mealLayout.SetBackgroundColor(Color.GREEN); : what is wrong with this line of code? Gives me a compiler error.

Bummer?

MealActivity.java
import android.os.Bundle;
import android.widget.TextView;

public class MealActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_meal);

        TextView foodLabel = (TextView) findViewById(R.id.foodTextView);
        TextView drinkLabel = (TextView) findViewById(R.id.drinkTextView);
        RelativeLayout mealLayout = (RelativeLayout) findViewById(R.id.mealLayout);
        mealLayout.SetBackgroundColor(Color.GREEN);
    }
}

The letter 's' in "SetBackgroundColor" should be lowercase.
