否。我们不需要管理短信检索方案。

如果设备包含相同的SIM卡，则由onVerificationCompleted(PhoneAuthCredential phoneAuthCredential)方法中的PhoneAuthProvider.OnVerificationStateChangedCallbacks自动管理。

片段：

private PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {

        @Override
        public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
            Toast.makeText(FCMsmsTest.this, "onVerificationCompleted " + phoneAuthCredential.toString(), Toast.LENGTH_SHORT).show();
            signInWithPhoneAuthCredential(phoneAuthCredential);
        }

        @Override
        public void onVerificationFailed(FirebaseException e) {
            Toast.makeText(FCMsmsTest.this, "onVerificationFailed " + e.toString(), Toast.LENGTH_SHORT).show();

            if (e instanceof FirebaseAuthInvalidCredentialsException) {
                Toast.makeText(FCMsmsTest.this, "Invalid Request " + e.toString(), Toast.LENGTH_SHORT).show();
            } else if (e instanceof FirebaseTooManyRequestsException) {
                Toast.makeText(FCMsmsTest.this, "The SMS quota for the project has been exceeded " + e.toString(), Toast.LENGTH_SHORT).show();
            }
        }

        @Override
        public void onCodeSent(String verificationId,
                               PhoneAuthProvider.ForceResendingToken token) {
            Toast.makeText(FCMsmsTest.this, "onCodeSent " + verificationId, Toast.LENGTH_SHORT).show();
            editText.setText("");

            mVerificationId = verificationId;
            PhoneAuthProvider.ForceResendingToken mResendToken = token;

            showDialog();
        }
    };
