Xamarin Android: Create Android Application To Check Network And GPS Status

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" />  
  2.   
  3. <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />  
  4.   
  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.
