Saving Data on Android

Where to go from here?
You implemented adding, updating, and deleting functionalities in this chapter and 
you saw how you can use the Firebase console to achieve that. You can visit the 
official documentation 
https://firebase.google.com/docs/firestore/manage-data/add-
data
 to learn more about these operations.
You still don't have a way to test these functionalities. In "Chapter 18: Reading data 
from Cloud Firestore" you'll add the ability to listen for data updates in real time. 
You'll learn how to read data from the database and to do other data manipulation 
operations.
