Andriod docs加载速度慢的问题解决

网上找了个类，

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileFilter;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Map;
import java.util.UUID;

public class AndroidDoc {

	private static final String ANDROID_SDK_HOME = "ANDROID_SDK_HOME";

	//private static final String TAG = "<link rel=\"stylesheet\"";
	
	//private static final String TAG = "href=\"http://fonts.googleapis.com/css?family=Roboto:regular,medium,thin,italic,mediumitalic,bold\" title=\"roboto\">";
	private static String androidSDKHome;

	public static void main(String[] args) {
		Map<String, String> map = System.getenv();
		androidSDKHome = map.get(ANDROID_SDK_HOME);
		if (androidSDKHome != null) {
			System.out.println("Detected the Android SDK Installation path:"
					+ androidSDKHome);
			File docs = new File(androidSDKHome + "\\docs");
			System.out.println("It will take several minutes, please wait...");
			traverse(docs);
			System.out
					.println("Operation Down!!! Now you can visit Android Doc without waiting...");
		} else {
			System.out
					.println("Please configure the Android SDK Environment variable (ANDROID_SDK_HOME)!");
		}
	}

	/**
	 * 遍历Android SDK安装目录下的docs目录
	 * 
	 * @param dir
	 */
	private static void traverse(File dir) {
		if (dir.isDirectory()) {
			File[] files = dir.listFiles(new FileFilter() {

					return false;

			});
			for (File file : files) {

					System.out.println("Scanning Folder:"
							+ file.getAbsolutePath());
					traverse(file);
				} else {
					doChange(file);
				}
			}
		}
	}

	/**
	 * 注释html中的某行Javascript代码
	 * 
	 * @param file
	 * @return
	 */
	private static boolean doChange(File file) {
		System.out.println("Extracting File:" + file.getAbsolutePath() + "...");
		String desPath = file.getParent() + "\\" + UUID.randomUUID().toString() + ".html";
		File des = new File(desPath);
		BufferedReader reader = null;
		BufferedWriter writer = null;
		try {
			des.createNewFile();
			reader = new BufferedReader(new FileReader(file));
			writer = new BufferedWriter(new FileWriter(des));
			String buffer;
			while ((buffer = reader.readLine()) != null) {
				if (buffer.trim().equalsIgnoreCase(TAG)) {
					buffer = "<!--" + TAG + "-->";
				}
				writer.write(buffer + "\n");
				writer.flush();
			}
			return true;
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();

	}

}

 

直接编译运行，注释的三行，三行代表替换三次

加载慢原因有两个一个是加载Google的字体，二个是加载Google的JS文件.
