How I mapped the food with the images (i.e. One in Storage, one in RealtimeDatabase, how do I identify which photo is of which food?) by having the same id as key. When saving to database, there is an unique id for each food, the same id applies to the image storage. Hence, when I inflate the recyclerView from realtime database, I can refer to the id and hence find the corresponding image, displaying it in the cardView using GlideAPP.
