Enter W2A as the activity name and main as the layout name, and click Finish to complete this step. Android Studio will respond that it is creating the project, then take you to the project workspace.
Figure 19. Android Studio workspace
The project workspace is organized around a menu bar, a tool bar, a work area, additional components that lead to more windows (such as a Gradle Console window), and a status bar. Also note the Tip of the Day dialog box, which you can disable if you like.
Accessing AVD Manager or SDK Manager from menu and tool bar
To access the traditional AVD Manager or SDK Manager, select Android from the Tools menu followed by AVD Manager or SDK Manager from the resulting pop-up menu (or click their tool bar icons).
The project and editor windows
When you enter the project workspace, W2A is identified as the current project, but you won't immediately see the project details. After a few moments, these details will appear in two new windows.
Figure 20. The project and editor windows
The project window is organized into a tree whose main branches are App and Gradle Scripts. The App branch is further organized into manifests, java, and res subbranches:
- manifests stores
AndroidManifest.xml, which is an XML file that describes the structure of an Android app. This file also records permission settings (where applicable) and other details about the app.
- java stores an app's Java source files according to a package hierarchy, which is
ca.javajeff.w2ain this example.
- res stores an app's resource files, which are organized into drawable, layout, mipmap, and values subbranches:
- drawable: an initially empty location in which to store an app's artwork
- layout: a location containing an app's layout files; initially,
main.xml(the main activity's layout file) is stored here
- mipmap: a location containing various
ic_launcher.pngfiles that store launcher screen icons of different resolutions
- values: a location containing
The Gradle Scripts branch identifies various
.gradle (such as
.properties (such as
local.properties) files that are used by the Gradle-based build system.
Branch names and directory/file names
Each branch/sub-branch corresponds to a directory name or to a file name. For example, res corresponds to the
res directory and strings.xml corresponds to the
