Getting Bluetooth Adapter working with Xamarin for Android API 19 or above

I am trying my first android project, but having trouble getting the BluetoothAdapter working. I am using Xamarin in Visual Studio with a nexus 5 emulator running Android 4.4 (API 19).

I tried the following code 

BluetoothAdapter bluetoothAdapter = BluetoothAdapter.DefaultAdapter; 
bluetoothAdapter.Enable();

And got an error message

System.NullReferenceException: Object reference not set to an instance of an > object

I also tried

BluetoothAdapter bluetoothAdapter = (BluetoothAdapter)this.GetSystemService(Context.BluetoothService);
bluetoothAdapter.Enable();

and again got an error

System.InvalidCastException: Specified cast is not valid.

This may be a very basic question, but it seems some of the support is outdated since as of Android 4.3 the bluetooth adapter is created in a new way.

Thanks!

Alex

Bluetooh is not supported by the Android emulator, be it the Android SDK one or the Visual Studio Android emulator. It is so specified in the documentation.

Have a look here: https://developer.android.com/studio/run/emulator.html#about
