Android app tutorial?

I want to make some general android / iOS apps such as

quiz app
wallpaper app
news app

those basic stuff. Where can I find good tutorial?
I prefer video :slight_smile:

Bubble may not be the best service for you if you are trying to create a native app. Thunkable has a similar no-code approach and is dedicated to building native apps. Their YouTube channel also has tutorials on the type of thing you’re looking for.
