| Feature | Java ME | VXP Runtime | Conversion Feasibility | |---------|---------|-------------|------------------------| | Graphics | LCDUI, Canvas, GameCanvas | Simple framebuffer (no high-level widgets) | Poor – requires full rewrite | | Storage | RMS (Record Store) | Raw file I/O | Moderate – can emulate RMS | | Networking | HTTP, Socket via JSRs | Often missing or proprietary | Very poor | | Sound | ToneGenerator, MMAPI | Basic beep only | Poor | | Threading | Java threads | Real threads (pthread or custom) | Moderate – possible | | App size | Up to 512 KB (typical) | Limited by heap (64–128 KB) | Moderate |
Device Compatibility: .vxp files are specifically for phones with MediaTek chipsets (often running the MRE platform). They will not work on Android or iOS devices.
