Okhttp will not help here. You need to use ServerSocket.
It is quite simple to build a minimal http server. A small server is hidden in the B4J implementation of Google OAuth: https://www.b4x.com/android/forum/threads/class-b4x-google-oauth2.79426/#content

Two more robust server implementations: [B4X] [class] MJPEG decoder
And: [B4X] FTP Server implemented with Socket and AsyncStreams

my understanding is that you want to post to a server that is expecting soap, yes? if yes, then see erel's post here

I think poster is trying to write a server that runs on android and receives SOAP post requests

B4X:

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("1")
    If FirstTime Then
        server.Initialize(5000, "server")
        Log(server.GetMyWifiIP)
        lblState.Text=server.GetMyWifiIP
        server.Listen
    End If
End Sub

Sub server_NewConnection (Successful As Boolean, NewSocket As Socket)
    If Successful Then
        If ast.IsInitialized Then ast.Close
        ast.Initialize( Me, "ast", NewSocket.InputStream, NewSocket.OutputStream) 'initialize AsyncStreamsText with the socket streams.
    Else
        Log(LastException)
    End If
    server.Listen
End Sub

Sub ast_NewText(Text As String)
    Log("Text: " & Text)
    Log(Text.Length)
   

   
    Dim information As StringBuilder
    information.Initialize
    information.Append("HTTP/1.1 200 OK")
    information.Append("Date: Sat, 18 Apr 2020 13:41:56 GMT")
    information.Append("server: App-webs/")
    information.Append("Connection: close")
    information.Append("Content-Length: 5951")
    information.Append("Content-Type: Application/soap+xml; charset=utf-8")
   
   

   
    If (Text.Contains("Host"))Then
        ast.Write("HTTP/1.1 200 OK "& Chr(10) & Chr(13))
        ast.Write("Date: Sat, 18 Apr 2020 13:41:56 GMT")
        ast.Write("server: App-webs/")
        ast.Write("Connection: close")
        ast.Write("Content-Length: 500")
        ast.Write("Content-Type:"&" text/html;charset=utf-8"&Chr(10) & Chr(13))
       
        ast.Write("<html>helloword<html>"&Chr(10) & Chr(13))
       
        Log("GET INFO")
       
    End If
    End Sub
