android - 使用服务器中的 MS SQL 更新本地的主 SQLite 数据库表

Question

我想用服务器中的 MS SQL 数据库表更新我设备中的本地 SQLite 数据库表（masters）。这里正在使用 SOAP 服务。如果在服务器中插入了任何新值，则单击按钮时，它必须同步并更新表中的新值。我想知道怎么做，下面是我用来调用网络服务的方法。

这里 MANUFACTURERID 和 MANUFACTURERDESC 是我要更新的两列。

我使用以下链接作为参考，并且使用了一个 TaskAsync.java 类。我想知道我必须在该类中编写什么来调用 Web 服务。作为java新手，请帮助我如何进行同步。提前感谢

            Log.d("response",response);

将以下代码放入 doInbackground() 的异步任务中

public boolean getData() 
    {
        try
        {
            SoapObject soReturn ;
            String [] ParameterName = new String[2]; 
            String [] ParameterValue = new String[2];

            ParameterName[0] = "MANUFACTURERID";   
            ParameterValue[0] = manmasid;

            ParameterName[1] = "MANUFACTURERDESC";   
            ParameterValue[1] = manmas; 

                try

                    objWSConfig.SetURL(URL, WebService);
                    objWSConfig.SetSOAPAction(SoapAction, MethodName);
                    objWSConfig.SetWebService(WebService); 
                    objWSConfig.SetMethod(MethodName);

                    ws_Method = objWSConfig.getMethod();
                    ws_Namespace = objWSConfig.getNamespace();
                    ws_URL = objWSConfig.getURL(); 
                    ws_SOAPAction = objWSConfig.getSOAPAction();

                    SoapObject request = new SoapObject(ws_Namespace,ws_Method);

                    for(ArryIndex = 0 ; ArryIndex < ParameterName.length ; ArryIndex ++)
