  You can use the <strong>Android Studio File &gt; Project Structure</strong> dialog box to

  change configuration settings for your Android Studio project. This dialog

  box is useful if you need to change some of the settings you chose when you

  created the project.

</p>

<p>

  The Project Structure dialog box contains the following sections:

</p>

<ul>

  <li>

    <strong>SDK Location:</strong> Sets the location of the JDK, Android SDK,

    and Android NDK that the project uses.

  </li>

  <li>

    <strong>Project:</strong> Sets version information for <a

    href="{@docRoot}tools/building/plugin-for-gradle.html">Gradle</a> and for

    the <a href="{@docRoot}tools/building/plugin-for-gradle.html">Android plugin

    for Gradle</a>.

  </li>

  <li>

    <strong>Developer Services:</strong> Contains settings for Android Studio

    add-in components from Google or third parties.

  </li>

  <li>

    <strong>Modules:</strong> Used to set or change various module-specific

    build settings, including the target and minimum SDK, the app signature,

    and library dependencies. Most importantly, this is where you change

    the settings for your project's <em>app</em> module.

  </li>

</ul>

<p>

  The following two sections provide information on the <a href=

  "#dev-svc">Developer Services</a> and <a href="#modules">Modules</a>

  sections.

</p>

  Developer Services

</h2>

<p>

  The <em>Developer Services</em> section of the <em>Project Structure</em>

  dialog box contains configuration pages

  for several services that you can be use with your app. This section

  contains the following pages:

</p>

<ul>

  <li>

    <strong>AdMob:</strong> Allows you to turn on Google's <a href=

    "https://developers.google.com/admob/" class="external-link">AdMob</a>

    component, which helps you understand your users and show them tailored

    advertisements.

  </li>

  <li>

    <strong>Analytics:</strong> Allows you to turn on <a href=

    "https://developers.google.com/analytics/" class="external-link">Google

    Analytics</a>, which helps you measure user interactions with your app

    across various devices and environments.

  </li>

  <li>

    <strong>Authentication:</strong> Allows users to use <a href=

    "https://developers.google.com/identity/sign-in/android/" class=

    "external-link">Google Sign-In</a> to sign in to your app with their Google

    accounts.

  </li>

  <li>

    <strong>Cloud:</strong> Allows you to turn on <a href=

    "https://www.firebase.com/" class="external-link">Firebase</a> cloud-based

    services for your app.

  </li>

  <li>

    <strong>Notifications:</strong> Allows you to use <a href=

    "https://developers.google.com/cloud-messaging/" class=

    "external-link">Google Cloud Messaging</a> to communicate between your app

    and your server.

  </li>

</ul>

<p>

  Turning on any of these services may cause Android Studio to add necessary

  dependencies and permissions to your app. Each configuration page lists these

  and other actions that Android Studio takes if you enable the associated service.

</p>

<h2 id="modules">

  Modules

</h2>

<p>

  The <em>Modules</em> settings section lets you change configuration

  options for each of your project's modules. This section contains one page

  for each module in your app. In many cases, the project has just a single

  module, named <em>app</em>. However, if your project targets multiple form

  factors, it might have several modules. For example, if your project contains

  both a tablet app and a wearable app, it might have two modules, named

  <em>mobile</em> and <em>wear</em>. For more information about project

  modules, see <a href=

  "{@docRoot}tools/projects/index.html#ApplicationModules">Android Application

  Modules</a>.

</p>

<p>

  Each module's settings page is divided into the following panes:

</p>

<ul>

  <li>

    <strong>Properties:</strong> Specifies the versions of the SDK and build

    tools to use to compile the module.

  </li>

  <li>

    <strong>Signing:</strong> Specifies the certificate to use to

    <a href="{@docRoot}tools/publishing/app-signing.html#sign-auto">sign your

    APK</a>.

  </li>

  <li>

    <strong>Flavors:</strong> Lets you create multiple build <em>flavors</em>, where

    each flavor specifies a set of configuration settings, such as the

    module's minimum and target SDK version, and the

    <a href="{@docRoot}tools/publishing/versioning.html">version code and

    version name</a>. For example, you might define one flavor that has a

    minimum SDK of 15 and a target SDK of 21, and another flavor that has a

    minimum SDK of 19 and a target SDK of 23.

  </li>

  <li>

    <strong>Build Types:</strong> Lets you create and modify build

    configurations, as described in <a href=

    "{@docRoot}tools/building/configuring-gradle.html">Configuring Gradle

    Builds</a>. By default, every module has <em>debug</em> and

    <em>release</em> build types, but you can define more as needed.

  </li>

  <li>

    <strong>Dependencies:</strong> Lists the library, file, and module

    dependencies for this module. You can add, modify, and delete dependencies

    from this pane. For more information about module dependencies, see

    <a href="{@docRoot}tools/building/configuring-gradle.html#declareDeps">Declare

    dependencies</a> in <a href=
