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.

Added in API level 31

public static final int FLAG_REQUEST_2_FINGER_PASSTHROUGH

This flag requests that when when FLAG_REQUEST_MULTI_FINGER_GESTURES is enabled, two-finger passthrough gestures are re-enabled. Two-finger swipe gestures are not detected, but instead passed through as one-finger gestures. In addition, three-finger swipes from the bottom of the screen are not detected, and instead are passed through unchanged. If FLAG_REQUEST_MULTI_FINGER_GESTURES is disabled this flag has no effect.

Services that want to set this flag have to declare this capability in their meta-data by setting the attribute #canRequestFilterKeyEvents canRequestFilterKeyEvents to true, otherwise this flag will be ignored. For how to declare the meta-data of a service refer to android.accessibilityservice.AccessibilityService.SERVICE_META_DATA AccessibilityService.SERVICE_META_DATA.

See also:

• R.styleable.AccessibilityService_canRequestFilterKeyEvents

Constant Value: 32 (0x00000020)

FLAG_REQUEST_FINGERPRINT_GESTURES

Added in API level 26

public static final int FLAG_REQUEST_FINGERPRINT_GESTURES

This flag requests that all fingerprint gestures be sent to the accessibility service.

Services that want to set this flag have to declare the capability to retrieve window content in their meta-data by setting the attribute R.attr.canRequestFingerprintGestures to true, otherwise this flag will be ignored.

Constant Value: 4096 (0x00001000)

FLAG_REQUEST_SHORTCUT_WARNING_DIALOG_SPOKEN_FEEDBACK

Added in API level 29

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: 1024 (0x00000400)

FLAG_REQUEST_TOUCH_EXPLORATION_MODE

Added in API level 16

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 canRequestTouchExplorationMode to true. Otherwise, this flag will be ignored. For how to declare the meta-data of a service refer to android.accessibilityservice.AccessibilityService.SERVICE_META_DATA 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.

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 AccessibilityEvent.TYPE_WINDOWS_CHANGED events, calling AccessibilityServiceAccessibilityService.getWindows() will return an empty list, and 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 canRetrieveWindowContent to true, otherwise this flag will be ignored. For how to declare the meta-data of a service refer to android.accessibilityservice.AccessibilityService.SERVICE_META_DATA AccessibilityService.SERVICE_META_DATA.

Constant Value: 64 (0x00000040)

FLAG_SEND_MOTION_EVENTS

Added in API level 31

public static final int FLAG_SEND_MOTION_EVENTS

This flag requests that when when 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 FLAG_REQUEST_TOUCH_EXPLORATION_MODE is disabled this flag has no effect.

Constant Value: 16384 (0x00004000)

FLAG_SERVICE_HANDLES_DOUBLE_TAP

Added in API level 30

public static final int FLAG_SERVICE_HANDLES_DOUBLE_TAP

This flag requests that when FLAG_REQUEST_TOUCH_EXPLORATION_MODE is enabled, double tap and double tap and hold gestures are dispatched to the service rather than being handled by the framework. If FLAG_REQUEST_TOUCH_EXPLORATION_MODE is disabled this flag has no effect.

Added in API level 4

public int flags

This field represents a set of flags used for configuring an AccessibilityService.

Can be dynamically set at runtime.

Note: Accessibility services with targetSdkVersion greater than API 29 cannot dynamically set the FLAG_REQUEST_ACCESSIBILITY_BUTTON at runtime. It must be specified in the accessibility service metadata file.

See also:

• DEFAULT
• FLAG_INCLUDE_NOT_IMPORTANT_VIEWS
• FLAG_REQUEST_TOUCH_EXPLORATION_MODE
• FLAG_REQUEST_ENHANCED_WEB_ACCESSIBILITY

notificationTimeout

Added in API level 4

public long notificationTimeout

The timeout, in milliseconds, after the most recent event of a given type before an AccessibilityService is notified.

Can be dynamically set at runtime.

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.

packageNames

Added in API level 4

public String[] packageNames

The package names an AccessibilityService is interested in. Setting to null is equivalent to all packages.

Can be dynamically set at runtime.

Public constructors

AccessibilityServiceInfo

Added in API level 4

public AccessibilityServiceInfo ()

Creates a new instance.

Public methods

capabilityToString

Added in API level 18

public static String capabilityToString (int capability)

Returns the string representation of a capability. For example, CAPABILITY_CAN_RETRIEVE_WINDOW_CONTENT is represented by the string CAPABILITY_CAN_RETRIEVE_WINDOW_CONTENT.

Parameters
capability	int: The capability.

Returns
String	The string representation.

describeContents

Added in API level 4

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 writeToParcel(android.os.Parcel, int), the return value of this method must include the 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 CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 4

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

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 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 equals 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 equals 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.

isAccessibilityTool

This value can be dynamically set at runtime by AccessibilityService#setServiceInfo(AccessibilityServiceInfo).

Parameters
timeout	int: The timeout in milliseconds. Value is 0 or greater

See also:

• R.styleable.AccessibilityService_interactiveUiTimeout

setMotionEventSources

Added in API level 34

public void setMotionEventSources (int motionEventSources)

Sets the bit mask of InputDevice sources that the accessibility service wants to listen to for generic MotionEvents.

Including an InputDevice source that does not send MotionEvents is effectively a no-op for that source, since you will not receive any events from that source.

See InputDevice for complete source definitions. Many input devices send InputEvents from more than one type of source so you may need to include multiple MotionEvent sources here, in addition to using AccessibilityService#onKeyEvent to listen to KeyEvents.

Note: 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 InputDevice sources. Value is either 0 or a combination of InputDevice.SOURCE_MOUSE, InputDevice.SOURCE_STYLUS, InputDevice.SOURCE_BLUETOOTH_STYLUS, InputDevice.SOURCE_TRACKBALL, InputDevice.SOURCE_MOUSE_RELATIVE, InputDevice.SOURCE_TOUCHPAD, InputDevice.SOURCE_TOUCH_NAVIGATION, InputDevice.SOURCE_ROTARY_ENCODER, InputDevice.SOURCE_JOYSTICK, InputDevice.SOURCE_SENSOR, and InputDevice.SOURCE_TOUCHSCREEN

See also:

• AccessibilityService.onMotionEvent(MotionEvent)

setNonInteractiveUiTimeoutMillis

Added in API level 29

public void setNonInteractiveUiTimeoutMillis (int timeout)
