I have 2 fragments named "F1" and "F2". In these two fragment I have 2 different recycleviews named "RV1" and "RV2". RV1 gets the data from internet. RV2 gets the data from database. I am putting datas inside the database from RV1. There is no problem till this step. My problem is to notify the RV2 adapter after I put new data inside the database. I tried to use below code but it gives me the below eror.

RV2_adapter.MyAdapter.notifyDataSetChanged();
