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();

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();

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.

Android WearNotifications

Android WearSome 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

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.
