I'm having some troubles with Facebook live API.
I try to get a camera stream from android to use it to create a facebook livestream.
I follow the official documentation to set my request parameters, but I don't know how to set the privacy field. The [official documentation](https://developers.facebook.com/docs/graph-api/reference/user/live_videos/) says that the privacy field is a `Privacy Parameter`, but I don't know what's the corresponding type in java for Android.

Does anyone's got a solution for me?
