AccessibilityWindowInfo

public final class AccessibilityWindowInfo
extends Object implements Parcelable

java.lang.Object
↳	android.view.accessibility.AccessibilityWindowInfo

This class represents a state snapshot of a window for accessibility purposes. The screen content contains one or more windows where some windows can be descendants of other windows, which is the windows are hierarchically ordered. Note that there is no root window. Hence, the screen content can be seen as a collection of window trees.

Summary

Constants
`int`	`TYPE_ACCESSIBILITY_OVERLAY` Window type: Windows that are overlaid only by an `AccessibilityService` for interception of user interactions without changing the windows an accessibility service can introspect.
`int`	`TYPE_APPLICATION` Window type: This is an application window.
`int`	`TYPE_INPUT_METHOD` Window type: This is an input method window.
`int`	`TYPE_MAGNIFICATION_OVERLAY` Window type: A system window used to show the UI for the interaction with window-based magnification, which includes the magnified content and the option menu.
`int`	`TYPE_SPLIT_SCREEN_DIVIDER` Window type: A system window used to divide the screen in split-screen mode.
`int`	`TYPE_SYSTEM` Window type: This is a system window.
`int`	`TYPE_WINDOW_CONTROL` Window type: A system window that has the function to control an associated window.

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.

Constants

TYPE_ACCESSIBILITY_OVERLAY

Added in API level 22

 public static final int TYPE_ACCESSIBILITY_OVERLAY

Window type: Windows that are overlaid only by an AccessibilityService for interception of user interactions without changing the windows an accessibility service can introspect. In particular, an accessibility service can introspect only windows that a sighted user can interact with which they can touch these windows or can type into these windows. For example, if there is a full screen accessibility overlay that is touchable, the windows below it will be introspectable by an accessibility service regardless they are covered by a touchable window.

Constant Value: 4 (0x00000004)

Parameters
`parcel`	`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
