platoforms

• The Wrapper • Any Other Language • Shared Code

What is not new?BUT STILL AROUND AND GETTING UPDATES

• Phone Gap

• Ruby Motion

• Xamarin

PhoneGapOR IS IT CORDOVA?

• Wrapper App

• HTML 5, JavaScript, CSS

• iOS, Android, Fire, Blackeberry 10, Firefox OS

• Ubuntu, Windows Phone 8, Tizen

• Adobe & Apache License

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.”

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

Ruby MotionHOW DOES IT WORK?

Xamarin800LB 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!

• Any Other Language / Shared Code

• Swift, Obj-C, Java - Android only

• iOS, Android

• 3rd Party Frameworks …?

Apportable TenguHOW DOES IT WORK?

Go

Go1.5 RELEASE CANDIDATE

• Shared Code / Any Other Language

• Go (obviously)

• iOS, Android, OS X, Windows, Linux

• 3rd Party Frameworks - Yes

• Free

Go 1.5HOW DOES IT WORK?

• Cross compilation

• Example: compiling for arm from amd64

• gomobile tool

gomobileTHIS 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

gomobileBUILD 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 ]

gomobileBUILD 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 ]

GoDOWNSIDES

• Very early days.

• Only a subset of Go types are supported.

• int, float, string, bool

• functions, interfaces, structs

• Work in progress

• Debugging.

• Tooling

• Bitcode? •
