Google Places Autocomplete is not working Sometimes in Xamarin Android Project - google-maps

Question

I am implementing Google Places Autocomplete in my Xamarin Android project. (This is not a Xamarin Forms Project).
When I search first time, the autocomplete works properly but consequent searches do not work properly.
Even if the autocomplete works, if I select an item, it will not call OnActivityResult function and get back the above screen again.
Even these posts did not solve my problem
Google Places Autocomplete Can't load search results
Android onActivityResult not called / triggered
I have not set a billing account but I dont think that is the problem because it works sometimes. How can I solve this issue?
(Please note this is not a duplicate question since I could not find any questions like this)
This is the code I am using to open Google Places Autocomplete view
private void BtnLocationOnClick(object sender, EventArgs e)
{
List<Place.Field> fields = new List<Place.Field>();
fields.Add(Place.Field.Id);
fields.Add(Place.Field.Name);
fields.Add(Place.Field.LatLng);
fields.Add(Place.Field.Address);
Intent intent = new Autocomplete.IntentBuilder(AutocompleteActivityMode.Overlay, fields)
.SetCountry("US")
.Build(this);
StartActivityForResult(intent, 1);
}
Once the item is selected OnActivityResult function need to be called
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
base.OnActivityResult(requestCode, resultCode, data);
if (requestCode == 1)
{
if (resultCode == Android.App.Result.Ok)
{
Place place = Autocomplete.GetPlaceFromIntent(data);
txtLocation.Text = place.Name;
googleMap.AnimateCamera(CameraUpdateFactory.NewLatLngZoom(place.LatLng, 15));
}
}
}

Enabling billing on your project is mandatory for the Places API (or any other Maps API) to work. Otherwise you are limited to 1 request per day.
Follow Google's get started guide to create a billing account and link it to your project.
Also make sure that the Places API is enabled on your project too.
Hope this helps!
