SOAP issue in Appcelerator Titanium (using suds.js) - not working with Android

we are programming a small “home device” application as part of our study using Appcelerator Titanium. We programmed the interface in Java, which is connected to our front-end applications with an interface that can receive requests through a SOAP call. Therefore, we used suds.js. Everything works fine with iOS, but nothing happens on Android, and we don’t know why. :-( First of all, we want to give the user authorization to authorize the user. The username and password will be sent to the server server, which will subsequently provide the user token. Everything works fine in iOS, Android seems to have a problem with the following code, which I noticed with various test comments, because comments in this code do not appear in the developer console:

suds.invoke('login', callparams, function(xmlDoc) {
        Titanium.API.info("Test after function is called");

            var results = xmlDoc.documentElement.getElementsByTagName('return');
Titanium.API.info("another test comment");
            Titanium.API.info(results);

            if (results && results.length>0) {
                var isAdmin = results.item(0).getElementsByTagName('admin');
                if(isAdmin.item(0).text == "true") {
                    Titanium.API.info("isAdmin: true");
                    Titanium.App.Properties.setBool('isAdmin', true);
                } else {
                    Titanium.API.info("isAdmin: false");
                    Titanium.App.Properties.setBool('isAdmin', false);
                }

                var userToken = results.item(0).getElementsByTagName('userToken');
                Titanium.API.info("userToken: " + userToken.item(0).text);
                Titanium.App.Properties.setString('userToken', userToken.item(0).text); 
                Titanium.App.Properties.setString('username', username.value);

                //Rein oder raus???
                //alert("Login erfolgreich! \n isAdmin: " + isAdmin.item(0).text + " \n userToken: " + userToken.item(0).text)

                //Aufruf Hauptmenüfenster
                openWindow('js/menue.js', 'Hauptmenü', true);

                } else {
                    var resultsError = xmlDoc.documentElement.getElementsByTagName('S:Fault');
                    var errorString = resultsError.item(0).getElementsByTagName('faultstring');
                    Titanium.API.info("error: " + errorString.item(0).text);
                    alert(errorString.item(0).text);
                }
        });
