3,781 PointsHey Riya! Ez mistake to make! Just needs to be in the onCreate method with the correct id.
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
protected Button growthButton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
growthButton = (Button) findViewById(R.id.button1);
}
}

806 PointsThanks so much Tony. I had tried putting it inside the onCreate method, didnt work though. But after seeing your code I realized that I was putting R.Id.button1, "I" was in caps. changed it to smaller case it worked. Thanks again. Aprreciate your help.
