The Direct reply is the feature where a user sends a message from the notification itself without using the app’s UI. Users can tap the notification to open your app or take an action directly from the notification. The direct reply feature was introduced in Android 7.
A notification is a message that Android displays outside your application to provide the user with reminders, communication from other people, or other timely information from your app. Users can tap the notification to open your app or take an action directly from the notification.
