Sharp GX20 Question

Hi, has anyone here had any experience developing for the Sharp GX20?

I've converted a game to the Sharp GX10 which works great, and am now trying
to get it working on the GX20. However, any DeviceControl or MediaPlayer
calls used stop the game working on the GX20 - it displays a "Discontinued"
message. I've tried the game under the emulator I have for GX20 work (I'm
not sure of the version - but the emujava.exe file is dated 22/04/2003) and
it gets as far as a DeviceControl or MediaPlayer call, before throwing up an
ALERT and exiting.

In the case of using the following code:


{
        DeviceControl dc;

        try
        {
                dc = DeviceControl.getDefaultDeviceControl();
                dc.setDeviceActive(DeviceControl.BACK_LIGHT, true);
        } catch (Exception e) { System.out.println("DC error: " + e); }
}


it comes up with the following within the emulator:

ALERT: Class com/vodafone/v10/system/device/DeviceControl is restricted to
access.
kvm_main return code = 123
----- APP jkVmStopped callback begin.
VM callback: appId = 1, event = jkVmStopped
----- APP jkVmStopped callback end.
AMstartMidpApplication return code = -1
finish WINSOCK success.

So even with the try-catch it is being stopped in both the phone and the
emulator. This is the case for vibration and MediaPlayer methods as well.

Does anyone know of a way to use the DeviceControl calls safely?
Alternatively, am I using an old version of the GX20 class librarys (same
date as the emulator - 22/04)?

Cheers,

Ian Manders
