<h2 id="Running">Running Your Application</h2>

<p><em>Wait!</em> Before you can run your application on the Android Emulator, 

<p>Before you can run your application on the Android Emulator, 

you <strong>must</strong> create an Android Virtual Device (AVD). 

An AVD is a configuration that specifies the Android platform to be used on the emulator.

You can read more in the <a href="{@docRoot}guide/developing/tools/avd.html">Android Virtual

<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>Your AVD is now ready and you can close the Android AVD Manager. 

In the next section, you'll see how the AVD is used

when launching your application on an emulator.</p>

<p>To learn more about creating and managing AVDs, please read the

<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 — the recommended path if you are new to

Android — 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>

<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>
