hi, I got an error when I tried to run java.lang.NullPointerException: Attempt to read from field 'android.view.View android.support.v7.widget.RecyclerView$ViewHolder.itemView' on a null object reference I am succeeded when create data but failed when I tried to show data, I did change it to accommodate more fields and not just 2 like in the example, is it because of that?

Спасибо ОООООЧЕНЬ помог

[@RaulSC9]

Good, on another occasion, I followed another tutorial to work with Firestore, but in the adapters, they used "FirestoreRecyclerAdapter" I think it makes the work easier. You could give your opinion on this. A greeting!

[@AtifSayings]

yeah sure you can use it
