| ↳ | [android.app.Notification.Builder](https://developer.android.com/reference/kotlin/android/app/Notification.Builder#) |
Builder class for `https://developer.android.com/reference/kotlin/android/app/Notification` objects.
Provides a convenient way to set the various fields of a `https://developer.android.com/reference/kotlin/android/app/Notification` and generate content views using the platform's notification layout template. If your app supports versions of Android as old as API level 4, you can instead use androidx.core.app.NotificationCompat.Builder, available in the [Android Support library](https://developer.android.com/tools/extras/support-library.html).
Example:
```kotlin
Notification noti = new Notification.Builder(mContext)
.setContentTitle("New mail from " + sender.toString())
.setContentText(subject)
.setSmallIcon(R.drawable.new_mail)
.setLargeIcon(aBitmap)
.build();
```

### Builder
Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
Builder(
context: Context!,
channelId: String!)
```
Constructs a new Builder with the defaults:
| Parameters ||
|---|---|
| `context` | [Context](https://developer.android.com/reference/kotlin/android/content/Context.html#)!: A `https://developer.android.com/reference/kotlin/android/content/Context.html#` that will be used by the Builder to construct the RemoteViews. The Context will not be held past the lifetime of this Builder object. |
| `channelId` | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)!: The constructed Notification will be posted on this `https://developer.android.com/reference/kotlin/android/app/NotificationChannel`. To use a NotificationChannel, it must first be created using `https://developer.android.com/reference/kotlin/android/app/NotificationManager#createNotificationChannel(android.app.NotificationChannel)`. |
## Public methods
### addAction
Added in [API level 20](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
open fun addAction(action: Notification.Action!): Notification.Builder
```
Add an action to this notification. Actions are typically displayed by the system as a button adjacent to the notification content.
Every action must have an icon (32dp square and matching the [Holo Dark action bar](https://developer.android.com/design/style/iconography.html#action-bar) visual style), a textual label, and a `https://developer.android.com/reference/kotlin/android/app/PendingIntent`.
A notification in its expanded form can display up to 3 actions, from left to right in the order they were added. Actions will not be displayed when the notification is collapsed, however, so be sure that any essential functions may be accessed by the user in some other way (for example, in the Activity pointed to by `https://developer.android.com/reference/kotlin/android/app/Notification#contentIntent:android.app.PendingIntent`).
| Parameters ||
|---|---|
| `action` | [Notification.Action](https://developer.android.com/reference/kotlin/android/app/Notification.Action)!: the action to add |
| Return ||
|---|---|
| `https://developer.android.com/reference/kotlin/android/app/Notification.Builder#` | This value cannot be `null`. |

```
open fun addAction(
icon: Int,
title: CharSequence!,
intent: PendingIntent!
): Notification.Builder!
```
**Deprecated:** *Use `https://developer.android.com/reference/kotlin/android/app/Notification.Builder#addAction(android.app.Notification.Action)` instead.*
Add an action to this notification. Actions are typically displayed by the system as a button adjacent to the notification content.
Every action must have an icon (32dp square and matching the [Holo Dark action bar](https://developer.android.com/design/style/iconography.html#action-bar) visual style), a textual label, and a `https://developer.android.com/reference/kotlin/android/app/PendingIntent`.
A notification in its expanded form can display up to 3 actions, from left to right in the order they were added.

As of Android `https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#S:kotlin.Int`, apps targeting API level `https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#S:kotlin.Int` or higher won't be able to start activities while processing broadcast receivers or services in response to notification action clicks. To launch an activity in those cases, provide a `https://developer.android.com/reference/kotlin/android/app/PendingIntent` to the activity itself.
As of Android `https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#N:kotlin.Int`, action button icons will not be displayed on action buttons, but are still required and are available to `https://developer.android.com/reference/kotlin/android/service/notification/NotificationListenerService.html#`, which may display them in other contexts, for example on a wearable device.
| Parameters ||
|---|---|
| `icon` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html): resource ID of a drawable that represents the action |
| `title` | [CharSequence](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-char-sequence/index.html)!: text describing the action |
| `intent` | [PendingIntent](https://developer.android.com/reference/kotlin/android/app/PendingIntent)!: PendingIntent to be fired when the action is invoked |

