Let’s start,

Step 1 : Open Visual Studio->New Project->Templates->Visual C#->Android, then select Blank App (Android),Give Project Name and Project Location.

Step 2 : Next go to Solution Explorer-> Project Name->AndroidManifest.xml open xml code and give the Permission for Location, Network, Coarse Location services.

XML Code :-

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

Step 3 : Next open Solution Explorer-> Project Name->Resources->layout->Main.axml click to open Design View.

Step 4 : Then Select Toolbar Drag and Drop Five Textview box.

XML Code :-

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="vertical" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 
<TextView 
android:text="CURRENT LOCATION" 
android:textAppearance="?android:attr/textAppearanceLarge" 
android:layout_width="214.5dp" 
android:layout_height="wrap_content" 
android:id="@+id/textView1" 
android:layout_gravity="center_horizontal" /> 
 <TextView 
android:text="Latitude" 
android:textAppearance="?android:attr/textAppearanceLarge" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:id="@+id/textView2" /> 
<TextView 
android:textAppearance="?android:attr/textAppearanceMedium" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:id="@+id/txtlatitude" /> 
<TextView 
android:text="Longitude" 
android:textAppearance="?android:attr/textAppearanceLarge" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:id="@+id/textView4" /> 
<TextView 
android:textAppearance="?android:attr/textAppearanceMedium" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:id="@+id/txtlong" /> 
</LinearLayout>

Step 5 : Next open Solution Explorer, Project Name, MainActivity.cs.

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; 
 using System.Collections.Generic; 
 using Android.Util; 
 using System.Linq; 
 namespace CurrentLocation 
 { 
 [Activity(Label = "CurrentLocation", MainLauncher = true, Icon = "@drawable/icon")] 
 public class MainActivity: Activity, ILocationListener 
 { 
 TextView txtlatitu; 
 TextView txtlong; 
 Location currentLocation; 
 LocationManager locationManager; 
 string locationProvider; 
 public string TAG 
 { 
 get; 
 private set; 
 } 
 protected override void OnCreate(Bundle bundle) 
 { 
 base.OnCreate(bundle); 
 // Set our view from the "main" layout resource 
 SetContentView(Resource.Layout.Main); 
 txtlatitu = FindViewById < TextView > (Resource.Id.txtlatitude); 
 txtlong = FindViewById < TextView > (Resource.Id.txtlong); 
 InitializeLocationManager(); 
 } 
 } 
 }

Step 7 :  Next go to MainActivity.cs below of OnCreate() here to declare InitializeLocationManager().In This Method to called in onCreate().

C# Code :-

 private void InitializeLocationManager() 
 { 
 locationManager = (LocationManager) GetSystemService(LocationService); 
 Criteria criteriaForLocationService = new Criteria 
 { 
 Accuracy = Accuracy.Fine 
 }; 
 IList < string > acceptableLocationProviders = locationManager.GetProviders(criteriaForLocationService, true); 
 if (acceptableLocationProviders.Any()) 
 { 
 locationProvider = acceptableLocationProviders.First(); 
 } else 
 { 
 locationProvider = string.Empty; 
 } 
 Log.Debug(TAG, "Using " + locationProvider + "."); 
 }

Step 8 : Next to create OnResume() and OnPause Methods.

C# Code :-

 protected override void OnResume() 
 { 
 base.OnResume(); 
 locationManager.RequestLocationUpdates(locationProvider, 0, 0, this); 
 } 
 protected override void OnPause() 
 { 
 base.OnPause(); 
 locationManager.RemoveUpdates(this); 
 }

Step 9 : Finally go to OnLocationChanged().In This section to get Current Location Latitude and Longitude Information. This information will be assigned in Textview.

C# Code :-

public void OnLocationChanged(Location location)
{
currentLocation = location;
if (currentLocation == null)
{
//Error Message
} else
{
txtlatitu.Text = currentLocation.Latitude.ToString();
txtlong.Text = currentLocation.Longitude.ToString();
}
}

Step 10 :  Press F5 or Build and run the Application.

Finally, we have successfully created Xamarin Android GPS Current Location Application.
