android doc 本地文档加载慢的解决办法

从来都是*上谷歌官网查文档，但是有时没办法*，就得用sdk本地的doc文档了，由于文档内部的一些javascript,font等也需要访问Google来加载，导致了打开本地网页也巨慢无比，甚至转了半天圈都打不开，后来经过查找，发现可通过360提供的资源来替换Google的，这样打开的就快得多了。话不多说，上代码批量修改：

package test.qin.fileio;

import java.io.BufferedReader;

import java.io.File;

import java.io.FileNotFoundException;

import java.io.FileReader;

import java.io.FileWriter;

import java.io.IOException;

import java.util.concurrent.ExecutorService;

import java.util.concurrent.Executors;

public class Main {

<span style="white-space:pre">	</span>ExecutorService executors = Executors.newFixedThreadPool(2);

<span style="white-space:pre">	</span>public static void main(String[] args) throws InterruptedException {

<span style="white-space:pre">		</span>Main m = new Main();

<span style="white-space:pre">		</span>m.googleCDNChange(f);
