android - Android 中的 Skobbler map 自定义路线计算

Question

我们开始研究 Skobbler map ，并使用我们在 Skobbler 帐户中生成的 API key 下载了演示项目 AndroidOpenSourceDemoGradle，并开始研究我们自己的纬度和经度值。我们尝试使用 launchRouteCalculation() 方法通过以 SKCordinate 的形式传递起始位置和结束位置来计算自定义路线。
在相同的方法中，我们调用了 com.skobbler.ngx.routing.SKRouteManager.calculateRouteWithPoints()，方法是传递包含纬度和经度值的列表 SKPostion 对象以及 SKRouteSettings 对象。

我们尝试过的代码

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);

但我们以错误说明结束

GPX track navigation is available for commercial use with a enterprise license" and JNI DETECTED ERROR IN APPLICATION: jmethodID was NULL.

我们在日志中遇到的确切错误语句如下
