### FLAG_INCLUDE_NOT_IMPORTANT_VIEWS
Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final int FLAG_INCLUDE_NOT_IMPORTANT_VIEWS
```
If this flag is set the system will regard views that are not important
for accessibility in addition to the ones that are important for accessibility.
That is, views that are marked as not important for accessibility via
`https://developer.android.com/reference/android/view/View#IMPORTANT_FOR_ACCESSIBILITY_NO` or
`https://developer.android.com/reference/android/view/View#IMPORTANT_FOR_ACCESSIBILITY_NO_HIDE_DESCENDANTS` and views that are
marked as potentially important for accessibility via
`https://developer.android.com/reference/android/view/View#IMPORTANT_FOR_ACCESSIBILITY_AUTO` for which the system has determined
that are not important for accessibility, are reported while querying the window
content and also the accessibility service will receive accessibility events from
them.
**Note:** For accessibility services targeting Android 4.1 (API level 16) or
higher, this flag has to be explicitly set for the system to regard views that are not
important for accessibility. For accessibility services targeting Android 4.0.4 (API level
15) or lower, this flag is ignored and all views are regarded for accessibility purposes.
Usually views not important for accessibility are layout managers that do not
react to user actions, do not draw any content, and do not have any special
semantics in the context of the screen content. For example, a three by three
grid can be implemented as three horizontal linear layouts and one vertical,
or three vertical linear layouts and one horizontal, or one grid layout, etc.
In this context, the actual layout managers used to achieve the grid configuration
are not important; rather it is important that there are nine evenly distributed
elements.

public static final int FLAG_REQUEST_FILTER_KEY_EVENTS
```
This flag requests from the system to filter key events. If this flag
is set the accessibility service will receive the key events before
applications allowing it implement global shortcuts.
Services that want to set this flag have to declare this capability
in their meta-data by setting the attribute `https://developer.android.com/reference/android/R.attr` to true,
otherwise this flag will be ignored. For how to declare the meta-data
of a service refer to `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#SERVICE_META_DATA`.

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final int FLAG_REQUEST_MULTI_FINGER_GESTURES
```
This flag requests that when `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#FLAG_REQUEST_TOUCH_EXPLORATION_MODE` is enabled,
multi-finger gestures are also enabled. As a consequence, two-finger bypass gestures will be
disabled. If `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#FLAG_REQUEST_TOUCH_EXPLORATION_MODE` is disabled this flag has no
effect.
**See also:**

### FLAG_REQUEST_SHORTCUT_WARNING_DIALOG_SPOKEN_FEEDBACK
Added in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final int FLAG_REQUEST_SHORTCUT_WARNING_DIALOG_SPOKEN_FEEDBACK
```
This flag requests that accessibility shortcut warning dialog has spoken feedback when
dialog is shown.
Constant Value:

(0x00000400)
### FLAG_REQUEST_TOUCH_EXPLORATION_MODE
Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final int FLAG_REQUEST_TOUCH_EXPLORATION_MODE
```
This flag requests that the system gets into touch exploration mode.
In this mode a single finger moving on the screen behaves as a mouse
pointer hovering over the user interface. The system will also detect
certain gestures performed on the touch screen and notify this service.
The system will enable touch exploration mode if there is at least one
accessibility service that has this flag set. Hence, clearing this
flag does not guarantee that the device will not be in touch exploration
mode since there may be another enabled service that requested it.
For accessibility services targeting Android 4.3 (API level 18) or higher
that want to set this flag have to declare this capability in their
meta-data by setting the attribute
`https://developer.android.com/reference/android/R.attr#canRequestTouchExplorationMode` to true. Otherwise, this flag will
be ignored. For how to declare the meta-data of a service refer to
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#SERVICE_META_DATA`.
Services targeting Android 4.2.2 (API level 17) or lower will work
normally. In other words, the first time they are run, if this flag is
specified, a dialog is shown to the user to confirm enabling explore by
touch.

### FLAG_RETRIEVE_INTERACTIVE_WINDOWS
Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final int FLAG_RETRIEVE_INTERACTIVE_WINDOWS
```
This flag indicates to the system that the accessibility service wants
to access content of all interactive windows. An interactive window is a
window that has input focus or can be touched by a sighted user when explore
by touch is not enabled. If this flag is not set your service will not receive
`https://developer.android.com/reference/android/view/accessibility/AccessibilityEvent#TYPE_WINDOWS_CHANGED`
events, calling AccessibilityService`https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#getWindows()` will return an empty list, and `https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo#getWindow()` will
return null.
Services that want to set this flag have to declare the capability
to retrieve window content in their meta-data by setting the attribute
`https://developer.android.com/reference/android/R.attr#canRetrieveWindowContent` to
true, otherwise this flag will be ignored. For how to declare the meta-data
of a service refer to `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#SERVICE_META_DATA`.

