Project View:
Shows all the files in the Project.
Click on the folder image in the top left corner to open and close this view.
Click on the files that you want to open to open them:
AndroidManifest.xml: This file describes all the components of your Android app and is read by the Android runtime system when your app is executed.
java: All your Java language files are organized here. The java folder contains three subfolders:
com.example.myfirstapp: This folder contains the Java source code files for your app.
com.example.myfirstapp (androidTest): This folder is where you would put your instrumented tests, which are tests that run on an Android device. It starts out with a skeleton test file.
com.example.myfirstapp (test): This folder is where you would put your unit tests. Unit tests don't need an Android device to run. It starts out with a skeleton unit test file. 3. Expand the res folder. This folder contains all the resources for your app, including images, layout files, strings, icons, and styling. It includes these subfolders:
drawable: All your app's images will be stored in this folder.
layout: This folder contains the UI layout files for your activities. Currently, your app has one activity that has a layout file called activity_main.xml. It also contains content_main.xml, fragment_first.xml, and fragment_second.xml.
menu: This folder contains XML files describing any menus in your app.
mipmap: This folder contains the launcher icons for your app.
navigation: This folder contains the navigation graph, which tells Android Studio how to navigate between different parts of your application.
values: This folder contains resources, such as strings and colors, used in your app.
Virtual Device (Emulator):
Android Studio allows you to create a virtual device that you can run your app on.
This virtual device will automatically be called whenever you run your app.
The panels on the right of the screen allows you to manage this device.
The triangle in the top middle of the screen allows you to run your app on this device.
Display Editor:
Open one of the XML files (Project > app > res > layout)
In the top right of the file there is 3 options that allow you to view this xml files in different ways
Select the far right option labeled Design
This will bring up a screen with different panels
