To obtain calibrated size information, see {@link AMOTION_EVENT_AXIS_TOUCH_MAJOR} or {@link AMOTION_EVENT_AXIS_TOOL_MAJOR}.

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.

- 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.

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.

- 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.
