Subject: Re: Sharp GX20 Question

Putting:

MIDxlet-API: VSCL-1.0.1

will fail the vodafone QA criteria. (I presume this is for Vodafone...)
The value for the GX20 should be:

MIDxlet-API: VSCL-1.1.0
Also you have to enter
MIDxlet-Network: Y
or
MIDxlet-Network: N
(depending on if your MIDlet needs network access)


I keep seeing questions on this list about Jar/Manifest fields needed
for different handsets/operators, It would be a good idea if we could
collate all the answers into a FAQ. I'm willing to help put one together if
people send me the info...

you need to specity both these paramters in the jad:

MIDxlet-API: VSCL-1.0.1
Midlet-Install-Notify: http://a.valid.url.for.gx20.security-model

both must be present else if fails

you can also change the scale factor of the gx20 (which by default scales to
120x130):
MIDxlet-Application-Resolution: w,h

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
