Summary

Inherited constants

From interface android.os.Parcelable

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int`	`PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

Fields
`public static final Creator<ActivityManager.TaskDescription>`	`CREATOR`

Public constructors
`ActivityManager.TaskDescription(String label, int iconRes, int colorPrimary)` Creates the TaskDescription to the specified values.

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`Bitmap`	`getIcon()` This method was deprecated in API level R. This call is no longer supported. The caller should keep track of any icons it sets for the task descriptions internally.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public constructors

ActivityManager.TaskDescription

Added in API level 28

public ActivityManager.TaskDescription (String label, 
                int iconRes, 
                int colorPrimary)

Creates the TaskDescription to the specified values.

Parameters
`label`	`String`: A label and description of the current state of this task.
`iconRes`	`int`: A drawable resource of an icon that represents the current state of this activity.
`colorPrimary`	`int`: A color to override the theme's primary color. This color must be opaque.

ActivityManager.TaskDescription

Added in API level 28

                int iconRes)

Creates the TaskDescription to the specified values.

Parameters
`label`	`String`: A label and description of the current state of this activity.
`iconRes`	`int`: A drawable resource of an icon that represents the current state of this activity.

ActivityManager.TaskDescription

Added in API level 21

public ActivityManager.TaskDescription (String label)

Creates the TaskDescription to the specified values.

Parameters
`label`	`String`: A label and description of the current state of this activity.

ActivityManager.TaskDescription

Added in API level 21

public ActivityManager.TaskDescription ()

Creates an empty TaskDescription.

ActivityManager.TaskDescription

Added in API level 21

public ActivityManager.TaskDescription (String label, 
                Bitmap icon, 
                int colorPrimary)

This constructor is deprecated.
use TaskDescription constructor with icon resource instead

Creates the TaskDescription to the specified values.

Parameters
`label`	`String`: A label and description of the current state of this task.
`icon`	`Bitmap`: An icon that represents the current state of this task.
`colorPrimary`	`int`: A color to override the theme's primary color. This color must be opaque.

ActivityManager.TaskDescription

Added in API level 21

public ActivityManager.TaskDescription (String label, 
                Bitmap icon)

This constructor is deprecated.
use TaskDescription constructor with icon resource instead

Creates the TaskDescription to the specified values.

Parameters
`label`	`String`: A label and description of the current state of this activity.
`icon`	`Bitmap`: An icon that represents the current state of this activity.

ActivityManager.TaskDescription

Added in API level 21

public ActivityManager.TaskDescription (ActivityManager.TaskDescription td)

Creates a copy of another TaskDescription.

Parameters
`td`	`ActivityManager.TaskDescription`

Public methods

describeContents

Added in API level 21

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`

getIcon

Added in API level 21
Deprecated in API level R

public Bitmap getIcon ()

This method was deprecated in API level R.
This call is no longer supported. The caller should keep track of any icons it sets for the task descriptions internally.

Returns
`Bitmap`	The in-memory or loaded icon that represents the current state of this task.

getLabel

Added in API level 21

public String getLabel ()

Returns
`String`	The label and description of the current state of this task.

getPrimaryColor

Added in API level 21

public int getPrimaryColor ()

Returns
`int`	The color override on the theme's primary color.

readFromParcel

Added in API level 21

public void readFromParcel (Parcel source)

Parameters
`source`	`Parcel`

toString

Added in API level 21

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

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.

writeToParcel

Added in API level 21

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: The Parcel in which the object should be written.
`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
