DroidCarve

DroidCarve is capable of analyzing an Android APK file and automate certain reverse engineering tasks. This repository contains the server and client component.

The Frontend

The frontend is a React application, which you can find in the client/ subfolder.

The Backend

The backend is a Python flask application, which you can find in the server/ subfolder.

Installation

Automatic

Installation files only work on OS X for now, but DroidCarve should still run fine on Linux, for installation see Manual section.

git clone https://github.com/DarioI/droidcarve
cd droidcarve
chmod +x install.sh
chmod +x run.sh
./install.sh
./run.sh

Manual

Make sure you have Python 3.4+ installed.

• Install the JS dependency management tool Yarn.
• Install the Android Debug Bridge (ADB) tool.
• Clone the DroidCarve repository

git clone https://github.com/DarioI/droidcarve

cd droidcarve/client
yarn install
yarn build

• Install the Python dependencies

cd ../server
source venv/bin/activate
pip install --upgrade pip
pip install --no-cache-dir -r server/requirements.txt
