概述:Java解析apk文件,获取apk文件里的包名,版本号,图标文件等;
功能:可以提供给windows和linux平台使用;
原理:利用aapt.exe或者aapt这些anroid平台解析apk文件的工具,借用终端shell调用命令解析输出信息;
代码:
这里贴出一些关键代码,并给出代码注释,如下

上面加上阴影的部分代码,我想基本都是很好理解的,获取当前运行的操作系统类型,适配上相应的指令和软件,这样可以跨平台操作,而不需要修改代码;
获取到相应软件后,对apk文件一行一行的进行解析,将相应的属性存到javaBean中,并将apk文件图片通过流的方式写出到文件系统中,
1 package com.apkutils; 2 3 import java.io.BufferedInputStream; 4 import java.io.BufferedOutputStream; 5 import java.io.File; 6 import java.io.FileOutputStream; 7 import java.io.IOException; 8 import java.io.InputStream; 9 import java.util.zip.ZipEntry; 10 import java.util.zip.ZipFile; 11 12 13 /** 14 * 通过ApkInfo 里的applicationIcon从APK里解压出icon图片并存放到磁盘上 15 * @author @author tony 16 */ 17 public class IconUtil { 18 19 /** 20 * 从指定的apk文件里获取指定file的流 21 * @param apkpath 22 * @param fileName 23 * @return 24 */ 25 public static InputStream extractFileFromApk(String apkpath, String fileName) { 26 try { 27 ZipFile zFile = new ZipFile(apkpath); 28 ZipEntry entry = zFile.getEntry(fileName); 29 entry.getComment(); 30 entry.getCompressedSize(); 31 entry.getCrc(); 32 entry.isDirectory(); 33 entry.getSize(); 34 entry.getMethod(); 35 InputStream stream = zFile.getInputStream(entry); 36 return stream; 37 } catch (IOException e) { 38 e.printStackTrace(); 39 } 40 return null; 41 } 42 43 public static void extractFileFromApk(String apkpath, String fileName, String outputPath) throws Exception { 44 InputStream is = extractFileFromApk(apkpath, fileName); 45 46 File file = new File(outputPath); 47 BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file), 1024); 48 byte[] b = new byte[1024]; 49 BufferedInputStream bis = new BufferedInputStream(is, 1024); 50 while(bis.read(b) != -1){ 51 bos.write(b); 52 } 53 bos.flush(); 54 is.close(); 55 bis.close(); 56 bos.close(); 57 } 58 }
这里没什么好说的,就是用JavaIO中zip的方式解析文件,并拿出图标写出到指定文件目录
