An introduction to the Android Anti-compilation tool and a simple and practical approach

The purpose of Android anti-compilation is simply to see the APK's XML, Resources and code:

How to get the code: Extract the APK file directly--get Classes.dex file--and use Dex2jar classes.dex Classes.jar generate Jar file--[optional extract jar file]-- View source code using Xjad or Jdcompiler

How to get the xml:

Mode 1: Unzip the APK file directly--and view the XML file with the Axmlprinter tool (this way the ID of the XML file is a number-the value corresponding to the ID in the R file)

Method 2: Unzip the apk file using the Apktool tool to view the XML file directly

Android Anti-compilation often uses some of the following tools:

1. Anti-compile command:

Apktool D d:\\developer\androiddecode\test0201.apk d:\\developer\androiddecode\test0201

D:\\DEVELOPER\ANDROIDDECODE\TEST0201.APK: apk file to Decompile

d:\\developer\androiddecode\test0201: The Save directory for the anti-compilation file must be an empty directory

2, compiled from the anti-compilation file apk apktool b d:\\developer\androiddecode\test0201 d:\\developer\androiddecode\test020101.apk

D:\\DEVELOPER\ANDROIDDECODE\TEST0201: Save the compiled file directory

D:\\DEVELOPER\ANDROIDDECODE\TEST020101.APK: The absolute path to save the generated new APK file

3. Signature APK file:

Singedapk.bat file

Java-jar "%~dp0signapk.jar" "%~dp0testkey.x509.pem" "%~dp0testkey.pk8"%1 signed.apk

Execute Singedapk.bat command

singedapk d:\\developer\androiddecode\test020101.apk generate a singed.apk file and test020101.apk in the same directory

4. Use Baksmali.jar to convert a Dex file to a Smali file

Java-jar D:\\developer\apktool\baksmali.jar-o d:\\developer\androiddecode\baksmaliout D:\\Developer\androidDecode \hello.dex

Full path to the D:\\developer\apktool\baksmali.jar:baksmali.jar file

D:\\developer\androiddecode\baksmaliout: Save directory for generated Smali files

D:\\developer\androiddecode\hello.dex: The path to be converted to the Smali file

5. Use Ddx.jar to convert a Dex file to a DDX file

Java-jar d:\\developer\apktool\ddx.jar-d d:\\developer\androiddecode\ddxout D:\\developer\androiddecode\hello.dex

Absolute path to the D:\\developer\apktool\ddx.jar:ddx.jar file

D:\\developer\androiddecode\ddxout: Path to save the DDX file

D:\\developer\androiddecode\hello.dex: The Dex path to convert

6. Android comes with Dexdump tool: Dex file to Smali file dexdump-d xxxx.dex > Xxxx.smali

7, Dex2jar.jar:dex2jar Xxx.dex Yyy.jar
