android studio parseInt/getInt/Valueof hatası alıyorum ...

Herkese merhaba ben yeni android öğreniyorum ama yaptığım bir uygulamada nesneden aldığım veriyi integer e çeviremiyorum

önce stringe çevirdim sonra integere ama olmadı direkt çevirdim gene olmadı

android studio da kod hata vermiyor ama telefonda da açılmıyor her zaman uygulama durduruldu hatası alıyorum

bu java nın kodu(daha tamamlanmadı):

package com.yf.myapplication;

import androidx.appcompat.app.AppCompatActivity;

import android.annotation.SuppressLint;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import java.util.Random;

public class MainActivity extends AppCompatActivity {
	Random r1=new Random();
	Random r2=new Random();
	Random operation_r=new Random();
	TextView resault,number_one,operation,number_two;
	EditText resault_input;
	Button change;
	int s1,s2,sonuc,operation_i,input;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		number_one=(TextView)findViewById(R.id.number_one);
		operation=(TextView)findViewById(R.id.operation);
		number_two=(TextView)findViewById(R.id.number_two);
		resault=(TextView)findViewById(R.id.resault);
		resault_input=(EditText) findViewById(R.id.resault_input);
		change=(Button)findViewById(R.id.change);
		tick();
		p_random();
	}
	@SuppressLint("ResourceAsColor")
	public void p_random(){
		s1=r1.nextInt(999)+1;
		s2=r2.nextInt(999)+1;
		operation_i=operation_r.nextInt(4)+1;
		number_one.setText(""+s1);
		number_two.setText(""+s2);
		input=Integer.parseInt(resault_input.getText().toString());
		if ( operation_i==1 ) {
			sonuc=s1+s2;
			operation.setText(" + ");
			if ( input==sonuc ){resault.setTextColor(R.color.green);resault.setText("TRUE");
			}
			else {resault.setText("FALSE\n"+sonuc); resault.setTextColor(R.color.red);}
		}
		else if ( operation_i==2 ) {
			sonuc=s1-s2;
			operation.setText(" - ");
			resault.setText(""+sonuc);
		}
		else if ( operation_i==2 ) {
			sonuc=s1*s2;
			operation.setText(" x ");
			resault.setText(""+sonuc);
		}
		else if ( operation_i==4 ){
			sonuc=s1/s2;
			operation.setText(" / ");
			resault.setText(""+sonuc);
		}
	}
	public void tick(){
		change.setOnClickListener(new View.OnClickListener() {
			@Override
			public void onClick(View v) {
				p_random();
			}
		});
	}
}

bu da xml kodu:
