Question

我已经按照firebase docs的指导方针来实现登录我的应用程序，但是注册时出现问题，该应用程序崩溃了，并且目录显示了以下错误：

Process: app, PID: 12830
    java.lang.IllegalArgumentException: Cannot create PhoneAuthCredential without either verificationProof, sessionInfo, ortemprary proof.

我尝试查看其他代码示例，但它们与我的代码相似，但我的应用程序因相同的错误而崩溃。

这是我使用firebase文档的指南编写的代码：

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private FirebaseAuth mAuth;
    private String mVerificationId;
    private PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks;
    Button login,verify,signout;
    EditText number;
    EditText code;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mAuth = FirebaseAuth.getInstance();
        login = findViewById(R.id.btnlogin);
        verify = findViewById(R.id.btnverify);
        signout = findViewById(R.id.btnsignout);
        number = findViewById(R.id.editnumber);
        code = findViewById(R.id.editcode);
        login.setOnClickListener(this);
        verify.setOnClickListener(this);
        signout.setOnClickListener(this);

        mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
            @Override
            public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
                signInWithPhoneAuthCredential(phoneAuthCredential);
            }

            @Override
            public void onVerificationFailed(FirebaseException e) {
                Toast.makeText(MainActivity.this, "Error" + e.toString(), Toast.LENGTH_SHORT).show();
                if (e instanceof FirebaseAuthInvalidCredentialsException) {
                    Toast.makeText(MainActivity.this, "Invalid Request " + e.toString(), Toast.LENGTH_SHORT).show();
                } else if (e instanceof FirebaseTooManyRequestsException) {
                    Toast.makeText(MainActivity.this, "The SMS quota for the project has been exceeded " + e.toString(), Toast.LENGTH_SHORT).show();
                }
            }

            @Override
            public void onCodeSent(String vId, PhoneAuthProvider.ForceResendingToken forceResendingToken) {
                Toast.makeText(MainActivity.this, "Code Sent" + vId, Toast.LENGTH_SHORT).show();
                number.setText("");
              mVerificationId = vId;
            }
        };
    }

    private void signInWithPhoneAuthCredential(PhoneAuthCredential phoneAuthCredential) {
        mAuth.signInWithCredential(phoneAuthCredential).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
                if (task.isComplete()){
                    FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
                    String uid = null;
                    if (user != null) {
                        uid = user.getUid();
                    }
                    Toast.makeText(MainActivity.this, "Signed In", Toast.LENGTH_SHORT).show();
                    Toast.makeText(MainActivity.this, uid, Toast.LENGTH_SHORT).show();
                } else {
                    if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
                        Toast.makeText(MainActivity.this, "Invalid Code", Toast.LENGTH_SHORT).show();
                    }
                }
            }
        });
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btnlogin: {
                String phonenumber = number.getText().toString();
                startPhoneNumberVerification(phonenumber);
            }
            case R.id.btnverify: {
                String vCode = code.getText().toString();
                verifyPhoneNumberWithCode(mVerificationId, vCode);
            }
            case R.id.btnsignout: {
                mAuth.signOut();
            }
        }
    }

    private void startPhoneNumberVerification(String phoneNumber) {
        PhoneAuthProvider.getInstance().verifyPhoneNumber(phoneNumber, 60, TimeUnit.SECONDS, this, mCallbacks);
    }

    private void verifyPhoneNumberWithCode(String verificationId, String code) {
        PhoneAuthCredential credential = PhoneAuthProvider.getCredential(verificationId, code);
        signInWithPhoneAuthCredential(credential);
    }

}

上面的代码将otp发送到给定的数字，但是它崩溃了，并且cat-log显示了上面提到的错误。

请尝试帮助我找出我的代码中的错误，而不是参考其他代码。

你得到的号码没有国家代码，比如 +91 使用国家代码或使用

String withCountryCode = "+91"+code PhoneAuthCredential 凭证 = PhoneAuthProvider.getCredential(verificationId, withCountryCode); signInWithPhoneAuthCredential(credential);

没有verifyProof不能创建PhoneAuthCredential吗？
