Android-程序反编译

同样为了比对我们看一下ApkInstaller.java的源代码如下:
view plaincopy to clipboardprint?packagecom.tutor.apkinstaller;importandroid.app.Activity;importandroid.os.Bundle;importandroid.webkit.WebSettings;importandroid.webkit.WebView;publicclassApkInstallerextendsActivity{privateWebViewapkWeb;@OverridepublicvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);setContentView(yout.main);apkWeb=(WebView)findViewById(R.id.apk_web);WebSettingswebSettings=apkWeb.getSettings();webSettings.setJavaScriptEnabled(true);StringapkUrl="/apk/demos/main/index.html#home";apkWeb.loadUrl(apkUrl);}}package com.tutor.apkinstaller;import android.app.Activity;import android.os.Bundle;import android.webkit.WebSettings;import android.webkit.WebView;public class ApkInstaller extends Activity { private WebView apkWeb; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(yout.main); apkWeb = (WebView)findViewById(R.id.apk_web); WebSettings webSettings = apkWeb.getSettings(); webSettings.setJavaScriptEnabled(true); String apkUrl = "/apk/demos/main/index.html#home"; apkWeb.loadUrl(apkUrl); }}

一、前言：
大家好，今天给大家分享一下Android中的拿来主义，我们时常会碰到一个自己觉得很漂亮很帅气的应用(apk),所以我们会尝试用WinRAR等之类工具查看，而一般的应用程序打包后的目录通常是这样的如下图：
当然res里的图片是可以拿来就用的(笔者的好多应用的图片都是从别人的apk里扣出来的)，而诸如layout里的布局及权限文件(AndroidManifest.xml)已经是一堆乱码了，完全看不懂，想看看别人是怎么布局的都不容易。还有源代码都被编译成了classes.dex，完全看不出什么线索。基于以上的困惑，笔者给大家分享一下Android中的拿来主义。
为了便于大家更容易程序比对，作者写了一个简单的应用(叫APKInstaller)目录结构如下图所示:
四、开始拿来主义
1.用AXMLPrinter2.jar查看apk中的布局xml文件:
将ApkInstaller应用生成的ApkInstaller.apk(为了方便起见放到tools目录里)用WinRAR等工具打开，将res/layout/main.xml解压出来(也还是放在tools目录里哦)
