Answer 2

Every application has two parts
1. Frontend
2. Backend

In android app development the front end is managed by Extensible Markup Language (XML), which is useful to design the front end of android application.
it's like CSS in web development.
It uses tags to define properties for views i.e. elements of UI.
You can design the front end using Photoshop and convert it into an UI later using XML.

Another part is Back end- back end can be handled using two native languages which are Kotlin and Java.
Google announced kotlin to be the official Android app development language in 2018.
It's easy to learn and implement.
You can learn Kotlin through IntelliJ idea IDE, the IDE is very supportive.

Android Studio is the official IDE for Android App development.
There are many tutorials on YouTube, you can learn there. Or you can purchase a course online.

Hope this answer helps you,
Good luck!
