我的android数据库应用程序在android 2.x中不工作

我有一个应用程序在android 4.x中运行平稳，但在android 2.x中运行不平稳。
我试图做的是从web服务中获取一些信息并存储在数据库中。 我该怎么办？ 这是产生错误的代码：

public String CallMethod(String methodName,ArrayList<ServiceParam> paramList) {
        String result = "default";
        SoapObject request = new SoapObject(namespace, methodName);
        PropertyInfo pi = new PropertyInfo();

        for(int i=0;i<paramList.size();i++){
            ServiceParam serviceParam;
            serviceParam = paramList.get(i);
            pi = new PropertyInfo();
            pi.setName(serviceParam.name);
            pi.setValue(serviceParam.value);
            pi.setType(serviceParam.type);
            request.addProperty(pi);
        }

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(url);
        try {
            androidHttpTransport.call(namespace+methodName, envelope);
            SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
            result= response.toString();
            output = result;

        } catch (Exception e) {
            Log.d("Ehsan", e.getMessage());
            Log.d("Ehsan", e.getLocalizedMessage());
            e.printStackTrace();
        }

        return result;
    }

这是我的日志猫：
