分享Android CellLocation源码，基于Rexsee对象的基站定位功能

转自 ：http://www.oschina.net/code/snippet_194999_7244#11570

使用Rexsee的基站定位（RexseeCellLocation对象）。

需注意：基站信息是来自运营商的，仿真器只能模拟网络延迟（-netdelay）、网速（-netspeed）、以及一些电话相关的操作，gsm<call|accept|busy|cancel|data|hold|list|voice|status>。还不能模拟信号。

1. [代码]代码段示例

function query(){
var loction = eval('('+rexseeCellLocation.getLastKnownLocation()+')');
var type = location.type.toLowerCase();
var mcc = parseInt(location.operator.substring(0,3));
var mnc = (type=='gsm')?parseInt(location.operator.substring(3)):location.systemId;
var cid= (type=='gsm')?location.cid:location.baseStationId;
var lac= (type=='gsm')?location.lac:location.networkId;
var postData="{\version\":\"1.1.0\",\"host\":\maps.google.com\",\"access_token\";\"2:k7j3G6LaL6u_lafw:4iXOeOpTh1glSXe\",
\"home_mobile_country_code\":"+mcc+",\"home_mobile_network_code\":"+mnc+",\"address_language\";\"zh_CN\",\"radio_type\";
\""+type+"\",\"request_address\":true,\"cell_towers\":[{\"cell_id\":+cid+",\"location_area_code\":+lac+",\"mobile_aountry_code\":
"+mcc+",\"mobile_network_code\":"+mnc+",\"timing_advance\":5555}]}";

alert(rexseeAjax.syncSubmit('http://www.google.com/loc/json',postData,'utf-8'));
}
