Question

使用产品：iMobile 11i

问题描述：我使用如下代码将geoline3D对象gl添加到创建的KML图层

 private  GeoLine3D gl;
 private String layerKMlPath_c = android.os.Environment.getExternalStorageDirectory()
            + "/SuperMap/initKML/default.kml";


//调用代码
createFile(layerKMlPath_c);
scene.getLayers().addLayerWith(layerKMlPath_c,Layer3DType.KML,false,"轨迹路线");
Layer3D layer3d_c = scene.getLayers().get("轨迹路线");
Feature3D feature3D = new Feature3D();
feature3D.setGeometry(gl);
feature3D.toKMLFile(layerKMlPath_c);
layer3d_c.getFeatures().add(feature3D);

但是出现以下报错信息

请问我应该如何解决呢？

您好，根据报错提示空指针异常 建议查看下layer3d是否添加成功，另外看下MainActivity   674行对应的代码是否为layer3d_c.getFeatures().add(feature3D);，如果是这里报错，则检查是否添加kml图层成功

您好，问题已解决，问题出在我没有在SuperMap文件夹下新建initKML文件夹
