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.RecentTaskInfo>`	`CREATOR`
`public int`	`affiliatedTaskId` This field was deprecated in API level 29. As of `Build.VERSION_CODES.Q`, currently always 0.
`public CharSequence`	`description` This field was deprecated in API level 29. As of `Build.VERSION_CODES.Q`, currently always null.
`public int`	`id` This field was deprecated in API level 29. As of `Build.VERSION_CODES.Q`, use `RecentTaskInfo.taskId` to get the task id and `RecentTaskInfo.isRunning` to determine if it is running.
`public int`	`persistentId` This field was deprecated in API level 29. As of `Build.VERSION_CODES.Q`, use `RecentTaskInfo.taskId`.

Inherited fields

From class android.app.TaskInfo

`public int`	`taskId` The identifier for this task.
`public ComponentName`	`topActivity` The component of the top activity in the task, currently showing to the user.

Fields

CREATOR

Added in API level 1

public static final Creator<ActivityManager.RecentTaskInfo> CREATOR

affiliatedTaskId

Added in API level 21
Deprecated in API level 29

public int affiliatedTaskId

This field was deprecated in API level 29.
As of Build.VERSION_CODES.Q, currently always 0.

Task affiliation for grouping with other tasks.

This field was deprecated in API level 29.
As of 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

public int id

This field was deprecated in API level 29.
As of 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

public int persistentId

This field was deprecated in API level 29.
As of Build.VERSION_CODES.Q, use RecentTaskInfo.taskId.

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

Public constructors

RecentTaskInfo

Added in API level 1

public RecentTaskInfo ()

Public methods

describeContents

Added in API level 1

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`

readFromParcel

Added in API level 1

public void readFromParcel (Parcel source)

Parameters
`source`	`Parcel`

writeToParcel

Added in API level 1

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. This value cannot be `null`.
`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
