说明：

MapDevice，为AutoSDK抽象出来的地图设备的概念，用于和surfaceview进行绑定。一个surfaceview同一时刻只能绑定一个MapDevice。

销毁

MapService.createDevice - 关键参数

com.autonavi.gbl.map.model.EGLDeviceID赋值导

com.autonavi.gbl.map.model.DeviceAttribute.uiTaskDeviceId字段，未赋值多屏会出现异常。

取值

含义

EGLDeviceIDDefault

默认显示屏幕，主屏

EGLDeviceIDExternal1

扩展屏幕(第1个)

...


EGLDeviceIDExternal8

扩展屏幕(第8个)

com.autonavi.gbl.map.model.DeviceAttribute.isNeedAntialias

取值

含义

true

开

false

关

com.autonavi.gbl.map.model.DeviceAttribute.samples

取值

含义

2

2倍抗锯齿

4

4倍抗锯齿

其余值

需要系统支持，并不一定能设置成功

com.autonavi.gbl.map.model.DeviceAttribute.deviceWorkMode

取值

含义

com.autonavi.gbl.map.model.EGLDeviceWorkMode.EGLDeviceWorkMode_WithThreadWithEGLContextDrawIn

Auto SDK创建EGL环境，有帧率控制线程，HMI无需关注EGL相关创建流程，在Android上较为适用，建议外部设置此模式。

com.autonavi.gbl.map.model.EGLDeviceWorkMode.EGLDeviceWorkMode_WithoutThreadWithEGLContextDrawNotIn

Auto SDK创建EGL环境，无帧率控制线程，目前适用IOS平台，不建议外部设置此模式。

com.autonavi.gbl.map.model.EGLDeviceWorkMode.EGLDeviceWorkMode_WithThreadWithoutEGLContextDrawNotIn

HMI创建EGL环境，有帧率控制线程，目前适用于Liunx平台，和Windows平台，不建议外部设置此模式。

核心接口

// 创建\nMapDevice com.autonavi.gbl.map.MapService.createDevice(\n    @EGLDeviceID.EGLDeviceID1 int shareDeviceId,\n\tDeviceAttribute deviceAttr,\n\tIDeviceObserver pIDeviceObserver \n)\n\n// 销毁\nboolean com.autonavi.gbl.map.MapService.destroyDevice(MapDevice pIMapDevice)

    说明：函数详情，请复制函数名称到在线API搜索

调用示例

// 创建\nMapDevice mapDevice;\nDeviceAttribute devAttribute = new DeviceAttribute();\ndevAttribute.isNeedAntialias = true;\ndevAttribute.samples = 4;\ndevAttribute.uiTaskDeviceId = 0;\ndevAttribute.deviceWorkMode = EGLDeviceWorkMode_WithThreadWithEGLContextDrawIn;\nmapDevice = mapService.createDevice(EGLDeviceID.EGLDeviceIDDefault, devAttribute, this);\nServiceMgr.getServiceMgrInstance().setUiLooper(0, Looper.getMainLooper());\nmapDevice.addDeviceObserver(this); //地图设备观察者\n\n// 销毁\nif (mapDevice != null) {\n    mapDevice.removeDeviceObserver(this);\n}\nmapService.destroyDevice(mapDevice);\nmapDevice = null;
