问题描述
我想知道是否可以开发一个应用程序，当我通过无线调制解调器访问互联网时，该应用程序可以记录数据使用情况.
我拥有来自私有ISP的无线数据卡.我通过软件包随附的自己的应用程序连接到Internet.允许我以3.1 mbps的速度使用6GB的数据，超过限制后，网络的速度会降低，当然是免费使用的，而我只为那6GB支付租金.
我觉得6GB的数据使用量很快就完成了.我只想要一个工具来监视数据流量.出于兴趣，我想自己开发一个应用程序，我只需要一点指导.你们能帮我吗?
我的想法是每当我使用应用程序连接到互联网时，将接收到的数据和发送的详细信息记录在一个文本文件中.
Hi,
I was wondering if I could develop an application which would make a log for the data usage whenever I access internet through my wireless modem.
I own a wireless datacard from a private ISP. I connect to the internet through their own application which came with the package. I am allowed to use 6GB of data at 3.1 mbps and after exceeding the limit, the speed of the network decreases which of-course comes under free usage and I pay the rental only for that 6GB.
I felt that the 6GB of data usage gets completed quickly. I just want a tool to monitor the data traffic. As a matter of interest I wanted to develop an application by myself and I just need a little guidance. Could you guys kindly help me out?
My idea is to record the data received and sent details in a text file whenever I connect to the internet using their application.
