Key event flags.

Properties
`AKEY_EVENT_FLAG_CANCELED`	When associated with up key events, this indicates that the key press has been canceled. Typically this is used with virtual touch screen keys, where the user can slide from the virtual key area on to the display: in that case, the application will receive a canceled up event and should not perform the action normally associated with the key. Note that for this to work, the application can not perform an action for a key until it receives an up or the long press timeout has expired.
`AKEY_EVENT_FLAG_CANCELED_LONG_PRESS`	Set when a key event has AKEY_EVENT_FLAG_CANCELED set because a long press action was executed while it was down.
`AKEY_EVENT_FLAG_EDITOR_ACTION`	This mask is used for compatibility, to identify enter keys that are coming from an IME whose enter key has been auto-labelled "next" or "done". This allows TextView to dispatch these as normal enter keys for old applications, but still do the appropriate action when receiving them.
`AKEY_EVENT_FLAG_FALLBACK`	Set when a key event has been synthesized to implement default behavior for an event that the application did not handle. Fallback key events are generated by unhandled trackball motions (to emulate a directional keypad) and by certain unhandled key presses that are declared in the key map (such as special function numeric keypad keys when numlock is off).
`AKEY_EVENT_FLAG_FROM_SYSTEM`	This mask is set if an event was known to come from a trusted part of the system. That is, the event is known to come from the user, and could not have been spoofed by a third party component.
`AKEY_EVENT_FLAG_KEEP_TOUCH_MODE`	This mask is set if we don't want the key event to cause us to leave touch mode.
`AKEY_EVENT_FLAG_LONG_PRESS`	This flag is set for the first key repeat that occurs after the long press timeout.
`AKEY_EVENT_FLAG_SOFT_KEYBOARD`	This mask is set if the key event was generated by a software keyboard.
`AKEY_EVENT_FLAG_TRACKING`	Set for AKEY_EVENT_ACTION_UP when this event's key code is still being tracked from its initial down. That is, somebody requested that tracking started on the key down and a long press has not caused the tracking to be canceled.
`AKEY_EVENT_FLAG_VIRTUAL_HARD_KEY`	This key event was generated by a virtual (on-screen) hard key area. Typically this is an area of the touchscreen, outside of the regular display, dedicated to "hardware" buttons.
`AKEY_EVENT_FLAG_WOKE_HERE`	This mask is set if the device woke because of this key event.

Motion event actions.

Properties
`AMOTION_EVENT_ACTION_BUTTON_PRESS`
`AMOTION_EVENT_ACTION_BUTTON_RELEASE`
`AMOTION_EVENT_ACTION_CANCEL`	The current gesture has been aborted. You will not receive any more points in it. You should treat this as an up event, but not perform any action that you normally would.
`AMOTION_EVENT_ACTION_DOWN`	A pressed gesture has started, the motion contains the initial starting location.
`AMOTION_EVENT_ACTION_HOVER_ENTER`	The pointer is not down but has entered the boundaries of a window or view.
`AMOTION_EVENT_ACTION_HOVER_EXIT`	The pointer is not down but has exited the boundaries of a window or view.
`AMOTION_EVENT_ACTION_HOVER_MOVE`	A change happened but the pointer is not down (unlike AMOTION_EVENT_ACTION_MOVE). The motion contains the most recent point, as well as any intermediate points since the last hover move event.
`AMOTION_EVENT_ACTION_MASK`	Bit mask of the parts of the action code that are the action itself.
`AMOTION_EVENT_ACTION_MOVE`	A change has happened during a press gesture (between AMOTION_EVENT_ACTION_DOWN and AMOTION_EVENT_ACTION_UP). The motion contains the most recent point, as well as any intermediate points since the last down or move event.
`AMOTION_EVENT_ACTION_OUTSIDE`	A movement has happened outside of the normal bounds of the UI element. This does not provide a full gesture, but only the initial location of the movement/touch.
`AMOTION_EVENT_ACTION_POINTER_DOWN`	A non-primary pointer has gone down. The bits in AMOTION_EVENT_ACTION_POINTER_INDEX_MASK indicate which pointer changed.
`AMOTION_EVENT_ACTION_POINTER_INDEX_MASK`	Bits in the action code that represent a pointer index, used with AMOTION_EVENT_ACTION_POINTER_DOWN and AMOTION_EVENT_ACTION_POINTER_UP. Shifting down by AMOTION_EVENT_ACTION_POINTER_INDEX_SHIFT provides the actual pointer index where the data for the pointer going up or down can be found.
`AMOTION_EVENT_ACTION_POINTER_UP`	A non-primary pointer has gone up. The bits in AMOTION_EVENT_ACTION_POINTER_INDEX_MASK indicate which pointer changed.
`AMOTION_EVENT_ACTION_SCROLL`	The motion event contains relative vertical and/or horizontal scroll offsets. Use AMotionEvent_getAxisValue to retrieve the information from AMOTION_EVENT_AXIS_VSCROLL and AMOTION_EVENT_AXIS_HSCROLL. The pointer may or may not be down when this event is dispatched. This action is always delivered to the winder under the pointer, which may not be the window currently touched.
`AMOTION_EVENT_ACTION_UP`	A pressed gesture has finished, the motion contains the final release location as well as any intermediate points since the last down or move event.

