原标题:Communication between Android devices

I m looking for a way to allow a device to send secure notifications to another device with minimal battery loss. I am currently doing this using a SSLServerSocket however I feel like keeping a socket constantly open is very poor for battery life. The other option I considered was to just have a socket listening for a connection but I m not sure if this is any better. I need the notifications to be sent instantly so using a timer and connecting every x number of minutes is not optimal. Are there any good ways to achieve this over a wifi connection with minimal battery loss?

perhaps you can use C2DM (Cloud2DeviceMessaging). This may not be the perfect solution for you but instead of all the devices asking all the time for updates the server tells them they do.

装置A向装置B->发送电文; 装置A向服务器发送电文; 服务器通知装置B,它有电文; 装置B向服务器索取电文。
