Answer 1

So, it does not matter which ever tag you have example : v:Envelope or soapenv:Envelope. The soapserver will automatically parse it. Also, to add prefix in xml envelop you need to extend class SoapSerializationEnvelope.

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.xmlpull.v1.XmlSerializer;

import java.io.IOException;

public class CustomSoapSerializationEnvelope extends SoapSerializationEnvelope {

    CustomSoapSerializationEnvelope(int version){
        super(version);
    }

    @Override
    public void write(XmlSerializer writer) throws IOException {
        writer.setPrefix("i", xsi);
        writer.setPrefix("d", xsd);
        writer.setPrefix("c", enc);
        writer.setPrefix("v", env);
        writer.setPrefix("db","http://db.hott.com");
        writer.startTag(env, "Envelope");
        writer.startTag(env, "Header");
        writeHeader(writer);
        writer.endTag(env, "Header");
        writer.startTag(env, "Body");
        writeBody(writer);
        writer.endTag(env, "Body");
        writer.endTag(env, "Envelope");
    }
}
