What's wrong with my code?!!

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.factButton);
}

}

it gives an error!

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.factButton);

Hi Adrian,

Let's try and get that fixed for you.

What error does it give, and where? Is it whilst you are writing the code or at run time?

Can you copy the output of LogCat that explains the error as that may help us figure out where the problem is.

Steve.

Hello,

The id of the button that you're trying to find is showFactButton, while you're currently referencing factButton. If you change the id, you should be able to pass the Task.
