The Challenge of Changing Text in Android App lib.so

When modifying an Android app’s native library lib.so, one of the most common problems you face is this:

You want to replace a small string like "Hello" with a much longer one like "Welcome to Antik’s Mod"
But the original memory space for "Hello" is very limited so if you just overwrite it, the new text overflows into other data and crashes the program

How Text Is Stored

Strings like "Hello" aren’t stored directly inside the code.
Instead, the code holds a memory address (pointer) to where that text actually lives

Example :)

asm
LDR R0, =0x8334
BL printf

That means

“When showing the message, go read the string stored at address 0x8334.”

So, "Hello" is actually stored at lib location 0x8334

You can’t just write a longer string in the same place but you can redirect the program to another location with more space. This is called static patching

Find a New Home :)

Inside the .so file, you can often find large, unused or unimportant text areas called data caves a long help
message, debug string, or readme text that the app never uses Let’s say you find a big help text at

Offset : 0x7788 --> "App is Good app for You..."

This will be your new home for the custom text

Reroute the Pointer

In the original code

asm
LDR R0, =0x8334

Change that instruction so it points to your new offset

asm
LDR R0, =0x7788

Now the program will look for the string at 0x7788 instead of 0x8334

Open your so file in a hex editor and go to address 0x7788
Replace the old text (App is Good app...) with your new one

Welcome to Antik’s Mod

After your new string, you must add a null terminator (00) Example in hex

57 65 6C 63 6F 6D 65 20 74 6F 20 41 6E 74 69 6B 27 73 20 4D 6F 64 00

That final 00 tells the program

Alternative --> write replacement string to .rodata and use LineHook to redirect the existing pointer to the new location -- required c++ library <utf8.h>

How to Connect Weapon Class to Player Class Complete Guide

Weapon Class Explained

The Weapon class handles gun bullet count

class Weapon {
private:
int ammo; // Hidden variable

public:
// Setter method to change ammo
void setAmmo(int value) {
ammo = value;
}

// Getter method to read ammo
int getAmmo() const {
return ammo;
}
};
Player Class Connection

Player class contains weapon directly

class Player {
private:
Weapon weapon; // Player OWNS this weapon 0x2C

public:
// Returns weapon's address
Weapon* getWeapon() {
return &weapon;
}
};

Enemy Class Difference

class Enemy {
private:
Weapon* weapon; // Enemy has pointer to weapon 0x2C

public:
Weapon* getWeapon() const {
return weapon;
}
};
Hook Explain

void saferHookedUpdate(void* instance) {
// Check if this is Player (not Enemy)
if (IsPlayerInstance(instance)) {

// Extract weapon from memory offset 0x2C
void* weaponPtr = *(void**)((uint64_t)instance + 0x2C);

// If weapon exists, set ammo to 10000
if (weaponPtr != NULL) {
originalSetAmmo(weaponPtr, 10000);
}
}

// Call original game function
originalUpdate(instance);
}

How It Works In Game

Game updates all characters update each frame CPM Our hook intercepts runs before original update function Checks instance type identifies player vs enemy Sets unlimited ammo only for players 10000 bullets Game continues resumes normal operation

     void* Weapon = *(void**)((uint64_t)instance + 0x1D0);
     
     
     if (Weapon != NULL) {
   
    if (isZoom > 0) {
    *(float *) ((uint64_t) Weapon + 0x1dc) = (float) isZoom;
   }
   
  }
    }
    return orig_updateStepP(instance, f1, v1, v2, f2);
}

Some people still don't know about the field Offset I explain 😂👏 See

Example '*

Your update offset is 0x7788.

Your field offset

float get_speed is 0x5

That means the full field address is 0x7788 + 0x5
For example, in hex: 00 66 55 66 C7 88
here C7 is the pointer of your field

Lib Diff Tool Lightweight library comparer for modding

A simple and fast tool to compare native libraries and other files when an APK is modded but the DEX isn't changed. Works well with large libraries (1GB+) If you have the original library and a modded one, this tool highlights differences so you can quickly find what was changed.

Dialog interceptor & killer also kill specific dialogue 😂🪄

What class are accessing this show method 😂

AantikToast – C++ Toast Without Any JNI Methods

AantikToast() is a simple and elegant C++ function that lets you show Android Toast messages directly from native code no extra Java methods, no messy JNI bridges, and no unnecessary boilerplate It works smoothly with just JNIEnv* and a jobject context.

And yeah… some people tried to use this same context to show dialogs 😂

+ Java developer understand this point ---[]

But listen Android has many different types of contexts and this one is ONLY meant for showing Toasts. Don’t try anything else with it
