*** ** * ** ***

Accessibility services should only be used to assist users with disabilities in using
Android devices and apps. They run in the background and receive callbacks by the system
when `https://developer.android.com/reference/android/view/accessibility/AccessibilityEvent`s are fired. Such events denote some state transition
in the user interface, for example, the focus has changed, a button has been clicked,
etc. Such a service can optionally request the capability for querying the content
of the active window. Development of an accessibility service requires extending this
class and implementing its abstract methods.

### Developer Guides

For more information about creating AccessibilityServices, read the
[Accessibility](https://developer.android.com/guide/topics/ui/accessibility)
developer guide.

### Lifecycle


The lifecycle of an accessibility service is managed exclusively by the system and
follows the established service life cycle. Starting an accessibility service is triggered
exclusively by the user explicitly turning the service on in device settings. After the system
binds to a service, it calls `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#onServiceConnected()`. This method can
be overridden by clients that want to perform post binding setup.


An accessibility service stops either when the user turns it off in device settings or when
it calls `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#disableSelf()`.

### Declaration


An accessibility is declared as any other service in an AndroidManifest.xml, but it
must do two things:

- Specify that it handles the "android.accessibilityservice.AccessibilityService" `https://developer.android.com/reference/android/content/Intent`.
- Request the `https://developer.android.com/reference/android/Manifest.permission#BIND_ACCESSIBILITY_SERVICE` permission to ensure that only the system can bind to it.

If either of these items is missing, the system will ignore the accessibility service. Following is an example declaration:

<br />

```
 <service android:name=".MyAccessibilityService"
        android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
    <intent-filter>
        <action android:name="android.accessibilityservice.AccessibilityService" />
    </intent-filter>
    . . .
</service>
```

### Configuration


An accessibility service can be configured to receive specific types of accessibility events,
listen only to specific packages, get events from each type only once in a given time frame,
retrieve window content, specify a settings activity, etc.


There are two approaches for configuring an accessibility service:

- Providing a `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#SERVICE_META_DATA` entry in the manifest when declaring the service. A service declaration with a meta-data tag is presented below:

  ```
   <service android:name=".MyAccessibilityService">
      <intent-filter>
          <action android:name="android.accessibilityservice.AccessibilityService" />
      </intent-filter>
      <meta-data android:name="android.accessibilityservice" android:resource="@xml/accessibilityservice" />
  </service>
  ```


  **Note:** This approach enables setting all properties.


  For more details refer to `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#SERVICE_META_DATA` and
  ``<`https://developer.android.com/reference/android/R.styleable#AccessibilityService`>``.
- Calling `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#setServiceInfo(android.accessibilityservice.AccessibilityServiceInfo)`. Note that this method can be called any time to dynamically change the service configuration.


  **Note:** This approach enables setting only dynamically configurable properties:
  `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#eventTypes`,
  `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#feedbackType`,
  `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#flags`,
  `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#notificationTimeout`,
  `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#packageNames`


  For more details refer to `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo`.

### Retrieving window content


A service can specify in its declaration that it can retrieve window
content which is represented as a tree of `https://developer.android.com/reference/android/view/accessibility/AccessibilityWindowInfo` and
`https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo` objects. Note that
declaring this capability requires that the service declares its configuration via
an XML resource referenced by `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#SERVICE_META_DATA`.


Window content may be retrieved with
`https://developer.android.com/reference/android/view/accessibility/AccessibilityRecord#getSource()`,
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#findFocus(int)`,
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#getWindows()`, or
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#getRootInActiveWindow()`.


**Note** An accessibility service may have requested to be notified for
a subset of the event types, and thus be unaware when the node hierarchy has changed. It is also
possible for a node to contain outdated information because the window content may change at any
time.

### Drawing Accessibility Overlays

Accessibility services can draw overlays on top of existing screen contents.
Accessibility overlays can be used to visually highlight items on the screen
e.g. indicate the current item with accessibility focus.
Overlays can also offer the user a way to interact with the service directly and quickly
customize the service's behavior.