### FLAG_SEND_MOTION_EVENTS
Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final int FLAG_SEND_MOTION_EVENTS
```
This flag requests that when `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#FLAG_REQUEST_TOUCH_EXPLORATION_MODE` is enabled, a
service will receive the motion events for each successfully-detected gesture. The service
will also receive an AccessibilityGestureEvent of type GESTURE_INVALID for each cancelled
gesture along with its motion events. A service will receive a gesture of type
GESTURE_PASSTHROUGH and accompanying motion events for every passthrough gesture that does
not start gesture detection. This information can be used to collect instances of improper
gesture detection behavior and relay that information to framework developers. If `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#FLAG_REQUEST_TOUCH_EXPLORATION_MODE` is disabled this flag has no effect.

### flags
Added in [API level 4](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public int flags
```
This field represents a set of flags used for configuring an
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityService`.
**Can be dynamically set at runtime.**
**Note:** Accessibility services with targetSdkVersion greater than
`https://developer.android.com/reference/android/os/Build.VERSION_CODES#Q` cannot dynamically set the
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#FLAG_REQUEST_ACCESSIBILITY_BUTTON` at runtime. It must be specified in the
accessibility service metadata file.

```
Creates a new instance.
## Public methods
### capabilityToString
Added in [API level 18](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static String capabilityToString (int capability)
```
Returns the string representation of a capability. For example,
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#CAPABILITY_CAN_RETRIEVE_WINDOW_CONTENT` is represented
by the string CAPABILITY_CAN_RETRIEVE_WINDOW_CONTENT.
| Parameters ||
|---|---|
| `capability` | `int`: The capability.
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | The string representation.
|
### describeContents
Added in [API level 4](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
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 `https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)`,
the return value of this method must include the
`https://developer.android.com/reference/android/os/Parcelable#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 - `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` |
### equals
Added in [API level 4](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public boolean equals (Object obj)
```
Indicates whether some other object is "equal to" this one.
The `equals` method implements an equivalence relation
on non-null object references:
- It is *reflexive*: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is *symmetric*: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is *transitive*: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is *consistent*: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.
An equivalence relation partitions the elements it operates on
into *equivalence classes*; all the members of an
equivalence class are equal to each other. Members of an
equivalence class are substitutable for each other, at least
for some purposes.
| Parameters ||
|---|---|
| `obj` | `Object`: This value may be `null`.
|
| Returns ||
|---|---|
| `boolean` | `true` if this object is the same as the obj argument; `false` otherwise.

### hashCode
Added in [API level 4](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public int hashCode ()
```
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
`https://developer.android.com/reference/java/util/HashMap`.
The general contract of `hashCode` is:
- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is *not* required that if two objects are unequal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
| Returns ||
|---|---|
| `int` | a hash code value for this object.
|

### setInteractiveUiTimeoutMillis
Added in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setInteractiveUiTimeoutMillis (int timeout)
```
Set the recommended time that interactive controls need to remain on the screen to
support the user.
**This value can be dynamically set at runtime by
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#setServiceInfo(android.accessibilityservice.AccessibilityServiceInfo)`.**
| Parameters ||
|---|---|
| `timeout` | `int`: The timeout in milliseconds. Value is 0 or greater
|
**See also:**

### setMotionEventSources
Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public void setMotionEventSources (int motionEventSources)
```
Sets the bit mask of `https://developer.android.com/reference/android/view/InputDevice` sources that the accessibility
service wants to listen to for generic `https://developer.android.com/reference/android/view/MotionEvent`s.
Including an `https://developer.android.com/reference/android/view/InputDevice` source that does not send
`https://developer.android.com/reference/android/view/MotionEvent`s is effectively a no-op for that source, since you will
not receive any events from that source.
See `https://developer.android.com/reference/android/view/InputDevice` for complete source definitions.
Many input devices send `https://developer.android.com/reference/android/view/InputEvent`s from more than one type of source so
you may need to include multiple `https://developer.android.com/reference/android/view/MotionEvent` sources here, in addition
to using `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#onKeyEvent(android.view.KeyEvent)` to listen to `https://developer.android.com/reference/android/view/KeyEvent`s.
**Note:** `https://developer.android.com/reference/android/view/InputDevice` sources contain source class bits
that complicate bitwise flag removal operations. To remove a specific source you should
rebuild the entire value using bitwise OR operations on the individual source constants.
| Parameters ||
|---|---|
| `motionEventSources` | `int`: A bit mask of `https://developer.android.com/reference/android/view/InputDevice` sources. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_MOUSE` - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_STYLUS` - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_BLUETOOTH_STYLUS` - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_TRACKBALL` - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_MOUSE_RELATIVE` - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_TOUCHPAD` - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_TOUCH_NAVIGATION` - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_ROTARY_ENCODER` - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_JOYSTICK` - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_SENSOR` - `https://developer.android.com/reference/android/view/InputDevice#SOURCE_TOUCHSCREEN` |
