Android Studio 4.0 Tutorial - Part 1

Build an Android app for users to purchase food from restaurants, created all with Android Studio and Kotlin. This 4.0 tutorial series picks up where we left off in Android Studio 3.6 which I released about two months ago. Nothing has changed in this version that makes the 3.6 tutorial obsolete so go back and watch it on my YouTube channel page.

Today let's build a RecyclerView and Adapter that displays a list of restaurants for the user to choose. We'll use a single XML layout and a Kotlin RecyclerView Adapter and ViewHolder for this.

If you want to become an Android Engineer then learning how to use RecyclerViews is a must. I've used it nearly every day for five years. It's very common.

Hi Mr.Malone, I face a problem that the button's id is not appearing in the autocomplete list. How to actually fix this? I am currently using Android Studio 4.1

Hi Daniel, I can not import restaurantsRecyclerView by just typing restaurantsRecyclerView in the fragment first kotlin file. Any tips for that?

Hi Daniel.
I love your tutorials on Android Development cos its well explained and easy to understand for me.
Am learn Android Development without having any coding background and am really struggling. Even the Android software interface looks broad to me and most tutorials i seen are not current like yours.

It's funny how every Part 1 gets hundreds of thousands of views on your channel, but parts 6, 7 etc. get only a couple thousand.

Looking forward to Android Studio 4.1 Tutorial Part 1 :D

Bonsoir, j'ai deux questions si vous pouviez m'y répondre. La première mes fichiers main_navigation et autre sont en rouge bleu ou vert qu'est ce légende de couleur. Mes fichiers sont passés rouge mais mon application peut quand même s'exercer. Comment les remettre en vert. Et deuxième question comment faire une copie ou une sauvegarde des fichiers de mon application.
