I packaged an app I know works and I get this error...works fine normally.
Error using getappdata
Value must be a handle.
Error in AftModV2App/attachOncleanupToFigure (line 109)
appdata = getappdata(fig);
Error in AftModV2App/startApp (line 94)
obj.attachOncleanupToFigure(appdesigner.internal.service.AppManagementService.getFigure(obj.AppHandle));
Error in AftModV2App (line 48)
startApp(obj)
Error in appinstall.internal.runapp>execute (line 116)
out = evalin('caller', [script ';']);
Error in appinstall.internal.runapp>runapp13a (line 95)
outobj = execute(fullfile(appinstalldir, [wrapperfile 'App.m']));
Error in appinstall.internal.runapp>preamble18b (line 60)
appobj = runapp13a(appinstalldir);
Error in appinstall.internal.runapp (line 13)
out = preamble18b(appinstalldir);
Error in matlab.apputil.run (line 45)

Impossible to say much with only that information other than that when something works within Matlab, but not in a compiled app it is, more often than not, because you have forgotten to include a (or multiple) file in the app.

This line:-
appdesigner.internal.service.AppManagementService.getFigure(obj.AppHandle)
returns a null value here in code:-
if(ishandle(obj.AppHandle))
% Traditional graphics handle based app
obj.attachOncleanupToFigure(obj.AppHandle);
elseif isa(obj.AppHandle, 'matlab.apps.AppBase')
% appdesigner based app
obj.attachOncleanupToFigure(appdesigner.internal.service.AppManagementService.getFigure(obj.AppHandle));
elseif isa(obj.AppHandle,'handle') && ~isvalid(obj.AppHandle)
% Cleanup in the case where the handle was invalidated before here
appinstall.internal.stopapp([],[],obj)
else
% There will be no call to stopapp, instead decrease the refcount
% now to prevent future clearing issues
AftModV2App.refcount(obj.Increment);
munlock;
end
obj.AppHandle is not empty.
