Attaching frida tutorial

This tutorial explains how to attach a Frida script to Brawl Stars. Frida is a dynamic instrumentation toolkit that lets you inject scripts into running processes.

NOTE: MT Manager does not decompile dex files use something like apktool.

Steps:

Copy the Frida script:
- Place your Frida script into the /lib/arch/ directory within the APK. Replace arch with the appropriate architecture (eg. armabi-v7 or armabi-v8)
- Name the script libXXX.script.so, where XXX can be any name (e.g., libdebug.script.so).
Create a configuration file:
- In the same directory as frida script, create a configuration file named libXXX.config.so (e.g., libdebug.config.so).
- This file should contain the following JSON content, which tells Frida how to interact with the script:
```
{
    "interaction": {
        "type":"script",
        "path":"libXXX.script.so",
        "on_change":"reload"
    }
}
```
Add frida gadget:
- Download Frida gadget
- Place it inside of libXXX.so.
Modify the application’s Smali code:

Offline
- Open the smali/com/supercell/titan/GameApp.smali file.
- Locate the line containing "g".
- Move below the invoke of whatever offline script you have with anticheat kill.
- Insert the following Smali code to load your Frida script:
```
const-string lib, "XXX"
invoke-static {lib}, Ljava/lang/System;->loadLibrary(Ljava/lang/String;)V
```
  Replace "XXX" with the name you used in step 1 (e.g., "debug").
BSD
- Open the smali/com/supercell/titan/TitanApplication.smali file.
- Locate the line containing "BSD".
- Move below the invoke.
- Insert the following Smali code to load your Frida script:
```
const-string lib, "XXX"
invoke-static {lib}, Ljava/lang/System;->loadLibrary(Ljava/lang/String;)V
```
