我尝试使用FCM进行Otp验证，并且未生成OTP

如何解决我尝试使用FCM进行Otp验证，并且未生成OTP

我有一个名为VerifyphoneActivity的活动，正在将edittext值传递给另一个名为FirstActivity的活动，在该活动中，我使用此值来验证我的号码并生成OTP。它显示了吐司“提供的字符串似乎不是电话号码这是我的代码：

VerifyPhoneActivity.java

公共类VerifyPhoneActivity扩展了AppCompatActivity {

   EditText phoneNoEnteredByUser;

   Button generateOtp;

   String phoneNumber;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_verify_phone);
    phoneNoEnteredByUser = (EditText) findViewById(R.id.phoneNumberEdittext);
    generateOtp = (Button) findViewById(R.id.generateOtp);
    phoneNumber = phoneNoEnteredByUser.getText().toString();
    generateOtp.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent i = new Intent(getApplicationContext(),FirstActivity.class);
            i.putExtra("phoneNumber",phoneNumber);
            startActivity(i);
        }
    });
}

}

FirstActivity.java

公共类FirstActivity扩展了AppCompatActivity { String verificationCodeBySystem; 按钮verifyPhone； EditText phoneNumberUser; ProgressBar progressBar; 字符串电话号码； 字符串e164Number; FirebaseAuth firebaseAuth;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_first);
    verifyPhone = (Button) findViewById(R.id.verifyBtn);
    phoneNumberUser = (EditText) findViewById(R.id.verifyEditText);
    progressBar = (ProgressBar) findViewById(R.id.progressBar);
    progressBar.setVisibility(View.GONE);
    phoneNo = getIntent().getStringExtra("phoneNumber");
    
   `Log.d("FirstActivity","phoneNo:- " + phoneNo);

    sendVerificationCodeToUser(phoneNo,"IND");

    verifyPhone.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String code = phoneNumberUser.getText().toString();
            if (code.isEmpty() | code.length() < 6) {
                phoneNumberUser.setError("Wrong OTP...");
                phoneNumberUser.requestFocus();
                return;
            }
            progressBar.setVisibility(View.VISIBLE);
            verifyCode(code);
        }
    });
