摘要
文章对Android操作系统上的基于FileObserver技术的监听机制进行了分析,针对其监听结果不能获取访问对象的问题,提出了基于脚本命令的联合监听技术,并对提出的联合监听方式的关键技术与实现细节进行了详细阐述。实验测试在Android操作系统4.0的华为U8825D手机上进行,测试结果表明,基于脚本命令的联合监听技术可以获取访问文件对象的信息。最后,对该项技术进行了性能分析,并针对它的一些性能问题提出了改进方案。
In this paper, the Android operating system monitoring mechanism based on the technology of FileObserver is analyzed. In allusion to the problem of the surveillance results without information of the application that access the monitored file, the joint monitoring technology based on script command is put forward. The key technology and implementation methods on joint monitoring technology are elaborated in detail. This technology is tested on U8825D huawei mobile phone with Android OS 4.0. The result of the study shows that the joint monitoring technology based on script commands can get access to the information about the access applications. Finally, We analyze the performance of monitoring technology of the joint script command and put forward an improved scheme for some performance problems.
