* The input device is a Bluetooth stylus.

* Note that this bit merely indicates that an input device is capable of

* 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.
