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.

From class TaskInfo

`ComponentName?`	`baseActivity` The component of the first activity in the task, can be considered the "application" of this task.

`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.

writeToParcel

Added in API level 1

    dest: Parcel, 
    flags: Int
): Unit

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 `android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES

Properties

CREATOR