Accessibility overlays can be attached to a particular window or to the display itself.
Attaching an overlay to a window allows the overly to move, grow and shrink as the window does.
The overlay will maintain the same relative position within the window bounds as the window
moves. The overlay will also maintain the same relative position within the window bounds if
the window is resized.
To attach an overlay to a window, use `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#attachAccessibilityOverlayToWindow(int,%20android.view.SurfaceControl)`.
Attaching an overlay to the display means that the overlay is independent of the active
windows on that display.
To attach an overlay to a display, use `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#attachAccessibilityOverlayToDisplay(int,%20android.view.SurfaceControl)`.

When positioning an overlay that is attached to a window, the service must use window
coordinates. In order to position an overlay on top of an existing UI element it is necessary
to know the bounds of that element in window coordinates. To find the bounds in window
coordinates of an element, find the corresponding `https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo` as discussed
above and call `https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo#getBoundsInWindow(android.graphics.Rect)`.

### Notification strategy


All accessibility services are notified of all events they have requested, regardless of their
feedback type.


**Note:** The event notification timeout is useful to avoid propagating
events to the client too frequently since this is accomplished via an expensive
interprocess call. One can think of the timeout as a criteria to determine when
event generation has settled down.

```

<br />

<br />

## Public methods

### attachAccessibilityOverlayToDisplay

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void attachAccessibilityOverlayToDisplay (int displayId, 
                SurfaceControl sc)
```

Attaches a `https://developer.android.com/reference/android/view/SurfaceControl` containing an accessibility overlay to the
specified display. This type of overlay should be used for content that does not need to
track the location and size of Views in the currently active app e.g. service configuration
or general service UI.

Generally speaking, an accessibility overlay will be a `https://developer.android.com/reference/android/view/View`. To embed
the View into a `https://developer.android.com/reference/android/view/SurfaceControl`, create a `https://developer.android.com/reference/android/view/SurfaceControlViewHost` and attach the View using `https://developer.android.com/reference/android/view/SurfaceControlViewHost#setView(android.view.View,%20android.view.SurfaceControlViewHost.LayoutParams)`. Then obtain the SurfaceControl by calling
` viewHost.getSurfacePackage().getSurfaceControl()`.

To remove this overlay and free the associated resources, use `
new SurfaceControl.Transaction().reparent(sc, null).apply();`.

If the specified overlay has already been attached to the specified display this method
does nothing. If the specified overlay has already been attached to a previous display this
function will transfer the overlay to the new display. Services can attach multiple overlays.
Use ` new SurfaceControl.Transaction().setLayer(sc, layer).apply();`. to
coordinate the order of the overlays on screen.

<br />

| Parameters ||
|---|---|
| `displayId` | `int`: the display to which the SurfaceControl should be attached. <br /> |
| `sc` | `SurfaceControl`: the SurfaceControl containing the overlay content. This value cannot be `null`. <br /> |

### attachAccessibilityOverlayToWindow

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void attachAccessibilityOverlayToWindow (int accessibilityWindowId, 
                SurfaceControl sc)
```

Attaches an accessibility overlay `https://developer.android.com/reference/android/view/SurfaceControl` to the specified
window. This method should be used when you want the overlay to move and resize as the parent
window moves and resizes.

Generally speaking, an accessibility overlay will be a `https://developer.android.com/reference/android/view/View`. To embed
the View into a `https://developer.android.com/reference/android/view/SurfaceControl`, create a `https://developer.android.com/reference/android/view/SurfaceControlViewHost` and attach the View using `https://developer.android.com/reference/android/view/SurfaceControlViewHost#setView(android.view.View,%20android.view.SurfaceControlViewHost.LayoutParams)`. Then obtain the SurfaceControl by calling
` viewHost.getSurfacePackage().getSurfaceControl()`.

To remove this overlay and free the associated resources, use `
new SurfaceControl.Transaction().reparent(sc, null).apply();`.

If the specified overlay has already been attached to the specified window this method
does nothing. If the specified overlay has already been attached to a previous window this
function will transfer the overlay to the new window. Services can attach multiple overlays.
Use ` new SurfaceControl.Transaction().setLayer(sc, layer).apply();`. to
coordinate the order of the overlays on screen.

<br />

| Parameters ||
|---|---|
| `accessibilityWindowId` | `int`: The window id, from `https://developer.android.com/reference/android/view/accessibility/AccessibilityWindowInfo#getId()`. <br /> |
| `sc` | `SurfaceControl`: the SurfaceControl containing the overlay content. This value cannot be `null`. <br /> |

### clearCache

Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean clearCache ()
```

Clears the cache.

