Documenting PendingIntent identifying flags

 * {@link #FLAG_CANCEL_CURRENT} or {@link #FLAG_UPDATE_CURRENT} to either

 * cancel or modify whatever current PendingIntent is associated with the

 * Intent you are supplying.

 *

 * <p>Also note that flags like {@link #FLAG_ONE_SHOT} or {@link #FLAG_IMMUTABLE} describe the

 * PendingIntent instance and thus, are used to identify it. Any calls to retrieve or modify a

 * PendingIntent created with these flags will also require these flags to be supplied in

 * conjunction with others. E.g. To retrieve an existing PendingIntent created with

 * FLAG_ONE_SHOT, <b>both</b> FLAG_ONE_SHOT and FLAG_NO_CREATE need to be supplied.