Added in [API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
open fun addPerson(person: Person!): Notification.Builder
```
Add a person that is relevant to this notification.
Depending on user preferences, this annotation may allow the notification to pass through interruption filters, if this notification is of category `https://developer.android.com/reference/kotlin/android/app/Notification#CATEGORY_CALL:kotlin.String` or `https://developer.android.com/reference/kotlin/android/app/Notification#CATEGORY_MESSAGE:kotlin.String`. The addition of people may also cause this notification to appear more prominently in the user interface.
A person should usually contain a uri in order to benefit from the ranking boost. However, even if no uri is provided, it's beneficial to provide other people in the notification, such that listeners and voice only devices can announce and handle them properly.
| Parameters ||
|---|---|
| `person` | [Person](https://developer.android.com/reference/kotlin/android/app/Person)!: the person to add |
| Return ||
|---|---|
| `https://developer.android.com/reference/kotlin/android/app/Notification.Builder#` | This value cannot be `null`. |

```
**Deprecated:** *use `https://developer.android.com/reference/kotlin/android/app/Notification.Builder#addPerson(android.app.Person)`*
Add a person that is relevant to this notification.
Depending on user preferences, this annotation may allow the notification to pass through interruption filters, if this notification is of category `https://developer.android.com/reference/kotlin/android/app/Notification#CATEGORY_CALL:kotlin.String` or `https://developer.android.com/reference/kotlin/android/app/Notification#CATEGORY_MESSAGE:kotlin.String`. The addition of people may also cause this notification to appear more prominently in the user interface.
The person should be specified by the `String` representation of a `https://developer.android.com/reference/kotlin/android/provider/ContactsContract.Contacts.html#CONTENT_LOOKUP_URI:android.net.Uri`.
The system will also attempt to resolve `mailto:` and `tel:` schema URIs. The path part of these URIs must exist in the contacts database, in the appropriate column, or the reference will be discarded as invalid. Telephone schema URIs will be resolved by `https://developer.android.com/reference/kotlin/android/provider/ContactsContract.PhoneLookup.html#`. It is also possible to provide a URI with the schema `name:` in order to uniquely identify a person without an entry in the contacts database.
| Parameters ||
|---|---|
| `uri` | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)!: a URI for the person |

