<p>Android allows applications to publish views to be embedded in other applications. These
|
||
|
|
views are called widgets, and are published by "AppWidget providers." The component that can
|
||
|
|
contain widgets is called a "AppWidget host."

|
<p>Any application can publish widgets. All an application needs to do to publish a widget is
|
||
|
|
to have a {@link android.content.BroadcastReceiver} that receives the {@link
|
||
|
|
android.appwidget.AppWidgetManager#ACTION_APPWIDGET_UPDATE AppWidgetManager.ACTION_APPWIDGET_UPDATE} intent,
|
||
|
|
and provide some meta-data about the widget. Android provides the
|
||
|
|
{@link android.appwidget.AppWidgetProvider} class, which extends BroadcastReceiver, as a convenience
|
||
|
|
class to aid in handling the broadcasts.

<h2>AppWidget Hosts</h3>
|
||
|
|
<p>Widget hosts are the containers in which widgets can be placed. Most of the look and feel
|
||
|
|
details are left up to the widget hosts. For example, the home screen has one way of viewing
|
||
|
|
widgets, but the lock screen could also contain widgets, and it would have a different way of
|
||
|
|
adding, removing and otherwise managing widgets.</p>
|
||
|
|
<p>For more information on implementing your own widget host, see the
|
||
|
|
{@link android.appwidget.AppWidgetHost AppWidgetHost} class.</p>
