  <strong>Warning:</strong> This document describes obsolete guidelines for
  creating launcher icons. Follow the <a href="icon_design_launcher.html">latest
  launcher icon guidelines</a> instead.
</p>

<p>A Launcher icon is a graphic that represents your application on the device's
Home screen and in the Launcher window.</p>

<p>The user opens the Launcher by touching the icon at the bottom of the Home
screen. The Launcher opens and exposes the icons for all of the installed
applications. The user selects an application and opens it by touching the
Launcher icon or by means of any hardware navigation controls available, such as
a trackball or d-pad.</p>

<p>As described in <a href="icon_design.html#icon-sets">Providing
Density-Specific Icon Sets</a>, you should create separate icons for low-,
medium-, and high-density screens. This ensures that your icons will display
properly across the range of devices on which your application can be installed.
See <a href="icon_design.html#design-tips">Tips for Designers</a> for
suggestions on how to work with multiple sets of icons.</p>



<h2 id="market">Application Icons on Google Play</h2>

<p>If you are <a href="{@docRoot}distribute/index.html">publishing
your application on Google Play</a>, you will also need to provide a 512x512
pixel, high-resolution application icon in the <a
href="http://play.google.com/apps/publish">developer console</a> at upload-time.
This icon will be used in various locations on Google Play and does
not replace your launcher icon.</p>

<p>For tips and recommendations on creating high-resolution launcher icons that
can easily be scaled up to 512x512, see
<a href="{@docRoot}guide/practices/ui_guidelines/icon_design.html#design-tips">
Tips for Designers</a>.</p>

<p>For information and specifications about high-resolution application
icons on Google Play, see the following article:</p>

<h2 id="icon5">Android 2.0 and Later</h2>

<p>Starting with Android 2.0, launcher icons should be front-facing, instead of
at a three-quarter perspective. The following guidelines describe how to design
launcher icons for Android 2.0 (API Level 5) and later.</p>

<h3 id="style5">Style</h3>

<p>The launcher icons that you create should follow the general style principles
below. The guidelines aren't meant to restrict what you can do with your icons,
but rather they are meant to emphasize the common approaches that your icons can
share with others on the device. Figure 1, at right, provides examples.  </p>

<div class="figure">

    width="340">
  <p class="img-caption">
    <strong>Figure 1.</strong> Example launcher icons for Android 2.0 and
    greater.
  </p>
</div>

<p>Clean and contemporary:</p>

<ul>
  <li>Launcher icons should be modern and sometimes quirky; they should not
appear aged or ragged. You should avoid overused symbolic metaphors whenever
possible.</li>
</ul>

<p>Simple and iconic:</p>
<ul>
  <li>Android Launcher icons are caricatural in nature; your icons should be
highly simplified and exaggerated, so that they are appropriate for use at small
sizes. Your icons should not be overly complicated. </li>
  <li>Try featuring a single part of an application as a symbolic
representation of the whole (for example, the Music icon features a speaker).
</li>
  <li>Consider using natural outlines and shapes, both geometric and organic,
with a realistic (but never photorealistic) rendering. </li>
  <li>Your icons <em>should not</em> present a cropped view of a larger
image.</li>
</ul>

<p>Tactile and textured:</p>
<ul>
  <li>Icons should feature non-glossy, textured material. See
  <a href="#materialscolors5">Materials and colors</a>, below, for more
  information.</li>
</ul>

<p>Forward-facing and top-lit:</p>
<ul>
  <li><em>New for Android 2.0 and later platforms</em>: Android Launcher
icons should be forward-facing, with very little perspective, and they
should be top-lit.</li>
</ul>

<p class="note"><strong>Note:</strong> Android applies separate text labels
using the application name when displaying launcher icons, so you should avoid
embedding text in your icon and instead focus on designing a distinct and
memorable icon.</p>



<h3 id="size5">Size and positioning</h3>

<p>Launcher icons should use a variety of shapes and forms that are scaled and
positioned inside the asset to create consistent visual weight with other
icons.</p>

<p>Figure 2 illustrates various ways of positioning the icon inside the
asset. You should size the icons <em>smaller than the actual bounds of the
asset</em> to create a consistent visual weight and to allow for shadows. If
your icon is square or nearly square, it should be scaled even smaller.</p>

<p>In order to indicate the recommended size for the icon, each example in
Figure 2 includes three different guide rectangles:</p>

<ul>
<li>The red box is the bounding box for the full asset.</li>
<li>The blue box is the recommended bounding box for the actual icon.
The icon box is sized smaller than the full asset box so that there is space to
include shadows and allow for special icon treatments.</li>
<li>The orange box is the recommended bounding box for the actual icon when
the content is square. The box for square icons is smaller than that for other
icons to establish a consistent visual weight across the two types.</li>
</ul>

<h3 id="materialscolors5">Materials and colors</h3>

<p>Launcher icons should make use of tactile, top-lit, textured materials. Even
if your icon is just a simple shape, you should try to render in a way that
makes it appear to be sculpted from some real-world material.</p>

<p>Android launcher icons usually consist of a smaller shape within a
larger base shape and combine one neutral and one primary color. Icons may
use a combination of neutral colors but should maintain a fairly high level of
contrast. Icons should not use more than one primary color per icon, if
possible.</p>

<p>Launcher icons should use a limited color palette that includes a range
of neutral and primary colors. The icons should not be over-saturated.</p>

<p>The recommended color palette to use for Launcher icons is shown in Figure 3.
You can use elements of the palette for both the base color and the highlight
color. You can use the colors of the palette in conjunction with a
white-to-black vertical linear gradient overlay. This creates the impression
that the icon is lit from above and keeps the color less saturated.</p>

<img src="{@docRoot}images/icon_design/IconGraphic_Colors.png" width="530">
<p class="img-caption">
<strong>Figure 3.</strong> Recommended color palette for icons.</p>

<p>When you combine the materials in Figure 4 with a color highlight from the
recommended palette above, you can create materials combinations such as those
shown in Figure 5. To get you started, the
<a href="{@docRoot}guide/practices/ui_guidelines/icon_design.html#templatespack">Icon Templates Pack</a>
includes a Photoshop file (<code>ic_launcher_template/example_materials.psd</code>)
that provides all of the default materials, colors, and gradients. </p>

<h3 id="effects5">Effects</h3>

<p>Launcher icons are flat and the perspective is straight-on, rather than at an
angle. A drop shadow is used to create a sense of depth. Launcher icons can use
varying textures and lighting effects, but must be lit directly from above
(straight down).</p>

<p>In order to maintain consistency, all launcher icons should use the same
drop shadow effect, as shown in Figure 6.</p>

<h2 id="icon1">Android 1.6 and earlier</h2>

<p>The following guidelines describe how to design launcher icons for Android
1.6 (API Level 4) and earlier. Launcher icons for Android 1.6 and below are
simplified 3D icons with a fixed perspective. The required perspective is shown
in Figure 8.</p>

<h3 id="structure1">Structure</h3>

<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="#palette1">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 8.</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 PNG file
using a raster image editor such as Adobe Photoshop. Do not include a background
color.</strong></li>

<li>Templates for creating icons in Adobe Photoshop are available in the <a
href="{@docRoot}guide/practices/ui_guidelines/icon_design.html#templatespack">Icon
Templates Pack</a>.</li>

<h3 id="style1">Light, effects, and shadows</h3>

<p>Launcher icons are simplified 3D icons using light and shadows for
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>
