  • 2. Introduction to LG Java Platform What is LG Java Platform? © 2010 LG Electronics Inc. LG Mobile Developer Network
  • 3. Background Issued from some operators and developers: - “One application for all devices. Not fragmented way” - “Implementation differences due to JSR vagueness or ambiguity” APP1 Device 1 APP2 Device 2 APP3 Device 3 Diversity in supported Java features, JSRs, and Developers JVM behavior APPn Device n © 2010 LG Electronics Inc.

  • 4. LG Java Platform Overview LG Standard for Unified Java Platform It is for “ONE application working seamlessly on all LG mobile devices”. 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. © 2010 LG Electronics Inc. LG Mobile Developer Network
