Follow the <a href="icon_design_launcher.html">latest 39 launcher icon guidelines</a> instead. 40</p> 41 42<p>A Launcher icon is a graphic that represents your application on the device's 43Home screen and in the Launcher window.</p> 44 45<p>The user opens the Launcher by touching the icon at the bottom of the Home 46screen. The Launcher opens and exposes the icons for all of the installed 47applications. The user selects an application and opens it by touching the 48Launcher icon or by means of any hardware navigation controls available, such as 49a trackball or d-pad.</p> 50 51<p>As described in <a href="icon_design.html#icon-sets">Providing 52Density-Specific Icon Sets</a>, you should create separate icons for low-, 53medium-, and high-density screens. This ensures that your icons will display 54properly across the range of devices on which your application can be installed. 55See <a href="icon_design.html#design-tips">Tips for Designers</a> for 56suggestions on how to work with multiple sets of icons.</p> 57 58 59 60<h2 id="market">Application Icons on Google Play</h2> 61 62<p>If you are <a href="{@docRoot}distribute/index.html">publishing 63your application on Google Play</a>, you will also need to provide a 512x512 64pixel, high-resolution application icon in the <a 65href="http://play.google.com/apps/publish">developer console</a> at upload-time. 66This icon will be used in various locations on Google Play and does 67not replace your launcher icon.</p> 68 69<p>For tips and recommendations on creating high-resolution launcher icons that 70can easily be scaled up to 512x512, see 71<a href="{@docRoot}guide/practices/ui_guidelines/icon_design.html#design-tips"> 72Tips for Designers</a>.</p> 73 74<p>For information and specifications about high-resolution application 75icons on Google Play, see the following article:</p> 76 77<p style="margin-left:2em"><a 78href="http://market.android.com/support/bin/answer.py?answer=1078870"> 79 Graphic Assets for your Application (Google Play Help) »</a> 80 81 82 83 84<h2 id="icon5">Android 2.0 and Later</h2> 85 86<p>Starting with Android 2.0, launcher icons should be front-facing, instead of 87at a three-quarter perspective. The following guidelines describe how to design 88launcher icons for Android 2.0 (API Level 5) and later.</p> 89 90<h3 id="style5">Style</h3> 91 92<p>The launcher icons that you create should follow the general style principles 93below. The guidelines aren't meant to restrict what you can do with your icons, 94but rather they are meant to emphasize the common approaches that your icons can 95share with others on the device. Figure 1, at right, provides examples. </p> 96 97<div class="figure"> 98 <img src="{@docRoot}images/icon_design/IconGraphic_Icons_i.png" 99 width="340"> 100 <p class="img-caption"> 101 <strong>Figure 1.</strong> Example launcher icons for Android 2.0 and 102 greater. 103 </p> 104</div> 105 106<p>Clean and contemporary:</p> 107 108<ul> 109 <li>Launcher icons should be modern and sometimes quirky; they should not 110appear aged or ragged. You should avoid overused symbolic metaphors whenever 111possible.</li> 112</ul> 113 114<p>Simple and iconic:</p> 115<ul> 116 <li>Android Launcher icons are caricatural in nature; your icons should be 117highly simplified and exaggerated, so that they are appropriate for use at small 118sizes. Your icons should not be overly complicated. </li> 119 <li>Try featuring a single part of an application as a symbolic 120representation of the whole (for example, the Music icon features a speaker). 121</li> 122 <li>Consider using natural outlines and shapes, both geometric and organic, 123with a realistic (but never photorealistic) rendering. </li> 124 <li>Your icons <em>should not</em> present a cropped view of a larger 125image.</li> 126</ul> 127 128<p>Tactile and textured:</p> 129<ul> 130 <li>Icons should feature non-glossy, textured material.

