I am currently using the Xamarin geolocation plugin found here:
https://github.com/jamesmontemagno/GeolocatorPlugin
To run location services in an application, I create using Xamarin Forms (PCL). I believe that I added permissions to the appropriate settings to allow this.
GPS works great when the application is active and locked (but with the application in the foreground). However, when the application moves to the background on iOS by pressing the home button, it still tracks the user and displays the message “The application is using your location,” as I expected, but after a while between 30-40 minutes, this message disappears , and GPS appears to stop user tracking until they bring the app back to the forefront.
After the application has been brought to the forefront, it can be re-created again within 30-40 minutes to repeat the cycle.
I guaranteed that the locator object allows background updates:
public static Plugin.Geolocator.Abstractions.IGeolocator locator; locator = CrossGeolocator.Current; locator.AllowsBackgroundUpdates = true; locator.DesiredAccuracy = 20;
Calling .PausesLocationUpdatesAutomatically indicates that it is a lie (in my opinion, this is the default value).
Edit
I have the following keys for info.plist:
NSLocationWhenInUseUsageDescription NSLocationAlwaysUsageDescription
Activated background location updates:
However, I did not enable background extraction, since Girish has the answers, is this something I need to do?
