Let’s start,

Step 1 - Open Visual Studio, New Project, Templates, Visual C#, Android, then select Blank App (Android)

Select Blank App, then give Project Name and Project Location.



Step 2

Next go to Solution Explorer, Project Name, Properties, then AndroidManifest.xml to open the Code page. Then give permission for Network and Location services.

XML Code

  1. <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
  3. <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
  5. <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Step 3 - Next to open Solution Explorer, Project Name, then MainActivity.cs open and write the following C# Code.

C# Code

  1. using System;
  2. using Android.App;
  3. using Android.Content;
  4. using Android.Runtime;
  5. using Android.Views;
  6. using Android.Widget;
  7. using Android.OS;
  8. using Android.Locations;
  9. namespace CheckNetwork
  10. {
  11. [Activity(Label = "CheckNetwork", MainLauncher = true, Icon = "@drawable/icon")]
  12. public class MainActivity: Activity
  13. {
  14. protected override void OnCreate(Bundle bundle)
  15. {
  16. base.OnCreate(bundle);
  17. // Set our view from the "main" layout resource
  18. SetContentView(Resource.Layout.Main);
  19. // Get our button from the layout resource,
  20. // and attach an event to it
  21. Button button = FindViewById < Button > (Resource.Id.MyButton);
  22. button.Click += delegate
  23. {
  24. Android.Net.ConnectivityManager connectivityManager = (Android.Net.ConnectivityManager) GetSystemService(ConnectivityService);
  25. Android.Net.NetworkInfo activeConnection = connectivityManager.ActiveNetworkInfo;
  26. bool isOnline = (activeConnection != null) && activeConnection.IsConnected;
  27. if (isOnline == false)
  28. {
  29. Toast.MakeText(this, "Network Not Enable", ToastLength.Long).Show();
  30. } else
  31. {
  32. LocationManager mlocManager = (LocationManager) GetSystemService(LocationService);;
  33. bool enabled = mlocManager.IsProviderEnabled(LocationManager.GpsProvider);
  34. if (enabled == false)
  35. {
  36. Toast.MakeText(this, "GPS Not Enable", ToastLength.Long).Show();
  37. }
  38. }
  39. };
  40. }
  41. }
  42. }

Step 4 - Press F5 or Build and Run the Application,Click Button once checking the GPS and Network Status, then show output Notification. Here, I disabled only GPS, so the output will come GPS Status only.



Finally, we have successfully created Xamarin Application for checking Network and GPS Status.
