FakerAndroid (FakerAndroid.jar or FakerAndroid-AS)

A tool translate a apk file to stantard android project include so hook api and il2cpp c++ scaffolding when apk is a unity il2cpp game.

Summary

• Write code on a apk file elegantly.
• The Apk file can be directly converted into Android project for secondary development, supporting so hook. For the game of il2cpp, APK directly generates il2cpp C++ scaffolding
• What's more to say about transforming the painful reverse environment into a comfortable development environment, saying goodbye to assembly and binary~

Feature

• Stantard AndroidStudio android project generated
• Original java class usage or cover it by compileable java code
• Hook Api offered for hooking .so method
• When apk is a il2cpp game il2cpp c++ scaffoding generated
• Back compilation voluntary when there is a modification of smali files(AndroidStudio project file tree model)
• Unlimited possibilities and expansibility. You has the final say

Environment

• Java(18)
• For Il2cpp Game Apk to generate il2cpp C++ scaffolding .Net environment needed (Mac&Linux users handle it by yourself)

Usage

• Download FakerAndroid.jar(2022/03/30/23:48:00)
• cmd cd <FakerAndroid.jar base dir>
• cmd java -jar FakerAndroid.jar fk <apkpath> (project will be generated in the same dir of the orininal apk) or java -jar FakerAndroid.jar fk <apkpath> -o <outdir>
• Demojava -jar FakerAndroid.jar fk D:\apk\test.apk or java -jar FakerAndroid.jar fk D:\apk\test.apk -o D:\test

Or Usage

• Download FakerAndroid-AS.zip(2022/03/30/23:48:00)
• AS->File-Settings->Plugin->SettingIcon->InstallPlugin Plugin From Disk->Restart As
• AS->File->FakerAndroid->Choose your apk file

Secondary development course

1、Open the project

• By Android studio File->open-><generated project root>
• Keep the root dir build.gradle file depends com.android.tools.build:gradle:3.4.0,don't upgrate or modify it
• Set project ndk base version 21 best
• A little modification will be needed by yourself when the res or AndroidManifest.xml can't pass the compiler

2、Debug or run the project

• With a testing machine conected
• Run

3、Advanced

• Original java class call
  With the help of javaScaffoding write your java code to call original class in app moudle(app/src/main/java)
• Original java class replacement
  Write java code in moudle app（app/src/main/java）,keep the class name and package name corresponding same as the original class
• Smali increament building
  When there is a smali files mod,there is a least files builing
• So Hook
  With the help of fakeCpp api use jni hook the so method
• Il2cpp unity script development
  With the help of il2cpp Scaffolding and fakeCpp api,use jni have a modification of il2cpp game script
