Androidiots Podcast 14 : Better RecylerViews with Zomato.
Zomato is an Indian search and discovery platform for restaurants, founded in 2008 by Deepinder Goyal and Pankaj Chaddah. It currently operates in 24 countries with more than 50 million downloads of its Android app.
Such scale requires an app to be dynamic enough to support various types of restaurants, cuisines of multiple locations. Hence the App needs to be developed at scale and be able to serve in all the possible forms.
We all know in Android this can be achieved with templatized nested Recyclerview and in this episode we have Sajal Gupta, Prateek and Yashika from Zomato's Android team, walk us through their journey with Recyclerview & its adapter and things that they do to make it highly performant and scalable.
Show Notes :
Generations of Recyclerview adapter at Zomato Android App.

Better RecyclerView Adapter(V2):
View model is abstracted which was previously coupled with the view but now view holder holds the view model. Hence the onbind() method is no more needed.
Better RecyclerView Adapter (V3):

Question : How to send the user interaction information in this new Adapter?
Hint : Take a closer look to onViewAttachedToWindow() method.
