[Firebase database screenshot][1]
[![firebase database ][1]][1]
I'm a beginner at android and firebase and am developing a driving school app. I am to successfully add customer details to a firebase database ('name', 'phone', 'fromdate' and 'todate'). I want to send an sms alert to the customer e.g. ("your licence is expiry soon.") using 'phone' and 'date' from the firebase database. The sms should be sent on expiry date (I mean 'todate' in the firebase database). Here I've attached my firebase database screenshot. Please give me an example of how to do this.
Update customer details
public class Updatecustomer extends AppCompatActivity {
private EditText edtname, edtpho;
private Button btnsubmit;
private EditText datepickerto, datepickerfr;
private Calendar mcurrentDate, mlateDate;
int day, month, year;

private DatabaseReference listref;
private DatabaseReference noderef;

mcurrentDate = Calendar.getInstance();

month = mcurrentDate.get(Calendar.MONTH);
year = mcurrentDate.get(Calendar.YEAR);
day = day+1;
datepickerto.setText(day+"-"+month+"-"+year);
datepickerto.setOnClickListener(new View.OnClickListener() {
@Override

DatePickerDialog(Updateproduction.this, new

monthOfYear, int dayOfMonth) {
