1.新建接口

public interface UpdateService {

    /**
     *更新接口
     * @param updatevo
     * @throws Exception
     */
    void UpdateClient(UpdateVO updatevo) throws Exception;
}

2.接口实现

/**
 * 更新接口的实现
 * Created by zyy on 2017/7/24.
 */
public class UpdateServicelmpl implements UpdateService{
    private Handler handler;

    private ServerDataExchangeUtil serverDataExchangeUtil;

    public UpdateServicelmpl(Handler handler) {
        this.handler = handler;
        init();

    }

    /**
     * 初始化
     */
    private void init() {
        try {
            serverDataExchangeUtil = new ServerDataExchangeUtil();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public void UpdateClient(UpdateVO updatevo) throws Exception {
        String url= Constant.UPDATEURL;
        if(null != url && !"".equals(url)) {
            String mac = Constant.MAC;
            url = "http://" + url + FunctionUtil.getFunctionList(FunctionListEnum.UpdateClient.toString());
            Map<String, Object> mapPara = new HashMap<>();
            mapPara.put("mac", mac);
            //创个userUser, 使之有token
            InstanceServiceUtil.writeMap(UserUser.class.toString(), new UserUser());
            serverDataExchangeUtil.handler = handler;
            serverDataExchangeUtil.PostValue(CommandEnum.UPDATA_CLIENT, FunctionListEnum.UpdateClient.toString(), url, mapPara,ContentTypeEnum.Text.getContentType());
        }
    }
}

3.接口实体

public class UpdateVO {
    //服务器中APP版本号
    private int serverVersionCode;
    private String url;

    public int getServerVersionCode() {
        return serverVersionCode;
    }

    public void setServerVersionCode(int serverVersionCode) {
        this.serverVersionCode = serverVersionCode;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }
}
