Calendar on android using Date Picket

I am trying to add a calendar to my application, my code is as follows:

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

    btn_fecha = (Button)findViewById(R.id.btn_fecha);
    btn_hora = (Button)findViewById(R.id.btn_hora);
    btn_next_fecha = (Button)findViewById(R.id.btn_next_fecha);
    eFecha = (EditText)findViewById(R.id.eFecha);
    eHora = (EditText)findViewById(R.id.eHora);
    btn_fecha.setOnClickListener(this);
    btn_hora.setOnClickListener(this);
}

@Override
protected void onResume() {
    super.onResume();
    btn_next_fecha = (Button)findViewById(R.id.btn_next_fecha);

    btn_next_fecha.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent btn_next_fecha = new Intent(SelectDayActivity.this, DatosAutoActivity.class);
            startActivity(btn_next_fecha);
        }
    });
}

@RequiresApi(api = Build.VERSION_CODES.N)
@Override
public void onClick(View v) {
    if (v==btn_fecha){
        final Calendar c = Calendar.getInstance();
        dia = c.get(Calendar.DAY_OF_MONTH);
        mes = c.get(Calendar.MONTH);
        ano = c.get(Calendar.YEAR);


        DatePickerDialog datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {

            @Override
            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                eFecha.setText(dayOfMonth+"/"+(month+1)+"/"+year);
            }
        }
        ,dia, mes, ano);
        datePickerDialog.show();


    }

My code works, however, when the calendar appears it shows the year 1900 and I would like it to appear today's date (the current date that the cell phone has)

Could you support me to do that? Thanks
