NotificationCompat.Builder

Constructor. Automatically sets the when field to System.currentTimeMillis() and the audio stream to the STREAM_DEFAULT.

Add an action to this notification. Actions are typically displayed by the system as a button adjacent to the notification content.
Action buttons won't appear on platforms prior to Android 4.1. Action buttons depend on expanded notifications, which are only available in Android 4.1 and later. To ensure that an action button's functionality is always available, first implement the functionality in the Activity that starts when a user clicks the notification (see setContentIntent()), and then enhance the notification by implementing the same functionality with addAction().

Merge additional metadata into this notification.

Values within the Bundle will replace existing extras values in this Builder.

Add a person that is relevant to this notification.

Combine all of the options that have been set and return a new Notification object.

Apply an extender to this notification builder. Extenders may be used to add metadata or change options on this builder.

Get the current metadata Bundle used by this notification Builder.

The returned Bundle is shared with this Builder.

The current contents of this Bundle are copied into the Notification each time build() is called.

Setting this flag will make it so the notification is automatically canceled when the user clicks it in the panel. The PendingIntent set with setDeleteIntent(PendingIntent) will be broadcast when the notification is canceled.

Set the notification category.

Must be one of the predefined notification categories (see the CATEGORY_* constants in Notification) that best describes this notification. May be used by the system for ranking and filtering.

Sets color.

Supply a custom RemoteViews to use instead of the standard one.

Set the large text at the right-hand side of the notification.

Supply a PendingIntent to send when the notification is clicked. If you do not supply an intent, you can now add PendingIntents to individual views to be launched when clicked by calling RemoteViews.setOnClickPendingIntent(int,PendingIntent). Be sure to read Notification.contentIntent for how to correctly use this.

Set the text (second row) of the notification, in a standard notification.

Set the title (first row) of the notification, in a standard notification.

Set the default notification options that will be used.

The value should be one or more of the following fields combined with bitwise-or: DEFAULT_SOUND, DEFAULT_VIBRATE, DEFAULT_LIGHTS.

For all default values, use DEFAULT_ALL.

Supply a PendingIntent to send when the notification is cleared by the user directly from the notification panel. For example, this intent is sent when the user clicks the "Clear all" button, or the individual "X" buttons on notifications. This intent is not sent when the application calls NotificationManager.cancel(int).

Set metadata for this notification.

A reference to the Bundle is held for the lifetime of this Builder, and the Bundle's current contents are copied into the Notification each time build() is called.

Replaces any existing extras values with those from the provided Bundle. Use addExtras(Bundle) to merge in metadata instead.

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.

Set this notification to be part of a group of notifications sharing the same key. Grouped notifications may display in a cluster or stack on devices which support such rendering.

To make this notification the summary for its group, also call setGroupSummary(boolean). A sort order can be specified for group members by using setSortKey(String).

Set this notification to be the group summary for a group of notifications. Grouped notifications may display in a cluster or stack on devices which support such rendering. Requires a group key also be set using setGroup(String).

Set the large icon that is shown in the ticker and notification.

Set the argb value that you would like the LED on the device to blnk, as well as the rate. The rate is specified in terms of the number of milliseconds to be on and then the number of milliseconds to be off.

Set whether or not this notification is only relevant to the current device.

Some notifications can be bridged to other devices for remote display. This hint can be set to recommend this notification not be bridged.

Set the large number at the right-hand side of the notification. This is equivalent to setContentInfo, although it might show the number in a different font size for readability.

Set whether this is an ongoing notification.

Ongoing notifications differ from regular notifications in the following ways:

• Ongoing notifications are sorted above the regular notifications in the notification panel.
• Ongoing notifications do not have an 'X' close button, and are not affected by the "Clear all" button.

Set this flag if you would only like the sound, vibrate and ticker to be played if the notification is not already showing.

Set the relative priority for this notification. Priority is an indication of how much of the user's valuable attention should be consumed by this notification. Low-priority notifications may be hidden from the user in certain situations, while the user might be interrupted for a higher-priority notification. The system sets a notification's priority based on various factors including the setPriority value. The effect may differ slightly on different platforms.

Set the progress this notification represents, which may be represented as a ProgressBar.

Supply a replacement Notification whose contents should be shown in insecure contexts (i.e. atop the secure lockscreen). See visibility and VISIBILITY_PUBLIC.

A variant of setSmallIcon(int) that takes an additional level parameter for when the icon is a LevelListDrawable.

Set the small icon to use in the notification layouts. Different classes of devices may return different sizes. See the UX guidelines for more information on how to design these icons.

Set a sort key that orders this notification among other notifications from the same package. This can be useful if an external sort was already applied and an app would like to preserve this. Notifications will be sorted lexicographically using this value, although providing different priorities in addition to providing sort key may cause this value to be ignored.

This sort key can also be used to order members of a notification group. See setGroup(String).

Set the sound to play. It will play on the default stream.

Set the sound to play. It will play on the stream you supply.

Add a rich notification style to be applied at build time.
If the platform does not provide rich notification styles, this method has no effect. The user will always see the normal notification style.

Set the third line of text in the platform notification template. Don't use if you're also using setProgress(int, int, boolean); they occupy the same location in the standard template.
If the platform does not provide large-format notifications, this method has no effect. The third line of text only appears in expanded view.

Set the text that is displayed in the status bar when the notification first arrives, and also a RemoteViews object that may be displayed instead on some devices.

Set the text that is displayed in the status bar when the notification first arrives.

Show the when field as a stopwatch. Instead of presenting when as a timestamp, the notification will show an automatically updating display of the minutes and seconds since when. Useful when showing an elapsed time (like an ongoing phone call).

Set the vibration pattern to use.

Sets visibility.

Set the time that the event occurred. Notifications in the panel are sorted by this time.
