<h3 id="CreatingAnAvd">Creating an AVD</h3>
<p>To avoid some explanation that's beyond the scope of this document, here's the
basic procedure to create an AVD:</p>
<p>With ADT 0.9.2 and above, the Android AVD Manager provides a simple graphical interface
for creating and managing AVDs. (If you're using ADT version 0.9.1 or older, you must
use the <code>android</code> tool to create your AVDs&mdash;read the AVD guide to
<a href="{@docRoot}guide/developing/tools/avd.html#creating">Creating an AVD</a>.)
<p>To create an AVD with the Android AVD Manager:</p>
<ol>
<li>Open a command-line (e.g.,"Command Prompt" application on Windows, or "Terminal"
on Mac/Linux) and navigate to your SDK package's
<code>tools/</code> directory.</li>
<li>First, you need to select a Deployment Target. To view available targets, execute:
<pre>android list targets</pre>
<p>This will output a list of available Android targets, such as:</p>
<pre>
id:1
Name: Android 1.1
Type: platform
API level: 2
Skins: HVGA (default), HVGA-L, HVGA-P, QVGA-L, QVGA-P
id:2
Name: Android 1.5
Type: platform
API level: 3
Skins: HVGA (default), HVGA-L, HVGA-P, QVGA-L, QVGA-P
</pre>
<p>Find the target that matches the Android platform upon which you'd like
to run your application. Note the integer value of the <code>id</code> &mdash;
you'll use this in the next step.</p>
<li>Select <strong>Window > Android AVD Manager</strong>, or click the Android AVD Manager icon (a black device)
in the Eclipse toolbar.</p>
</li>
<li>Create a new AVD using your selected Deployment Target. Execute:
<pre>android create avd --name <em>&lt;your_avd_name&gt;</em> --target <em>&lt;targetID&gt;</em></pre>
<li>Next, you'll be asked whether you'd like to create a custom hardware profile.
If you respond "yes," you'll be presented with a series of prompts to define various aspects of the
device hardware (leave entries blank to use default values, which are shown in brackets). Otherwise,
press return to use all default values ("no" is the default).</li>
<li>In the Virtual Devices panel, you'll see a list of existing AVDs. Click <strong>New</strong>
to create a new AVD.</li>
<li>Fill in the details for the AVD.
<p>Give it a name, a platform target, an SD card image (optional), and
a skin (HVGA is default).</p>
</li>
<li>Click <strong>Create AVD</strong>.</li>
</ol>
<p>That's it; your AVD is ready. In the next section, you'll see how the AVD is used

