Android Build an Interactive Story App User Input Finding Views by IDs

can someone look at my code and tell me where i am going wrong with this challenge?

i don't see where i am going wrong ? Initialize the member variable mExterminateButton using the findViewById() method. The ID for the button is button1. Don't forget to cast the generic View returned by the method!

import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    protected Button exterminateButton;

    public void onCreate(Bundle savedInstanceState) {

        // Declare our view variables
      mExterminateButton = (Button) findViewById(R.id.button1);

Take a closer look at your variables.

ok so i got it. can you explain to me why the (m) wasn't necessary ?

Because the variable was never declared with the prefix 'm'. You'll run into different code styles in your career of programming. It's good to adapt to them, assuming every variable has 'm' prefixed should not happen.
