Task 1: Backend Development

A Flask-based REST API was developed to manage app details in a database.

Endpoints:

1. POST /add-app - Adds an app to the database.
2. GET /get-app/{id} - Retrieves app details by ID.
3. DELETE /delete-app/{id} - Removes an app by ID.

Task 2: Database Management

• SQLite was used as the database to store app details.
• Flask-SQLAlchemy was used to manage the database.
• The database stores app details with fields: app_name, version, and description.

---

Task 3: Virtual Android System Simulation

A Python script simulates a virtual Android system capable of:

1. Launching a virtual Android environment.
2. Installing a sample app (sample_app.apk).
3. Retrieving and logging system information (OS version, device model, available memory).

---

Task 4: Basic Networking

• A Python script was created to establish an HTTP connection with the backend server.
• It sends mock data (device ID, system info) to the Flask API.
• The server's response is logged.

Setup and Installation

Prerequisites

Ensure you have Python 3 installed on your system.

Install Dependencies

Run the following command:

pip install -r requirements.txt

Running the API

python app.py

The API will be available at http://127.0.0.1:5000/.

Running the Virtual Android System

python virtual_android.py

Running the Networking Script

python networking.py

---

Testing the API

You can test the API using tools like Postman or curl commands.

Add an App

curl -X POST http://127.0.0.1:5000/add-app -H "Content-Type: application/json" -d '{"app_name": "TestApp", "version": "1.0", "description": "Sample application"}'

Retrieve an App

curl -X GET http://127.0.0.1:5000/get-app/1

Delete an App

curl -X DELETE http://127.0.0.1:5000/delete-app/1
