I have been using FirestoreRecyclerAdapter to display images of documents from the Firebase Storage for the past three years. The idea is to store the data for long-term use and automatically update the data when something changed from the Firebase Storage. I don't want to embed the images in the apk to reduce the file size.
However, when I transitioned from ViewPager to Navigation Drawer, the Firestore data seemed to be automatically deleted as soon as I close the app. I understand the limitation of Firestore as an online-first database.
So, what is the recommended android database to display images from Firebase Storage to the RecyclerView for long-term use?
