基于Android C2DM服务的云端推送研究与实现

Research and Implementation of Cloud Pushing Based on Android C2DM Service

在基于Android平台上的应用中,保持其Android终端与服务器端的数据同步十分关键。传统的信息pull方法实现了保持Android终端与服务器端数据同步,它需要每个Android终端定时的去服务器上扫描,查看服务器是否发布或有更新数据,与最新的数据同步,需要客户端大量的网络流量和手机电量。针对pull方法的不足,文中实现了一种基于An-droid的C2DM服务来进行消息的云端推送的方法。运用该方法成功地让客户端接收到了服务器端发送过来的数据更新消息,大量地节省了Android客户端的网络流量和手机电量。

It is very important to keep the data synchronization between the Android terminal and the server in the application which is based on Android platform. The traditional method of pulling implements keeping the data synchronization between the Android terminal and the server. Each Android terminal is needed to scan the server to see whether the data is published or updated by the server and to synchronize data. But it wastes a lot of network traffic and mobile phone battery. Against the traditional method＇s weekness, the method of cloud pushing based on the Android＇s C2DM service is implemented in this paper. The message of data updating is received from the server to the client by using this method. It saved much clients network traffic and mobile phone battery.
