We will be calling an API that supports pagination and use it to implement infinite Scroll in Android. Paging Source defines the way to load data from network i.e. API. Once you have paging source setup - you can define a pager object that is used to define the configuration such as pageSize, maxSize. Paging Adapter is used to show this paging data inside recyclerview.

Pagination improves performance of the app by creating only required objects. Recycler view recycles view whereas pagination library creates only the required objects in the memory. Paging 3 Jetpack Component provides support to implement paging in Android. We have implemented it using HILT and MVVM Architecture Pattern. Learn by creating a simple example in Hindi.

Thanks for this video, I have few questions & I sent an email to you.
First of all, as per your codes, it is showing errors & build failed.. I am trying to get data from SQLite instead of APIs.

I think there is a logical issue in getRefreshKey() fun. First time this function will return null. Then the position of the page will be 1 and it's prevKey will be null and nextKey will be 2 as per the logic in fun load(). Again there will be callback to function getRefreshKey(). As per the logic in this function you minus 1 from the nextKey and it will become 1 and this value i will be used as a position in function load and this fuction will again request for the same page which we have already loaded. Correct me if I am wrong. you can check by this by debugging or dry run.

[RahulYadav-vswd]

fun getRefeshKey() always return 1 as per the logic inside it. So the fun load() will always load page 1. I have performed dry run. Pls Clear my doubt if I am wrong.

[RahulYadav-vswd]

ye getRefreshKey() function jo h ismey kiya anchor position mee plus 1 ya minus 1 hota h ya phir prevKey ya nextKey mee se plus ya minus karkey return hota h value. Agar anchor position mee plus 1 ya minus 1 hota h tab tu iss function ka logic sahi h hamey desired page milta nahi tu same page milega jo anchor position hold karta h.

Hello sir, hope you will read this comment.
I want to implement pagination for firebase's real-time database. Basically, I want to fetch a single model from the database and show it in viewpager2, after that when the user will scroll the screen it should fetch the model again from the database. After searching for 4 days on the internet, I am posting this comment in the hope that you can help me.
Questions->
1. we fetch data from the cloud in the repository class and here we are also calling PagingSource class from the repository, I can not imagining the flow of code.
2. What will be the key for LoadResult<?, Room>.
3. How to do it without DI.