<br />

| Returns ||
|---|---|
| `boolean` | `true` if the cache was cleared <br /> |

### clearCachedSubtree

Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean clearCachedSubtree (AccessibilityNodeInfo node)
```

Invalidates `node` and its subtree in the cache.

<br />

| Parameters ||
|---|---|
| `node` | `AccessibilityNodeInfo`: the node to invalidate. This value cannot be `null`. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if the subtree rooted at `node` was invalidated. <br /> |

### createDisplayContext

Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Context createDisplayContext (Display display)
```

Returns a new `Context` object from the current context but with resources
adjusted to match the metrics of `display`. Each call to this method
returns a new instance of a context object. Context objects are not shared; however,
common state (such as the `https://developer.android.com/reference/java/lang/ClassLoader` and other resources for the same
configuration) can be shared, so the `Context` itself is lightweight.

**Note:**
This `Context` is **not** expected to be updated with new configuration if the
underlying display configuration changes and the cached `Resources` it returns
could be stale. It is suggested to use
`https://developer.android.com/reference/android/hardware/display/DisplayManager.DisplayListener` to listen for
changes and re-create an instance if necessary.


This `Context` is **not** a UI context, do not use it to access UI components
or obtain a `https://developer.android.com/reference/android/view/WindowManager` instance.


To obtain an instance of `https://developer.android.com/reference/android/view/WindowManager` configured to show windows on the given
display, call `https://developer.android.com/reference/android/content/Context#createWindowContext(int,%20android.os.Bundle)` on the returned display context,
then call `https://developer.android.com/reference/android/content/Context#getSystemService(java.lang.String)` or `https://developer.android.com/reference/android/content/Context#getSystemService(java.lang.Class<T>)` on the
returned window context.

<br />

<br />

| Parameters ||
|---|---|
| `display` | `Display`: The display to which the current context's resources are adjusted. This value cannot be `null`. <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/content/Context` | This value cannot be `null`. <br /> |

### createWindowContext

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Context createWindowContext (int type, 
                Bundle options)
```

Creates a Context for a non-activity window.


A window context is a context that can be used to add non-activity windows, such as
`https://developer.android.com/reference/android/view/WindowManager.LayoutParams#TYPE_APPLICATION_OVERLAY`. A window context
must be created from a context that has an associated `https://developer.android.com/reference/android/view/Display`, such as
`https://developer.android.com/reference/android/app/Activity` or a context created with
`https://developer.android.com/reference/android/content/Context#createDisplayContext(android.view.Display)`.


The window context is created with the appropriate `https://developer.android.com/reference/android/content/res/Configuration` for the area of the
display that the windows created with it can occupy; it must be used when
`https://developer.android.com/reference/android/view/LayoutInflater` views, such that they can be inflated with
proper `https://developer.android.com/reference/android/content/res/Resources`.

Below is a sample code to **add an application overlay window on the primary display:**

```
...
final DisplayManager dm = anyContext.getSystemService(DisplayManager.class);
final Display primaryDisplay = dm.getDisplay(DEFAULT_DISPLAY);
final Context windowContext = anyContext.createDisplayContext(primaryDisplay)
        .createWindowContext(TYPE_APPLICATION_OVERLAY, null);
final View overlayView = Inflater.from(windowContext).inflate(someLayoutXml, null);

// WindowManager.LayoutParams initialization
...
// The types used in addView and createWindowContext must match.
mParams.type = TYPE_APPLICATION_OVERLAY;
...

