<p>The Eclipse ADT Bundle provides everything you need to start developing apps, including
the Android SDK tools and a version of the Eclipse IDE with built-in ADT
(Android Developer Tools) to streamline your Android app development.</p>

<p>If you didn't download the Eclipse ADT bundle, go <a href="{@docRoot}sdk/index.html"
><b>download the Eclipse ADT bundle now</b></a>, or switch to the
<a href="{@docRoot}sdk/installing/index.html?pkg=studio">Android Studio
install</a> or <a href="{@docRoot}sdk/installing/index.html?pkg=tools">stand-alone SDK Tools
install</a> instructions</i>.</p>

<div class="procedure-box">
<p><b>To set up the ADT Bundle:</b></p>
<ol>
<li>Unpack the ZIP file
(named {@code adt-bundle-&lt;os_platform>.zip}) and save it to an appropriate location,
such as a "Development" directory in your home directory.</li>
<li>Open the {@code adt-bundle-&lt;os_platform>/eclipse/} directory and launch
<strong>Eclipse</strong>.</li>
</ol>

<p class="caution"><strong>Caution:</strong> Do not move any of the files or directories
from the {@code adt-bundle-&lt;os_platform>} directory. If you move the {@code eclipse/}
or {@code sdk/} directory, ADT will not be able to locate the SDK and you'll
need to manually update the ADT preferences.</p>

<p>Eclipse with ADT is now ready and loaded with the Android developer tools, but there are still
a couple packages you should add to make your Android SDK complete.</p>

<p>Android Studio provides everything you need to start developing apps, including
the Android SDK tools and the Android Studio IDE (powered by IntelliJ) to

<p>Before you set up Android Studio, be sure you have installed
JDK 6 or greater (the JRE alone is not sufficient). To check if you
have JDK installed (and which version), open a terminal and type <code>javac -version</code>.
If the JDK is not available or the version is lower than 6,
<a href="http://www.oracle.com/technetwork/java/javase/downloads/index.html" class="external-link"

<p><b>To set up Android Studio on Windows:</b></p>
  <ol>
    <li>Launch the downloaded EXE file, {@code android-studio-bundle-&lt;version&gt;.exe}.</li>
    <li>Follow the setup wizard to install Android Studio.

    <p>On some Windows systems, the launcher script does not find where Java is installed.
      If you encounter this problem,
      you need to set an environment variable indicating the correct location.</p>
      <p>Select <strong>Start menu > Computer > System Properties >
      Advanced System Properties</strong>. Then open <strong>Advanced tab > Environment
      Variables</strong> and add a new system variable <code>JAVA_HOME</code> that points to
      your JDK folder, for example <code>C:\Program Files\Java\jdk1.7.0_21</code>.</p>
    </p>
    </li>

  </ol>


<p>The individual tools and
other SDK packages are saved within the Android Studio application directory.
If you need to access the tools directly, use a terminal to navigate into the application and locate
the {@code sdk/} directory. For example:</p>
<p><code>\Users\&lt;user&gt;\AppData\Local\Android\android-studio\sdk\</code></p>

    <li>Drag and drop Android Studio into the Applications folder.
      <p>
      Depending on your security settings, when you attempt to open Android Studio, you might
      see a warning that says the package is damaged and should be moved to the trash. If this
      happens, go to <strong>System Preferences > Security &amp; Privacy</strong> and under
      <strong>Allow applications downloaded from</strong>, select <strong>Anywhere</strong>.
      Then open Android Studio again.</p>

<p>Your download package is an executable file that starts an installer. The installer checks your machine
  for required tools, such as the proper Java SE Development Kit (JDK) and installs it if necessary.
  The installer then saves the Android SDK Tools into a default location (or you can specify the location).</p>

<ol>
<li>Double-click the executable ({@code .exe} file) to start the install.</li>
<li>Make a note of the name and location in which it saves the SDK on your system&mdash;you will need to
refer to the SDK directory later when using
the SDK tools from the command line.</li>

    development machine, you might find these resources helpful:

      <li><a href="https://help.ubuntu.com/community/Java">https://help.ubuntu.com/community/JavaInstallation</a></li>
    </ul>
  </li>
  <li>Here are the steps to install Java and Eclipse, prior to installing
  the Android SDK and ADT Plugin.
    <ol>
      <li><p>If you are running a 64-bit distribution on your development
      machine, you need to install additional packages first. For Ubuntu 13.10 (Saucy Salamander)
      and above, install the <code>libncurses5:i386</code>, <code>libstdc++6:i386</code>, and
      <code>zlib1g:i386</code> packages using <code>apt-get</code>:</p>
      <pre class="no-pretty-print">sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386</pre>
      <p>For earlier versions of Ubuntu, install the <code>ia32-libs</code> package using
      <code>apt-get</code>:</p>
      <pre class="no-pretty-print">apt-get install ia32-libs</pre>
      </li>
      <li>Next, install Java: <pre class="no-pretty-print">apt-get install sun-java6-jdk</pre></li>
      <li>The Ubuntu package manager does not currently offer an Eclipse 3.7
      version for download, so we recommend that you download Eclipse from
      eclipse.org (<a
      href="http://www.eclipse.org/downloads/">http://www.eclipse.org/downloads/</a>).
      A Java or RCP version of Eclipse is recommended.</li>
      <li>Follow the steps given in previous sections to install the SDK
      and the ADT plugin. </li>