### setFullScreenIntent
Added in [API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
open fun setFullScreenIntent(
intent: PendingIntent!,
highPriority: Boolean
): Notification.Builder
```
An intent to launch instead of posting the notification to the status bar. Only for use with extremely high-priority notifications demanding the user's **immediate** attention, such as an incoming phone call or alarm clock that the user has explicitly set to a particular time. If this facility is used for something else, please give the user an option to turn it off and use a normal notification, as this can be extremely disruptive.
Apps targeting `https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#Q:kotlin.Int` and above will have to request a permission (`https://developer.android.com/reference/kotlin/android/Manifest.permission.html#USE_FULL_SCREEN_INTENT:kotlin.String`) in order to use full screen intents.
Prior to `https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#TIRAMISU:kotlin.Int`, the system may display a heads up notification (which may display on screen longer than other heads up notifications), instead of launching the intent, while the user is using the device. From `https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#TIRAMISU:kotlin.Int`, the system UI will display a heads up notification, instead of launching this intent, while the user is using the device. This notification will display with emphasized action buttons. If the posting app holds `https://developer.android.com/reference/kotlin/android/Manifest.permission.html#USE_FULL_SCREEN_INTENT:kotlin.String`, then the heads up notification will appear persistently until the user dismisses or snoozes it, or the app cancels it. If the posting app does not hold `https://developer.android.com/reference/kotlin/android/Manifest.permission.html#USE_FULL_SCREEN_INTENT:kotlin.String`, then the notification will appear as heads up notification even when the screen is locked or turned off, and this notification will only be persistent for 60 seconds.
To be launched as a full screen intent, the notification must also be posted to a channel with importance level set to IMPORTANCE_HIGH or higher.
.
Requires `https://developer.android.com/reference/kotlin/android/Manifest.permission.html#USE_FULL_SCREEN_INTENT:kotlin.String`
| Parameters ||
|---|---|
| `intent` | [PendingIntent](https://developer.android.com/reference/kotlin/android/app/PendingIntent)!: the pending intent to launch |
| `highPriority` | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html): Passing `true` will cause this notification to be sent even if other notifications are suppressed |
| Return ||
|---|---|
| `https://developer.android.com/reference/kotlin/android/app/Notification.Builder#` | This value cannot be `null`. |

### setShortCriticalText
Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
open fun setShortCriticalText(shortCriticalText: String?): Notification.Builder
```
Sets a very short string summarizing the most critical information contained in the notification. Suggested max length is 7 characters, and there is no guarantee how much or how little of this text will be shown.
This field is designed exclusively for the compact representation (hereafter "chip") shown when the notification is `https://developer.android.com/reference/kotlin/android/app/Notification#FLAG_PROMOTED_ONGOING:kotlin.Int`.
- A chip's content may not be shown in certain states or if it cannot fit.
- Short critical text will always be the highest precedence content for a chip.
- Setting this to `""` will ensure the chip has no content; `null` (the default) will fall back to the other options.
- A `https://developer.android.com/reference/kotlin/android/app/Notification.MetricStyle`'s critical metric is the next option for the chip's content.
- A time (from `https://developer.android.com/reference/kotlin/android/app/Notification#when:kotlin.Long`) is the final source of content for the chip.
- If `https://developer.android.com/reference/kotlin/android/app/Notification.Builder#setUsesChronometer(kotlin.Boolean)` is `true`, the chip content will be a chronometer, if that is positive (based on `https://developer.android.com/reference/kotlin/android/app/Notification.Builder#setChronometerCountDown(kotlin.Boolean)`).
- If `https://developer.android.com/reference/kotlin/android/app/Notification.Builder#setShowWhen(kotlin.Boolean)` is true, the chip content will be the time remaining until `https://developer.android.com/reference/kotlin/android/app/Notification#when:kotlin.Long`, if positive.
| Parameters ||
|---|---|
| `shortCriticalText` | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)?: This value may be `null`. |
### setShortcutId
Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
open fun setShortcutId(shortcutId: String!): Notification.Builder
```
From Android 11, messaging notifications (those that use `https://developer.android.com/reference/kotlin/android/app/Notification.MessagingStyle`) that use this method to link to a published long-lived sharing shortcut may appear in a dedicated Conversation section of the shade and may show configuration options that are unique to conversations. This behavior should be reserved for person to person(s) conversations where there is a likely social obligation for an individual to respond.
For example, the following are some examples of notifications that belong in the conversation space:
- 1:1 conversations between two individuals
- Group conversations between individuals where everyone can contribute
And the following are some examples of notifications that do not belong in the conversation space:
- Advertisements from a bot (even if personal and contextualized)
- Engagement notifications from a bot
- Directional conversations where there is an active speaker and many passive individuals
- Stream / posting updates from other individuals
- Email, document comments, or other conversation types that are not real-time
Additionally, this method can be used for all types of notifications to mark this notification as duplicative of a Launcher shortcut. Launchers that show badges or notification content may then suppress the shortcut in favor of the content of this notification.
If this notification has `https://developer.android.com/reference/kotlin/android/app/Notification.BubbleMetadata` attached that was created with a shortcutId a check will be performed to ensure the shortcutId supplied to bubble metadata matches the shortcutId set here, if one was set. If the shortcutId's were specified but do not match, an exception is thrown.
| Parameters ||
|---|---|
| `shortcutId` | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)!: the `https://developer.android.com/reference/kotlin/android/content/pm/ShortcutInfo.html#getId()` of the shortcut this notification is linked to |
| Return ||

### setSubText
Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
open fun setSubText(text: CharSequence!): Notification.Builder
```
This provides some additional information that is displayed in the notification. No guarantees are given where exactly it is displayed.
This information should only be provided if it provides an essential benefit to the understanding of the notification. The more text you provide the less readable it becomes. For example, an email client should only provide the account name here if more than one email account has been added.
As of `https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#N:kotlin.Int` this information is displayed in the notification header area.
On Android versions before `https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#N:kotlin.Int` this will be shown in the third line of text in the platform notification template. You should not be using `https://developer.android.com/reference/kotlin/android/app/Notification.Builder#setProgress(kotlin.Int,%20kotlin.Int,%20kotlin.Boolean)` at the same time on those versions; they occupy the same place.
| Return ||
