问题

这是关于使用 Firebase 进行电话号码验证的应用程序。但我一直收到“验证失败”的消息。以下是 OTP 验证的代码：

private void sendVerificationCode(){
    String phoneN =phone.getText().toString();
    
    PhoneAuthProvider.getInstance().verifyPhoneNumber(
            phoneN,                           
            60,                  
            TimeUnit.SECONDS,   
            Registration.this,               
            mCallbacks);        
}

PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks= new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
    @Override
    public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
        Toast.makeText(Registration.this,"验证完成",Toast.LENGTH_SHORT).show();
        signInWithPhoneAuthCredential(phoneAuthCredential);
    }

    @Override
    public void onVerificationFailed(FirebaseException e) {
        Toast.makeText(Registration.this,"验证失败",Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken forceResendingToken) {
        codeSent=s;
    }
};
private void VerifyCode(){
    String code= otp.getText().toString();
    PhoneAuthCredential credential = PhoneAuthProvider.getCredential(codeSent, code);
    signInWithPhoneAuthCredential(credential);
}
private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) {
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        Toast.makeText(getApplicationContext(),"欢迎，现在您可以登录", Toast.LENGTH_LONG).show();
                        Intent intent = new Intent(Registration.this,Login_Reg.class);
                        startActivity(intent);

                    } else {
                        if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
                            // 输入的验证码无效
                            Toast.makeText(getApplicationContext(),"验证码不正确",Toast.LENGTH_LONG).show();
                        }

                    }
                }
            });
}
}

我一直收到“验证失败”的消息。以下是用户界面(UI)。

如何解决这个问题？

    private void sendVerificationCode(){
String phoneN =phone.getText().toString();
PhoneAuthProvider.getInstance().verifyPhoneNumber(
phoneN,                           60,                 
TimeUnit.SECONDS,   
Registration.this,               
mCallbacks);        
}
PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks= new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
@Override
public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
Toast.makeText(Registration.this,"verification completed",Toast.LENGTH_SHORT).show();
signInWithPhoneAuthCredential(phoneAuthCredential);
}
@Override
public void onVerificationFailed(FirebaseException e) {
Toast.makeText(Registration.this,"verification failed",Toast.LENGTH_SHORT).show();
}
@Override
public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken forceResendingToken) {
//super.onCodeSent(s, forceResendingToken);
codeSent=s;
}
};
private void VerifyCode(){
String code= otp.getText().toString();
PhoneAuthCredential credential = PhoneAuthProvider.getCredential(codeSent, code);
signInWithPhoneAuthCredential(credential);
}
private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) {
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Toast.makeText(getApplicationContext(),"Welcome, You can login now", Toast.LENGTH_LONG).show();
Intent intent = new Intent(Registration.this,Login_Reg.class);
startActivity(intent);
} else {
if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
// The verification code entered was invalid
Toast.makeText(getApplicationContext(),"Incorrect Verification Code",Toast.LENGTH_LONG).show();
}
}
}
});
}
}