You should size the icons <em>smaller than the actual bounds of the 157asset</em> to create a consistent visual weight and to allow for shadows. If 158your icon is square or nearly square, it should be scaled even smaller.</p> 159 160<p>In order to indicate the recommended size for the icon, each example in 161Figure 2 includes three different guide rectangles:</p> 162 163<ul> 164<li>The red box is the bounding box for the full asset.</li> 165<li>The blue box is the recommended bounding box for the actual icon. 166The icon box is sized smaller than the full asset box so that there is space to 167include shadows and allow for special icon treatments.</li> 168<li>The orange box is the recommended bounding box for the actual icon when 169the content is square. The box for square icons is smaller than that for other 170icons to establish a consistent visual weight across the two types.</li> 171</ul> 172 173<table> 174<tr> 175 176<td style="border:0;"> 177<ol class="nolist"> 178 <li>Launcher icon dimensions for high-density (<code>hdpi</code>) screens:</li> 179 <ol class="nolist"> 180 <li>Full Asset: 72 x 72 px</li> 181 <li>Icon: 60 x 60 px</li> 182 <li>Square Icon: 56 x 56 px</li> 183 </ol> 184 </li> 185</ol> 186</td> 187<td style="border:0;"> 188 <img src="{@docRoot}images/icon_design/launcher_size_hdpi.png" width="450"> 189</td> 190</tr> 191<tr> 192<td style="border:0;"> 193 <ol class="nolist"> 194 <li>Launcher icon dimensions for medium-density (<code>mdpi</code>) screens:</li> 195 <ol class="nolist"> 196 <li>Full Asset: 48 x 48 px</li> 197 <li>Icon: 40 x 40 px</li> 198 <li>Square Icon: 38 x 38 px</li> 199 </ol> 200 </li> 201</ol> 202</td> 203 204<td style="border:0;"> 205 <img src="{@docRoot}images/icon_design/launcher_size_mdpi.png" width="450"> 206</td> 207</tr> 208<tr> 209<td style="border:0;"> 210 <ol class="nolist"> 211 <li>Launcher icon dimensions for low-density (<code>ldpi</code>) screens:</li> 212 <ol class="nolist"> 213 <li>Full Asset: 36 x 36 px</li> 214 <li>Icon: 30 x 30 px</li> 215 <li>Square Icon: 28 x 28 px</li> 216 </ol> 217 </li> 218</ol> 219</td> 220 221<td style="border:0;"> 222 <img src="{@docRoot}images/icon_design/launcher_size_ldpi.png" width="450"> 223</td> 224</tr> 225 226<tr> 227<td style="border:0;"></td> 228<td style="border:0;"> 229 <p class="table-caption"><strong>Figure 2.</strong> 230 Launcher icon sizing and positioning inside the bounds of the 231 icon asset.</p> 232</td> 233</tr> 234 235</table> 236 237 238 239 240<h3 id="materialscolors5">Materials and colors</h3> 241 242<p>Launcher icons should make use of tactile, top-lit, textured materials. Even 243if your icon is just a simple shape, you should try to render in a way that 244makes it appear to be sculpted from some real-world material.</p> 245 246<p>Android launcher icons usually consist of a smaller shape within a 247larger base shape and combine one neutral and one primary color. Icons may 248use a combination of neutral colors but should maintain a fairly high level of 249contrast. Icons should not use more than one primary color per icon, if 250possible.</p> 251 252<p>Launcher icons should use a limited color palette that includes a range 253of neutral and primary colors. The icons should not be over-saturated.</p> 254 255<p>The recommended color palette to use for Launcher icons is shown in Figure 3. 256You can use elements of the palette for both the base color and the highlight 257color. You can use the colors of the palette in conjunction with a 258white-to-black vertical linear gradient overlay. This creates the impression 259that the icon is lit from above and keeps the color less saturated.</p> 260 261<img src="{@docRoot}images/icon_design/IconGraphic_Colors.png" width="530"> 262<p class="img-caption"> 263<strong>Figure 3.</strong> Recommended color palette for icons.</p> 264 265<p>When you combine the materials in Figure 4 with a color highlight from the 266recommended palette above, you can create materials combinations such as those 267shown in Figure 5.
