<p>Creating a unified look and feel throughout a user interface adds value to
your product. Streamlining the graphic style will also make the UI seem more
professional to the user.</p>

<p>This document shows you how to create icons for various parts
of your application’s user interface that fit the style set by the Android UI
team. Following these guidelines will help you to create a polished and unified
experience for the user.</p>

<p>To get started creating conforming icons more quickly, you can download
the Android Icon Templates Pack. For more information, see
<a href="#templatespack">Using the Android Icon Template Pack</a>.</p>

<h2 id="launcherstructure">Launcher icon</h2>

<p>A launcher icon is the graphic that represents your application on an Android
device’s Home screen. It is a simplified 3D icon with a fixed perspective. The
required perspective is shown in Figure 1.</p>

<h4 id="launcherstructure">Structure</h4>

<ul>
<li>The base of a launcher icon can face either the top view or the front
view.</li>

<li>The majority of a launcher icon’s surface should be created using the
launcher icon <a href="#launcherpalette">color palette</a>. To add emphasis, use
one or more bright accent colors to highlight specific characteristics.</li>

<li>All launcher icons must be created with rounded corners to make them look
friendly and simple—as shown in Figure 2.</li>

<li>All dimensions specified are based on a 250x250 pixel artboard size
in a vector graphics editor like Adobe Illustrator, where the icon fits within
the artboard boundaries.</li>

<li><strong>Final art must be scaled down and exported as a transparent 48x48 px
PNG file using a raster image editor such as Adobe Photoshop.</strong></li>

<li>Templates for creating launcher icons in Adobe Illustrator and Photoshop are
available in the Icon Templates Pack.</li>
</ul>

definition. A light source is placed slightly to the left in front of the icon,
and therefore the shadow expands to the right and back.</p>

<h4 id="launchersteps">Step by step</h4>

<ol>
  <li>Create the basic shapes with a tool like Adobe Illustrator, using the
angles described in <a href="#launcherstructure">Launcher icon: structure</a>.
The shapes and effects must fit within a 250x250 pixel artboard.</li>
  <li>Add depth to shapes by extruding them and create the rounded corners as
described for the launcher icon structure.</li>
  <li>Add details and colors. Gradients should be treated as if there is a light
source placed slightly to the left in front of the icon.</li>
  <li>Create the shadows with the correct angle and blur effect.</li>
  <li>Import the icon into a tool like Adobe Photoshop and scale to fit an image
size of 48x48 px on a transparent background.</li>
  <li>Export the icon at 48x48 as a PNG file with transparency enabled.</li>

<h2 id="menustructure">Menu icon</h2>

<p>Menu icons are graphical elements placed in the pop-up menu shown to users
when they press the Menu button. They are drawn in a flat-front perspective.
Elements in a menu icon must not be visualized in 3D or perspective.</p>

<h4>Structure</h4>

<ul>
<li>In order to maintain consistency, all menu icons must use the same
primary palette and the same effects. For more information, see the
menu icon <a href="#menupalette">color palette</a>. </li>

<li>Menu icons should include rounded corners, but only when logically
appropriate. For example, in Figure 3 the logical place for rounded corners is
the roof and not the rest of the building.</span></li>

<li>All dimensions specified on this page are based on a 48x48 pixel artboard
size with a 6 pixel safeframe.</li>

<li>The menu icon effect (the outer glow) described in <a
href="#menulight">Light, effects, and shadows</a> can overlap the 6px safeframe,
but only when necessary. The base shape must always stay inside the
safeframe.</li>

<li><strong>Final art must be exported as a transparent PNG file.</strong></li>

<li>Templates for creating menu icons in Adobe Photoshop are available in the
Icon Templates Pack.</li>

of a status bar icon shown Figure 7.</li>

<h2 id="listviewstructure">List view icon</h2>

<p>List view icons look a lot like dialog icons, but they use an inner shadow

used only in a list view. Examples include the Android Market application home
screen and the driving directions screen in the Maps application.</p>

<ul>
<li>A list view icon normally has a 1 px safeframe, but it is OK to use the
safeframe area for the edge of the anti-alias of a round shape. </li>

Photoshop. Keep 1 pixel of padding around the bounding box inside the template.

<h2 id="dodonts">General guidelines</h2>

<p>Below are some "do and don't" guidelines to consider when creating icons for
your application. By following the guidelines, you can ensure that your icons
will work well with other parts of the Android platform UI and will meet the
expectations of your application's users. </p>

<table style="margin:0px;padding:0px;">
<tr>
<td style="border:0;width:350px;">

<h4>Do...</h4>

<ul>
<li>Use a normal perspective. The depth of an object should be realistic.</li>
<li>Keep it simple! By overdoing an icon, it loses it purpose and
readability.</li>
<li>Use colors only when necessary. Mind that the base of a launcher icon should
be grey and feel solid. </li>
<li>Use the correct angles for the specific icon types.</li>
</ul>
</td>
<td style="border:0;width:350px;">

<h4>Don’t...</h4>

<ul>
<li>Use open elements like text alone as icons. Instead place those elements on
a base shape.</li>
<li>Use colors for your status bar notifications. Those are reserved for
specific phone-only functions.</li>
</ul>

<h2 id="templatespack">Using the Android Icon Templates Pack</h2>

<p>The Android Icon Templates Pack is a collection of template designs, filters,
and settings that make it easier for you to create icons that conform to the
general specifications given in this document. We recommend downloading the
template pack archive before you get started with your icon design.</p>

<p>The icon templates are provided in Adobe Photoshop and Adobe Illustrator file
formats, which preserves the layers and design treatments we used when creating the
standard icons for the Android platform. You can load the template files into any
compatible image-editing program, although your ability to work directly with the
layers and treatments may vary based on the program you are using.</p>

<p>You can obtain the Icon Templates Pack archive using the link below: </p>

<h3 id="menuapx">Standard menu icons</h3>

<p>Shown below are standard menu icons that are included in the Android platform
(as of Android 1.5). You can reference any of these icon resources from your
application as needed, but make sure that the action you assign to the icon is
consistent with that listed. Note that this is not a complete list of icons and
that the actual appearance of standard icons may change across platform
versions.</p>

<p>To reference one of the icons from your code, use
<code>android.R.drawable.&lt;icon_resource_identifier&gt;</code>. For example,
you can call a menu item's {@link android.view.MenuItem#setIcon(android.graphics.drawable.Drawable) setIcon()}
method and pass the resource name:</p>

<p style="margin-left:2em"><code>.setIcon(android.R.drawable.ic_menu_more);</code>.

<p>You could reference the same icon from a layout file using
<code>android:icon="@android:drawable/ic_menu_more"></code>.</p>

<p>To determine the resource ID for an icon listed below, hover over the icon or
simply look at image filenames, which use the format
"&lt;icon_resource_identifier&gt;.png".</p>