<p>This page describes how to install the Android Early Look SDK and set up your
development environment.</p>
<p>If you encounter any problems during installation, see the
<a href="#installnotes">Installation Notes</a> at the bottom of
this page.</p>
<h4 style="margin-top">Upgrading?</h4>
<p>If you have already developed applications using an earlier version
of the Android SDK, please read <a href="upgrading.html">Upgrading the SDK</a>, instead.
</p>
<h2 id="Preparing">Preparing for Installation</h2>
<p>Before you begin, take a moment to confirm that your development machine meets the
<a href="requirements.html">System Requirements</a>.
</p>
<p>If you will be developing on Eclipse with the Android Development
Tools (ADT) Plugin &mdash; the recommended path if you are new to
Android &mdash; make sure that you have a suitable version of Eclipse
installed on your computer (3.4 or newer is recommended). If you need to install Eclipse, you can
download it from this location: </p>
<p style="margin-left:2em;"><a href=
"http://www.eclipse.org/downloads/">http://www.eclipse.org/downloads/</a
></p>
<p>A Java or RCP version of Eclipse is recommended. </p>
<h2 id="Installing">Installing the SDK</h2>
<p>Unpack the Android SDK .zip archive to a suitable location on your machine.
By default, the SDK files are unpacked into a directory named
<code>android_sdk_<em>&lt;platform</em>&gt;_<em>&lt;release&gt;</em></code>.
The directory contains a local copy of the documentation (accessible by opening
<code>documentation.html</code> in your browser) and the subdirectories
<code>tools/</code>, <code>add-ons/</code>, <code>platforms/</code>, and others. Inside
each subdirectory of <code>platforms/</code> you'll find <code>samples/</code>, which includes
code samples that are specific to each version of the platform.</p>
<p>Make a note of the name and location of the unpacked SDK directory on your system &mdash; you
will need to refer to the SDK directory later, when setting up the Android plugin or when
using the SDK tools.</p>
<p>Optionally, you may want to add the location of the SDK's primary <code>tools</code> directory
to your system <code>PATH</code>. The primary <code>tools/</code> directory is located at the root of the
SDK folder. Adding <code>tools</code> to your path lets you run Android Debug Bridge (adb) and
the other command line <a href="{@docRoot}guide/developing/tools/index.html">tools</a> without
needing to supply the full path to the tools directory. </p>
<ul>
<li>On Linux, edit your <code>~/.bash_profile</code> or <code>~/.bashrc</code> file. Look
for a line that sets the PATH environment variable and add the
full path to the <code>tools/</code> directory to it. If you don't
see a line setting the path, you can add one:</li>
<ul><code>export PATH=${PATH}:<em>&lt;your_sdk_dir&gt;</em>/tools</code></ul>
<li>On a Mac, look in your home directory for <code>.bash_profile</code> and
proceed as for Linux. You can create the <code>.bash_profile</code> if
you haven't already set one up on your machine. </li>
<li>On Windows, right-click on My Computer, and select Properties.
Under the Advanced tab, hit the Environment Variables button, and in the
dialog that comes up, double-click on Path (under System Variables). Add the full path to the
<code>tools/</code> directory to the path. </li>
</ul>
<p>Note that, if you update your SDK in the future, you
should remember to update your <code>PATH</code> settings to point to the new location, if different.</p>
<p>If you will be using the Eclipse IDE as your development environment,
the next section describes how to install the Android Development Tools (ADT) plugin and set up Eclipse.
If you choose not to use Eclipse, you can
develop Android applications in an IDE of your choice and then compile, debug and deploy using
the tools included in the SDK (skip to <a href="#next">Next Steps</a>).</p>
<h2 id="InstallingADT">Installing the ADT Plugin for Eclipse</h2>
<p>Android offers a custom plugin for the Eclipse IDE, called Android
Development Tools (ADT), that is designed to give you a powerful,
integrated environment in which to build Android applications. It
extends the capabilites of Eclipse to let you quickly set up new Android
projects, create an application UI, add components based on the Android
Framework API, debug your applications using the Android SDK tools, and even export
signed (or unsigned) APKs in order to distribute your application.</p>
<p>In general, using Eclipse with ADT is a highly recommended
approach to Android development and is the fastest way to get started.
(If you prefer to work in an IDE other than Eclipse,
you do not need to install Eclipse or ADT, instead, you can directly
use the SDK tools to build and debug your application&mdash;skip to <a href="#NextSteps">Next Steps</a>.)</p>
<p>Once you have Eclipse installed, as described in <a href="#setup">Preparing for
Installation</a>, follow the steps below to
download the ADT plugin and install it in your respective Eclipse
environment. </p>