`AMOTION_EVENT_AXIS_GESTURE_PINCH_SCALE_FACTOR`	Axis constant: pinch scale factor of a motion event. For a touch pad, reports the change in distance between the fingers when the user is making a pinch gesture, as a proportion of that distance when the gesture was last reported. For example, if the fingers were 50 units apart and are now 52 units apart, the scale factor would be 1.04. These values are relative to the state from the last event, not accumulated, so developers should make sure to process this axis value for all batched historical events. This axis is only set on the first pointer in a motion event.
`AMOTION_EVENT_AXIS_GESTURE_SCROLL_X_DISTANCE`	Axis constant: X scroll distance axis of a motion event. For a touch pad, reports the distance that should be scrolled in the X axis as a result of the user's two-finger scroll gesture, in display pixels. These values are relative to the state from the last event, not accumulated, so developers should make sure to process this axis value for all batched historical events. This axis is only set on the first pointer in a motion event.
`AMOTION_EVENT_AXIS_GESTURE_SCROLL_Y_DISTANCE`	Axis constant: Y scroll distance axis of a motion event. The same as AMOTION_EVENT_AXIS_GESTURE_SCROLL_X_DISTANCE, but for the Y axis.

`AMOTION_EVENT_AXIS_GESTURE_X_OFFSET`	Axis constant: X gesture offset axis of a motion event. For a touch pad, reports the distance that a swipe gesture has moved in the X axis, as a proportion of the touch pad's size. For example, if a touch pad is 1000 units wide, and a swipe gesture starts at X = 500 then moves to X = 400, this axis would have a value of -0.1. These values are relative to the state from the last event, not accumulated, so developers should make sure to process this axis value for all batched historical events. This axis is only set on the first pointer in a motion event.
`AMOTION_EVENT_AXIS_GESTURE_Y_OFFSET`	Axis constant: Y gesture offset axis of a motion event. The same as AMOTION_EVENT_AXIS_GESTURE_X_OFFSET, but for the Y axis.

`AMOTION_EVENT_AXIS_ORIENTATION`	Axis constant: Orientation axis of a motion event. For a touch screen or touch pad, reports the orientation of the finger or tool in radians relative to the vertical plane of the device. An angle of 0 radians indicates that the major axis of contact is oriented upwards, is perfectly circular or is of unknown orientation. A positive angle indicates that the major axis of contact is oriented to the right. A negative angle indicates that the major axis of contact is oriented to the left. The full range is from -PI/2 radians (finger pointing fully left) to PI/2 radians (finger pointing fully right). For a stylus, the orientation indicates the direction in which the stylus is pointing in relation to the vertical axis of the current orientation of the screen. The range is from -PI radians to PI radians, where 0 is pointing up, -PI/2 radians is pointing left, -PI or PI radians is pointing down, and PI/2 radians is pointing right. See also AMOTION_EVENT_AXIS_TILT.
`AMOTION_EVENT_AXIS_PRESSURE`	Axis constant: Pressure axis of a motion event. For a touch screen or touch pad, reports the approximate pressure applied to the surface by a finger or other tool. The value is normalized to a range from 0 (no pressure at all) to 1 (normal pressure), although values higher than 1 may be generated depending on the calibration of the input device. For a trackball, the value is set to 1 if the trackball button is pressed or 0 otherwise. For a mouse, the value is set to 1 if the primary mouse button is pressed or 0 otherwise.
`AMOTION_EVENT_AXIS_RELATIVE_X`	Axis constant: The movement of x position of a motion event. For a mouse, reports a difference of x position between the previous position. This is useful when pointer is captured, in that case the mouse pointer doesn't change the location but this axis reports the difference which allows the app to see how the mouse is moved.
`AMOTION_EVENT_AXIS_RELATIVE_Y`	Axis constant: The movement of y position of a motion event. Same as AMOTION_EVENT_AXIS_RELATIVE_X, but for y position.
`AMOTION_EVENT_AXIS_RTRIGGER`	Axis constant: Right Trigger axis of a motion event. For a joystick, reports the absolute position of the right trigger control. The value is normalized to a range from 0.0 (released) to 1.0 (fully pressed).

