arcgis runtime .net 100.3加载本地slpk无法显示
１，从github下载最新arcgis runtime .net 100.3代码示例
2, 修改SceneLayerUrl示例代码如下：
public SceneLayerUrl()
{
InitializeComponent();
// Execute initialization
//Initialize();
//var camera = new Camera(26.3359413066498, 117.65144205681, 500, 0, 0, 71.17);
var splkAbsolutePath = @"E:\SourceCode\3D\JointCore\Released\ModuleJointDesktop\Data\I3S\SanMing\i3s.slpk";
LoadSceneLayerFromSLPK(MySceneView, splkAbsolutePath);
}
public void LoadSceneLayerFromSLPK(SceneView sceneView, string slpkPath)
{
if (!File.Exists(slpkPath))
throw new Exception("if(!File.Exists(slpkPath))");
if (null == sceneView.Scene)
CreateScene(sceneView);
Uri treespk = new System.Uri(slpkPath);
var sceneLayer = new ArcGISSceneLayer();
// add the scene layer to the scene
sceneLayer.Source = treespk;
sceneLayer.Name = "倾斜三维";
sceneLayer.Loaded += SceneLayer_Loaded;
//await sceneLayer.LoadAsync();
sceneView.Scene.OperationalLayers.Add(sceneLayer);//实景三维
}
public void CreateScene(SceneView sceneView)
{
m_sceneView = sceneView;
// Create new Scene
Scene myScene = new Scene();
// Set Scene's base map property
myScene.Basemap = Basemap.CreateImagery();
myScene.Basemap.BaseLayers[0].Name = "影像";
sceneView.Scene = myScene;
}
private void SceneLayer_Loaded(object sender, EventArgs e)
{
var arcGISSceneLayer = sender as ArcGISSceneLayer;
if (null == arcGISSceneLayer)
return;
var fullExtent = arcGISSceneLayer.FullExtent;
var center = fullExtent.GetCenter();
var camera = new Camera(center.Y, center.X, 500, 60, 0, 71.17);
m_sceneView.SetViewpointCameraAsync(camera);
}
３，调试代码发现SceneLayer_Loaded正常运行，arcGISSceneLayer.LoadStatus为Loaded,arcGISSceneLayer.LoadError为null
4,结果却是在界面上看不到包含加载的本地slpk的ArcGISSceneLayer。而相同代码在100.2.1是正常加载并显示的。其中slpk数据的wkid=4326
５，用最新arcgis earth加载相同slpk却能够正常显示在地球上，什么原因？

（1）确保slpk是由ArcGIS Pro生成的，如果是经过第三方软件生成的，那么在用android加载之前，首先使用ArcGIS Pro的“Validate Scene Layer Package" 工具进行验证，验证slpk是否报错，比如：空间参考丢失。
（2）在100.2.1中能够加载这个缺失空间参考的slpk，说明100.2.1对slpk的加载性能较好，而100.3对slpk丢失空间参考的情况要求严格，如果由不三方生成的slpk缺失空间参考，那么在android100.3.0中就不能加载。
（3）此外，经过测试发现最近发布的android100.4对slpk的加载性能得到进一步提升。
