<!DOCTYPE html><!-- This page is a placeholder for generated extensions api doc. Note:
1) The <head> information in this page is significant, should be uniform
across api docs and should be edited only with knowledge of the
templating mechanism.
3) All <body>.innerHTML is genereated as an rendering step. If viewed in a
browser, it will be re-generated from the template, json schema and
authored overview content.
4) The <body>.innerHTML is also generated by an offline step so that this
page may easily be indexed by search engines.

<b>Caution:</b>
Don't depend on these experimental APIs.
They might disappear,
and they <em>will</em> change.
Also, the Chrome Developer Dashboard doesn't allow you to
upload extensions that use experimental APIs.
</p>
<h2 id="using">How to use experimental APIs</h2>
<ol>
<li>
Make sure you're using the
<a href="http://www.chromium.org/getting-involved/dev-channel">Dev channel</a>
of Google Chrome.
Although the experimental APIs might work in other versions,
we need your feedback on the latest incarnation of the APIs,
which you can find on the Dev channel.
</li>
<li>
Using the
<a href="http://code.google.com/chrome/extensions/dev/experimental.html">API documentation for the Dev channel</a>,
write the code for your extension.
</li>
<li>
Specify the "experimental"
<a href="manifest.html#permissions">permission</a>
in your extension's manifest, like this:
<pre>"permissions": [
<b>"experimental"</b>,
...
],
</pre>
</li>
<li>
Enable the experimental API in your browser.
You can do this in either of two ways:
<ul>
<li> Go to <b>chrome://flags</b>,
find "Experimental Extension APIs",
click its "Enable" link,
and restart Chrome.
From now on,
unless you return to that page and disable experimental APIs,
you'll be able to run extensions that use experimental APIs.
</li>
<li> Specify the <b>--enable-experimental-extension-apis</b> flag
each time you launch the browser.
On Windows, you can do this by modifying
the properties of the shortcut that you use to launch Google Chrome.
For example:
<pre><em>path_to_chrome.exe</em> <b>--enable-experimental-extension-apis</b></pre>
</li>
</ul>
</li>
<li>
<a href="http://groups.google.com/a/chromium.org/group/chromium-extensions/topics">Give us feedback!</a>
Your comments and suggestions help us
improve the APIs and decide
which ones should move from experimental to supported.
