How to resend SMS verification to Firebase Phone Authentication Android?
According to Firebase documentation ( https://firebase.google.com/docs/auth/android/phone-auth#send-a-verification-code-to-the-users-phone ) exists callback
to handle authentication by phone number.
mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
@Override
public void onVerificationCompleted(PhoneAuthCredential credential) {
Log.d(TAG, "onVerificationCompleted:" + credential);
signInWithPhoneAuthCredential(credential);
}
@Override
public void onVerificationFailed(FirebaseException e) {
Log.w(TAG, "onVerificationFailed", e);
}
@Override
public void onCodeSent(String verificationId,
PhoneAuthProvider.ForceResendingToken token) {
Log.d(TAG, "onCodeSent:" + verificationId);
// Save verification ID and resending token so we can use them later
mVerificationId = verificationId;
mResendToken = token;
}
};
My question is about the method onCodeSent
. This is stated in the doc here ( https://firebase.google.com/docs/reference/android/com/google/firebase/auth/PhoneAuthProvider.ForceResendingToken )
which token
can be used to force resend SMS confirmation code. However, after doing some research on the document, I still don't know how.
I would like to ask how do I use this one token
to resend SMS confirmation?

This method is used to resend SMS confirmations.
private void resendVerificationCode(String phoneNumber,
PhoneAuthProvider.ForceResendingToken token) {
PhoneAuthProvider.getInstance().verifyPhoneNumber(
phoneNumber, // Phone number to verify
60, // Timeout duration
TimeUnit.SECONDS, // Unit of timeout
this, // Activity (for callback binding)
mCallbacks, // OnVerificationStateChangedCallbacks
token); // ForceResendingToken from callbacks
}

You can use the Firebase method to resend the verification code like PERSISTENCE and intercept the SMS code to register automatically, like when the progress dialog is launched, and transparent to the user, which is just
// [START resend_verification]
public void resendVerificationCode(String phoneNumber,
PhoneAuthProvider.ForceResendingToken token) {
PhoneAuthProvider.getInstance().verifyPhoneNumber(
phoneNumber, // Phone number to verify
60, // Timeout duration
TimeUnit.SECONDS, // Unit of timeout
activity, //a reference to an activity if this method is in a custom service
mCallbacks,
token); // resending with token got at previous call 'callbacks' method 'onCodeSent'
// [END start_phone_auth]
}
check sms with broadcast receiver in fragment
private BroadcastReceiver smsBroadcastReceiver;
IntentFilter filter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
public static final String SMS_BUNDLE = "pdus";
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
smsBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Log.e("smsBroadcastReceiver", "onReceive");
Bundle pudsBundle = intent.getExtras();
Object[] pdus = (Object[]) pudsBundle.get(SMS_BUNDLE);
SmsMessage messages = SmsMessage.createFromPdu((byte[]) pdus[0]);
Log.i(TAG, messages.getMessageBody());
firebaseVerificationCode = messages.getMessageBody().trim().split(" ")[0];//only a number code
Toast.makeText(getContext(), firebaseVerificationCode,Toast.LENGTH_SHORT).show();
String token = firebaseAutenticationService.getVerificationCode();//your service
firebaseAutenticationService.verifyPhoneNumberWithCode(token,verificationCode);
}
};
}
