SMS Retriever API not working with Firebase PhoneAuth

Question

I developed one android application that has firebase phone number authentication. After enter phone number, firbase sent Verification OTP number via SMS. So I add and allow SMS Read permission in my application

Now as per Google Play Policy, We need to remove SMS Read permission and implement SMS Retriever API.

So I implement SMS Retriever API with SmsRetrieverClient, SMSBroadcastReceiver with necessary dependency.

I register broadcast receiver, submit phone number to firebase. I started client.startSmsRetriever(); and It successfully started with onSuccess() callback.

And also I received SMS from Firebase but SMSBroadcastReceiver not getting any callback regarding CommonStatusCodes.SUCCESS and after 5 minutes I getting callback regarding CommonStatusCodes.TIMEOUT.

So any issue regarding firebase message format or other else?

So please help me, Thanks in advance.

Answer 1

Almost an answer : It can't work because the "format" of the SMS content for SMS Retriever to work is "#".... and SHA256 from the app but Firebase SMS format is different so the SMS Retriever is not "recognising" the SMS as a valid one.
