@jd:body

<p>The sections below describe the system and software requirements for developing 
Android applications using the Android SDK. </p>

<h3>Supported Operating Systems</h3>
<ul>
  <li>Windows XP (32-bit), Vista (32- or 64-bit), or Windows 7 (32- or 64-bit)</li>
  <li>Mac OS X 10.5.8 or later (x86 only)</li>
  <li>Linux (tested on Ubuntu Linux, Lucid Lynx)
    <ul>
      <li>GNU C Library (glibc) 2.7 or later is required.</li>
      <li>On Ubuntu Linux, version 8.04 or later is required.</li>
      <li>64-bit distributions must be capable of running 32-bit applications. 
      For information about how to add support for 32-bit applications, see
      the <a href="installing.html#troubleshooting">Ubuntu Linux
      installation notes</a>.</li>
    </ul>
  </li>
</ul>

<h3>Supported Development Environments</h3>

<h4 style="margin-top:.25em"><em>Eclipse IDE</em></h4>
    <ul>
      <li>Eclipse 3.4 (Ganymede) or greater</li>
      <li>Eclipse <a href="http://www.eclipse.org/jdt">JDT</a> plugin (included
in most Eclipse IDE packages) </li>
      <li>If you need to install or update Eclipse, you can download it from <a
href="http://www.eclipse.org/downloads/">http://www.eclipse.org/downloads/</a>. 

      <p>Several types of Eclipse packages are available for each platform. For
developing Android applications, we recommend that you install one of these
packages: </p>
         <ul>
           <li>Eclipse IDE for Java Developers</li>
           <li>Eclipse Classic (versions 3.5.1 and higher)</li>
           <li>Eclipse IDE for Java EE Developers</li>
         </ul>
      </li>
      <li><a href="http://www.oracle.com/technetwork/java/javase/downloads/index.html">JDK 5 or JDK
6</a> (JRE alone is not sufficient)</li>
      <li><a href="eclipse-adt.html">Android Development Tools plugin</a>
(recommended)</li>
      <li><strong>Not</strong> compatible with Gnu Compiler for Java (gcj)</li>
    </ul>


<h4><em>Other development environments or IDEs</em></h4>
    <ul>
      <li><a href="http://www.oracle.com/technetwork/java/javase/downloads/index.html">JDK 5 or JDK
6</a> (JRE alone is not sufficient)</li>
      <li><a href="http://ant.apache.org/">Apache Ant</a> 1.8 or later</li>
      <li><strong>Not</strong> compatible with Gnu Compiler for Java (gcj)</li>
    </ul>
  </li>
</ul>

<p class="note"><strong>Note:</strong> If JDK is already installed on your development computer, please take a moment to make sure that it meets the version requirements listed above. In
particular, note that some Linux distributions may include JDK 1.4 or Gnu Compiler for Java, both of which are not supported for Android development. </p>

<h3>Hardware requirements</h3>

<p>The Android SDK requires disk storage for all of the components that you choose to install. The table below provides a rough idea of the disk-space requirements to expect, based on the components that you plan to use. </p>

<table>
<tr>
<th>Component type</th>
<th>Approximate size</th>
<th>Comments</th>

<td>SDK Tools</td>
<td>35 MB</td>
<td>Required.</td>

<tr>
<td>SDK Platform-tools</td>
<td>6 MB</td>
<td>Required.</td>
</tr>
<tr>
<td>Android platform (each)</td>
<td>150 MB</td>
<td>At least one platform is required.</td>
</tr>
<tr>
<td>SDK Add-on (each)</td>
<td>100 MB</td>
<td>Optional.</td>
</tr>
<tr>
<td>USB Driver for Windows</td>
<td>10 MB</td>
<td>Optional. For Windows only.</td>

<p>Note that the disk-space requirements above are <em>in addition to</em> those of the Eclipse IDE, JDK, or other prerequisite tools that you may need to install on your development computer.</p>
