OUR CHOICE: USE JAVA
• Most of our codebase was in Java • J2ME, Classic BlackBerry, Android
• Java is native on Android • 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

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!

MIGRATING FROM ROBOVM
• LibGDX already announced that they are switching to MOE • Their experimental MOE based backend is already available
• RoboVM's features are available on Intel MOE • e.g. RoboVM's Bro can be easily replaced through Nat/J
RoboVM was shut down by Microsoft
