我无法获得 Firebase 电话验证短信代码吗？

Question

我正在使用 Firebase PhoneAuth 来授权用户。它的作用是自动触发成功回调并且不返回代码，即使它向我发送了 SMS。我需要更新我的 UI 中的 SMS 代码，因为我在任何地方都没有收到它，或者我认为我在这里遗漏了一些东西。

这是我的代码：

public class OTPActivity extends Activity {

  private TextView tvTimer;
  private int timeCount = 30;
  private ImageButton ibBack;
  private FirebaseAuth mAuth;
  private String mVerificationId;
  private PhoneAuthProvider.ForceResendingToken mResendToken;

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

    Constants.removeStatusBar(this);

    ibBack = findViewById(R.id.ibBack);
    tvTimer = findViewById(R.id.tvTimer);

    String phoneNumber = "+91" + getIntent().getStringExtra("phone");

    Handler h = new Handler();
    h.postDelayed(new Runnable() {
      @Override
      public void run() {
        if (timeCount > 0) {
          tvTimer.setText("You can resend OTP after 00:" + timeCount + "s");
          timeCount--;
          h.postDelayed(this, 1000);
        }
      }
    }, 0);

    ibBack.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        onBackPressed();
      }
    });

    mAuth = FirebaseAuth.getInstance();

    PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks = new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {

      @Override
      public void onVerificationCompleted(PhoneAuthCredential credential) {
        // This callback will be invoked in two situations:
        // 1 - Instant verification. In some cases the phone number can be instantly
        //     verified without needing to send or enter a verification code.
        // 2 - Auto-retrieval. On some devices Google Play services can automatically
        //     detect the incoming verification SMS and perform verification without
        //     user action.
        Log.d(Constants.TAG, "onVerificationCompleted:" + credential);

        signInWithPhoneAuthCredential(credential);
      }


      @Override
      public void onVerificationFailed(FirebaseException e) {
        // This callback is invoked in an invalid request for verification is made,
        // for instance if the the phone number format is not valid.
        Log.w(Constants.TAG, "onVerificationFailed", e);

        if (e instanceof FirebaseAuthInvalidCredentialsException) {
          // Invalid request
        } else if (e instanceof FirebaseTooManyRequestsException) {
          // The SMS quota for the project has been exceeded
        }

        // Show a message and update the UI
      }

      @Override
      public void onCodeSent(@NonNull String verificationId,
        @NonNull PhoneAuthProvider.ForceResendingToken token) {
        // The SMS verification code has been sent to the provided phone number, we
        // now need to ask the user to enter the code and then construct a credential
        // by combining the code with a verification ID.
        Log.d(Constants.TAG, "onCodeSent:" + verificationId);

        // Save verification ID and resending token so we can use them later
        mVerificationId = verificationId;
        mResendToken = token;
      }
    };

    PhoneAuthOptions options =
      PhoneAuthOptions.newBuilder(mAuth)
      .setPhoneNumber(phoneNumber) // Phone number to verify
      .setTimeout(60 L, TimeUnit.SECONDS) // Timeout and unit
      .setActivity(this) // Activity (for callback binding)
      .setCallbacks(mCallbacks) // OnVerificationStateChangedCallbacks
      .build();
    PhoneAuthProvider.verifyPhoneNumber(options);

  }

  private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) {
    mAuth.signInWithCredential(credential)
      .addOnCompleteListener(this, new OnCompleteListener < AuthResult > () {
        @Override
        public void onComplete(@NonNull Task < AuthResult > task) {
          if (task.isSuccessful()) {
            // Sign in success, update UI with the signed-in user's information
            Log.d(Constants.TAG, "signInWithCredential:success");
            FirebaseUser user = task.getResult().getUser();
            // Update UI
            Intent intent = new Intent(OTPActivity.this, SignUpActivity.class);
            startActivity(intent);
          } else {
            // Sign in failed, display a message and update the UI
            Log.w(Constants.TAG, "signInWithCredential:failure", task.getException());
            if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
              // The verification code entered was invalid
              Toast.makeText(OTPActivity.this, task.getException().getMessage(), Toast.LENGTH_SHORT).show();
            }
          }
        }
      });
  }
