Each Support Library is backward-compatible to a specific Android API 28 level. This design means that your applications can use the libraries' features and still be 29 compatible with devices running Android 1.6 (API level 4) and up.</p> 30 31<p>This guide provides information about what features are enabled by the Support Libraries, 32 how to use them in your development environment and information about library releases.</p> 33 34 35<h2 id="overview">Overview</h2> 36 37<p>Including the Support Libraries in your Android project is considered a best practice for 38 application developers, depending on the range of platform versions your app is targeting 39 and the APIs that it uses. Using the features the libraries provide can help you improve the look of your 40 application, increase performance and broaden the reach of your application to more users. 41 If you use the Android 42 <a href="{@docRoot}tools/projects/templates.html">code template</a> tools, you will notice that 43 all the Android application templates include one or more of the Support Libraries by default.</p> 44 45<p>The Support Libraries each target a base Android API level and each provides a different set 46 of features. In order to effectively use the libraries, it is important to consider what features 47 you want to support and understand what features are supported by each library at what Android 48 API level. To get started, review the 49 <a href="{@docRoot}tools/support-library/features.html">Support Library Features</a> guide. 50 After that, go to the 51 <a href="{@docRoot}tools/support-library/setup.html">Support Library Setup</a> topic to 52 learn how to incorporate the Support Libraries into your application. For more details 53 about Support Library APIs, see the {@link android.support.v4.app android.support} 54 packages in the API reference.</p> 55 56 57<h2 id="revisions">Revisions</h2> 58 59<p>This section provides details about the Support Library package releases.</p> 60 61<div class="toggle-content opened"> 62 <p id="rev21"><a href="#" onclick="return toggleContent(this)"> 63 <img src="{@docRoot}assets/images/triangle-opened.png" class="toggle-content-img" alt="" 64/>Android Support Library, revision 21</a> <em>(October 2014)</em> 65 </p> 66 <div class="toggle-content-toggleme"> 67 <dl> 68 <dt>Changes for <a href="features.html#v4">v4 support library:</a></dt> 69 <dd> 70 <ul> 71 <li>Added support for {@link android.support.v4.app.Fragment} 72 transitions for devices running Android 5.0 (API level 21). 73 Be aware that transitions have no effect on devices running 74 Android 4.4 and lower. 75 </li> 76 <li>Added {@link android.support.v4.provider.DocumentFile} to ease 77 the transition from {@link java.io.File} 78 while working with document trees.
