LG Java Platform Overview

It is for “ONE application working seamlessly on all LG mobile devices”.

LG Standard for Unified Java Platform

It standardizes LG Java features to remove fragmentation-related issues.

It makes easy to get the information on the Java features of LG mobile devices.

It provides consistent support for Java ME requirements, JSR requirements,

and JVM behavior across all LG mobile device tiers.
