/**
+ * The input device is a Bluetooth stylus.
+ * <p>
+ * Note that this bit merely indicates that an input device is capable of
+ * obtaining input from a Bluetooth stylus. To determine whether a given
+ * touch event was produced by a stylus, examine the tool type returned by
+ * {@link MotionEvent#getToolType(int)} for each individual pointer.
+ * </p><p>
+ * A single touch event may multiple pointers with different tool types,
+ * such as an event that has one pointer with tool type
+ * {@link MotionEvent#TOOL_TYPE_FINGER} and another pointer with tool type
+ * {@link MotionEvent#TOOL_TYPE_STYLUS}. So it is important to examine
+ * the tool type of each pointer, regardless of the source reported
+ * by {@link MotionEvent#getSource()}.
+ * </p><p>
+ * A bluetooth stylus generally receives its pressure and button state
+ * information from the stylus itself, and derives the rest from another
+ * source. For example, a Bluetooth stylus used in conjunction with a
+ * touchscreen would derive its contact position and pointer size from the
+ * touchscreen and may not be any more accurate than other tools such as
+ * fingers.
