09. Emojify in FriendlyChat App
With your function deployed, you should be able to see your chat messages in FriendlyChat emojify too. But you currently don't see that. The emojify cloud function does trigger, and you can see the updated message in the Firebase console. But exiting out of the app and opening it afterwards does display the updated chat message.
This sent message doesn't appear changed as expected
Remember that you have a simple implementation in the message database listener; you only implemented onChildAdded() database handler.
One way you can improve FriendlyChat so that your updated database messages are updated is to use the FirebaseUI Database library, which properly implements the child event listener for List Views and Recycler Views.
Once you update FriendlyChat to use FirebaseUI Database, new messages from the app will show up in the chat list as well as chat message updates from the emojify cloud function.
