implementation group: 'com.pubnub', name: 'pubnub-gson', version: '4.12.0' Be sure that Google Play Services is installed from the Android SDK Manager on the tools portion of the menu, so we may implement the necessary libraries. In the adle file for the app module under dependencies, input the codeblock of command below to ensure that we have what we need. We also will implement libraries, in order to complete some basic JSON parsing of PubNub messages. We first need to write our Gradle dependencies to use the PubNub Android SDK and Google Play Services for the map functionality. This publish/subscribe model is displayed in the visual below. If a user is a passenger, they will subscribe to the same channel to receive updates on the current location of their driver. If a user is a driver, their current location will be published to a channel, updated every 5 seconds (in this sample), or however many times your app requires. The sample app we will build first asks the user if they are the driver or the passenger. In this tutorial, we’ll show you how to implement this common use case in an Android application. Building this functionality is challenging and can be tedious, but we’ll simplify it with an easy publish/subscribe model between the drivers and passengers, powered by PubNub.įull source code for this tutorial is available here. Tracking the real-time location of another device is the basis of many popular mobile, location-focused apps, especially when it comes to building taxi or rideshare apps like Lyft and Uber.
