navigating to a specific page with the mupdf android library

Question

How would I go about navigating to a specific page with the muPDF library? Or is there a way to make the library not remember which page I was last on in that pdf?

package com.artifex.mupdf;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Point;
import android.util.Log;

public class MuPDFPageView extends PageView {
    private final MuPDFCore mCore;

    public MuPDFPageView(Context c, MuPDFCore core, Point parentSize) {
        super(c, parentSize);
        mCore = core;
    }

    public String hitLinkPage(float x, float y) {
        // Since link highlighting was implemented, the super class
        // PageView has had sufficient information to be able to
        // perform this method directly. Making that change would
        // make MuPDFCore.hitLinkPage superfluous.
        float scale = mSourceScale * getWidth() / mSize.x ;


        float docRelX = (x - getLeft()) / scale;
        float docRelY = (y - getTop()) / scale;
           Log.d("Page Number", "hitLinkPage with page = " + mCore.hitLinkPage(mPageNumber, docRelX, docRelY));
        return mCore.hitLinkPage(mPageNumber, docRelX, docRelY);
    }

    @Override
    protected void drawPage(Bitmap bm, int sizeX, int sizeY, int patchX,
            int patchY, int patchWidth, int patchHeight) {
        mCore.drawPage(mPageNumber, bm, sizeX, sizeY, patchX, patchY,
                patchWidth, patchHeight);
    }

    @Override
    protected LinkInfo[] getLinkInfo() {
        return mCore.getPageLinks(mPageNumber);
    }
}
