The app has stopped working because of an animation issue

Hi I am new to android development and I am creating a basic app with buttons and animation however, one button works with animation but the other button stops the app completely and there is no error. Btn 1 (Button 1) works but Btn 2 (Button 2) stops the app. The java code is below. Any help is appreciated, thanks in advance.

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

           final Animation animAlpha = AnimationUtils.loadAnimation(this, R.anim.anim_alpha);

    Button btn1 = (Button) findViewById(R.id.categories);

    btn1.setOnClickListener(new Button.OnClickListener()
    {
        @Override
        public void onClick(View arg0) {
            arg0.startAnimation(animAlpha);
            Intent intent = new Intent(getApplicationContext(), Categories.class); 
            Vibrator  vibrator = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
            vibrator.vibrate(25);
            Button btn1= (Button) findViewById(R.id.categories);
            btn1.setBackgroundResource(R.drawable.button_shape2);
            startActivity(intent);

     Button btn2 = (Button) findViewById(R.id.feedback);

       btn2.setOnClickListener(new Button.OnClickListener()
    {
            @Override
            public void onClick(View arg0) {
                arg0.startAnimation(animAlpha);
                Intent intent = new Intent(getApplicationContext(), Feedback.class); 
                Vibrator  vibrator = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
                vibrator.vibrate(25);
                Button btn2= (Button) findViewById(R.id.feedback);
                btn2.setBackgroundResource(R.drawable.button_shape2);
                startActivity(intent);}
            });}{;

           };
       });}};

Caused by: java.lang.NoSuchMethodException: Feedback

Does your xml mention that onClick, the button should call the method feedback ? Because that's the issue, this method does not exist, making the app crash.

Implement it to solve this issue.