`AMOTION_EVENT_AXIS_RZ`	Axis constant: Z Rotation axis of a motion event. For a joystick, reports the absolute rotation angle about the Z axis. The value is normalized to a range from -1.0 (counter-clockwise) to 1.0 (clockwise). On game pads with two analog joysticks, this axis is often reinterpreted to report the absolute Y position of the second joystick instead.
`AMOTION_EVENT_AXIS_SCROLL`	Axis constant: Generic scroll axis of a motion event. This is used for scroll axis motion events that can't be classified as strictly vertical or horizontal. The movement of a rotating scroller is an example of this.
`AMOTION_EVENT_AXIS_SIZE`	Axis constant: Size axis of a motion event. For a touch screen or touch pad, reports the approximate size of the contact area in relation to the maximum detectable size for the device. The value is normalized to a range from 0 (smallest detectable size) to 1 (largest detectable size), although it is not a linear scale. This value is of limited use. To obtain calibrated size information, see AMOTION_EVENT_AXIS_TOUCH_MAJOR or AMOTION_EVENT_AXIS_TOOL_MAJOR.
`AMOTION_EVENT_AXIS_THROTTLE`	Axis constant: Throttle axis of a motion event. For a joystick, reports the absolute position of the throttle control. The value is normalized to a range from 0.0 (fully open) to 1.0 (fully closed).
`AMOTION_EVENT_AXIS_TILT`	Axis constant: Tilt axis of a motion event. For a stylus, reports the tilt angle of the stylus in radians where 0 radians indicates that the stylus is being held perpendicular to the surface, and PI/2 radians indicates that the stylus is being held flat against the surface.
`AMOTION_EVENT_AXIS_TOOL_MAJOR`	Axis constant: ToolMajor axis of a motion event. For a touch screen, reports the length of the major axis of an ellipse that represents the size of the approaching finger or tool used to make contact. For a touch pad, reports the length of the major axis of an ellipse that represents the size of the approaching finger or tool used to make contact. The units are device-dependent. When the touch is circular, the major and minor axis lengths will be equal to one another. The tool size may be larger than the touch size since the tool may not be fully in contact with the touch sensor.
`AMOTION_EVENT_AXIS_TOOL_MINOR`	Axis constant: ToolMinor axis of a motion event. For a touch screen, reports the length of the minor axis of an ellipse that represents the size of the approaching finger or tool used to make contact. For a touch pad, reports the length of the minor axis of an ellipse that represents the size of the approaching finger or tool used to make contact. The units are device-dependent. When the touch is circular, the major and minor axis lengths will be equal to one another. The tool size may be larger than the touch size since the tool may not be fully in contact with the touch sensor.
`AMOTION_EVENT_AXIS_TOUCH_MAJOR`	Axis constant: TouchMajor axis of a motion event. For a touch screen, reports the length of the major axis of an ellipse that represents the touch area at the point of contact. The units are display pixels. For a touch pad, reports the length of the major axis of an ellipse that represents the touch area at the point of contact. The units are device-dependent.
`AMOTION_EVENT_AXIS_TOUCH_MINOR`	Axis constant: TouchMinor axis of a motion event. For a touch screen, reports the length of the minor axis of an ellipse that represents the touch area at the point of contact. The units are display pixels. For a touch pad, reports the length of the minor axis of an ellipse that represents the touch area at the point of contact. The units are device-dependent. When the touch is circular, the major and minor axis lengths will be equal to one another.
`AMOTION_EVENT_AXIS_VSCROLL`	Axis constant: Vertical Scroll axis of a motion event. For a mouse, reports the relative movement of the vertical scroll wheel. The value is normalized to a range from -1.0 (down) to 1.0 (up). This axis should be used to scroll views vertically.
`AMOTION_EVENT_AXIS_WHEEL`	Axis constant: Wheel axis of a motion event. For a joystick, reports the absolute position of the steering wheel control. The value is normalized to a range from -1.0 (turn left) to 1.0 (turn right).
`AMOTION_EVENT_AXIS_X`	Axis constant: X axis of a motion event. For a touch screen, reports the absolute X screen position of the center of the touch contact area. The units are display pixels. For a touch pad, reports the absolute X surface position of the center of the touch contact area. The units are device-dependent. For a mouse, reports the absolute X screen position of the mouse pointer. The units are display pixels. For a trackball, reports the relative horizontal displacement of the trackball. The value is normalized to a range from -1.0 (left) to 1.0 (right). For a joystick, reports the absolute X position of the joystick. The value is normalized to a range from -1.0 (left) to 1.0 (right).
`AMOTION_EVENT_AXIS_Y`	Axis constant: Y axis of a motion event. For a touch screen, reports the absolute Y screen position of the center of the touch contact area. The units are display pixels. For a touch pad, reports the absolute Y surface position of the center of the touch contact area. The units are device-dependent. For a mouse, reports the absolute Y screen position of the mouse pointer. The units are display pixels. For a trackball, reports the relative vertical displacement of the trackball. The value is normalized to a range from -1.0 (up) to 1.0 (down). For a joystick, reports the absolute Y position of the joystick. The value is normalized to a range from -1.0 (up or far) to 1.0 (down or near).
`AMOTION_EVENT_AXIS_Z`	Axis constant: Z axis of a motion event. For a joystick, reports the absolute Z position of the joystick. The value is normalized to a range from -1.0 (high) to 1.0 (low). On game pads with two analog joysticks, this axis is often reinterpreted to report the absolute X position of the second joystick instead.
`AMOTION_EVENT_MAXIMUM_VALID_AXIS_VALUE`	Note: This is not an "Axis constant". It does not represent any axis, nor should it be used to represent any axis. It is a constant holding the value of the largest defined axis value, to make some computations (like iterating through all possible axes) cleaner. Please update the value accordingly if you add a new axis.

