android开发一个定位和轨迹播放的程序

最近很多的跑步app，大概功能就是点击“开始”就自动定位，然后记录位置，上传到服务端（也有不上传的），最后将运动的轨迹在地图上显示出来。因为开启gps一般是每3、5秒就记录一下当前的gps，为此需要一个本地数据库支持，可以将位置信息每隔3秒记录一次并保存到本地数据库，然后设置一个消息服务，定时10分钟后上传一次本地数据库到服务器端，同时可以删除本地数据以减少数据空间占用量。

以下是代码：

         * 获取SIM卡的IMSI码
         * SIM卡唯一标识：IMSI 国际移动用户识别码（IMSI：International Mobile Subscriber Identification Number）是区别移动用户的标志，
         * 储存在SIM卡中，可用于区别移动用户的有效信息。IMSI由MCC、MNC、MSIN组成，其中MCC为移动国家号码，由3位数字组成，
         * 唯一地识别移动客户所属的国家，我国为460；MNC为网络id，由2位数字组成，
         * 用于识别移动客户所归属的移动网络，中国移动为00，中国联通为01,中国电信为03；MSIN为移动客户识别码，采用等长11位数字构成。
         * 唯一地识别国内GSM移动通信网中移动客户。所以要区分是移动还是联通，只需取得SIM卡中的MNC字段即可

关于地图轨迹的展示可以使用百度或高德的api实现 ，比较简单，就不贴代码了。另外在地位的时候，会经常出现跳点，或有时回到超点，这个可以使用位置计算，如果在移动过程中当前点和上一点距离为0的话或很小，说明没有移动，可以不记录，以节省资源。
