Question

第一次登录并注销后，下次登录时，我没有获得OTP。我该如何解决这个问题？如果我是第一次输入电话号码，该代码可以正常工作。第二次起，我没有收到OTP号码。为了获得OTP号码，我需要每次重新启动手机。如果我关闭然后重新打开该应用程序，那么它也帮不了我。

验证电话活动

public class VerifyPhoneActivity extends AppCompatActivity {

    private String verificationId;
    private FirebaseAuth mAuth;
    private ProgressBar progressBar;
    private EditText editText;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_verify_phone);

        mAuth = FirebaseAuth.getInstance();

        editText = findViewById(R.id.editTextCode);

        progressBar =findViewById(R.id.progressbar);

        String phonenumber = getIntent().getStringExtra("phonenumber");
        setVerificationCode(phonenumber);

        findViewById(R.id.buttonSignIn).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                String code = editText.getText().toString().trim();
                if(code.isEmpty() || code.length()< 6){
                    editText.setError("Enter code");
                    editText.requestFocus();
                    return;
                }
                verifyCode(code);

            }
        });

    }

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

    private void SignInWithCredential(PhoneAuthCredential credential) {
        mAuth.signInWithCredential(credential)
                .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if(task.isSuccessful()){

                            Intent intent = new Intent(VerifyPhoneActivity.this, ProfileActivity.class);
                            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

                            startActivity(intent);
                        }else {
                            Toast.makeText(VerifyPhoneActivity.this, task.getException().getMessage(),Toast.LENGTH_LONG).show();
                        }

                    }
                });
    }

    private void setVerificationCode(String number){
        progressBar.setVisibility(View.VISIBLE);
        PhoneAuthProvider.getInstance().verifyPhoneNumber(
                number,
                60,
                TimeUnit.SECONDS,
                TaskExecutors.MAIN_THREAD,
                mCallBack
        );
    }

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

        @Override
        public void onCodeSent(String s, PhoneAuthProvider.ForceResendingToken forceResendingToken) {
            super.onCodeSent(s, forceResendingToken);
            verificationId = s;
        }

        @Override
        public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
            String code =phoneAuthCredential.getSmsCode();
            if(code != null){
                editText.setText(code);
                SignInWithCredential(phoneAuthCredential);
            }

        }

        @Override
        public void onVerificationFailed(FirebaseException e) {
            Toast.makeText(VerifyPhoneActivity.this, e.getMessage(), Toast.LENGTH_LONG).show();

        }
    };

如果移动设备在firebase上注册，则它不会一直发送OTP（也许是几次），您应该阅读文档。

注册手机后，您将获得成功，然后可以进行验证。

第一次注销后如何第二次获得OTP？
