1. Create an instance of RemoteInput.Builder that you can add to your notification action.
2. Attach the RemoteInput object to an action using addRemoteInput().
// Key for the string that's delivered in the action's intent.
private static final String KEY_TEXT_REPLY = "key_text_reply";
String replyLabel = getResources().getString(R.string.reply_label);
RemoteInput remoteInput = new RemoteInput.Builder(KEY_TEXT_REPLY)
.setLabel(replyLabel)
.build();
// Create the reply action and add the remote input.
Notification.Action action =
new Notification.Action.Builder(R.drawable.ic_reply_icon,
getString(R.string.label), replyPendingIntent)
.addRemoteInput(remoteInput)
.build();

3. Applying the action to a notification and issue the notification.
// Build the notification and add the action.
Notification newMessageNotification =
new Notification.Builder(mContext)
.setSmallIcon(R.drawable.ic_message)
.setContentTitle(getString(R.string.title))
.setContentText(getString(R.string.content))
.addAction(action))
.build();
// Issue the notification.
NotificationManager notificationManager = NotificationManager.from(mContext);
notificationManager.notify(notificationId, newMessageNotification);

8. Swipe behaviour
for notifications.
Swiping the notification
shows a gear icon behind
which can be used to make
changes to when a
notification for the app
should be fired.

10. Android Wear
Notifications

11. Android Wear
Some of the visual updates and comparision between wear 1.x and wear 2.0
• Android Wear 2.0 updates the visual style of
notifications as well as introduces expanded
notifications, which provide substantial additional
content and actions in an app-like experience.
• Update touch targets of a notification.
• Dark background color.
• Updated horizontal swipe gesture on a notification

12. Expanded Notification
1. Adding additional content.
• To show additional content in your expanded notification, see Adding Pages to a
Notification.
• Additional content pages are stacked vertically in the expanded notification and
appear in the order they were added. These additional content pages can optionally
use a style such as BigTextStyle or BigPictureStyle.
2. Primary action
• The expanded notification will contain one primary action, which is the first action
in the notification unless a different action is specified using setContentAction().
3. Additional actions
• To specify additional actions, use addAction() or addActions(). The action drawer
of the expanded notification contains all available actions.

13. Smart Reply
// Create the reply action and add the remote input
NotificationCompat.Action action =
new NotificationCompat.Action.Builder(R.drawable.ic_reply_icon,
getString(R.string.label), replyPendingIntent)
.addRemoteInput(remoteInput)
// Allow generated replies
.setAllowGeneratedReplies(true)
.build();
