我们开始研究Skobbler地图,并使用我们在Skobbler帐户中生成的API密钥下载演示项目AndroidOpenSourceDemoGradle,并开始处理我们自己的纬度和经度值。
我们尝试使用方法launchRouteCalculation()
计算自定义路线,方法是以SKCordinate
的形式传递起始位置和结束位置。
在同一方法中,我们通过传递包含纬度和经度值的列表com.skobbler.ngx.routing.SKRouteManager.calculateRouteWithPoints()
对象以及SKPostion
对象来调用SKRouteSettings
。
我们尝试的代码
List pointsList = new ArrayList();
pointsList.add(new SKPosition(23.609239, 46.767936));
pointsList.add(new SKPosition(23.609149, 46.769281));
pointsList.add(new SKPosition(23.605704, 46.768879));
// set the route listener
SKRouteManager.getInstance().setRouteListener(this);
SKRouteSettings routeSettings = new SKRouteSettings();
//set route mode
routeSettings.setRouteMode(SKRouteMode.CAR_FASTEST);
SKRouteManager.getInstance().calculateRouteWithPoints(pointsList,routeSettings);
但我们以错误陈述
结束GPX轨道导航可用于企业许可的商业用途“和 应用程序中的JNI DETECTED ERROR:jmethodID为NULL。
我们在日志中遇到的确切错误声明如下

有人可以帮我们解决这个错误吗?
