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

效果图：

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'));}
