[Moved]how to recognize Java application from Symbian application

[hansorkrutor]

Hi,
in my application, I need a list of all curently running applications. I find them using

wsSession.WindowGroupList

then I make a list with icons and display it.

My problem is, that when I try to finde icon for a Java application my device says "unable to execute file for security reasons". I've found out, that it could do something with capabilities, but I haven't found any capability that would work. So I've decided not to show the icon at all.

So what I need is to decide whether the task (application) is a Symbian app or a Java app and then try to look for the icon or not. Is there any way how to recognize that?

See TSS000465 - Launching MIDlets programmatically on S60 3rd Edition

Carbide.c++ has a Capability Scanner plug-in and emulator's log (%temp%\epocwind.out) will tell you which capabilities were needed at run time.

Thank you for a satisfying answer. I'll not look for the Java icon at the moment and later on, I'll try to find a way how to get AllFilles capability certificate. Is it even possible for me as an amateur developer?

It is the intended usage which matters. Check the guides on http://www.symbiansigned.com

How exactly are you retrieving that icon? There must be a way to get it without AllFiles, or at least so I hope.

I do it like this:

AknsUtils::CreateAppIconLC(skin,closedAppUid,  EAknsAppIconTypeContext,AppIcon,AppIconMsk);
AknIconUtils::SetSize( AppIcon, TSize( 68, 73 ), EAspectRatioPreserved );
AknIconUtils::SetSize( AppIconMsk, TSize( 68, 73 ), EAspectRatioPreserved );
CleanupStack::Pop(2);
iFourthImg->SetSize(size);
iFourthImg->SetPicture(AppIcon,AppIconMsk);

It works perfectly fine with Symbian application icons, but it has capability problem with icons belonging to Java apps. The capability needed is regarding to emulator log the AllFiles one.
