WARNING: THIS TEMPLATE IS NOT FOR BEGINNERS. YOU NEED THE PROGRAMMING KNOWLEDGE, OTHERWISE THIS TEMPLATE WILL BE TOO HARD FOR YOU

This won't cover how to mod games in general, hooking functions, etc that every other online tutorial already covers. This template simply tells you how to use them

For Android mobile users who don't have a PC, please read README-MOBILE.md

Introduction

Floating mod menu for il2cpp and other native android games, based on VanHoevenTRs, and some codes used by Octowolve like animation. KittyMemory, MSHook, And64InlineHook and AY Obfuscator included. Assets are stored as base64 in cpp and does not need to be stored under assets folder.

It support Android 4.4.x way up to Android S Preview. Support ARMv7, x86 and ARM64 architecture. However x86 is deprecated for Unity games so x86 is not our priority

Preview:

Prerequisites

Before we can jump head first into working a template, we need to go over a few things.

AN EXPERIENCED MODDER, NOT A BEGINNER: You should be able to mod any games in general (does not need to be a protected games), like modifying .so files, dll files, smali files, etc.
Basic knowledge of smali dalvik opcodes to modify smali
Basic knowledge ARM and ARM64 assembly (x86 optional)
Basic knowledge of C++ and java
Be able to hook function in C++ (Not really needed, but recommended if you want to do advanced modding in the future)
Basic awareness of how Android layout works in XML and Java. This project only uses Java for layout but you will learn it easly
Time and patience: Don't start working on this if you have deadlines or important work. Take your time to read, learn and get used to work with this project.
DIY (Do it yourself): Yes, you must be able to do things yourself, not depending being spoonfeed. We don't spoonfeed, We are not the teachers.
An inquisitive mind

Softwares you need

Android Studio 4 and up: https://developer.android.com/studio
Apktool: Apktool.jar or any 3rd party tools
APK Easy Tool. To get main activity:
Any text editor. We use Notepad++

Setting up Android Studio

1. Installing NDK

At the bottom-right corner, click on Configure and SDK Manager

Select Android SDK, check NDK (Side by side) and click OK. It will download and install

2. Open the project

Extract the template project to the folder without any spaces. If any folder has spaces, it will cause problem

On the welcome screen, choose "Open an existing Android Studio project"

Navigate to the extracted project and open it

It will index and Gradle will sync the project fir the first time. Please wait for a while, it will take around 5 minutes depending your computer performance

If you encounter an error

NDK not configured. Download it with SDK manager. Preferred NDK version is 'xx.x.xxxxxx'

Click File and Project Structure

Select default NDK version

After it's done, you can start working!

Files to work with and making changes

Java

modmenu/Logcat.java: To save and clear logcat on menu settings without root and without file permission. Can be helpful for modders to diagnose the issues

Android 11: /storage/emulated/0/Documents/Mod Menu logs/

Android 10 and below: /storage/emulated/0/Android/data/(package name)/files/Mod Menu logs

modmenu/Preferences.java: Saving the menu feature preferences and calling changes via JNI

modmenu/FloatingModMenuService.java: Main codes of mod menu design

The codes of floating mod menu. You don't need to change much unless you want to redesign it. The codes are explained in the comments

GradientDrawable: A code for setting corner and stroke/inner border. Works for any View Components

GradientDrawable gradientdrawable = new GradientDrawable();
gradientdrawable.setCornerRadius(20); //Set corner
gradientdrawable.setColor(Color.parseColor("#1C2A35")); //Set background color
gradientdrawable.setStroke(1, Color.parseColor("#32cb00")); //Set border

Set the gradient drawable to the view component

[name of your view component].setBackground(gradientdrawable);

Resizing menu box

I've added variables so you can find it easly to resize

private final int MENU_WIDTH = 290;
private final int MENU_HEIGHT = 200;

Note: You may need to implement auto sizing due to many types of phone with different DPIs and resolutions

Color Animation: The codes can be seen in startAnimation()
Adding new view

Normally the Android development documentation does not explain the code in java. If you read the Android development documentation and you see an example like TextView

TextView textView = (TextView) findViewById(R.id.textView);
textView.setFontVariationSettings("'wdth' 150");

This is for xml. Instead, create an instance for java and add view to your Layout

TextView textView = new TextView(this);
textView.setFontVariationSettings("'wdth' 150");
LinearLayoutExample.addView(textView);

While we can't explain much here, you can use Google. Search like create a textview programmatically android, create a button programmatically android etc. for more infomation

MainActivity.java: Activity launcher. Checks if device running Android 6.0 or above and if have overlay permission enabled before starting menu service.

