Help with calculation exercise in hours in android studio

In this exercise, I have to start with one hour of entry (example: 20:30), after that, I have to add the minutes to get the time of departure.

But I have two details which I do not know what they are, the first one indicates an error of "Wrong 2nd argument type. Found: 'long', required: 'int" and the second "Can not resolve method' makeText" What should they do?

    package com.example.yasna.myapp_ejerciciohoras;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.time.format.DateTimeFormatter;
import java.util.Calendar;
import java.util.Date;
import java.util.concurrent.TimeUnit;

public class MainActivity extends AppCompatActivity {

    private EditText edtH1;
    private EditText edtM1;
    private EditText edtM2;
    private EditText edtH2;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        edtH1=(EditText) findViewById(R.id.edtHora);
        edtM1=(EditText) findViewById(R.id.edtMin1);
        edtM2=(EditText) findViewById(R.id.edtMin2);
        edtH2=(EditText) findViewById(R.id.edtHora2);

    }

    public void calcularHora(View view){




        String Hora =edtH1.getText().toString() ; // sin espacio
        SimpleDateFormat formato = new SimpleDateFormat("hh:mm");
        Date horas = null;
        try {
            horas = formato.parse(Hora);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        String horasformato = formato.format(horas);

        /************/
        Calendar HoraFinal=Calendar.getInstance();
        HoraFinal.setTime(horas);



        /***********/



        int min= Integer.parseInt(edtM1.getText().toString())+Integer.parseInt(edtM2.getText().toString());


        String formato2 = "%02d:%02d" ;
        long horasReales = TimeUnit.MINUTES.toHours(min);
        long minutosReales = TimeUnit.MINUTES.toMinutes(min) - TimeUnit.HOURS.toMinutes(TimeUnit.MINUTES.toHours(min));

        HoraFinal.add(Calendar.HOUR, horasReales);
        HoraFinal.add(Calendar.MINUTE, minutosReales);


        Toast.makeText(this, HoraFinal.getTime(),Toast.LENGTH_SHORT).show();
        Toast.makeText(this, String.format(formato2, horasReales, minutosReales),Toast.LENGTH_SHORT).show();
//aqui







       Toast.makeText(this,horasformato,Toast.LENGTH_SHORT).show();
