Remarks

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 AccessibilityEvents 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.

<div class="special reference"> <h3>Developer Guides</h3>

For more information about creating AccessibilityServices, read the Accessibility developer guide.

</div>

<h3>Lifecycle</h3>

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 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 AccessibilityService#disableSelf().

<h3>Declaration</h3>

An accessibility is declared as any other service in an AndroidManifest.xml, but it must do two things: <ul> <li> Specify that it handles the "android.accessibilityservice.AccessibilityService" android.content.Intent. </li> <li> Request the android.Manifest.permission#BIND_ACCESSIBILITY_SERVICE permission to ensure that only the system can bind to it. </li> </ul> If either of these items is missing, the system will ignore the accessibility service. Following is an example declaration:

&lt;service android:name=".MyAccessibilityService"
                    android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"&gt;
                &lt;intent-filter&gt;
                    &lt;action android:name="android.accessibilityservice.AccessibilityService" /&gt;
                &lt;/intent-filter&gt;
                . . .
            &lt;/service&gt;

<h3>Configuration</h3>

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:

<ul> <li> Providing a #SERVICE_META_DATA meta-data entry in the manifest when declaring the service. A service declaration with a meta-data tag is presented below:

&lt;service android:name=".MyAccessibilityService"&gt;
                &lt;intent-filter&gt;
                    &lt;action android:name="android.accessibilityservice.AccessibilityService" /&gt;
                &lt;/intent-filter&gt;
                &lt;meta-data android:name="android.accessibilityservice" android:resource="@xml/accessibilityservice" /&gt;
            &lt;/service&gt;

<p class="note"> <strong>Note:</strong> This approach enables setting all properties. </p>

For more details refer to #SERVICE_META_DATA and &lt;{@link android.R.styleable#AccessibilityService accessibility-service}&gt;.

</li> <li> Calling AccessibilityService#setServiceInfo(AccessibilityServiceInfo). Note that this method can be called any time to dynamically change the service configuration. <p class="note"> <strong>Note:</strong> This approach enables setting only dynamically configurable properties: AccessibilityServiceInfo#eventTypes, AccessibilityServiceInfo#feedbackType, AccessibilityServiceInfo#flags, AccessibilityServiceInfo#notificationTimeout, AccessibilityServiceInfo#packageNames</p>

For more details refer to AccessibilityServiceInfo.

</li> </ul> <h3>Retrieving window content</h3>

A service can specify in its declaration that it can retrieve window content which is represented as a tree of AccessibilityWindowInfo and AccessibilityNodeInfo objects. Note that declaring this capability requires that the service declares its configuration via an XML resource referenced by #SERVICE_META_DATA.

Window content may be retrieved with AccessibilityEvent#getSource() AccessibilityEvent.getSource(), AccessibilityService#findFocus(int), AccessibilityService#getWindows(), or AccessibilityService#getRootInActiveWindow().

<p class="note"> <strong>Note</strong> 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. </p> <h3>Drawing Accessibility Overlays</h3>

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 #attachAccessibilityOverlayToWindow. 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 #attachAccessibilityOverlayToDisplay.

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 AccessibilityNodeInfo as discussed above and call AccessibilityNodeInfo#getBoundsInWindow.

<h3>Notification strategy</h3>

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

<p class="note"> <strong>Note:</strong> 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.</p> <h3>Event types</h3> <ul> <li>AccessibilityEvent#TYPE_VIEW_CLICKED</li> <li>AccessibilityEvent#TYPE_VIEW_LONG_CLICKED</li> <li>AccessibilityEvent#TYPE_VIEW_FOCUSED</li> <li>AccessibilityEvent#TYPE_VIEW_SELECTED</li> <li>AccessibilityEvent#TYPE_VIEW_TEXT_CHANGED</li> <li>AccessibilityEvent#TYPE_WINDOW_STATE_CHANGED</li> <li>AccessibilityEvent#TYPE_NOTIFICATION_STATE_CHANGED</li> <li>AccessibilityEvent#TYPE_TOUCH_EXPLORATION_GESTURE_START</li> <li>AccessibilityEvent#TYPE_TOUCH_EXPLORATION_GESTURE_END</li> <li>AccessibilityEvent#TYPE_VIEW_HOVER_ENTER</li> <li>AccessibilityEvent#TYPE_VIEW_HOVER_EXIT</li> <li>AccessibilityEvent#TYPE_VIEW_SCROLLED</li> <li>AccessibilityEvent#TYPE_VIEW_TEXT_SELECTION_CHANGED</li> <li>AccessibilityEvent#TYPE_WINDOW_CONTENT_CHANGED</li> <li>AccessibilityEvent#TYPE_ANNOUNCEMENT</li> <li>AccessibilityEvent#TYPE_GESTURE_DETECTION_START</li> <li>AccessibilityEvent#TYPE_GESTURE_DETECTION_END</li> <li>AccessibilityEvent#TYPE_TOUCH_INTERACTION_START</li> <li>AccessibilityEvent#TYPE_TOUCH_INTERACTION_END</li> <li>AccessibilityEvent#TYPE_VIEW_ACCESSIBILITY_FOCUSED</li> <li>AccessibilityEvent#TYPE_WINDOWS_CHANGED</li> <li>AccessibilityEvent#TYPE_VIEW_ACCESSIBILITY_FOCUS_CLEARED</li> </ul> <h3>Feedback types</h3> <ul> <li>AccessibilityServiceInfo#FEEDBACK_AUDIBLE</li> <li>AccessibilityServiceInfo#FEEDBACK_HAPTIC</li> <li>AccessibilityServiceInfo#FEEDBACK_SPOKEN</li> <li>AccessibilityServiceInfo#FEEDBACK_VISUAL</li> <li>AccessibilityServiceInfo#FEEDBACK_GENERIC</li> <li>AccessibilityServiceInfo#FEEDBACK_BRAILLE</li> </ul>
