Android Question Response.GetString("UTF8") problem

oh, god... either i'm too old for this or i'm too dumb
but i am missing something here

i created a sub for testing
it sends username and password to my webservice and gets back a ReturnCode
very basic and simple
but i can't make it work

can anyone please point me to the right way ?
many thanks



Sub btnTmpZeev_Click
ZeevUtils.Beep

Dim j As HttpJob
j.Initialize("", Me) 'name is empty as it is no longer needed

Dim sXML As String
Dim s As String=""

sXML = _
"<?xml version='1.0' encoding='utf-8'?>" & _
"<soap12:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap12='http://www.w3.org/2003/05/soap-envelope'>" & _
"<soap12:Body>" & _
"<GetCode xmlns='https://mywebsite.com/'>" & _
"<username>"&UserName&"</username>" & _
"<Password>"&Password&"</Password>" & _
"<ReturnCode/>" & _
"</GetCode>" & _
"</soap12:Body>" & _
"</soap12:Envelope>"

'j.PostBytes(URL,sXML)
j.PostBytes(URL,sXML.GetBytes("UTF8"))

Wait For (j) JobDone(j As HttpJob)
If j.Success Then
'The result is a json string. We parse it and log the fields.
Dim jp As JSONParser
jp.Initialize(j.GetString)
Dim RetValXml As List = jp.NextArray
For Each Line As Map In RetValXml
s = "ReturnCode: " & quot.Get("ReturnCode")
Next
Else
s = "Error-"& j.ErrorMessage

End If

j.Release

End Sub

oh, once again i did it the wrong way...
how do i use the code /code tags ?

anything i try i get error: The server cannot service the request because the media type is unsupported.

1. Please use [code]code here...[/code] tags when posting code.

2. I guess that you need to set the content type.
Example of setting the content type: https://www.b4x.com/android/forum/threads/httputils2-content-type.76264/#post-483841 (you need to set it to a different type).

THANK YOU!!
this did work
once again i saved


now i get success
but how to i get the returning XML with the answer ?
there is a returning value i need to get from there - "ReturnCode"

thank you all guys, my app is now working
managed to parse the xml with my old code
