How to send an arraylist by ksoap?

Greetings I have a doubt when sending an array list by means of ksoap, so far I have sent simple data such as numbers, text but now I want to send a complete table stored in sqlite.

The first step I take is to read a whole table stored in sqlite by means of this function.

public ArrayList<String> GetAllValues(String aTable)
{
    list = new ArrayList<String>();
    db = getReadableDatabase();

    String selectQuery = "SELECT  * FROM " + aTable;

    SQLiteDatabase db = this.getReadableDatabase();

    Cursor cursor = db.rawQuery(selectQuery, null);

    if (cursor.moveToFirst())
    {
        do
        {
            list.add(cursor.getString(1));//latitud
            list.add(cursor.getString(2));//longitud
        }
        while (cursor.moveToNext());
    }
    if (cursor != null && !cursor.isClosed())
    {
        cursor.close();
    }
    return list;
}

Once the temin read and stored in the variable "list" I try to send it to a webservice through KSOAP2 for which I occupy this function. My question is how do I incorporate the varibale list so that all the data stored in it are sent correctly?

private class TareaWSInsercion1 extends AsyncTask<String, Integer, Boolean> {
    final String NAMESPACE = "http://prueba1.com/";
    final String URL = "http://prueba1.com/ServicioPrueba.asmx";
    final String METHOD_NAME = "MtdCoordenadas";
    final String SOAP_ACTION = "http://prueba1.com/MtdCoordenadas";

    protected Boolean doInBackground(String... params) {

        boolean resul = true;


        try {

            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);



            //request.addProperty("NOMBRE", Nombre);



            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.dotNet = true;
            envelope.setOutputSoapObject(request);
            HttpTransportSE transportSE = new HttpTransportSE(URL);
            try {
                transportSE.call(SOAP_ACTION, envelope);
                SoapPrimitive resultado_xml = null;
                resultado_xml = (SoapPrimitive) envelope.getResponse();
                String res = resultado_xml.toString();
                if (res.equals("1")) {
                    resul = true;
                } else {

                }
            } catch (Exception e) {
                resul = false;
            }
            return resul;
        } catch (Exception e) {

        }
        return resul;
    }
}

Thank you.