</ol>
</td>
</tr>
</table>
<p>Now modify your Eclipse preferences to point to the Android SDK directory:</p>
<ol>
<li>Select <strong>Window</strong> &gt; <strong>Preferences...</strong> to open the Preferences
panel (Mac: <strong>Eclipse</strong> &gt; <strong>Preferences</strong>).</li>
<li>Select <strong>Android</strong> from the left panel. </li>
<li>For the <em>SDK Location</em> in the main panel, click <strong>Browse...</strong> and
locate your downloaded SDK directory. </li>
<li>Click <strong>Apply</strong>, then <strong>OK</strong>.</li>
</ol>
<p>Done! If you haven't encountered any problems, then you're ready to
begin developing Android applications. See the
<a href="#next">Next Steps</a> section for suggestions on how to start. </p>
<h3 id="Troubleshooting">Troubleshooting ADT Installation</h3>
<p>
If you are having trouble downloading the ADT plugin after following the steps above, here are
some suggestions: </p>
<ul>
<li>If Eclipse can not find the remote update site containing the ADT plugin, try changing
the remote site URL to use http, rather than https. That is, set the Location for the remote site to:
<pre>http://dl-ssl.google.com/android/eclipse/</pre></li>
<li>If you are behind a firewall (such as a corporate firewall), make
sure that you have properly configured your proxy settings in Eclipse.
In Eclipse 3.3/3.4, you can configure proxy information from the main
Eclipse menu in <strong>Window</strong> (on Mac, <strong>Eclipse</strong>) &gt;
<strong>Preferences</strong> &gt; <strong>General</strong> &gt;
<strong>Network Connections</strong>.</li>
</ul>
<p>
If you are still unable to use Eclipse to download the ADT plugin as a remote update site, you
can download the ADT zip file to your local machine and manually install the it:
</p>
<ol>
<li><a href="http://developer.android.com/sdk/preview/index.html">Download the ADT Plugin zip file</a> (do not unpack it).</li>
<li>Follow steps 1 and 2 in the default install instructions (above).</li>
<li>In Eclipse 3.3, click <strong>New Archive Site...</strong>. <br/>
In Eclipse 3.4, click <strong>Add Site...</strong>, then <strong>Archive...</strong></li>
<li>Browse and select the downloaded zip file.</li>
<li>Follow the remaining procedures, above, starting from steps 5.</li>
</ol>
<p>To update your plugin once you've installed using the zip file, you will have to
follow these steps again instead of the default update instructions.</p>
<h4>Other install errors</h4>
<p>Note that there are features of ADT that require some optional
Eclipse components (for example, WST). If you encounter an error when
installing ADT, your Eclipse installion might not include these components.
For information about how to quickly add the necessary components to your
Eclipse installation, see the troubleshooting topic
<a href="{@docRoot}guide/appendix/faq/troubleshooting.html#installeclipsecomponents">ADT
Installation Error: "requires plug-in org.eclipse.wst.sse.ui"</a>.</p>
<h4>For Linux users</h4>
<p>If you encounter this error when installing the ADT Plugin for Eclipse:
<pre>
An error occurred during provisioning.
Cannot connect to keystore.
JKS</pre>
<p>
...then your development machine lacks a suitable Java VM. Installing Sun
Java 6 will resolve this issue and you can then reinstall the ADT
Plugin.</p>
<h2 id="NextSteps">Next Steps</h2>
<p>Once you have completed installation, you are ready to
begin developing applications. Here are a few ways you can get started: </p>

<p>This document describes how to move your development environment and existing
Android applications from an Android 1.5 SDK to the Android 1.6 Early Look SDK.
If you are migrating applications from an SDK older than 1.5, please also read the upgrading
document available in the Android 1.5 SDK package.</p>
<p>There are several compelling reasons to upgrade, such as new SDK tools
that make developing more efficient and new APIs that allow you to expand the feature-set
of your applications. However, even if you or your applications don't require these enhancements,
it's important that you upgrade to ensure that your applications run properly on the upcoming
Android platform.</p>
<p>The Android 1.6 platform will soon be deployable to devices around the world.
If you have already released Android applications to the public, you should
test the forward-compatibility of your applications on the latest version of the platform
as soon as possible. It's unlikely that you'll encounter breakage in your applications, but
in the interest of maintaining the best user experience, you should take no risks.
So, please install the new Android SDK and test your applications on the new platform.</p>

<!--
<p>If you haven't yet downloaded the SDK, <a href="index.html">download from here</a>
and unpack it into a safe location.</p>

<p>Now that you have the Android 1.6 Early Look SDK,
you need to perform some of the regular installation steps.</p>
<p>If you had previously setup your <code>PATH</code> variable to point to the SDK tools directory,
then you need to update it to point to the new SDK. For example, for a
<code>.bashrc</code> or <code>.bash_profile</code> file:</p>
<pre>export PATH=$PATH:<em>&lt;your_sdk_dir></em>/tools</pre>

<!--
<p><em>If you installed ADT 0.9.2 with the Android 1.6 Early Look SDK, there have been
additional changes, so please continue with this guide and update ADT.</em></p>
-->
<p>A new ADT plugin (version 0.9.2) is required for the Android 1.6 Early Look SDK.
With ADT 0.9.2, you can still compile your applications against
multiple platform versions, such as Android 1.5. However, previous versions
of ADT will not work with the Android 1.6 Early Look SDK, so you must upgrade
to ADT 0.9.2.</p>
<p>If you're currently using a version of ADT <em>older</em> than version 0.9, then you must
uninstall ADT before you proceed (read how to

