Hi,

I just purchase a Mavic 2 pro with smart controller.
Then compile the sample code that is available on the developper site.
And install it into the smart controller using Android studio and debuger mode.

all runs fine, except waypoint mission V2.
the app crashes immediately.

smart controller is running Android 7.1.2, when the sample is done with API level 29.

Please find the log of the event below.

Thanks

Gildas Vallee.

Hi again gentlemen,

Please find more details on the error generated :

Thanks a lot for support.

java.lang.RuntimeException: Class WaypointV2MissionOperatorView is missing a constructor that takes Context
java.lang.RuntimeException: Could not dispatch event: class com.dji.sdk.sample.internal.model.ViewWrapper to handler [EventHandler public void com.dji.sdk.sample.internal.controller.MainActivity.onPushView(com.dji.sdk.sample.internal.model.ViewWrapper)]: Attempt to invoke interface method 'void dji.sdk.mission.waypoint.WaypointV2MissionOperator.addWaypointEventListener(dji.sdk.mission.waypoint.WaypointV2MissionOperatorListener)' on a null object reference

The fact that the application gets an error when launching Waypoints 2.0 on your drone is natural. All you need to do is read the DJI Mobile SDK Documentation carefully.

Because Mavic 2 doesn't support Waypoints 2.0. Waypoints 2.0 is only available on Matrice 300.

Sorry for disturbance, I posted the question too fast.
Class description is clear.
Next question I will look deeper before asking.

Please delete this post.
