You can use a SQLite database for storing the chats offline, watch this YouTube tutorial [this video] , it is extensive but you can skip through some parts. When downloading/sending chat messages, mirror them into your database and use the database and ONLY THE DATABASE as the data source for your RecyclerView (never let any online data directly go into the list, always store it in the database first and read it from the database when putting it into your layout). To improve performance, you can store relevant chat messages in memory (in a separate ArrayList for example) instead of always reading data from the DB that you just wrote into it .

yes , shared preference stores data in flat file . Database is designed to have fast CRUD on data. Also you can deserialize the json string only once and can store all the objects as row if you use sqlite or room . It will save you the cost of deserialising the object every time you fetch it from shared preference and also you can setup cache which will save your network call. Its a one time effort and it will pay you in long term . Tutorial on sqlite : [this video]
