一种Android系统应用层推送中间件

An Application Layer Push Middleware for Android System

随着移动互联网的高速发展,传统的信息获取方式已不能满足应用实时性需求,为及时便捷地获取信息,移动应用广泛采用推送服务作为实时消息获取模式.但现有的推送服务存在网络信道独享、资源利用率低,不同推送方案差异较大、兼容性差、与业务逻辑过度耦合等不足.针对这些不足,并结合Android系统开放性带来的碎片化现状,提出一种应用层推送中间件解决方案,该中间件采用订阅发布模式实现不同应用间网络信道共享,推送消息路由转发功能,在中间件控制结构上,采用主从服务模式,并利用软件自适应算法提高推送服务驻留存活率.实验表明,推送中间件能够高效利用系统资源,大幅提高驻留存活率.

With the rapid development of mobile internet,traditional information acquisition methods can not meet the real-time requirements of applications.In order to obtain information in a timely and convenient manner,push service is widely used as a real-time message acquisition mode in mobile applications.However,the existing push services have some shortcomings,such as network channel exclusive,low resource utili zation,large differences between different push schemes,poor compatibility and over-coupling with business logic.In view of these shortcomings and the fragmentation situation brought by the openness of Android system,this paper proposes an application-level push middleware solution,which uses subscription publishing mode to achieve different middleware.In the middleware control structure,the master-slave service mode is adopted,and the software adaptive algorithm is used to improve the resident survival rate of push service.Ex periments show that push middleware can efficiently utilize system resources and greatly improve the resi dent survival rate.
