<? $mydroid = new Android ();

$ret=$mydroid->dialogSetItems(array("MAC-Adresse","Datum/Zeit","Öffnen","Ende")); $mydroid->dialogShow(); $ret= $mydroid->dialogGetResponse(); print_r($ret);

What is the expected output? What do you see instead?

A List of elements with all above elements. It does not show "Öffnen" - instead I see "null"
