How to retrieve the last document in a firebase collection?

To solve this, you need to use a query that should look like this:

FirebaseFirestore rootRef = FirebaseFirestore.getInstance();
Query query = rootRef.collection("High Volume")
    .orderBy("Time", Query.Direction.DESCENDING)
    .limit(1);
query.get().addOnCompleteListener(/* ... */);

This query will order the results according to the time property and will limit the results to one.
