Summary

In this chapter, we centered our efforts on creating a good offline experience for our user (storing the messages in a local database using Room) and providing a mechanism to store the messages backup, in case something fails. We have also learned how to use different providers to store our files in the cloud using Firebase Firestore and AWS S3.

Now, we have finished our work in the WhatsPackt app. In the next chapter, we will start building a new app: Packtagram. It will be an app to share photos and videos with our friends that will provide new and different challenges when creating it, such as capturing video. These are challenges that we will learn to overcome.
