我正在使用以下代碼在Firebase上保存數據。但是數據沒有保存在Firebase中，我該如何解決？

Question

creat_acount_button=(Button)findViewById(R.id.creat_acountID); creat_acount_button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { final String name=username.getText().toString().trim(); String em=email.getText().toString().trim(); String pass=password.getText().toString().trim(); final String phoneNum=phone.getText().toString().trim(); final String loc=location.getText().toString().trim(); final String desc=description.getText().toString().trim(); if (!TextUtils.isEmpty(name)&&!TextUtils.isEmpty(loc)&&!TextUtils.isEmpty(em)&&!TextUtils.isEmpty(pass)&&!TextUtils.isEmpty(desc)) { mProgress.setMessage("Creating Acount"); mProgress.show(); mAuth.createUserWithEmailAndPassword(em,pass) .addOnSuccessListener(new OnSuccessListener<AuthResult>() { @Override public void onSuccess(AuthResult authResult) { if (authResult!=null) { String userid=mAuth.getCurrentUser().getUid(); DatabaseReference curentuserDB=mDatabaseReference.child(userid); curentuserDB.child("UserName").setValue(username); curentuserDB.child("phone").setValue(phoneNum); curentuserDB.child("location").setValue(loc); curentuserDB.child("Description").setValue(desc); mProgress.dismiss(); Intent intent = new Intent(Register.this,Post.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(intent); } } }); } } });

嘗試像這樣添加故障偵聽器，並輸出錯誤（如果存在）：

mAuth.createUserWithEmailAndPassword(em,pass).addOnCompleteListener(task -> {
            //Successful
            if(task.isSuccessful()){
                String userid=mAuth.getCurrentUser().getUid();
                DatabaseReference curentuserDB=mDatabaseReference.child(userid);
                        curentuserDB.child("UserName").setValue(username);
                        curentuserDB.child("phone").setValue(phoneNum);
                        curentuserDB.child("location").setValue(loc);
                        curentuserDB.child("Description").setValue(desc);

                        mProgress.dismiss();

                        Intent intent = new Intent(Register.this,Post.class);
                        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                        startActivity(intent);
            }
            //Error
            else {                
                Log.d("Error", Objects.requireNonNull(Objects.requireNonNull(task.getException()).getLocalizedMessage()));
            }

        }).addOnFailureListener(e -> {
                Log.d("Error", Objects.requireNonNull(e.getLocalizedMessage()));
        });
