The latest version of these tools is included in the 17 <a href="{@docRoot}sdk/index.html">SDK starter package</a> and installed in the 18 <code><sdk>/build-tools/</code> directory.</p> 19 20<p>You should always keep your Build Tools component updated by downloading the latest version 21 using the <a href="{@docRoot}tools/help/sdk-manager.html">Android SDK Manager</a>. By default, 22 the Android SDK uses the most recent downloaded version of the Build Tools. If your projects 23 depend on older versions of the Build Tools, the SDK Manager allows you to download and maintain 24 separate versions of the tools for use with those projects.</p> 25 26<p>To use a specific version of the Build Tools in your application project:</p> 27 28<div class="toggle-content closed"> 29<p style="margin-top:5px"><a href="#" onclick="return toggleContent(this)"> 30 <img src="/assets/images/triangle-closed.png" class="toggle-content-img" alt="" 31 />Using Eclipse</a></p> 32 33 <div class="toggle-content-toggleme"> 34 <ol> 35 <li>In the root folder of your application project, find the {@code project.properties} 36 file.</li> 37 <li>Open the file and specify the Build Tools version by adding a {@code buildtools} property 38 on a separate line: 39<pre> 40sdk.buildtools=17.0.0 41</pre> 42 </li> 43 </ol> 44 </div> 45</div> 46 47<div class="toggle-content closed"> 48<p style="margin-top:5px"><a href="#" onclick="return toggleContent(this)"> 49 <img src="/assets/images/triangle-closed.png" class="toggle-content-img" alt="" 50 />Using Android Studio</a></p> 51 52 <div class="toggle-content-toggleme"> 53 <ol> 54 <li>In the root folder of your application project, find the {@code build.gradle} 55 file.</li> 56 <li>Open the file and specify the Build Tools version by adding a {@code buildToolsVersion} 57 property to the {@code android} section: 58<pre> 59android { 60 ... 61 buildToolsVersion "17.0.0" 62 ... 63} 64</pre> 65 </li> 66 </ol> 67 </div> 68</div> 69 70 71<h2 id="notes">Revisions</h2> 72 73<p>The sections below provide notes about releases of the Build Tools.