You pretty don't need to work with it unless you are implementing something like login layout.

Cpp

Menu.h: Menu related with JNI calls
Title: Big text
Heading: Little text. Semi HTML is supported. Text will scroll if the text is too long
Icon: Compressed image that is encoded to base64

You can pretty much use any tools for base64 encoding.

We use a simple website https://www.base64encode.org/

Scroll down till you see Encode files into Base64 format. Click or tap on the box to select a file

Click on ENCODE button and click on CLICK OR TAP HERE to download your encoded file. Now you can paste it in cpp code

IconWebViewData: Use icon in Web view with GIF animation support. URL requires internet permission android.permission.INTERNET

Examples

return env->NewStringUTF("https://i.imgur.com/SujJ85j.gif"); 

From assets folder: (Requires android.permission.INTERNET)
return env->NewStringUTF("file:///android_asset/example.gif"); 

Base64 html:
return env->NewStringUTF("data:image/png;base64, <encoded base64 here>");

Nothing:
return NULL

Main.cpp: In this file, you will work with your mods here

Changes: Get values to apply mods. BE CAREFUL NOT TO ACCIDENTLY REMOVE break;
settingsList: Settings assigned in negative numbers, we keep the positive numbers for mods. Works same as mod features but the call must be implemented in localChanges(int featureNum, boolean toggle) in FloatingModMenuService.java
getFeatureList: Mod features

Assigning feature numbers is optional. Without it, it will automatically count for you, starting from 0

Assigned feature numbers can be like any numbers 1,3,200,10... instead in order 0,1,2,3,4,5...

Do not change or translate the first text unless you know what you are doing

Toggle, ButtonOnOff and Checkbox can be switched on by default, if you add True_. Example: CheckBox_True_The Check Box

To learn HTML, go to this page: https://www.w3schools.com/

Usage:

(Optional feature number)_Toggle_(feature name)
(Optional feature number)_SeekBar_(feature name)_(min value)_(max value)
(Optional feature number)_Spinner_(feature name)_(Items e.g. item1,item2,item3)
(Optional feature number)_Button_(feature name)
(Optional feature number)_ButtonOnOff_(feature name)
(Optional feature number)_InputValue_(feature name)
(Optional feature number)_CheckBox_(feature name)
(Optional feature number)_RadioButton_(feature name)_(Items e.g. radio1,radio2,radio3)
RichTextView_(Text with limited HTML support)
RichWebView_(Full HTML support)
ButtonLink_(feature name)_(URL/Link here)
Category_(text)

Examples

10_Toggle_Jump hack
100_Toggle_Ammo hack
Toggle_Ammo hack
1_Spinner_Weapons_AK47,9mm,Knife
Spinner_Weapons_AK47,9mm,Knife
2_ButtonOnOff_God mode
Category_Hello world

Learn more about HTML https://www.w3schools.com/

hack_thread: Here you add your code for hacking with KittyMemory or Hooking. We will not teach, you must have learned it already

KittyMemory usage:

[Struct].get_CurrBytes().Modify();
[Struct].get_CurrBytes().Restore();

[Struct].get_TargetAddress();
[Struct].get_PatchSize();
[Struct].get_CurrBytes().c_str();

Example: https://github.com/MJx0/KittyMemory/blob/master/Android/test/src/main.cpp

Use ARM Converter to convert ARM to HEX: https://armconverter.com/

Hook usage: ARM64: A64HookFunction((void *) getAbsoluteAddress([Lib Name], [offset]), (void *)[function], (void **)&[old function]);

ARMv7/x86: MSHookFunction((void *) getAbsoluteAddress([Lib Name], [offset]), (void *)[function], (void **)&[old function]);

Android.mk

The make file for the c++ compiler. In that file, you can change the lib name on the LOCAL_MODULE line When you change the lib name, change also on System.loadLibrary("") under OnCreate method on MainActivity.java Both must have same name

C++ string obfuscation

We use AY Obfuscator but the usage has changed to OBFUSCATE("string here") and OBFUSCATE_KEY("string here", 'single letter here')

Example

OBFUSCATE("Hello world")
OBFUSCATE_KEY("Hello world", 'a')
OBFUSCATE_KEY("Hello world", 'u')

Testing

Connect your device to the computer or run your emulator. Android Studio will detect and you can click Play to run your app.

