Apps that support Android Auto 41 should show timely information to the driver only when it is relevant, and use 42 simple, predictable patterns for common tasks. 43</p> 44 45<p> 46 It's important that you test your auto app for the criteria listed on this page prior to 47 submitting to Google Play for review. There are two ways to test your app: 48</p> 49 50<ol> 51 <li> Use the Android Auto simulator to validate each checklist item. The simulator allows you to 52 sideload your app for testing. For more information on the simulator, see 53 <a href="{@docRoot}training/auto/start/index.html#test-it-dhu">Run and Test Auto Apps</a>.</li> 54 <li>Test your app in a vehicle by uploading your app to the alpha/beta channel on Google Play. 55 Apps will not work on Auto in vehicles unless they are installed from the Play Store. 56 For more information, see <a 57 href="{@docRoot}distribute/googleplay/developer-console.html#alpha-beta">Alpha and Beta Testing</a>. 58 </li> 59</ol> 60 61<p class="caution"> 62 <strong>Important:</strong> The criteria listed in this page apply to your app's user interface 63 and behavior when running on devices connected to an Android Auto screen.

Test 76 your app against those criteria to ensure that they meet Android standards for navigation and 77 design. Then test your app against all Auto-specific criteria, keeping in mind 78 that, when running on a device connected to Android auto, your app must meet the requirements 79 listed in this page. 80 81 82 83<div class="headerLine"> 84 <h2 id="ux"> 85 Visual Design and User Interaction 86 </h2> 87 88</div> 89 90<p> 91 These criteria ensure that your app follows critical design and interaction patterns 92 to ensure a consistent, intuitive, and enjoyable user experience on Android Auto. Many elements, 93 such as the navigation drawer, card backgrounds, fonts and icon colors, are set and rendered by 94 the system. Your own app-specific design elements must meet the following criteria when running 95 on a device connected to Android Auto. 96</p> 97 98<table> 99 100<tr> 101 <th style="width:2px;"> 102 Type 103 </th> 104 <th style="width:54px;"> 105 Test 106 </th> 107 <th> 108 Description 109 </th> 110</tr> 111 112<tr> 113 <td rowspan="5" id="safety"> 114 Driver Attention 115 </td> 116 117 <td id="AU-MV"> 118 AU-MV 119 </td> 120 <td> 121 <p style="margin-bottom:.5em;"> 122 App does not display on the Auto screen animated elements such as animated graphics, 123 video, or progress bars. 124 </p> 125 </td> 126</tr> 127 128<tr> 129 <td id="AU-VA"> 130 AU-VA 131 </td> 132 <td> 133 <p style="margin-bottom:.5em;"> 134 App does not display any form of visual or text advertising on the Auto screen.
