Convert DocumentReference to string format

Question

I am fetching a list of DocumentReference which I am fetching from firestore. It looks like this:

com.google.firebase.firestore.DocumentReference@4a69111d

However, I can't get the object using the above in the following code.

var loc = com.google.firebase.firestore.DocumentReference@4a69111d
var documentRef:DocumentReference = firestore.document(loc.toString())
            documentRef.get().addOnSuccessListener { document ->
                if (document != null) {
                    Log.d("SHARED_PREF_VM", "DocumentSnapshot data: ${document.data}")
                }
            })

Can I somehow convert com.google.firebase.firestore.DocumentReference@4a69111d to this form /cities/blr/areas/alpaca

That string is just the generic Java/JVM representation of an object when its implementation does not override toString(). It is mostly meaningless and useless to an application.

If you want to convert a DocumentReference to a string in order to use later as a DocumenReference, you should use the getPath() method on it. That will return a string which uniquely identifies that document. Then, you can turn that string back into a DocumentReference with firestore.document(), which.
