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

what is it that is needed here, i cannt seem to get it right, what is wrong with my code

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 = (Button)  findViewById(R.id.shawFactButton);
    }
}

Hi Farai. Whenever your challenge fails, you get a message at the top. Here it says: "Bummer: There is a compiler error. Please click on preview to view your syntax errors!"

If you click on Preview, you will see the following:

./FunFactsActivity.java:16: error: cannot find symbol
        Button showFactButton = (Button)  findViewById(R.id.shawFactButton);
                                                                                                 ^
  symbol:   variable shawFactButton
  location: class id
1 error

So it tells you the problem is that it cannot find symbol, then further down it indicates what symbol it cannot find: symbol: variable shawFactButton

Looking at it carefully, you will notice that you have a small typo: it should be showFactButton, not shawFactButton.

Correct this and you'll be good to go. Hope that helps :)
