Code Verifier

Copy verification code from SMS automatically.

Activity class should implement SMSReceiver.SMSListener.

For example,

public class MainActivity extends AppCompatActivity implements SMSReceiver.SMSListener {
  ................ .................  
}
 

Create Broadcast Receiver like this

 SMSReceiver smsReceiver = new SMSReceiver();
  

OnResume method of activty class add this line

  smsReceiver.registerReceiver(this, smsReceiver, "TM-bytwoo", "9480523270","specify 3rd phone number here");

smsReceiver.setSMSListener(this);
 

Using onSMSReceived(....) method, parse the verification code

for example, if you want to parse verification code from this sms, "201232 is your One Time Password" then we should write this code

@Override
  public void onSMSReceived(String phone_no, String message) {
  // 1st parameter ---> message // second parameter ---> position of first character of the OTP // second parameter ---> position of character after last character (includes white space) of OTP

Strng OTP = smsReceiver.extractCode(message, 0, -999);

 
}

  

Unregister BroadCast Receiver in your activities OnPause() method.

  @Override
  protected void onPause() {

super.onPause();

if (smsReceiver!=null) {

 smsReceiver.unregisterReceiver(this, smsReceiver);

}

}
