Initialize the showFactButton variable using the findViewById() method like the TextView above it. The ID for the button

what does it mean

FunFactsActivity.java 
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class FunFactsActivity extends Activity {

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

        // Declare our View variables and assign them the Views from the layout file
        TextView factLabel = (TextView) findViewById(R.id.factTextView);
        Button showFactButton;
    }
}

Hello,

What you are wanting to do is set the Button variable called showFactButton. It has already been started for you with

Button showFactButton;

What you want to do is finish that line of code following the example on the previous line of 

TextView factLabel = (TextView) findViewById(R.id.factTextView);

If you need more help, feel free to ask and I will try to assist.
