Fix API level in documentation to refer to MNC

     * the position values have different meanings.

     * <br>

     * If looping is currently enabled and the new position is greater than or equal to the

     * loop end marker, the behavior varies by API level: for API level 22 and above,

     * loop end marker, the behavior varies by API level:

     * as of {@link android.os.Build.VERSION_CODES#MNC},

     * the looping is first disabled and then the position is set.

     * For earlier API levels, the behavior is unspecified.

     * @return error code or success, see {@link #SUCCESS}, {@link #ERROR_BAD_VALUE},

     * {@link #ERROR_BAD_VALUE} is returned.

     * The loop range is the interval [startInFrames, endInFrames).

     * <br>

     * For API level 22 and above, the position is left unchanged,

     * As of {@link android.os.Build.VERSION_CODES#MNC}, the position is left unchanged,

     * unless it is greater than or equal to the loop end marker, in which case

     * it is forced to the loop start marker.

     * For earlier API levels, the effect on position is unspecified.

     * The track must be stopped or paused, and

     * the track's creation mode must be {@link #MODE_STATIC}.

     * <p>

     * For API level 22 and above, also resets the value returned by

     * As of {@link android.os.Build.VERSION_CODES#MNC}, also resets the value returned by

     * {@link #getPlaybackHeadPosition()} to zero.

     * For earlier API levels, the reset behavior is unspecified.

     * <p>

     * {@link #setPlaybackHeadPosition(int)} to zero

     * is recommended instead when the reset of {@link #getPlaybackHeadPosition} is not needed.

     * Use {@link #setPlaybackHeadPosition(int)} with a zero position

     * if the reset of <code>getPlaybackHeadPosition()</code> is not needed.

     * @return error code or success, see {@link #SUCCESS}, {@link #ERROR_BAD_VALUE},

     *  {@link #ERROR_INVALID_OPERATION}
