what is the android exception that best fits this scenario?

PackageManager pm = context.getPackageManager();
List<ResolveInfo> apps = 
    pm.queryIntentActivities(viewDocIntent, PackageManager.MATCH_DEFAULT_ONLY);

if (apps.size() &开发者_Python百科gt; 0)
    context.startActivity(viewDocIntent);
else
    throw new ... SOMETHING

Which exception would you think should be thrown if the resulting list is empty?
