<p>Android Studio provides wizards and templates that verify your system
requirements, such as the Java Development Kit (JDK) and available RAM, and configure default
settings, such as an optimized default Android Virtual Device (AVD) emulation and updated system
images. This document describes additional configuration settings you may want to use to
customize your use of Android Studio. </p>

<p>For specific documentation about emulator and device setup and use, see
<a href="{@docRoot}tools/devices/index.html">Managing Virtual Devices</a>,
<a href="{@docRoot}tools/device.html">Using Hardware Devices</a>, and
<a href="{@docRoot}tools/extras/oem-usb.html">OEM USB Drivers</a>. </p>


<h2 id="sdk-mgr">SDK Manager</h2>
<p>After the initial Android Studio installation and setup, use the
<a href="{@docRoot}tools/help/sdk-manager.html">SDK Manager</a> to verify and update the tools,
platforms, packages, and other components used by your apps. You can also use the
<strong>File</strong> &gt; <strong>Settings</strong> &gt;
<strong>Appearance & Behavior</strong> &gt; <strong>System Settings</strong> &gt;
<strong>Updates</strong> to configure the SDK Manager to automatically prompt whenever updates are
available. </p>

<p class="note"><strong>Note:</strong> You can also customize the <code>build.gradle</code> file
so each app uses a specific build chain and compilation options. For more information see,
<a href="{@docRoot}tools/building/configuring-gradle.html">Configuring Gradle Builds</a>.   </p>



<h2 id="update-channel">Update channels</h2>
<p>Android Studio provides four update channels to keep Android Studio up-to-date based on your
code-level preference:
<ul>
  <li><strong>Canary channel</strong>: Canary builds provide bleeding edge releases, updated
  about weekly. While these builds do get tested, they are still subject to bugs, as we want
  people to see what's new as soon as possible. This is not recommended for production.</li>
  <li><strong>Dev channel</strong>: Dev builds are hand-picked older canary builds that survived
  the test of time. They are updated roughly bi-weekly or monthly.</li>
  <li><strong>Beta channel</strong>: Beta builds are used for beta-quality releases before a
  production release.</li>
  <li><strong>Stable channel</strong>: Used for stable, production-ready versions.</li>
</ul>
</p>

<p>By default, Android Studio uses the <em>Stable</em> channel. Use
<strong>File > Settings > Appearance & Behavior System Settings > Updates</strong> to change your
channel setting. </p>



<h2 id="proxy">Proxy Settings</h2>
<p>Proxies serve as intermediary connection points between HTTP clients and web servers that add
security and privacy to internet connections.</p>

<p>To support running Android Studio behind a firewall, set the proxy settings for the
Android Studio IDE and the SDK Manager. Use the Android Studio IDE HTTP Proxy settings page to set
the HTTP proxy settings for Android Studio. The SDK Manager has a separate HTTP Proxy settings
page.</p>

<p>When running the Android Plugin for Gradle from the command line or on machines where
Android Studio is not installed, such as continuous integration servers, set the proxy settings
in the Gradle build file.</p>

<p class="note"><strong>Note:</strong> After the initial installation of the Android Studio bundle,
Android Studio can run with internet access or off-line. However, Android Studio requires an
internet connection for Setup Wizard synchronization, 3rd-party library access, access to remote
repositories, Gradle initialization and synchronization, and Android Studio version updates.</p>


<h3>Setting up the Android Studio Proxy</h3>
<p>Android Studio supports HTTP proxy settings so you can run Android Studio behind a firewall or
secure network. To set the HTTP proxy settings in Android Studio:</p>
<ol>
 <li>From the main menu choose <strong>File &gt; Settings &gt; Appearance & Behavior -- System
 Settings -- HTTP Proxy</strong>.

<li>In Android Studio, open the IDE Settings dialog.
  <ul>
     <li>On Windows and Linux, choose
     <strong>File &gt; Settings &gt; IDE Setting -- HTTP Proxy</strong>. </li>
     <li>On Mac, choose
     <strong>Android Studio &gt; Preferences &gt; IDE Setting -- HTTP Proxy</strong>. </li>
   </ul>
 The HTTP Proxy page appears.</li>
 <li>Select <strong>auto-detection</strong> to use an auto-configuration URL to configure the
 proxy settings or <strong>manual</strong> to enter each of the settings. For a detailed explanation
 of these settings, see
 <a href="https://www.jetbrains.com/idea/help/http-proxy.html">HTTP Proxy</a>. </li>
 <li>Click <strong>Apply</strong> to enable the proxy settings. </li>
</ol>

<h3>Android Plugin for Gradle HTTP proxy settings</h3>
When running the Android Plugin from the command line or on machines where Android Studio is not
installed, set the Android Plugin for Gradle proxy settings in the Gradle build file.</p>

<p>For application-specific HTTP proxy settings, set the proxy settings in the
{@code build.gradle} file as required for each application module.</p>
<pre>
apply plugin: 'com.android.application'

android {
    ...

    defaultConfig {
        ...
        systemProp.http.proxyHost=proxy.company.com
        systemProp.http.proxyPort=443
        systemProp.http.proxyUser=userid
        systemProp.http.proxyPassword=password
        systemProp.http.auth.ntlm.domain=domain
    }
    ...
}
</pre>



<p>For project-wide HTTP proxy settings, set the proxy settings in the
<code>gradle/gradle.properties</code> file. </p>

<pre>
# Project-wide Gradle settings.
...

systemProp.http.proxyHost=proxy.company.com
systemProp.http.proxyPort=443
systemProp.http.proxyUser=username
systemProp.http.proxyPassword=password
systemProp.http.auth.ntlm.domain=domain

systemProp.https.proxyHost=proxy.company.com
systemProp.https.proxyPort=443
systemProp.https.proxyUser=username
systemProp.https.proxyPassword=password
systemProp.https.auth.ntlm.domain=domain

...
</pre>


<p>For information about using Gradle properties for proxy settings, see the
 <a href="http://www.gradle.org/docs/current/userguide/build_environment.html">Gradle User Guide</a>.</p>

<p class="note"><strong>Note:</strong> When using Android Studio, the settings in the Android
Studio IDE HTTP proxy settings page override the HTTP proxy settings in the
<strong>gradle.properties</strong> file.</p>



<h3>SDK Manager HTTP Proxy Settings </h3>
<p>SDK Manager proxy settings enable proxy internet access for Android package and library
updates from SDK Manager packages. </p>

<p>To set the SDK Manager settings for proxy internet access, start the SDK Manager and open the
SDK Manager page. </p>

<ul>
   <li>On Windows, select <strong>Tools &gt; Options</strong> from the menu bar. </li>
   <li>On Mac and Linux, choose <strong>Tools &gt; Options</strong> from the system menu bar. </li>
 </ul>

<p>The Android SDK Manager page appears. Enter the settings and click <strong>Apply</strong>. </p>
