Decompilation method in Android

Hypothetical testdecompile.apk

Method 1: Use dexdump for decompilation

Tool address: androidsdk/platform-tools/dexdump

Decompress testdecompile.apk first

Get a clip named testdecompile.apk _ files, which contains a classes. Dex file.

It is worth noting that classes. Dex is a Java bytecode file generated after Java source code compilation.

Run the command: dexdump classes. Dex, but this result cannot be viewed. So there are the following methods.

Method 2: Special Tools

Tool 1: dex2jar
Introduction: tools used to decompile Dex files into jar files
Address: http://code.google.com/p/dex2jar/

Tool: jdgui
Introduction: decompiling jar into a Java Tool
Address: https://java.decompiler.free.fr /? Q = jdgui

Decompress the downloaded file.

After dex2jar is decompressed, dex2jar. Sh (in Linux) in the folder converts classes. Dex to A. jar file.

Command:./dex2jar. Sh ../testdecompile.apk _ FILES/classes. Dex

You can get the classes_dex2jar.jar file.

Open the jd-Gui file in the folder after the jdgui is decompressed, and then open classes_dex2jar.jar and you will be OK...

Even though the decompilation of the .apk file is so simple, we need to confuse the Code. In the next article, I will summarize it again...
