RecentTaskInfo

Kotlin |Java

open class RecentTaskInfo : TaskInfo, Parcelable

kotlin.Any
↳	android.app.TaskInfo
	↳	android.app.ActivityManager.RecentTaskInfo

Information you can retrieve about tasks that the user has most recently started or visited.

Summary

Inherited constants

From class 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: 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)". Some implementations may want to release resources at this point.

Public constructors
`RecentTaskInfo()`

Public methods
open Int	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
open Unit	`readFromParcel(source: Parcel!)`
open Unit	`writeToParcel(dest: Parcel, flags: Int)` Flatten this object in to a Parcel.

Inherited functions

From class TaskInfo

Boolean

isVisible()

Whether this task is visible.

String

toString()

Returns a string representation of the object.

Properties
static Parcelable.Creator<ActivityManager.RecentTaskInfo!>	`CREATOR`
Int	`affiliatedTaskId` Task affiliation for grouping with other tasks.
CharSequence!	`description` Description of the task's last state.
Int	`id` If this task is currently running, this is the identifier for it.
Int	`persistentId` The true identifier of this task, valid even if it is not running.

Inherited properties

From class TaskInfo

`ComponentName?`	`baseActivity` The component of the first activity in the task, can be considered the "application" of this task.
`Intent`	`baseIntent` The base intent of the task (generally the intent that launched the task). This intent can be used to relaunch the task (if it is no longer running) or brought to the front if it is.
`Boolean`	`isRunning` Whether or not this task has any running activities.
`Int`	`numActivities` The number of activities in this task (including running).
`ComponentName?`	`origActivity` The component of the target activity if this task was started from an activity alias. Otherwise, this is null.
`ActivityManager.TaskDescription?`	`taskDescription` The recent activity values for the highest activity in the stack to have set the values. `Activity.setTaskDescription(android.app.ActivityManager.TaskDescription)`.
`Int`	`taskId` The identifier for this task.
`ComponentName?`	`topActivity` The component of the top activity in the task, currently showing to the user.

Public constructors

RecentTaskInfo

Added in API level 1

RecentTaskInfo()

Public methods

describeContents

Added in API level 1

open fun describeContents(): Int

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.

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

readFromParcel

Added in API level 1

open fun readFromParcel(source: Parcel!): Unit

writeToParcel

Added in API level 1

open fun writeToParcel(
    dest: Parcel, 
    flags: Int
): Unit

Flatten this object in to a Parcel.

Parameters
`dest`	Parcel: The Parcel in which the object should be written. This value cannot be `null`.
`flags`	Int: Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: `PARCELABLE_WRITE_RETURN_VALUE`

Properties

CREATOR

Added in API level 1

static val CREATOR: Parcelable.Creator<ActivityManager.RecentTaskInfo!>

affiliatedTaskId

Added in API level 21
Deprecated in API level 29

var affiliatedTaskId: Int

Deprecated: As of android.os.Build.VERSION_CODES#Q, currently always 0.

Task affiliation for grouping with other tasks.

description

Added in API level 11
Deprecated in API level 29

var description: CharSequence!

Deprecated: As of android.os.Build.VERSION_CODES#Q, currently always null.

Description of the task's last state.

id

Added in API level 1
Deprecated in API level 29

var id: Int

Deprecated: As of android.os.Build.VERSION_CODES#Q, use RecentTaskInfo.taskId to get the task id and RecentTaskInfo.isRunning to determine if it is running.

If this task is currently running, this is the identifier for it. If it is not running, this will be -1.

persistentId

Added in API level 12
Deprecated in API level 29

var persistentId: Int

Deprecated: As of android.os.Build.VERSION_CODES#Q, use RecentTaskInfo.taskId.

The true identifier of this task, valid even if it is not running.