On physical device, make sure you have USB-Debugging enabled in the developer option of your device. To make it visible, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options at the bottom. The Developer options screen might be located or named differently on some devices

Sometimes Android Studio does not detect emulators such as NOX or MEMU fail to connect to adb automatically, reboot can help sometimes. Please refer to the support page.

Implementing the menu to the target game

1. Know your game's main activity

Now we are looking for main activity, there are 2 ways to do

Decompile the game's APK file. Open AndroidManifest.xml and search after <action android:name="android.intent.action.MAIN"/>.

Example the game's main activity was com.unity3d.player.UnityPlayerActivity

Be sure to enable Word wrap so it is easier to read

APK Easy Tool since it can read out location of main activity without decompiling APK

Note it somewhere to remember it

2. Making corresponding changes in the files

Decompile the game APK

Open the game's AndroidManifest.xml

Add the SYSTEM_ALERT_WINDOW permission besides other permissions if it doesn't exist. Doesn't matter where you place it as long as it's above the application tag

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

If you don't add it, you can't allow overlay permission.

Add the service above the end of application tag (change the package name of your menu if you had changed it)

<service android:name="uk.lgl.modmenu.FloatingModMenuService" android:enabled="true" android:exported="false" android:stopWithTask="true"/>

Now we need to call your mod menu activity

There are 2 ways to call your mod menu activity. Choose one of them you like to try. Don't know? just choose METHOD 1

METHOD 1

This simple way, we will call to MainActivity.java. MainActivity.java will never be used

Locate to the game's path of main activity and open the smali file. If the game have multi dexes, it may be located in smali_classes2.. please check all

With the path of the target game’s main activity which we determined earlier com.unity3d.player.UnityPlayerActivity. Think of it like a path /com/unity3d/player/UnityPlayerActivity.smali

Open the main acitivity's smali file, search for OnCreate method and paste this code inside (change the package name if you had changed it)

invoke-static {p0}, Luk/lgl/MainActivity;->Start(Landroid/content/Context;)V

Save the file

METHOD 2

You can follow this it if the first method really fails, or if you really want to use MainActivity.java for a reason. Since this involve changing activites, it may cause some problems.

On your MainActivity.java, put the game's main activity to public String GameActivity

Uncomment this code

Toast.makeText(MainActivity.this, "Error. Game's main activity does not exist", Toast.LENGTH_LONG).show();

On AndroidManifest.xml, remove <action android:name="android.intent.action.MAIN"/> from the game's activity, like this:

If you don't remove <action android:name="android.intent.action.MAIN"/> from the game's activity, your menu will not launch. AndroidManifest.xml can ONLY contain one <action android:name="android.intent.action.MAIN"/>

near the end of application tag </application>, add your main activity above it. uk.lgl.MainActivity is your main activity

<activity android:configChanges="keyboardHidden|orientation|screenSize" android:name="uk.lgl.MainActivity">
     <intent-filter>
         <action android:name="android.intent.action.MAIN"/>
         <category android:name="android.intent.category.LAUNCHER"/>
     </intent-filter>
</activity>

Save the file

Do NOT use both methods at the same time

3. Building your project and copying files

Build the project to the APK file. Build -> Build Bundle(s)/APK(s) -> Build APK(s)

If no errors occured, you did everything right and build will succeded. You will be notified that it build successfully

Click on locate to show you the location of build.apk. It is stored at (your-project)\app\build\outputs\apk\app-debug.apk

Decompile your app-debug.apk.

Copy your mod menu from decompiled app-debug.apk smali to the game's smali folder. Example ours is uk.lgl.modmenu, we copy the uk folder from app-debug (app-debug\smali\uk) to the game's decompiled directory (game name)\smali

If the game have multidexes, just add your smali to the last smali_classes if possible to prevent compilation errors such as Unsigned short value out of range: xxxxx (Smali limit error)

Copy the library file (.so) from app-debug.apk to the target game. Watch out the folder names, we don't want to mix them up, so make sure to copy our lib file to the correct architecture. Like our armeabi-v7a lib goes to the target games armeabi-v7a folder, arm64-v8a lib goes to the arm64-v8a folder...

PUTTING THE LIB FILE ON A WRONG ARCHITECTURE LIKE PUTTING ARM64 LIB TO ARMV7 WILL RESULT A CRASH!

