Alexander Shitikov: Cross Platform Mobile Development. Business Logic for mobile applications.
0 likes594 views
The document outlines the challenges and solutions for creating a cross-platform mobile business logic library using Java, with a focus on providing a fully-native interface for developers. Key features discussed include memory management, threading, and method overloading, alongside examples illustrating Java-to-native object interactions. It concludes with project status and contact information for further inquiries.
![INHERITANCE AND MAPPING
• class -> @interface
• interface -> @protocol
• boolean -> bool
• byte -> char
• …
• Int[] -> PrimitiveIntArray
• Int[][] -> NSArray<PrimitiveIntArray>
• Object -> MTCObject](https://image.slidesharecdn.com/miedzyplatformowymobiledevelopmentlogikabiznesudlaaplikacjimobilnych-160223125400/85/Alexander-Shitikov-Cross-Platform-Mobile-Development-Business-Logic-for-mobile-applications-17-320.jpg)
