We recommended that you don't set color for bridged notifications.
When Wear apps post local notifications, you can work around this by checking
- <a href="{@docRoot}training/basics/supporting-devices/platforms.html#version-codes">the API level of the device</a> they're running on and using an appropriate color

+<p>
+ Wear 2.0 now supports inline action, which allows users to take actions on a
+ notification from within the notification stream card. On Wear, the inline
+ action appears as an additional button displayed at the bottom of the notification.
+</p>
+<p>
+ Inline actions are optional but recommended for cases in which users are likely
+ to take an action on a notification after viewing the contents in the
+ notification stream card (without going to the
+ <a href= "{@docRoot}wear/preview/features/notifications.html#expanded">expanded notification</a>).
+ Examples of good use cases for inline action on a notification include: replying to a
+ text message, stopping a fitness activity, and archiving an email message.
+</p>
+
+<p>
+ A notification can provide only one inline action.
+ To display the inline action as an additional button in the notification, set
+ the <a href="https://developer.android.com/reference/android/support/v4/app/NotificationCompat.Action.WearableExtender.html#setHintDisplayActionInline(boolean)">{@code setHintDisplayActionInline()}</a>
+ method to true. When a user taps the inline action, the system invokes
+ the intent that you specified in the notification action.
+</p>
+
+<h3>Adding an inline action</h3>
+<p>
+ The following code example shows how to create a notification with an inline
+ reply action:
+</p>
+
+<ol>
+ <li>Create an instance of
+ <a href="https://developer.android.com/reference/android/support/v4/app/RemoteInput.Builder.html">{@code RemoteInput.Builder}</a></code>
+ that you can add to your notification action. This class's constructor accepts a
+ string that the system uses as the key for the text input. Later, your app
+ uses that key to retrieve the text of the input.
+
+<pre>
+String[] choices = context.getResources().getStringArray(R.array.notification_reply_choices);
+ choices = WearUtil.addEmojisToCannedResponse(choices);
+ RemoteInput remoteInput = new RemoteInput.Builder(Intent.EXTRA_TEXT)
+ .setLabel(context.getString(R.string.notification_prompt_reply))
+ .setChoices(choices)
+ .build();
+</pre>
+
+ </li>
+
+ <li>
+ Use the <a href="https://developer.android.com/reference/android/support/v4/app/NotificationCompat.Action.Builder.html#addRemoteInput(android.support.v4.app.RemoteInput)">{@code addRemoteInput()}</a>
+ method to attach the <ahref="https://developer.android.com/reference/android/support/v4/app/RemoteInput.html">{@code RemoteInput}</a>
+ object to an action.
+
+<pre>
+NotificationCompat.Action.Builder actionBuilder = new NotificationCompat.Action.Builder(
+ R.drawable.ic_full_reply, R.string.notification_reply, replyPendingIntent);
+ actionBuilder.addRemoteInput(remoteInput);
+ actionBuilder.setAllowGeneratedReplies(true);
+</pre>
+ </li>
+
+ <li>
+ Add a hint to display the reply action inline, and use the
+ <a href="https://developer.android.com/reference/android/support/v4/app/NotificationCompat.WearableExtender.html#addAction(android.support.v4.app.NotificationCompat.Action)">{@code addAction}</a>
+ method to add this action to the notification.
+
+<pre>
+// Android Wear 2.0 requires a hint to display the reply action inline.
+ Action.WearableExtender actionExtender =
+ new Action.WearableExtender()
+ .setHintLaunchesActivity(true)
+ .setHintDisplayActionInline(true);
+ wearableExtender.addAction(actionBuilder.extend(actionExtender).build());
+</pre>
+ </li>
+</ol>

<h2 id="expanded">Expanded Notifications</h2>
<p>Android Wear 2.0 introduces <i>expanded notifications</i>, which provide
substantial additional content and actions for each notification.
</p>
<h2 id="messaging">MessagingStyle</h2>
-<p>If you have a chat messaging app, your notifications should use
-<a href="{@docRoot}preview/features/notification-updates.html#style">{@code Notification.MessagingStyle}</a>,
- which is new in Android N. Wear 2.0 uses the chat messages included
- in a <a href="{@docRoot}preview/features/notification-updates.html#style">{@code MessagingStyle}</a> notification
-
- (see <a href="{@docRoot}preview/features/notification-updates.html#style">{@code addMessage()}</a>) to provide
- a rich chat app-like experience in the expanded notification.

list of choices that the developer provides in

+<p> Smart Reply provides users with a fast (single tap), discreet (no speaking aloud),
+ private (messages received by a user never leave the watch), and reliable (no
+ internet connection needed) way to respond to chat messages.
</p>
-<p>Responses generated by Smart Reply are shown in addition to those set using the
- <a href="{@docRoot}reference/android/support/v4/app/RemoteInput.Builder.html#setChoices(java.lang.CharSequence[])">{@code setChoices()}</a> method.
+<p>
+ Smart Reply responses are generated by an entirely on-watch machine learning
+ model using the context provided by the MessagingStyle notification. No user
+ notification data is sent to Google servers to generate Smart Reply responses.
</p>
+
<p>To enable Smart Reply for your notification action, you need to do the
following:
</p>
<ol>
- <li>Use <a href="{@docRoot}preview/features/notification-updates.html#style">{@code Notification.MessagingStyle}</a>.
+ <li>Use <a href="https://developer.android.com/reference/android/support/v4/app/NotificationCompat.MessagingStyle.html">{@code NotificationCompat.MessagingStyle}</a>.
</li>
- <li>Call the method {@code setAllowGeneratedReplies()} for the notification action.
- For more information, see the downloadable
- <a href="{@docRoot}preview/setup-sdk.html#docs-dl">API reference</a>.
+ <li>Call the method <a href="https://developer.android.com/reference/android/support/v4/app/NotificationCompat.Action.Builder.html#setAllowGeneratedReplies(boolean)">{@code setAllowGeneratedReplies(true)}</a>
+ for the notification action.
</li>
<li>Ensure that the notification action has a
<a href="{@docRoot}reference/android/app/RemoteInput.html">{@code RemoteInput}</a>
// 3) add an action with RemoteInput
.extend(new WearableExtender().addAction(action)).build();
</pre>
+
+<h3 id="images">Adding images to a MessagingStyle notification</h3>
+<p>
+ You can add images to a notification message by setting the appropriate MIME
+ type and placing the URI to the image in {@code NotificationCompat.MessagingStyle.Message.}
+ <a href="https://developer.android.com/reference/android/support/v4/app/NotificationCompat.MessagingStyle.Message.html#setData(java.lang.String, android.net.Uri)">{@code setData()}</a> method.
+</p>
+<p>
+ Here is the code snippet to set data of type image in a notification:
+</p>
+<pre>
+NotificationCompat.MessagingStyle.Message message = new Message("sticker", 1, "Jeff")
+ .setData("image/png", stickerUri);
+
+ NotificationCompat notification = new NotificationCompat.Builder()
+ .setStyle(new NotificationComapt.MessagingStyle("Me")
+ .addMessage(message)
+ .build());
+
+</pre>
+<p>
+ In the above code snippet the variable <code>stickerUri </code>is a Uri that
+ points to a publicly-accessible location, as described <a
+ href="https://developer.android.com/reference/android/support/v4/app/NotificationCompat.MessagingStyle.Message.html">here
+ </a>.
