Learning RxJava (for Android) by example

A presentation aimed at beginners who have heard about RxJava and want to see what all the fuss is about. Kaushik Gopal provides primers on RxJava and RxAndroid, then looks at implementing real-world use cases in Android with RxJava.

He also imparts this valuable piece of advice, the best way to learn something is to just starting doing it!

[amicloud_yt]

Best Tutorial of RxJava RxANdroid I've ever found over I got this sooo late... :(((
Kudos wanna work with are outstanding

[Mseenra]

this is actually well explain regardless of the video quality.

[harshawardhanupasani]

Very helpful video. Best 1 for beginners. I learned a lot and expecting more tech vdos from this guy. But 2 things I cannot resist to inform.
1. Video quality is very low. I could not read the code.
2. Whenever he is pointing to something pls highlight it in the video cause he is saying like - this here, this there - which we cannot understand in the video.

None the less, I am very satisfied and looking forward for more such tech videos. thank u

[bulatgabid]

Thank you for repeating the questions, that’s really helpful, but not all presenters do that. And great video!

[TheMariotavor]

WELL DONE Kaushik!!!

[ankitasaini]

The network example you given at the beginning....we can cancel the async task in onDestroy method of activity...then when we use rxjava..

[ralfoide]

Thanks for posting, a really good intro that is still valid even now that we have RxJava 2.

[kunalchauhan]

Thanks a lot Kaushik. This is the first time i learned the concept (of an hour) in one shot.

[pratikgupta]

What was the answer to the question - what is the exception that is thrown when you don't override the onError method?

[demofavorite]

Excellently explained . You made us to implement or concentrate on RxJava by explaining it interestingly

[LiranBarsisa]

AsyncTasks are usually used for ListView/RecyclerView.
How could it be replaced here?
Is it possible to cancel the work, including interrupting of the thread that does it?

Also, about loaders, the thing is that its result is saved after configuration change, so that the work continues safely even after you change orientation, and you can get it and notified about it after the re-creation of the Activity/Fragment, whether it has finished now or before.
I don't think RX can be a replacement for this either.

[evertvdbraak]

Awesome! I can only find very abstract examples of integers and strings but never a practical solution like Kaushik shows with the autocomplete example.

Maybe to straight forward but I would love to see another practical example of two different (background) operations with different return objects that wait on each other to finish using zip/flatmap.

Great video! Can we use Rxjava timer for google speech to text recognition in android?

[vkhooda]
