我無法使用 email 創建用戶和使用 firebase 的密碼

Question

我正在嘗試使用 email 和密碼創建用戶，如果任務成功，則將其詳細信息存儲在 firebase 數據庫中以供參考，但我不知道會發生什么。 progressDialog 在不創建用戶的情況下保持加載。 這是代碼。 如果有人能幫我解決這個問題，我將不勝感激

private void registerSeller() {
  String sellerName = name.getText().toString();
  String phoneNumber = phone.getText().toString();
  String sellerEmail = email.getText().toString();
  String sellerPassword = password.getText().toString();
  String sellerAddress = address.getText().toString();

  if (sellerName.isEmpty()) {
    name.setError("Please Enter Your Name");
    `enter code here`
    cancel = true;
    name.requestFocus();
  } else if (phoneNumber.isEmpty()) {
    phone.setError("Please Enter Your Phone Number");
    cancel = true;
    phone.requestFocus();
  } else if (sellerEmail.isEmpty()) {
    email.setError("Please Enter Your Email Address");
    cancel = true;
    email.requestFocus();
  } else if (sellerPassword.isEmpty()) {
    password.setError("Please Enter Your Password");
    cancel = true;
    password.requestFocus();
  } else if (sellerAddress.isEmpty()) {
    address.setError("Please Enter Your Shop Address");
    cancel = true;
    address.requestFocus();
  } else {
    loadingDialog.setTitle("Registration Processing...");
    loadingDialog.setMessage("Please wait while we are checking your credentials");
    loadingDialog.setCanceledOnTouchOutside(false);
    loadingDialog.show();
    mAuth.createUserWithEmailAndPassword(sellerEmail, sellerPassword)
      .addOnCompleteListener(new OnCompleteListener < AuthResult > () {
        @Override
        public void onComplete(@NonNull Task < AuthResult > task) {
          if (task.isSuccessful()) {
            final DatabaseReference sellerRef = FirebaseDatabase.getInstance().getReference();
            FirebaseUser user = mAuth.getCurrentUser();
            String sid = mAuth.getCurrentUser().getUid();

            HashMap < String, Object > sellerMap = new HashMap < > ();
            sellerMap.put("sid", sid);
            sellerMap.put("name", sellerName);
            sellerMap.put("phone", phoneNumber);
            sellerMap.put("email", sellerEmail);
            sellerMap.put("password", sellerPassword);
            sellerMap.put("address", sellerAddress);
            sellerRef.child("sellers").child(sid)
              .updateChildren(sellerMap)
              .addOnCompleteListener(new OnCompleteListener < Void > () {
                @Override
                public void onComplete(@NonNull Task < Void > task) {
                  if (task.isSuccessful()) {

                    loadingDialog.dismiss();
                    Toast.makeText(SellerRegistrationActivity.this, "Seller Registered Successfully", Toast.LENGTH_SHORT).show();
                    Intent intent = new Intent(SellerRegistrationActivity.this, SellerLoginActivity.class);
                    startActivity(intent);
                  } else {
                    loadingDialog.dismiss();
                    Toast.makeText(SellerRegistrationActivity.this, "Error Occurred", Toast.LENGTH_SHORT).show();
                  }
                }
              });

        }
      });
  }
}

故障排除的第一步是停止忽略潛在的錯誤。 如果一個Task失敗了，它有一個異常來解釋導致它失敗的原因。 您應該記錄或引發該異常，以找到根本原因：

mAuth.createUserWithEmailAndPassword(sellerEmail, sellerPassword)
  .addOnCompleteListener(new OnCompleteListener < AuthResult > () {
    @Override
    public void onComplete(@NonNull Task < AuthResult > task) {
      if (task.isSuccessful()) {
          ...
      }
      else {
          throw task.getException();
      }
    }
