| Problem | Reason | Solution | |---------|--------|----------| | | Missing required metadata or wrong API version | Check device's supported VXP spec (often v1.0 only) | | Screen corruption | JAR uses unsupported GUI classes | Replace Canvas with FullCanvas or limit to standard LCDUI | | Conversion tool not found | Most original SDKs are lost | Search archive.org for "VXPlatform SDK" or "LG VXP Tool" | | .jar uses too much memory | VXP runtime has stricter heap limits (e.g., 512KB) | Optimize images, reduce object creation |
