Record Jitsi meeting on mobile (android) sdk

Can someone please tell me how to use record feature in jitsi on mobile (android) ask?
I have gone through a lot of answers but I’m unable to find proper steps.

I have linked my dropbox app as mentioned in the docs by changing the android manifest and strings.xml.
So I am able to sing into dropbox but the recording is not saved.
What should I do now?
