THE MOBILE CHALLENGEDeploy the same app on multiple platforms

Rewrite from Scratch Go Cross-Platform


OUR CHOICE: USE JAVA

• Most of our codebase was in Java • J2ME, Classic BlackBerry, Android

• Java is native on Android • We don't like reinventing the wheel...

• ... and debugging it all over again • Native UI

• Customers did not like Cross-Platform UIs • Great development tools

• Debugger, IDEs, Native API access, UI Designer

And design apps The Right WayTM

MULTI-OS ENGINE

• Use any language • JVM, C / C++, ObjC, Swift

• Your favorite tools • AS / IDEA, Eclipse, Xcode • Gradle, Maven builds • JUnit • CI servers (e.g. Jenkins)

• Debug native and Java code at the same time

MOE is Flexible

Application Code (Java, Objective-C, Swift, C / C++)


NAT/J - JAVA TO NATIVE BINDING

• Java to native bindings defined using Java annotations • C and Objective-C runtimes supported • Manages Objective-C object lifecycle • Dynamically links Java and native functions

• Automatic binding generator • The full iOS API is automatically generated • Bind Objective-C ViewController stubs to Java • Generate bindings for 3rd party Objective-C and Swift libraries

• Works on any JNI compatible Java VM (Oracle, ART ...)

Never use JNI Again!

ADVANCED JAVA & NATIVE INTEGRATION

• Use any JVM language (Scala, Kotlin, Clojure ... etc.)

• Use Java libraries from Objective-C / Swift • Implement Objective-C protocols in Java • Extend Objective-C classes in Java

• Build your UI in Java, Swift or Objective-C • Automatically generate bindings with Nat/J

Use the tools best suited for the task
