航点任务中获取当前航点：wpMissionOperator?.addListener(object : WaypointMissionOperatorListener { override fun onDownloadUpdate(p0: WaypointMissionDownloadEvent) { } override fun onUploadUpdate(p0: WaypointMissionUploadEvent) { } override fun onExecutionUpdate(p0: WaypointMissionExecutionEvent) { MyApplication.targetPointIndex = p0.progress?.targetWaypointIndex?:-1 } override fun onExecutionStart() { lifecycleScope.launch(Dispatchers.Main) { viewModel.updateTask(taskId ?: 0, 64) } } override fun onExecutionFinish(p0: DJIError?) { MyApplication.targetPointIndex = 0 lifecycleScope.launch(Dispatchers.Main) { viewModel.updateTask(taskId ?: 0, 48) } } }) 按照这个写的，targetWaypointIndex取出来怎么是72,71,70，不应该是下标小于10的数字么？

  能不能把你其他的航点代码给我看看呢，targetWaypointIndex的取值范围是0到WaypointMission.MAX_WAYPOINT_COUNT - 1，你的WaypointMission.MAX_WAYPOINT_COUNT是多少呢呢？

  你的航点的定义代码，或者说你上传了多少个航点，有70多个吗？你的MAX_WAYPOINT_COUNT是多少？

  航点定义的对象：

  我测试了一下都是从1-2-3-4开始，怎么会出现70多的数字呢？你的航点也都不到10个。你测试下这个Sample看看是否有问题。 Link：https://github.com/dji-sdk/Mobile-SDK-Android/blob/master/Sample%20Code/app/src/main/java/com/dji/sdk/sample/demo/missionoperator/WaypointMissionOperatorView.java

  对比了一下代码，我们调用的是：

  WaypointMission.Builder().addWaypoint

  demo里是：
  WaypointMission.Builder().waypointList(waypointList).waypointCount(waypointList.size());
  是不是这两种用法导致的？

  这个我也无法确定，你可以先跑一下Sample看看有没有问题，如果你怀疑是这个函数的使用方法导致的可以测试一下。
