All mobile phone platforms have access to core location services. These services are background tasks that run in the background and update the latitude and longitude values at certain intervals indefinitely until the service is stopped. 99% of smart phones come with a built-in GPS tracker, allowing you to integrate these latitude and longitude values with your application.
Let's jump straight into project setup and create a new Xamarin.Forms application. We are going to start by setting up an IoC container with Autofac, exactly the same as the previous project, import Autofac into all three projects (PCL, Android, and iOS). We can reuse a lot of the PCL code from the IoC container implementation in the previous project.
Note
The more apps you build, the more problems you solve; why reinvent the wheel over and over? Eventually, when you have built multiple applications, future apps will be built mostly from piecing parts of different projects together.
