我已将firebase电话身份验证添加到我的 android 项目中。首先一切顺利。一段时间后，短信代码onVerificationCompleted()为空。谢谢！！

PhoneAuthProvider.getInstance().verifyPhoneNumber(mobileNumber, 60, TimeUnit.SECONDS, FirebasePhoneAuthActivity.this, new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
    @Override
    public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
        smsCode = phoneAuthCredential.getSmsCode();
        Log.i(TAG, "onVerificationCompleted: CODE " + smsCode);
        Log.i(TAG, "onVerificationCompleted: PROVIDER " + phoneAuthCredential.getProvider());
    }

    @Override
    public void onVerificationFailed(FirebaseException e) {
        e.printStackTrace();
    }

    @Override
    public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken forceResendingToken) {
        Log.i(TAG, "onCodeSent: CODE " + s);

    }

    @Override
    public void onCodeAutoRetrievalTimeOut(String s) {
        super.onCodeAutoRetrievalTimeOut(s);
        Log.i(TAG, "onCodeAutoRetrievalTimeOut: " + s);
    }
});
