Can you please share some sample code That would be very useful

rajesh · Answer

Simple GitHub gist would be fine slightly smiling face

solidogen · Answer

if you use room based paging source you can update this item in database then your paging flow will emit a change

rajesh · Answer

Hi I don t want to use room base paging source I just want to use network response without database caching

solidogen · Answer

modyfing items without db is kinda hard I suggest a simple dao with room fallback to destructive migration if you don t care about the tables

rajesh · Answer

But inserting items in db is time consuming for lots of data thus creating delay in ui That s why I want to avoid it

rajesh · Answer

Also please explain in a bit about this simple dao approach

solidogen · Answer

I was in your position a while ago I also tried not to use room but I m pretty glad I did time between clicking update button and seeing viewholder update is like 0 1s I guess
