Are you using this library: https://www.b4x.com/android/forum/threads/dji-drones.75244/ ?

Are you testing it on a real device? Which one?

No, he is using my UI Version.
https://www.b4x.com/android/forum/threads/dji-drones-ui-use-dji-widgets-in-your-app.81007/#content

But unfortunately i do not know where to search for the problem as it is working for me.

Erel · Jul 4, 2017

Does the same issue happen with my library?

I am using a donmanfred library and I am trying to use the widgets, I wanted to combine your great work with donmafred's great work but when I use widgets, it it does not work for me, thanks.

Greetings, I use a phone Samsung’s GALAXY Mega(the screen is good and comfortable to watch), it has android 4.xxxx I think ... this will be the problem ... I use it to avoid the annoying permissions of android 6.xxx ....

PABLO2013 · Jul 4, 2017

Thanks Donmafred and tks Erel ... great work ... the problem was solved when using a phone with android 6 and enabling the application to have permissions ... I will continue with the tests ... now field (I bought A dji care for this ...), thanks

You can avoid runtimepermission using targetsdk set to 22

DonManfred · Jul 4, 2017

So the issue was related to the Device you was using?
