Stitch

Stitch is a powerful APK patching python library that allows you to inject your own java module into any APK, bundle or XAPK file.

How it works

Will be added soon.

Projects using Stitch:

• WhatsAppPatcher- A patcher for WhatsApp Android app.
• MoovitPatcher- A patcher for Moovit app.
• MakoPatcher- A patcher for 12+ app.

How to use

Installation

You can install Stitch using pip:

# For now, install the test version from TestPyPI
pip install stitch

Basic Usage

Create an Android Gradle project like my smali_generator (Check it out in on of the examples) that generates the java module you want to inject.

Then, use the following code to patch an APK:

from stitch import Stitch
from stitch.common import ExternalModule
from pathlib import Path

with Stitch(
        apk_path='./input.apk',
        output_apk='./output.apk',
        external_modules=[ExternalModule(Path(__file__).parent / './smali_generator',
                                         'invoke-static {}, Lcom/smali_generator/TheAmazingPatch;->on_load()V')]
) as stitch:
    stitch.patch()

And that's it! Your APK will be patched with the injected module.