windowContext.getSystemService(WindowManager.class).addView(overlayView, mParams);
```


This context's configuration and resources are adjusted to an area of the display where
the windows with provided type will be added. **Note that all windows associated with the
same context will have an affinity and can only be moved together between different displays
or areas on a display.** If there is a need to add different window types, or
non-associated windows, separate Contexts should be used.


Creating a window context is an expensive operation. Misuse of this API may lead to a huge
performance drop. The best practice is to use the same window context when possible.
An approach is to create one window context with specific window type and display and
use it everywhere it's needed.


After `https://developer.android.com/reference/android/os/Build.VERSION_CODES#S`, window context provides the capability to receive
configuration changes for existing token by overriding the
`https://developer.android.com/reference/android/view/WindowManager.LayoutParams#token` of the
`https://developer.android.com/reference/android/view/WindowManager.LayoutParams` passed in
`https://developer.android.com/reference/android/view/ViewManager#addView(android.view.View,%20android.view.ViewGroup.LayoutParams)`. This is useful when an application needs
to attach its window to an existing activity for window token sharing use-case.


Note that the window context in `https://developer.android.com/reference/android/os/Build.VERSION_CODES#R` didn't have this
capability. This is a no-op for the window context in `https://developer.android.com/reference/android/os/Build.VERSION_CODES#R`.
Below is sample code to **attach an existing token to a window context:**

```
final DisplayManager dm = anyContext.getSystemService(DisplayManager.class);
final Display primaryDisplay = dm.getDisplay(DEFAULT_DISPLAY);
final Context windowContext = anyContext.createWindowContext(primaryDisplay,
        TYPE_APPLICATION, null);

// Get an existing token.
final IBinder existingToken = activity.getWindow().getAttributes().token;

// The types used in addView() and createWindowContext() must match.
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(TYPE_APPLICATION);
params.token = existingToken;

// After WindowManager#addView(), the server side will extract the provided token from
// LayoutParams#token (existingToken in the sample code), and switch to propagate
// configuration changes from the node associated with the provided token.
windowContext.getSystemService(WindowManager.class).addView(overlayView, mParams);
```


After `https://developer.android.com/reference/android/os/Build.VERSION_CODES#S`, window context provides the capability to listen to its
`https://developer.android.com/reference/android/content/res/Configuration` changes by calling
`https://developer.android.com/reference/android/content/Context#registerComponentCallbacks(android.content.ComponentCallbacks)`, while other kinds of `https://developer.android.com/reference/android/content/Context`
will register the `https://developer.android.com/reference/android/content/ComponentCallbacks` to `https://developer.android.com/reference/android/content/Context#getApplicationContext()`. Note that window context only propagate
`https://developer.android.com/reference/android/content/ComponentCallbacks#onConfigurationChanged(android.content.res.Configuration)` callback.
`https://developer.android.com/reference/android/content/ComponentCallbacks#onLowMemory()` or other callbacks in `https://developer.android.com/reference/android/content/ComponentCallbacks2`
won't be invoked.


Note that using `https://developer.android.com/reference/android/app/Application` or `https://developer.android.com/reference/android/app/Service` context for
UI-related queries may result in layout or continuity issues on devices with variable screen
sizes (e.g. foldables) or in multi-window modes, since these non-UI contexts may not reflect
the `https://developer.android.com/reference/android/content/res/Configuration` changes for the visual container.

<br />

### disableSelf

Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public final void disableSelf ()
```

Disables the service. After calling this method, the service will be disabled and settings
will show that it is turned off.

<br />

### dispatchGesture

Added in [API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public final boolean dispatchGesture (GestureDescription gesture, 
                AccessibilityService.GestureResultCallback callback, 
                Handler handler)
```

Dispatch a gesture to the touch screen. Any gestures currently in progress, whether from
the user, this service, or another service, will be cancelled.


The gesture will be dispatched as if it were performed directly on the screen by a user, so
the events may be affected by features such as magnification and explore by touch.


**Note:** In order to dispatch gestures, your service
must declare the capability by setting the
`https://developer.android.com/reference/android/R.styleable#AccessibilityService_canPerformGestures`
property in its meta-data. For more information, see
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#SERVICE_META_DATA`.

Since many apps do not appropriately support `https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo.AccessibilityAction#ACTION_CLICK`,
if this action fails on an element that should be clickable, a service that is not a screen
reader may send a tap directly to the element as a fallback. The example below
demonstrates this fallback using the gesture dispatch APIs:

         private void tap(PointF point) {
             StrokeDescription tap =  new StrokeDescription(path(point), 0,
             ViewConfiguration.getTapTimeout());
             GestureDescription.Builder builder = new GestureDescription.Builder();
             builder.addStroke(tap);
             dispatchGesture(builder.build(), null, null);
         }

     
<br />

<br />

| Parameters ||
|---|---|
| `gesture` | `GestureDescription`: The gesture to dispatch. This value cannot be `null`. <br /> |
| `callback` | `AccessibilityService.GestureResultCallback`: The object to call back when the status of the gesture is known. If `null`, no status is reported. <br /> |
| `handler` | `Handler`: The handler on which to call back the `callback` object. If `null`, the object is called back on the service's main thread. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if the gesture is dispatched, `false` if not. <br /> |

### findFocus

Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public AccessibilityNodeInfo findFocus (int focus)
```

Find the view that has the specified focus type. The search is performed
across all windows.