<h2 id="RunYourApps">Run Your Applications</h2>
<p>Now that you have installed the Android 1.6 Early Look SDK, we encourage you
to run each of your applications in an instance
of the emulator that's running the new Android 1.6 system image. It's possible (however, unlikely)
that you'll encounter unexpected behavior in your application when you run your applications on
the new system image. Whether you believe your application will be affected by
platform changes or not, it's very important that you test the application's
forward-compatibility.</p>
<p>To test forward-compatibility, simply run your application, as-is, on an instance of the Android
Emulator that uses an AVD targeted to "Android Donut (Preview)":</p>
<ol>
<li>Make no changes to your application code.</li>
<li>Create a new AVD that's targeted to the "Donut" platform.</li>
<li>Launch your application in an emulator running the new AVD.</li>
<li>Perform normal testing on your application to ensure everything works as expected.</li>
</ol>
<p>For more information on creating an AVD and launching your application refer to the
<a href="{@docRoot}guide/developing/eclipse-adt.html#Running">Eclipse guide to
Running Your Application</a> or the
<a href="{@docRoot}guide/developing/other-ide.html#Running">Ant guide to
Running Your Application</a>, depending on your development environment.</p>
<h2 id="ConvertYourApps">Convert Your Applications</h2>
<p>If you want to fully utilize new APIs introduced with the Android 1.6 Early Look SDK,
then you'll need to convert your application to compile against the new "Donut" platform.</p>
<p>First, you need to change the value of the <code>minSdkVersion</code> attribute in
the <code>&lt;uses-sdk></code> manifest element. While
running your application against the Donut platform included with the Early Look SDK, you
<strong>must</strong> set the <code>minSdkVersion</code> value to "Donut". For example:</p>
<pre>
&lt;manifest>
...
&lt;uses-sdk android:minSdkVersion="Donut" />
...
&lt;/manifest>
</pre>
<p>This value is required only while compiling against the Donut platform included with
the Android 1.6 Early Look SDK. Once the final SDK is made
available for Android 1.6, you will need to change this value.
For more information, read about the <a href="index.html#provisional">Framework API and
Provisional API Level</a>.</p>
<p>Once you've changed the <code>minSdkVersion</code> value in your application's manifest,
continue with the procedures below to convert your applications.</p>
<h3 id="EclipseUsers">Eclipse users</h3>
<ol>
<li>Right-click on the individual project (in the Package Explorer)
and select <strong>Properties</strong>.</li>
<li>In the properties, open the Android panel and select a new Project Build Target.
Select "Android Donut (Preview)" to target the new
platform (or "Google APIs" with the "Donut" platform if your application uses the Maps APIs).</li>
<li>Click <strong>Apply</strong>, then <strong>OK</strong>.</li>
</ol>
<p>Remember that you must create an AVD that targets the same platform in order to run the emulator.
Continue with the
<a href="{@docRoot}guide/developing/eclipse-adt.html#Running">Eclipse guide to
Running Your Application</a>. During the procedure to Running Your Application, select a "deployment
target" or the AVD that includes the "Donut" platform. If your application utilizes the Google Maps APIs (i.e.,
MapView), be certain to select a target that includes the Google APIs.</p>
<h3 id="AntUsers">Ant users</h3>
<p>Use the <code>android</code> tool (located in <code><em>your_sdk</em>/tools/</code>)
to create a new <code>build.xml</code> that references
the new platform target. To see a list of available targets, execute:</p>
<pre>android list targets</pre>
<p>Select the target <code>id</code> that corresponds to the "Donut" platform and pass it with the
<code>--target</code> parameter when updating your project. For example:</p>
<pre>android update project --path /path/to/my-project --target 2</pre>
<p>Remember that you must create an Android Virtual Device (AVD) that's targeted to the
same platform before you can run the updated application an instance
of the emulator. Please continue with the
<a href="{@docRoot}guide/developing/other-ide.html#Running">Ant guide to
Running Your Application</a>. During the procedure to Running Your Application, select a "deployment
target" for the AVD that includes the "Donut" platform.
If your application utilizes the Google Maps APIs (i.e.,
MapView), be certain to select a target that includes the Google APIs.</p>
