Question

我正在尝试从我的Android应用程序向Firebase Firestore添加文档。这是我目前拥有的代码。

FirebaseFirestore db = FirebaseFirestore.getInstance();


Map<String, Object> newuser = new HashMap<>();
        newuser.put("Username",username);
        newuser.put("Password",password);
        newuser.put("Nickname",userNickname);
        newuser.put("Code", "ffff");
        newuser.put( "Othercode", "ffffffff");
        newuser.put("Age", "0");
        
        //Point 1

        db.collection("Users").document(username).set(newuser)
                .addOnSuccessListener(new OnSuccessListener<Void>() {
                    @Override
                    public void onSuccess(Void aVoid) {
                        //Point 2
                    }
                })

                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        //Point 3
                    }
                });
//Point 4

当我运行此代码时，它将到达Point 1和Point 4，但永远不会到达Point 3或Point2。我是android和java的新手，所以我不确定Logcat中的含义是什么：< / p>

它正在运行，但是突然停止工作，所以我不确定我做了什么。如果您需要更多代码，我也可以提供。预先谢谢你！

Answer 1

您可能需要从正在使用的当前AVD中清除数据，然后尝试运行它。

我认为AVD互联网工作不正常，或者正在运行太多，因此当我擦除数据时，此问题得以解决。我不认为这会在真实设备上发生，但我不确定。希望这对遇到此问题的任何人都适用。

添加Firestore文档不会失败或成功
