Firebase身份验证突然停止工作

标签： java android firebase firebase-authentication

我有一个不需要登录的android应用程序，但是我确实启用了匿名登录，以便可以从Firebase检索userID并将其用于记录特定事件。我感觉它只是停止从Firebase检索UID。

我为解决此问题所做的工作如下：

  • 更新了所有依赖项
  • 更新了模拟器
  • 安装了新的模拟器
  • 重新添加了Google服务插件
  • 重新添加了google-services.json文件
  • 更新了Android清单
  • 为了进行测试，我试图创建一个登录活动，该活动通过带有onclicklisterer的按钮来使用户匿名登录。
  • 我已经仔细检查了Android Studio中的“本地历史记录”，以查看是否对代码进行了大的更改，实际情况并非如此。 See screenshot
  • 从Firebase控制台启用和禁用匿名登录。
  • 基于Firebase的documentation重新编写了整个代码。
  • 我基本上已经尝试了每种解决方案

    }

    FirebaseInstanceId.getInstance().getInstanceId()

                @Override
                public void onComplete(@NonNull Task<InstanceIdResult> task) {
                    if (!task.isSuccessful()) {
                        Log.w("This Tag", "getInstanceId failed", task.getException());
                        return;
                    } else {
                        Log.d("This tag", "We need this");
                    }
                }
            });

    swipeDb = FirebaseDatabase.getInstance().getReference().child("Users");
    final FirebaseFirestore db = FirebaseFirestore.getInstance();


    //Anonymous user login to be registered in Firebase
    mAuth = FirebaseAuth.getInstance();
    mCurrentUser = mAuth.getCurrentUser(); // save the UID of the user in users in Firebase without having to log in

    final String UID = mCurrentUser.getUid();
    DatabaseReference currentUserDb = FirebaseDatabase.getInstance().getReference().child("Users").child("UID");
    currentUserDb.setValue(UID); //save the User UID to the Firebase Realtime database



    // Calling to the AdMob API to add advertisements to the banner in the main view.Gotta make that dough
    // Change this to big cards in the future
    final AdView adView = findViewById(R.id.adView);

    final AdRequest adRequest = new AdRequest.Builder()
            //.addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
            .build();

我已经尝试解决这个问题超过一个星期了，没有成功

编辑：

我知道我可以添加侦听器来查看用户是否匿名登录。围绕此问题的整个问题是根本不再登录用户。

Edit2：
