Paging with Paging 3

The Paging library enables you to load large sets of data gradually and gracefully, reducing network usage and system resources. So we launched Paging 3.0 (now in alpha), a complete rewrite of the Paging 2 library using Kotlin coroutines (but still supporting Java users) and offering the features you asked for, like easier error handling, more flexibility to implement list transformations like map or filter, and support for list separators, headers, and footers.
In this talk we’ll go over the main Paging 3 components, see how they fit in an existing app architecture, how to implement them and integrate the most common data paging features.

I LOVE the way the Googlers, and others, have adapted to working from home! Nice job Florina & team ..

That Remote Mediator is quite interesting, should be designed outside paging, it can be even useful for case which is not using paging but want to rely on local db and fetch network when needing it.

This presentation style, architecture overview and snippets are an awesome way to present. Thank you for sharing this and improving paging on Android!

The Codelab is complex, really trying hard to understand what is going on.
I have studied several codelabs and most of them were easy to follow, but this is the most difficult one

Great video but you’d get an empty cursor error when finding bad dogs because all dogs are good dog some are just extra good

I feel that Android development is Extremely complex and is really aimed to Advanced users. Why is so hard to learn???

Wonderful, this is more than I expected.

Tested the codelab today...it was fantastic. Not only the listing part, but also the footer and header stuff was amazing. The built-in error handling stuff is also very helpful.
I hope that soon we can also get rid of this ExperimentalApi annotation. But nevertheless, the Paging 3 API is awesome.

EDIT: I wish your team could also tackle the Android Camera API stuff because building camera apps in Android is a pain in the a*?!.

The first header is not showing up working when is getting the data from the database because the before is no null. Any solution?

Is it possible to update one Doggo once the list is loaded?

For example, if user wants to rename a Doggo, the Doggo name should be updated. But I don't want to invalidate the whole list. Only that one Doggo. Like a typical application, the update process happens using an API call.

I find it difficult to do in Paging 2.0.

[mahdijavaheri]

I'v been expecting to see granular update feature in paging 3.0
not all projects work with database and network mix
is there any plan to incorporate this?

[babythedude]

Is the Paging library intended to only be used in a list? Is it possible to manually trigger it to load more? Like continually display more markers(item) on a map

[ArjunVerma-lqcf]

This is the way things should be explained

[aadityabrahmbhatt]

Waiting for a video on Jetpack Compose!

[aspixk]

I'll definitely try it, cause Paging 2.0 unfortunately sucks

[gaoliang]

It would be awesome if you can make a CRUD operations with Paging 3

[zhigangguo]

I can't find api to modify data set, for example get all load data set, remove one data item, change one data item value...

[vadzimv]

Thanks, seems like many new and useful features :)
BTW, should we rethrow cancellation exception on example from 3:33 ?

[HasanKhan-olno]

Last time I try paging 2 fully implemented it but when sorting and transforming fetch data to live data it suck so I have to change all implementation to old way. I am happy they added support for transformation and sorting.

[deviantstudio]

the api is still poor.
i would like having ability to invalidate specific page key, get access to whole data set, get currently loaded key in the callback, jump to specific key in the list etc etc etc
