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,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 the Permission for Network and Location services.
<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.
