This project was developed as part of the SE2: Software Design and Architecture - CS 446, CS 646, ECE 452 course offered at the University of Waterloo. This is not an individual project, but rather a group effort. Each member has contributed to various aspects of the project development.

SingleStep is an AI powered trip-planning app that leverages OPEN AI's GPT3.5-Turbo model to craft personalized day-by-day trip itineraries. It also allows users to seamlessly search for flights, hotels, and nearby tourist attractions.

• Glide - Used for loading and caching images for destinations, hotels etc.
• Retrofit - Used for making API GET requests to fetch hotels and itinerary response
• RoomDB - Used for storing saved trip itineraries for offline viewing
• Amadeus Android SDK - Used to fetch airports, flights and local tourist attractions
• Google Places SDK - Used to fetch city data and autocomplete city names
• Facebook Shimmer - Used for loading animations throughout the application
• Jsoup - Used to parse HTML description for tourist attractions into text

• Amadeus API - Used the following endpoints for multiple features:

  • shopping/activities - Used to fetch local tourist attractions
  • shopping/flightOffersSearch - Used to fetch flights for given input trip parameters
  • referenceData/locations/airports - Used to fetch airport IATA codes for given set of coordinates

• Booking.COM Scraper API - Used the stays/search-by-geo endpoint to fetch hotels for given input trip parameters

• Google Places API - Used for autocompleting source and destination city name on the Search page

• OpenAI API GPT3.5 Model - Used for generating day-by-day intinerary for given input trip parameters, selected hotel and flights

To run the backend server, simply attach your OPEN AI API Key in the backend/prompt/inference.py file and run the following command:

python3 .\backend\app.py

Then, ensure that your API keys for Google Places API, Amadeus API, and Booking.com API are configured correctly inside the app/res/values/strings.xml file.

<string name="places_api_key">YOUR_API_KEY_HERE</string>
<string name="amadeus_api_key">YOUR_API_KEY_HERE</string>
<string name="amadeus_api_secret">YOUR_API_SECRET_HERE</string>
<string name="booking_api_key">YOUR_API_KEY_HERE</string>
<string name="booking_api_host">booking-com18.p.rapidapi.com</string>
