前序文档：交互时序

本节描述主图服务(MapService)的初始化，是主图服务可用前的必要步骤。区别于地图设备和地图视图创建。

关键参数

     com.autonavi.gbl.map.model.InitMapParam

成员

含义

dataPath

地图数据路径绝对地址

fontPath

basePath

基本数据路径地址URL，非特殊都写

http://mps.amap.com:80/

assetPath

调用示例

\n//初始化主图服务，在UI线程中初始化\nMapService mapService = (MapService) ServiceMgr.getServiceMgrInstance().getBLService(SingleServiceID.MapSingleServiceID);\nint mapServiceInit = mapService.isInit();\n\n\n//基础参数\nInitMapParam mapParam = new InitMapParam();\nmapParam.systemParam.dpi = 240;\nmapParam.systemParam.cpucorenum = 4;\nmapParam.systemParam.memory = 4;\nmapParam.systemParam.permitPreLoad = true;\nmapParam.systemParam.memoryRation = 1.0F;\n\nmapParam.systemParam.mobiletype = "";\nmapParam.systemParam.platform = "android";\nmapParam.systemParam.platform_version = "6.0";\nmapParam.systemParam.cpuname = "骁龙";\nmapParam.systemParam.gpuname = "骁龙";\n\nmapParam.dataPath = AutoConstant.DATA_DIR;\nmapParam.fontPath = "";\nmapParam.basePath = "http://mps.amap.com:80/";\nmapParam.indoorPath = "http://m5.amap.com/";\nmapParam.assetPath = AutoConstant.MAPASSET_DIR;\nmapParam.buildingHeight = -1.0F;\nmapParam.hardwareJsonParam = null;\nmapParam.configBuffer = CommonUtil.getMapConfigBuffer();//引擎配置文件deviceprofile.data文件内容读取\nmapService.initMap(mapParam);\n
