This archived guide provides a detailed tutorial on building an Uber or Lyft-like rideshare app using PubNub for real-time vehicle tracking on Android. The app distinguishes between driver and passenger roles, utilizing a publish/subscribe model to update and receive the driver's location every five seconds. Essential setup includes configuring Gradle dependencies for the PubNub Android SDK and Google Play Services, setting permissions, and obtaining API keys from Google's Developer API console. The MainActivity class directs user interfaces and manages PubNub connections, while DriverActivity handles location updates using the FusedLocationProviderClient and publishes them to a PubNub channel. PassengerActivity displays the driver's location on a MapView, updating in real-time through a SubscribeCallback. The tutorial emphasizes smooth animation of the driver's marker and suggests further enhancements, such as adding a feature for the marker to rotate with the vehicle's direction.
