I get an eror like this.. location provider requires ACCESS_FINE_LOCATION permission
- Anbu Mani6y ago
  Please provide the Permissions in AndroidManifest.xml, Else above Android 6.0 Version you need to get runtime permission.. Please check here https://docs.microsoft.com/en-us/xamarin/android/app-fundamentals/permissions?tabs=windows

  Anbu Mani I downloaded the source code you provided and it gives the latitude and longitude but the problem is it is not giving my location but some other location. Please help me out if you have a solution for it.

  It is not an error it gives a location with latitude and longitude but it is not my location it is some location of google plex in sanfransisco. I tired to debug a couple of times but it still takes me to that location instead of my location

  Thanks

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.

Click to open Code Window.

Step 6

Next go to MainActivity.cs Add one Namespace and then go Mainactivity Class to add Interface for ILocationListener after add Interface that time will show some Events missing error then click to add Implement interface. After that Automatically create some methods.

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 - Then go to MainActivity.cs below of OnCreate() to declare InitializeLocationManager().This Method to call 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().This section to get Current Location Latitude and Longitude Information. That information will assign 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.
