Awiros: App-a-thon

Tech Stack

• Ai/ML: Python, OpenCV
• Mobile App: React Native + Expo
• Backend: Python, Firebase Database

How to setup project

Clone the repo

Fork the repo and then clone it using

git clone [email protected]:<YOUR_USERNAME>/awiros-appathon-mobile-app.git
cd awiros-appathon-mobile-app

Install dependencies

npm install
pip3 install pyrebase4 opencv-python numpy

Setup API keys

• Create a new Firebase project
• Create a new file process.env.json and add the following code:

{
    "API_KEY":"",
    "AUTH_DOMAIN":"",
    "DB_URL":"",
    "PROJ_ID":"",
    "STORAGE_BUCKET":"",
    "MESSAGING_SENDER_ID":"",
    "APP_ID":"",
    "MEASURMENT_ID":""
}

• Replace the values with your Firebase project's API keys
• You will need to install and login to the expo cli to run the app. Follow the instructions here
• You will also need a google-services.json file from Firebase. Download it and place it in /RNApp, then upload the file to eas secrets using the following command, as it will be ignored by the build.

eas secret:create --scope project --name GOOGLE_SERVICES_JSON --type file --value ./google-services.json

Running the app

Creating a development build

# For cloud build through EAS
eas build --profile development
# For local build
eas build --profile development --local

The dev build should be installed either on a real device or a simulator for development and live testing purposes. Every time new Native code is added to the project through expo or npm a new development build will have to be created and installed.

Creating a production build

# For cloud build through EAS
eas build --profile production
# For local build
eas build --profile production --local

Run the ML script

python3 cv.py

Now the counter on the app should increase if a person is detected in the frame.
