First I had to understand how to use iPhone APIs from Java. Markus Heberlings from the MicroEmulator project helped me a lot in this task. I used Markus's library (straptease) to write a simple backend for MIDPath.
Next I added a directional pad to give a chance to people with large fingers to navigate through complex user interfaces.
Finally, I improved overall performances by compiling native backends for rasterization and SVG rendering.
Currently MIDPath runs on top of JamVM 1.5.1/Classpath and performances are correct for productivity applications. It should be faster when the iPhone backend will use OpenGL ES.
Available features:
- Full support of the MIDP2 widgets (LCDUI)
- JSR226/SVG
- JSR75/File Connection API
- Networking
- Sound