4. Compiling game apk

Now compile and sign the apk, and install it on your device

Congrats. You have successfully implemented a mod menu.

Compile failed? read the log and look up on Google

If you face any problem, please read the FAQ

Loading lib without mod menu

Just comment out or remove the code that checks for Overlay permission in MainActivity.java and loads. No need to remove any menu related from cpp

FAQ

My game crashing or freezing/My mod menu does not work

There are many reasons why, it could be your code fault, wrong offsets, bad c++ code, bad layout implementations, game protections etc.

First of all, check logcat on Android Studio to see the error logs. Connect your device/reboot emulator to reconnect, open Logcat window from below, and select your device, process and filter to Error and reproduce your problem. Once you do, you can see the errors in logcat

Or you can save logcat to file via mod menu settings

Then read logcat and figure out yourself. Google it if possible.

If the game crashes or freezing while playing, check if your patches and hooks are correct. For hooks, write down the logs such as LOGD("whatever"); like this below:

bool get_BoolExample(void *instance) {
    LOGD("BoolExample 1");
    if (instance != NULL && featureHookToggle) {
        LOGD("BoolExample 2");
        return true;
    }
    LOGD("BoolExample 3");
    return old_get_BoolExample(instance);
}

Recompile and check the logcat, to see what part of your code faced the problem.

Logcat may also report CRASH if lib crashed, caused by hooking

See more about logcat: https://developer.android.com/studio/debug/am-logcat

If you believe the game has protection, bypass it or drop it

I have a problem decompiling or compiling APK file

Search for the related issues on Google or on Apktool Github page: https://github.com/iBotPeaches/Apktool/issues

I'm getting an error `Unsigned short value out of range: 65536` if I compile

The method index can't fit into an unsigned 16-bit value, means you have too many methods in the smali due to the limit 65535. Place your code on other classes, such as smali_classes2 instead. This work for Android 5 (Lollipop) and above only.

I'm getting an error `ERROR: executing external native build for ndkBuild Android.mk. Affected Modules: app`

See: https://github.com/LGLTeam/Android-Studio-Solutions/wiki/Executing-external-native-build-for-ndkBuild-Android.mk

I'm getting strange issues on Android Studio or Gradle

See: https://github.com/LGLTeam/Android-Studio-Solutions/wiki

How can I protect my dex and/or lib?

There is no need to protect dex since there are nothing important in java/smali codes. Offsets and strings are protected enough. We do not recommended to use chinese tools as anti virus may flag your mod for malware (false positive). Don't ask us for the tools

How to get older version of the template? or how to see updates/commits?

Go to the commit page https://github.com/LGLTeam/Android-Mod-Menu/commits/master

Why can't you just add the feature I want? For example closing animation?

Also known as: "You're a developer after all — it shouldn't be that hard!"

Since I can't spend my days on it, I have to prioritize the features and fixes that are likely to benefit the larger number of people. Features that is specific to your usage is not going to benefit that many users after all. This is important that you do not expect that I can do everything for you. Developing is hard, and even outside of supporting a feature, adding the code can take longer than you think!

With all this being said, remember that this is 100% Open Source. So if you really want a specific feature, try to do it yourself, or ask someone who are willing to help you.

Why can't you just teach me modding the game? For example, hooking or making aimbot and ESP?

We aren't spoonfeeding. Anything else, such as how to hook, how to patch, how to bypass shitty PUBG, what functions to mod, how il2cpp works, etc. is out of scope. We will not cover anything and trivial stuff every other tutorial online already covers. Instead, try to find a couple of tutorials to learn and mod the game yourself. It's a lot easier than you think. If you can't, find a couple of forums where you can ask your questions. If you saw someone modded the game which has special feature like floating text seen on Among US, ask the right owner. Move on if they don't want to help you!

Reporting issues/Cоntact

Please stop and read this carefully.

Make sure you have readed FAQ and at least searching for answers.

If you have usage problems, try asking your questions on any forum sites. For example, if you have an issue with hooking or patching, bypassing PUBG, or you don't know how to put this menu in APK, you should go to the forums. Here there are no teachers, or who deal with issues or spoonfeeding.

Beginner/newbie/noobs are NOT allowed to cоntact. They are often annoying, which is the reason we no longer accept. You will be left unanswered. Experienced modders can contact as they want, as long as they are not annoying.
