Uber Like Android App

Building a ride-sharing Android Taxi Clone App like Uber

About me

Hi, I am Nimisha Kumari, currently working on building Uber like ridesharing app using Beckn Protocol. .

following for the App:

• Create Rider Android Clone App
• Fetch and show nearby cabs on Google Map
• Set Pickup and drop location
• Book a cab
• Fetch and show driver current location
• Show pickup and trip path on Map with Animation
• Cab Arrival for a pickup like Uber
• On-going trip UI
• Trip End
• Animation like Uber App for Moving Car
• Just to make it simple. This project uses the basic MVP Architecture for building the Uber and Lyft clone
• We have simulated the WebSocket API for you

local.properties will like below:

sdk.dir=PATH_TO_ANDROID_SDK_ON_YOUR_LOCAL_MACHINE    
apiKey=YOUR_API_KEY

• Start implementing features:
  • Start with a new project.
  • Setup project with basic MVP Architecture.
  • Implement Permission for fetching current location.
  • Implement feature - nearby cabs.
  • Use WebSocket present in simulator module to fetch the nearby cabs.
  • Implement feature - pickup and drop location.
  • Implement feature - book a cab.
  • Implement feature - Show pickup path on the map with Animation.
  • Implement feature - Show the current driver location during pickup.
  • Implement feature - Cab is arriving and arrived.
  • Implement feature - Car Animation like Uber.
  • Implement feature - Show trip path on the map with Animation.
  • Implement feature - Trip Starts.
  • Implement feature - Show the current driver location during the trip.
  • Implement feature - Trip on-going.
  • Implement feature - Trip Ends.
  • Implement feature - Implement Take Next Ride.

WebSocket API Reference for this project

A WebSocket is a persistent connection between a client and server. WebSockets provide a bidirectional, full-duplex communications channel that operates over HTTP through a single TCP/IP socket connection. At its core, the WebSocket protocol facilitates message passing between a client and server. In our case, we have simulated it for you.

• In WebSocket, we have three methods:

  • connect(): To connect with the server
  • sendMessage(data: String): To send the data to the server
  • disconnect(): To disconnect from the server

• In WebSocketListener, we have four callbacks:

  • onConnect(): Called when it is connected with the server
  • onMessage(data: String): Called when an event comes from the server
  • fun onDisconnect(): Called when the client is disconnected from the server
  • fun onError(error: String): Called when the error occurred on the server

• Client sending event to server using webSocket.sendMessage(data):

  • Request for nearby cabs from server

  {
    "type": "nearByCabs",
    "lat": 28.438147,
    "lng": 77.0994446
  }

  • Request a cab from server
