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

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

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

<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

using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
using Android.Locations;
namespace CheckNetwork
{
    [Activity(Label = "CheckNetwork", MainLauncher = true, Icon = "@drawable/icon")]
    public class MainActivity: Activity
    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);
            // Get our button from the layout resource,
            // and attach an event to it
            Button button = FindViewById < Button > (Resource.Id.MyButton);
            button.Click += delegate
            {
                Android.Net.ConnectivityManager connectivityManager = (Android.Net.ConnectivityManager) GetSystemService(ConnectivityService);
                Android.Net.NetworkInfo activeConnection = connectivityManager.ActiveNetworkInfo;
                bool isOnline = (activeConnection != null) && activeConnection.IsConnected;
                if (isOnline == false)
                {
                    Toast.MakeText(this, "Network Not Enable", ToastLength.Long).Show();
                } else
                {
                    LocationManager mlocManager = (LocationManager) GetSystemService(LocationService);;
                    bool enabled = mlocManager.IsProviderEnabled(LocationManager.GpsProvider);
                    if (enabled == false)
                    {
                        Toast.MakeText(this, "GPS Not Enable", ToastLength.Long).Show();
                    }
                }
            };
        }
    }
}

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.
