<p>Last, Android N also adds new APIs that allow you to leverage system

decorations in your app’s customized notification views. These APIs help

ensure that the notification views share a consistent presentation with

standard templates.</p>

<p>This document highlights some of the key changes that you should take into

 account when using the new notification features in your apps.</p>

<h2 id="bundle">Bundled Notifications</h2>

<p>Android N provides developers with a new way to represent

 a queue of notifications: <em>bundled notifications</em>. This is similar to the

 a queue of notifications: <i>bundled notifications</i>. This is similar to the

  <a href="{@docRoot}/training/wearables/notifications/stacks.html">Notification

  Stacks</a> feature in Android Wear. For example, if your app creates notifications

  for received messages, when more than one message is received, bundle the

<h3 id="best-practices">Best practices for bundled notifications</h3>

<p>This section provides guidelines about when to use notification groups instead

of the {@link android.app.Notification.InboxStyle} notifications that have been available

 in earlier versions of the Android platform.</p>

of the {@link android.app.Notification.InboxStyle InboxStyle}

notifications that have been available in earlier versions of the

Android platform.</p>

<h3>When to use bundled notifications</h3>

<p>You should use notification groups only if all of the following conditions are

displaying a list of incoming messages, or an email app displaying a list of

received emails.</p>

<p>Examples of where a single notification (InboxStyle or BigTextStyle) is preferable

 include: Individual messages from a single person, or a list representation of

 single-line text items.</p>

<p>

Examples of cases where a single notification is preferable

 include individual messages from a single person, or a list representation of

 single-line text items. You can use

({@link android.app.Notification.InboxStyle InboxStyle} or

{@link android.app.Notification.BigTextStyle BigTextStyle}) to accomplish

this.

</p>

<h3 id ="post">Displaying bundled notifications</h3>

 The only action a Wear developer must take is to verify that the app behavior

 corresponds to the <a href="#best-practices">guidelines</a> described above.</p>

<p>

In order to support backwards compatibility, a developer should still post

an

{@link android.app.Notification.InboxStyle InboxStyle} or equivalent

notification representative for the whole

information content of the group. This applies to child notifications in

Android 5.0 (API level 21) and above.

</p>

<p> 

For convenience, apps can usually reuse the notification group summary

and define it as an

{@link android.app.Notification.InboxStyle InboxStyle} notification,

with each line corresponding to a child notification.
