Have you tried adding a zoom element with an integer from 1 to 23 in there? Like this

uepd.append("zoom", "10");

I'm trying to use this snippet as well and I'm getting this error:

unreported exception net.rim.device.api.system.ApplicationManagerExcept ion; must be caught or declared to be thrown
ApplicationManager.getApplicationManager().runAppl ication(ad2, true);

Am I missing something here? I copied everything exactly how it was in the beginning of the thread.

EDIT: I just wrapped it in a try catch block and that error went away. Weird.
