The rapid development of Android platform brings forward more severe challenge for message push technology. Traditional ways of push notification mainly contain Polling, SMS Push and IP Push. But for applications on Android platform, any of these push technology has its own shortcomings. Firstly, an analysis was conducted on various kinds of push mechanism on Android Platform. Then a push mechanism based on protocol MQTT was researched in detail. Finally it was implemented through coding with the help of open source tool Mosquitto supported by IBM. Experimental results showed that this way has a low power consumption and high efficiency and it could be used for applications steadily on Android platform.
