Android 参考文档本地打开缓慢，JAVA解决方案

关于Android Develop 文档明明本地下载了，但在浏览器里打开还是很卡，原因是html文档中有链接Google服务器的Link和script。

网上有很多解决方案，其中一种是删除里面所有链接Google服务器的Link和script。

我在网上下载的JAVA代码这两行修饰css代码是怎么也删不掉，后来我读完代码发现有些bug.

<link rel="stylesheet"
href="http://fonts.googleapis.com/css?family=Roboto+Condensed">
<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Roboto:light,regular,medium,thin,italic,mediumitalic,bold"
title="roboto">

以下是我参考别人的代码修改的JAVA代码解决方案，与别人JAVA代码的不同之处是能完全删除所有链接Google服务器的Link和script。

package deleteAndroidDoc;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class FormatDoc {
    public static int j = 1;

    /**
     * @param args
     */
    public static void main(String[] args) {

//        写你的文件所在的文件夹绝对路径
        File file = new File("G:/Android Docs");
        searchDirectory(file, 0);
        System.out.println("OVER");
    }

    public static void searchDirectory(File f, int depth) {
        if (!f.isDirectory()) {
            String fileName = f.getName();
            if (fileName.matches(".*.{1}html")) {
                String src = "<link rel=\"stylesheet\"";
                String src1 = "href=\"http://fonts.googleapis.com/css\\?family=Roboto\\+Condensed\">";
                String src2 = "<script src=\"http://www.google.com/jsapi\" type=\"text/javascript\"></script>";
                String src3 = "<script src=\"https://developer.android.com/ytblogger_lists_unified.js\" type=\"text/javascript\"></script>";

                String src5 = "  title=\"roboto\">";
                String dst = "";
                // 匹配相应的并用""(空字符串)替代
                annotation(f, src, dst);
                annotation(f, src1, dst);
                annotation(f, src2, dst);
                annotation(f, src3, dst);
                annotation(f, src4, dst);
                annotation(f, src5, dst);
            }
        } else {
            File[] fs = f.listFiles();
            depth++;
            for (int i = 0; i < fs.length; ++i) {
                File file = fs[i];
                searchDirectory(file, depth);
            }
        }
    }

    public static void annotation(File f, String src, String dst) {
        String content = FormatDoc.read(f);
        content = content.replaceFirst(src, dst);
        int ll = content.lastIndexOf(src);
        System.out.println(ll);
        FormatDoc.write(content, f);
        System.out.println(j++);
        return;

    }

    public static String read(File src) {
        StringBuffer res = new StringBuffer();
        String line = null;
        try {
            BufferedReader reader = new BufferedReader(new FileReader(src));
            int i = 0;
            while ((line = reader.readLine()) != null) {
                if (i != 0) {
                    res.append('\n');
                }
                res.append(line);
                i++;
            }
            reader.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return res.toString();
    }

    public static boolean write(String cont, File dist) {
        try {
            BufferedWriter writer = new BufferedWriter(new FileWriter(dist));
            writer.write(cont);
            writer.flush();
            writer.close();
            return true;
