Hi,

I'm trying to add a MenuItem to my project:

protected void makeMenu (Menu menu, int instance ) {

super.makeMenu(menu, instance);

menu.add (new MyMenuItem());

}

class MyMenuItem extends MenuItem {

MyMenuItem() {

super(new StringProvider("Menu item text"), 100000, 0);

}

}

but when I click the Menu Button I receive NoClassDefFound


    Thanks,

Have you stepped through your code to see what is causing the problem?

Are you running on a suitable level of simulator given the OS level you have compiled with?

I'm looking for a MenuItem which is suitable for OS 5.0 and above....

5.0.0 does not have the MenuItem constructor that takes a StringProvider. That was only introduced in 6.0.0. Which means you are probably compiling for 6.0.0 and running on 5.0.0, which you shouldn't do.

Thank you for your reply,

Fix me if I'm wrong:

If I want my app to be compatible with both OS 5.0 & 6.0 I need to check the OS version,

If 5.0

Create a MenuItem with the constructor of OS 5.0 - http://www.blackberry.com/developers/docs/5.0.0api/net/rim/device/api/ui/MenuItem.html

if 6.0

Create a MenuItem with the constructor of OS 6.0 - http://www.blackberry.com/developers/docs/6.0.0api/net/rim/device/api/ui/MenuItem.html

???

yes you can't pass stringprovider in menuItem constructor's if you use os5.0 you can surely use it for 6.0 and above it.....
