Hello,
I am using Android GroundSDK version 7.4 with Anafi Ai.
Every time the drone lands i get a crash and this is the stack trace:

java.lang.NullPointerException: Attempt to invoke virtual method ‘com.parrot.drone.groundsdk.internal.http.HttpRequest com.parrot.drone.groundsdk.arsdkengine.http.HttpFdrClient.listLiteRecords(com.parrot.drone.groundsdk.internal.http.HttpRequest$ResultCallback)’ on a null object reference

Hello MichHighlander, I am facing the similar issue i.e. java.lang.IllegalStateException: FlightDataEngine not started yet. Did you found any workaround for this issue?

Hi,

Thank you for the (multiple) crash report(s).
There is nothing you can do to prevent those yet: those were three real bugs in our software and they will be fixed in next GroundSdk android release.

Regards,
