Zoom phonesdk integration

I have facing issue to integrate zoom phone sdk to my android app. I was followed the steps of creating app in zoom portal here
Create an OAuth app, after add the module in my app I cannot make a call in my app . It navigate to register page, I cannot enter my details there it leads my app to crash. Is there any guide to integrate phonesdk to android app for making calls.

Hi @vinithadevi ,

Is this the guidance you followed? Phone SDK - Android - Get started

The guidance requires an SDK app for Android.
