Kuix J2ME to Android

[kamarezzo]

Hi,
I’m trying to port the demo App (Kaprice) of the the Framework Kuix,
wich is a JavaME UI framwork that enables high end application
development ( http://www.kalmeo.org/projects/kaprice). After running
the apk in the emulator, i get the NullPointerException, saying the
the Graphics object of the GameCanvas is null and after loading there
is nothing to see on the Screen (Black screen) . The demo works fine
on the most devices an emulators as J2ME app.
Is there a problem with the GameCanvas on microemulator ? when is the
Graphics object initialized an ready?
Is that a threading problem with Kuix-Task-Worker?

Please help us solving this problem because we are building very
important projects with this framework and we will save a lot of time
if that works gut on Android!

The logcat looks like this:

I'm also having this problem with the MicroEmulator, it appears that the android library is trying to use a J2me graphics object directly;

Here's the Android LogCat output;

Going back to my source file, the offending line (i.e. ChopUpCanvas.java:107) is reproduced below;

displayWidth = g.getClipWidth();

Anybody have any ideas on how to fix this?
