是一个轨迹记录的功能
private boolean openWorkspace() {
m_Workspace = new Workspace();

info.setServer(path);
info.setType(WorkspaceType.SMWU);
boolean isOpen = m_Workspace.open(info);
if(!isOpen){
Toast.makeText(context,"打开失败",Toast.LENGTH_SHORT).show();
return false;
}
m_MapView = (MapView) findViewById(R.id.getTrack);
m_MapControl = m_MapView.getMapControl();
m_Map = m_MapControl.getMap();
m_Map.setWorkspace(m_Workspace);
/*m_Map.open(m_Workspace.getMaps().get(0));
String mapName = m_Workspace.getMaps().get(0);
m_Map.open(mapName);
Point2D point2D = new Point2D();
point2D.setX(116.004177318841);
point2D.setY(36.4349243801011);
m_MapControl.getMap().setScale(1.0 / 20000);

point2D = point2Ds.getItem(0);
m_Map.setCenter(point2D);
m_Map.refresh();
}*/
//加载高德矢量图 作为地图。0为矢量，1为影像
DatasourceConnectionInfo dsInfo = new DatasourceConnectionInfo();
dsInfo.setEngineType(EngineType.GaoDeMaps);
dsInfo.setDriver("WMTS");
dsInfo.setAlias("gaode");

m_Map.setCenter(new Point2D(12953693.6950684, 4858067.04711915));
m_Map.refresh();
mNavigation = m_MapControl.getNavigation();
mNavigation.setEncryption(new SuperMapPatent());
return true;
}
会显示资源文件不存在

注释掉mNavigation = m_MapControl.getNavigation(); mNavigation.setEncryption(new SuperMapPatent());会成功打开，和查看以往轨迹但是无法定位。
