PineHookPlus

PineHookPlus is an advanced example project demonstrating creative and efficient ways to leverage the Pine Hooking Framework for runtime modifications in Android apps. This project focuses on simplifying the integration and customization of hooks, offering a structured and flexible approach to app behavior modification.

🌟 Features

• Automatically loads libraries based on the user's system architecture:
  • AArch64 (arm64) and armeabi-v7a architectures supported.
  • A11 and UP.
• Libraries are stored in the root directory of the APK under hook/ for streamlined access.
• Use config.json to define hooks in the hook/ directory.
• Easily specify:
  • Class Name: Target class to hook.
  • Method Name: Method to override.
  • Parameter Types: Types of parameters accepted by the method.
  • args: Arguments to pass to the hooked method.
  • Return Value: The desired return value of the hooked method.
• No need to write or compile custom code for every method.
• Directly hook into and modify class constructors.
• Moves away from methods like AppComponentFactory, android:name and uses ContentProvider.

📋 Example Configurations

Hooking a Method

In config.json, define the target class and method to hook, along with the parameter types, arguments, and return value as needed:

{
  // Target class to hook
     "com.pinehook.plus.MainActivity": {
        // Method name to hook
        "argMethod": {
            // parameter types of the method
            "paramTypes": [
                "boolean"
            ],
            // return result of the method after it's call
            "after": {
                "result": false
            }
        },
        "beforeOnlyMethod": {
            "paramTypes": [
                "java.lang.String"
            ],
            "before": {
                 // args to pass to the method before it's call
                "args": [
                    "modifiedBefore"
                ]
            }
        },
        "afterOnlyMethod": {
            "paramTypes": [
                "java.lang.String"
            ],
            "after": {
                 // return result of the method after it's call
                "result": "modifiedAfter"
            }
        }
    },
}

Hooking a Constructor

{
  // Constructor hook example
    "com.pinehook.plus.ConstructorClass": {
        // Do not change this value for constructor hook
        "constructor": {
             // parameter types of the constructor
            "paramTypes": [
                "boolean",
                "java.lang.String",
                "boolean",
                "long",
                "long",
                "java.lang.String",
                "java.lang.String",
                "java.lang.String"
            ],
             // args to pass to the constructor before it's call
            "before": {
                "args": [
                    true,
                    "PlayStore",
                    false,
                    0,
                    0,
                    "null",
                    "Yearly",
                    "null"
                ]
            }
        }
    }
}
