| 摘 要： | 针对远程定位的应用需求,设计了一套基于Android4.4和百度地图的远程定位系统。首先利用注册机制,构建一个由5个线程和3个消息队列组成的支持多用户同时使用的服务器系统,然后针对Android4.4版本特点,阐述了如何使用Looper机制进行消息线程间传递,最后通过百度地图API和定位终端的位置信息,实现多用户的实时定位。实验表明,本系统结构合理、性能稳定。

| Abstract: | Aiming at the application requirement of the remote positioning, a remote positioning system is designed, which is based on Android4.4 and Baidu maps. Firstly, the system based the registration mechanism designs a server program, having 5 theads and 3 message queues, which can support multiple users at the same time. Secondly, according to the characteristics of Android4.4 version, the paper describes how to transmit messages using Looper. Finally,the system realizes real time positioning for multiple users through using API of Baidu maps and location information from positioning terminal. Test results show that the system has a reasonable structure and stable performance. |
