Cross-Platform Native Apps in Java (budapest.mobile)
0 likes447 views
This document discusses developing cross-platform native apps using Java with the Intel Multi-OS Engine (MOE). It describes MOE's capabilities like using Java to build iOS apps, its performance compared to other solutions, and how its bindings generator allows full access to native APIs. MOE allows building once and deploying to multiple platforms like iOS and Android without rewriting code.
