Constants

DEFAULT_CHANNEL_ID

Added in API level 26
public static final String DEFAULT_CHANNEL_ID

The id of the default channel for an app. This id is reserved by the system. All notifications posted from apps targeting Build.VERSION_CODES.N_MR1 or earlier without a notification channel specified are posted to this channel.

Constant Value: “miscellaneous”

Fields

CREATOR

Added in API level 26
public static final Creator<NotificationChannel> CREATOR

Public constructors

NotificationChannel

Added in API level 26
public NotificationChannel (String id, 
                CharSequence name, 
                int importance)

Creates a notification channel.

Parameters
id String: The id of the channel. Must be unique per package. The value may be truncated if it is too long.
name CharSequence: The user visible name of the channel. You can rename this channel when the system locale changes by listening for the Intent#ACTION_LOCALE_CHANGED broadcast. The recommended maximum length is 40 characters; the value may be truncated if it is too long.
importance int: The importance of the channel. This controls how interruptive notifications posted to this channel are. Value is NotificationManager.IMPORTANCE_UNSPECIFIEDNotificationManager.IMPORTANCE_NONENotificationManager.IMPORTANCE_MINNotificationManager.IMPORTANCE_LOWNotificationManager.IMPORTANCE_DEFAULT, or NotificationManager.IMPORTANCE_HIGH

Public methods

canBypassDnd

Added in API level 26
public boolean canBypassDnd ()

Whether or not notifications posted to this channel can bypass the Do Not DisturbNotificationManager#INTERRUPTION_FILTER_PRIORITY mode.

Returns
boolean

canShowBadge

Added in API level 26
public boolean canShowBadge ()

Returns whether notifications posted to this channel can appear as badges in a Launcher application. Note that badging may be disabled for other reasons.

Returns
boolean

describeContents

Added in API level 26
public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance’s marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

enableLights

Added in API level 26
public void enableLights (boolean lights)

Sets whether notifications posted to this channel should display notification lights, on devices that support that feature. Only modifiable before the channel is submitted toNotificationManager#createNotificationChannel(NotificationChannel).

Parameters
lights boolean

enableVibration

Added in API level 26
public void enableVibration (boolean vibration)

Sets whether notification posted to this channel should vibrate. The vibration pattern can be set with setVibrationPattern(long[]). Only modifiable before the channel is submitted toNotificationManager#createNotificationChannel(NotificationChannel).

Parameters
vibration boolean

equals

Added in API level 26
public boolean equals (Object o)

Indicates whether some other object is “equal to” this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value xx.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and yx.equals(y) should return true if and only ify.equals(x) returns true.
  • It is transitive: for any non-null reference values xy, and z, if x.equals(y) returns true and y.equals(z)returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value xx.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
o Object: the reference object with which to compare.
Returns
boolean true if this object is the same as the obj argument; false otherwise.

getAudioAttributes

Added in API level 26
public AudioAttributes getAudioAttributes ()

Returns
String

getImportance

Added in API level 26
public int getImportance ()

Returns the user specified importance e.g. NotificationManager#IMPORTANCE_LOW for notifications posted to this channel. Note: This value might be > NotificationManager#IMPORTANCE_NONE, but notifications posted to this channel will not be shown to the user if the parent NotificationChannelGroup or app is blocked. See NotificationChannelGroup#isBlocked() and NotificationManager#areNotificationsEnabled().

Returns
int

Returns

See also:

hashCode

Added in API level 26
public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
int a hash code value for this object.

setBypassDnd

Added in API level 26
public void setBypassDnd (boolean bypassDnd)

Parameters
lockscreenVisibility int

setName

Added in API level 26

setSound

Added in API level 26
public void setSound (Uri sound, 
                AudioAttributes audioAttributes)

Sets the sound that should be played for notifications posted to this channel and its audio attributes. Notification channels with an importance of at least NotificationManager#IMPORTANCE_DEFAULT should have a sound. Only modifiable before the channel is submitted toNotificationManager#createNotificationChannel(NotificationChannel).

Parameters
sound Uri
audioAttributes AudioAttributes

setVibrationPattern

Added in API level 26

toString

Added in API level 26
public String toString ()

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@‘, and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
Returns
String a string representation of the object.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
