The direct reply action, introduced in Android 7. For example, you can use a direct reply action to let users reply to text messages or update task lists from within the notification.

Figure 3. Tapping the "Reply" button opens the text input. The direct reply action appears as an additional button in the notification that opens a text input. When the user finishes typing, the system attaches the text response to the intent you had specified for the notification action and sends the intent to your app.

Caution: If you re-use a PendingIntent , a user may reply to a different conversation than the one they thought they did. You must either provide a request code that is different for each conversation or provide an intent that doesn't return true when you call equals on the reply intent of any other conversation.

The conversation ID is frequently passed as part of the intent's extras bundle, but is ignored when you call equals. The system prompts the user to input a response when they trigger the notification action, as shown in figure 3. To receive user input from the notification's reply UI, call RemoteInput. This is necessary to hide direct reply UI and confirm to the user that their reply was received and processed correctly.

When working with this new notification, use the context that's passed to the receiver's onReceive method. You should also append the reply to the bottom of the notification by calling setRemoteInputHistory.

Notifications can include an animated progress indicator that shows users the status of an ongoing operation. Figure 4. The progress bar during and after the operation. If you can estimate how much of the operation is complete at any time, use the "determinate" form of the indicator as shown in figure 4 by calling setProgress max, progress, false.

The first parameter is what the "complete" value is such as ; the second is how much is currently complete, and the last indicates this is a determinate progress bar. As your operation proceeds, continuously call setProgress max, progress, false with an updated value for progress and re-issue the notification. At the end of the operation, progress should equal max. You can either leave the progress bar showing when the operation is done, or remove it. In either case, remember to update the notification text to show that the operation is complete.

To remove the progress bar, call setProgress 0, 0, false. To display an indeterminate progress bar a bar that does not indicate percentage complete , call setProgress 0, 0, true.

The result is an indicator that has the same style as the progress bar above, except the progress bar is a continuous animation that does not indicate completion. The progress animation runs until you call setProgress 0, 0, false and then update the notification to remove the activity indicator.

Then attach the alternative notification to the normal notification with setPublicVersion. However, the user always has final control over whether their notifications are visible on the lock screen and can even control that based on your app's notification channels.

To update this notification after you've issued it, call NotificationManagerCompat. If the previous notification has been dismissed, a new notification is created instead.
