Once you have your project created, we'll see a few different things. The Android Studio editor has open two files MainActivity.java and activity_main.xml.
Android uses XML for layouts. It also has a built in editor that we'll be using. MainActivity.java is connected with the XML file (which we will look at more soon).
Note: You can change the view of your project with the dropdown. Currently it's on "Android" although I prefer the "Project" view. It's personal preference
Now let's look at our files. On the left you'll see a java directory and a res directory. In the java directory we'll put all of the logic for our program, as well as some premade tests. Each activity's code will be here.
In the res directory we'll contain all resources. This includes layouts, images, strings, and colors.
drawable -> All XML images
layout -> All of the layouts for our activities
mipmap -> Images
values -> Strings, colors, and styles (oh my)