**Note:** In order to access the windows your service has
to declare the capability to retrieve window content by setting the
`https://developer.android.com/reference/android/R.styleable#AccessibilityService_canRetrieveWindowContent`
property in its meta-data. For details refer to `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#SERVICE_META_DATA`.
Also the service has to opt-in to retrieve the interactive windows by
setting the `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#FLAG_RETRIEVE_INTERACTIVE_WINDOWS`
flag. Otherwise, the search will be performed only in the active window.


**Note:** If the view with `https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo#FOCUS_INPUT`
is on an embedded view hierarchy which is embedded in a `https://developer.android.com/reference/android/view/SurfaceView` via
`https://developer.android.com/reference/android/view/SurfaceView#setChildSurfacePackage(android.view.SurfaceControlViewHost.SurfacePackage)`, there is a limitation that this API
won't be able to find the node for the view. It's because views don't know about
the embedded hierarchies. Instead, you could traverse all the nodes to find the
focus.

<br />

<br />

| Parameters ||
|---|---|
| `focus` | `int`: The focus to find. One of `https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo#FOCUS_INPUT` or `https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo#FOCUS_ACCESSIBILITY`. <br /> |

Note: System services obtained via this API may be closely associated with the Context in
which they are obtained from. In general, do not share the service objects between various
different contexts (Activities, Applications, Services, Providers, etc.)

Note: Instant apps, for which `https://developer.android.com/reference/android/content/pm/PackageManager#isInstantApp()` returns true, don't
have access to the following system services: `https://developer.android.com/reference/android/content/Context#DEVICE_POLICY_SERVICE`, `https://developer.android.com/`, `https://developer.android.com/reference/android/content/Context#KEYGUARD_SERVICE`, `https://developer.android.com/reference/android/content/Context#SHORTCUT_SERVICE`, `https://developer.android.com/reference/android/content/Context#USB_SERVICE`, `https://developer.android.com/reference/android/content/Context#WALLPAPER_SERVICE`, `https://developer.android.com/reference/android/content/Context#WIFI_P2P_SERVICE`, `https://developer.android.com/reference/android/content/Context#WIFI_SERVICE`,
`https://developer.android.com/reference/android/content/Context#WIFI_AWARE_SERVICE`. For these services this method will return `null`.
Generally, if you are running as an instant app you should always check whether the result of
this method is `null`.

Note: When implementing this method, keep in mind that new services can be added on newer
Android releases, so if you're looking for just the explicit names mentioned above, make sure
to return `null` when you don't recognize the name --- if you throw a `https://developer.android.com/reference/java/lang/RuntimeException` exception instead, your app might break on new Android releases.

Returns the touch interaction controller for the specified logical display, which may be used
to detect gestures and otherwise control touch interactions. If
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#FLAG_REQUEST_TOUCH_EXPLORATION_MODE` is disabled the
controller's methods will have no effect.

<br />

| Parameters ||
|---|---|
| `displayId` | `int`: The logical display id, use `https://developer.android.com/reference/android/view/Display#DEFAULT_DISPLAY` for default display. <br /> |

