1 <body> 2 <p>Android allows applications to publish views to be embedded in other applications. These 3 views are called widgets, and are published by "AppWidget providers." The component that can 4 contain widgets is called a "AppWidget host." 5 </p> 6 <p>For more information, see the 7 <a href="{@docRoot}guide/topics/appwidgets/index.html">AppWidgets</a> 8 documentation in the Dev Guide.</p> 9 10 11 {@more} 12 13 14 <h2><a name="providers"></a>AppWidget Providers</h2> 15 <p>Any application can publish widgets. All an application needs to do to publish a widget is 16 to have a {@link android.content.BroadcastReceiver} that receives the {@link 17 android.appwidget.AppWidgetManager#ACTION_APPWIDGET_UPDATE AppWidgetManager.ACTION_APPWIDGET_UPDATE} intent, 18 and provide some meta-data about the widget. Android provides the 19 {@link android.appwidget.AppWidgetProvider} class, which extends BroadcastReceiver, as a convenience 20 class to aid in handling the broadcasts. 21 22 23 <h2>AppWidget Hosts</h3> 24 <p>Widget hosts are the containers in which widgets can be placed. Most of the look and feel 25 details are left up to the widget hosts. For example, the home screen has one way of viewing 26 widgets, but the lock screen could also contain widgets, and it would have a different way of 27 adding, removing and otherwise managing widgets.</p> 28 <p>For more information on implementing your own widget host, see the 29 {@link android.appwidget.AppWidgetHost AppWidgetHost} class.</p> 30 31 </body> 32 33
