android/support is a reference to the old and no longer used Android Support library. Are you using the latest version of DJI library?

 

[PABLO2013]

Thanks Erel, yes of course, reinstall everything, b4a, jdk, sdk, and the dji library, as you indicate, I am already registered in dji, etc ... I can't really solve it, thanks

 

[DonManfred]

based on the error you are not using the latest version i guess.
OR you are not using AndroidX

I fear the first one; not using the newest Lib. The error suggests a missing dependecy to android-support

 

[PABLO2013]

thanks don manfred, AndroidX is installed with the latest version of b4a and what is recommended for proper installation or do I have to take more steps to get AndroidX, thanks

Greetings, this is the last thing that results after doing the updates, if you can help me, thanks

I recommend you to wait for the DJI library to be updated. It will be easier.

I'm waiting for DJI to support the Mavic Air and will then update it. It is expected to be supported this year.

 

[PABLO2013]

Thank you very much, I wish I could include Dji Ui, but thank you very much.

 

[DonManfred]

I wish I could include Dji Ui

DJI UI needs an update too. But as i do not own a Drone anymore (gave my drone to my nephews) you should not expect to get any more Updates on DJI UI.

 

[PABLO2013]

Thanks Don Manfred for your library even without updating it is good ... my nephews will not get my drone.
