Android 在谷歌地图上绘制两点之间的路径
我正在安卓谷歌地图上工作。我经历了 如果距离超过200公里,我无法绘制两点之间的完整路径。如何在两点之间绘制完整路径?许可证是否存在任何问题,如果存在任何许可证问题,我如何获得许可证 感谢首次创建活动时调用的Android 在谷歌地图上绘制两点之间的路径,android,overlay,kml,google-maps-api-2,Android,Overlay,Kml,Google Maps Api 2,我正在安卓谷歌地图上工作。我经历了 如果距离超过200公里,我无法绘制两点之间的完整路径。如何在两点之间绘制完整路径?许可证是否存在任何问题,如果存在任何许可证问题,我如何获得许可证 感谢首次创建活动时调用的/***/ /** Called when the activity is first created. */ private List<Overlay> mapOverlays; private Projection projection; @Override pub

我使用Google map android API v2在两点之间绘制了一条路径。我在该链接上发布了它的解决方案。使用Google导航URI和源和目标lat/lon