| Returns ||

### getWindows

Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public List<AccessibilityWindowInfo> getWindows ()
```

Gets the windows on the screen of the default display. This method returns only the windows
that a sighted user can interact with, as opposed to all windows.
For example, if there is a modal dialog shown and the user cannot touch
anything behind it, then only the modal window will be reported
(assuming it is the top one). For convenience the returned windows
are ordered in a descending layer order, which is the windows that
are on top are reported first. Since the user can always
interact with the window that has input focus by typing, the focused
window is always returned (even if covered by a modal window).


**Note:** In order to access the windows your service has
to declare the capability to retrieve window content by setting the
`https://developer.android.com/reference/android/R.styleable#AccessibilityService_canRetrieveWindowContent`
property in its meta-data. For details refer to `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#SERVICE_META_DATA`.
Also the service has to opt-in to retrieve the interactive windows by
setting the `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#FLAG_RETRIEVE_INTERACTIVE_WINDOWS`
flag.

<br />

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/util/List<https://developer.android.com/reference/android/view/accessibility/AccessibilityWindowInfo>` | The windows if there are windows and the service is can retrieve them, otherwise an empty list. <br /> |

### getWindowsOnAllDisplays

anything behind it, then only the modal window will be reported
(assuming it is the top one). For convenience the returned windows
are ordered in a descending layer order, which is the windows that
are on top are reported first. Since the user can always
interact with the window that has input focus by typing, the focused
window is always returned (even if covered by a modal window).

**Note:** To receive gestures an accessibility service must
request that the device is in touch exploration mode by setting the
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#FLAG_REQUEST_TOUCH_EXPLORATION_MODE`
flag.


**Note:** The default implementation calls `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#onGesture(int)` when the
touch screen is default display.

<br />

`https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#setMotionEventSources(int)`.
`https://developer.android.com/reference/android/view/MotionEvent`s from sources in `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#getMotionEventSources()`
are not sent to the rest of the system. To stop listening to events from a given source, call
`https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo#setMotionEventSources(int)` with that source removed.

<br />

<br />

| Parameters ||
|---|---|
| `event` | `MotionEvent`: The event to be processed. This value cannot be `null`. <br /> |

### onSystemActionsChanged

### setAccessibilityFocusAppearance

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void setAccessibilityFocusAppearance (int strokeWidth, 
                int color)
```

Sets the strokeWidth and color of the accessibility focus rectangle.


**Note:** This setting persists until this or another active
AccessibilityService changes it or the device reboots.

<br />

<br />

| Parameters ||
|---|---|
| `strokeWidth` | `int`: The stroke width of the rectangle in pixels. Setting this value to zero results in no focus rectangle being drawn. <br /> |
| `color` | `int`: The color of the rectangle. <br /> |

### setAnimationScale

Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void setAnimationScale (float scale)
```

Sets the system settings values that control the scaling factor for animations. The scale
controls the animation playback speed for animations that respect these settings. Animations
that do not respect the settings values will not be affected by this function. A lower scale
value results in a faster speed. A value of `0` disables animations entirely. When
animations are disabled services receive window change events more quickly which can reduce
the potential by confusion by reducing the time during which windows are in transition.

<br />

| Parameters ||
|---|---|
| `scale` | `float`: The scaling factor for all animations. <br /> |

<br />

| Parameters ||
|---|---|
| `enabled` | `boolean`: whether to enable or disable the cache. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if the cache and connection are not null, so the cache status is set. <br /> |

### setGestureDetectionPassthroughRegion

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

### onKeyEvent

Added in [API level 18](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
protected boolean onKeyEvent (KeyEvent event)
```

Callback that allows an accessibility service to observe the key events
before they are passed to the rest of the system. This means that the events
are first delivered here before they are passed to the device policy, the
input method, or applications.


**Note:** It is important that key events are handled in such
a way that the event stream that would be passed to the rest of the system
is well-formed. For example, handling the down event but not the up event
and vice versa would generate an inconsistent event stream.


**Note:** The key events delivered in this method are copies
and modifying them will have no effect on the events that will be passed
to the system. This method is intended to perform purely filtering
functionality.

<br />

<br />

| Parameters ||
|---|---|
| `event` | `KeyEvent`: The event to be processed. This event is owned by the caller and cannot be used after this method returns. Services wishing to use the event after this method returns should make a copy. <br /> |

| Returns ||
|---|---|
| `boolean` | If true then the event will be consumed and not delivered to applications, otherwise it will be delivered as usual. <br /> |

### onServiceConnected

Added in [API level 4](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
protected void onServiceConnected ()
```

This method is a part of the `https://developer.android.com/reference/android/accessibilityservice/AccessibilityService` lifecycle and is
called after the system has successfully bound to the service. If is
convenient to use this method for setting the `https://developer.android.com/reference/android/accessibilityservice/AccessibilityServiceInfo`.
