everything that defines your workspace for an app, from source code and assets to test code and build configurations.</p> <p>When you start a new project, Android Studio creates the necessary structure for all your files and makes them visible in the <strong>Project</strong> window in Android Studio. To open the window, select <strong>View > Tool Windows > Project</strong>.</p> <p>This page provides an overview of the key components inside your project.</p> <h2 id="ApplicationModules" data-text="Modules" tabindex="-1">Modules</h2> <p>A <em>module</em> is a collection of source files and build settings that let you divide your project into discrete units of functionality. Your project can have one or many modules, and one module can use another module as a dependency. You can independently build, test, and debug each module.</p> <p>Additional modules are useful when creating code libraries within your own project or when you want to create different sets of code and resources for different device types, such as phones and wearables, but keep all the files scoped within the same project and share some code.</p> <p>To add a new module to your project, click <strong>File > New > New Module</strong>.</p> <p>Android Studio offers a few distinct types of modules:</p> <dl> <dt><strong>Android app module</strong></dt> <dd>Provides a container for your app's source code, resource files, and app-level settings, such as the module-level build file and Android Manifest file. When you create a new project, the default app module is named "app." <p>Android Studio offers the following types of app modules:</p> <ul> <li>Phone & Tablet</li> <li>Automotive</li> <li>Wear OS</li> <li>Television</li> <li>Baseline Profile Generator</li> <li>Benchmark</li> </ul> <p>Each module provides essential files and some code templates that are appropriate for the corresponding app or device type.</p> <p>For more information on adding a module, read <a href="/studio/projects/add-app-module">Add a module for a new device</a>.</p> </dd> <dt><b>Feature module</b></dt> <dd> Represents a modularized feature of your app that can take advantage of <em>Play Feature Delivery</em>. For example, with feature modules, you can provide your users with certain features of your app on demand or as instant experiences through <a href="/topic/google-play-instant/overview">Google Play Instant</a>. <p>Android Studio offers the following types of feature modules:</p> <ul> <li>Dynamic Feature Module</li> <li>Instant Dynamic Feature Library Module</li> </ul> <p>To learn more, read about <a href="/studio/projects/dynamic-delivery">Play Feature Delivery</a>.</p> </dd> <dt><strong>Library module</strong></dt> <dd>Provides a container for your reusable code, which you can use as a dependency in other app modules or import into other projects. Structurally, a library module is the same as an app module, but when built, it creates a code archive file instead of an APK, so it can't be installed on a device.</p> <p>In the <strong>Create New Module</strong> window, Android Studio offers the following types of library modules:</p> <ul> <li><b>Android Library:</b> Contains all file types supported in an Android project except native C++ code, including Java and Kotlin source code, resources, and manifest files. The build result is an Android Archive (AAR) file that you can add as a dependency for your Android app modules.</li> <li><b>Android Native Library:</b> Contains all file types supported in an Android project, similar to an Android Library. However, Android Native Libraries also can contain native C++ source code. The build result is an Android Archive (AAR) file that you can add as a dependency for your Android app modules.</li> <li><b>Java or Kotlin Library:</b> Contains only Kotlin or Java source files.