AMotionClassification

Declared in android/input.h

 AMotionClassification

Constants that identify different gesture classification types.

Properties
`AMOTION_EVENT_CLASSIFICATION_AMBIGUOUS_GESTURE`	Classification constant: Ambiguous gesture. The user's intent with respect to the current event stream is not yet determined. Events starting in AMOTION_EVENT_CLASSIFICATION_AMBIGUOUS_GESTURE will eventually resolve into either AMOTION_EVENT_CLASSIFICATION_DEEP_PRESS or AMOTION_EVENT_CLASSIFICATION_NONE. Gestural actions, such as scrolling, should be inhibited until the classification resolves to another value or the event stream ends.
`AMOTION_EVENT_CLASSIFICATION_DEEP_PRESS`	Classification constant: Deep press. The current event stream represents the user intentionally pressing harder on the screen. This classification type should be used to accelerate the long press behaviour.
`AMOTION_EVENT_CLASSIFICATION_MULTI_FINGER_SWIPE`	Classification constant: multi-finger swipe. The current event stream represents the user swiping with three or more fingers on a touchpad. Unlike two-finger swipes, these are only to be handled by the system UI, which is why they have a separate constant from two-finger swipes.
`AMOTION_EVENT_CLASSIFICATION_NONE`	Classification constant: None. No additional information is available about the current motion event stream.
`AMOTION_EVENT_CLASSIFICATION_PINCH`	Classification constant: pinch. The current event stream represents the user pinching with two fingers on a touchpad. The gesture is centered around the current cursor position.
`AMOTION_EVENT_CLASSIFICATION_TWO_FINGER_SWIPE`	Classification constant: touchpad two-finger swipe. The current event stream represents the user swiping with two fingers on a touchpad.
