A project in Android Studio contains one or more modules that keep your code organized into discrete units of functionality. This page shows how to start a new project.
Android Studio makes it easy to create Android apps for various form factors, such as phone, tablet, TV, Wear, and Google Glass. The New Project wizard lets you choose the form factors for your app and populates the project structure with everything you need to get started.
For more information about the Android project structure and module types, read Projects Overview. For more information on adding a module for a new device to an existing project, read Add a Module for a New Device.
If you didn't have a project opened, Android Studio shows the Welcome screen. To create a new project, click Start a New Android Studio project.
If you had a project opened, Android Studio shows the development environment. To create a new project, click File > New > New Project.
The next window lets you configure the name of your app, the package name, and the location of your project.
Enter the values for your project then click Next.
The next window lets you select the form factors supported by your app, such as phone, tablet, TV, Wear, and Google Glass. The selected form factors become the app modules within the project. For each form factor, you can also select the API Level for that app. To get more information, click Help me choose.
The Android Platform Distribution window shows the distribution of mobile devices running each version of Android, as shown in figure 2. Click on an API level to see a list of features introduced in the corresponding version of Android. This helps you choose the minimum API Level that has all the features that your apps needs, so you can reach as many devices as possible. Then click OK.
Then, on the Target Android Devices Window, once you've selected your form factors and API versions, click Next.
The next screen lets you select an activity type to add to your app, as shown in figure 4. This screen displays a different set of activities for each of the form factors you selected earlier.
Choose an activity type then click Next.
Note: If you choose "Add No Activity", click Finish to create the project.
The next screen lets you configure the activity to add to your app, as shown in figure 5.
Enter the activity name, the layout name, and the activity title. Then click Finish.
Android Studio creates the default structure for your project and opens the development environment. If your app supports more than one form factor, Android Studio creates a module folder with complete source files for each of them as shown in figure 6.
Now you are ready to develop your app. For more information, see the following links:
