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 is deprecated. As of `Build.VERSION_CODES.Q`, currently always 0.
`public CharSequence`	`description` This field is deprecated. As of `Build.VERSION_CODES.Q`, currently always null.
`public int`	`id` This field is deprecated. 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 is deprecated. As of `Build.VERSION_CODES.Q`, use `RecentTaskInfo#taskId`.

Inherited fields

From class android.app.TaskInfo

`public ComponentName`	`baseActivity` The component of the first activity in the task, can be considered the "application" of this task.
`public Intent`	`baseIntent` The base intent of the task (generally the intent that launched the task).
`public boolean`	`isRunning` Whether or not this task has any running activities.
`public int`	`numActivities` The number of activities in this task (including running).
`public ComponentName`	`origActivity` The component of the target activity if this task was started from an activity alias.
`public ActivityManager.TaskDescription`	`taskDescription` The recent activity values for the highest activity in the stack to have set the values.
`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.

          android.app.TaskInfo


      toString()

Returns a string representation of the object.

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.

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Fields

CREATOR

public static final Creator<ActivityManager.RecentTaskInfo> CREATOR

affiliatedTaskId

public int affiliatedTaskId

This field is deprecated.
As of Build.VERSION_CODES.Q, currently always 0.

Task affiliation for grouping with other tasks.

description

public CharSequence description

This field is deprecated.
As of Build.VERSION_CODES.Q, currently always null.

Description of the task's last state.

id

public int id

This field is deprecated.
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

public int persistentId

This field is deprecated.
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

public RecentTaskInfo ()

Public methods

describeContents

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

public void readFromParcel (Parcel source)

Parameters
`source`	`Parcel`

writeToParcel

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
