MainActivity

[Activity(Label = "Hello World Band Android", MainLauncher = true, Icon = "@drawable/icon")]
public class MainActivity : Activity {
    protected override void OnCreate(Bundle bundle) {
        base.OnCreate(bundle);
        SetContentView(Resource.Layout.Main);
        Button button = FindViewById<button>(Resource.Id.MyButton);

        SetupBand();

        button.Click += delegate
        {
            if (myBand != null && myBand.BandClient.IsConnected)
                button.Text = string.Format("Connected to {0}!", myBand.Name);
            else
                Toast.MakeText(this, "Band not yet connected or not found!", ToastLength.Long);
        };
    }

    private async void SetupBand() {
        // get instance
        myBand = Band.Instance;
        await myBand.PairBand();
    }
