Firebase 数据库指向错误的数据库 URL [英] Firebase Database points to wrong database URL

问题描述

我正在开发 Android 应用并尝试使用 Firebase 数据库.我尝试将数据写入数据库，但没有显示任何内容(通过 Firebase 控制台检查).我在构建中有 Firebase 库:

I am working on an Android app and trying to use Firebase Database. I tried to write data to the Database but nothing was showing up (checked via Firebase console). I have Firebase libraries in the build:

implementation platform('com.google.firebase:firebase-bom:26.2.0')
implementation 'com.google.firebase:firebase-database'

根据 Firebease 控制台，我的 Firebase 数据库 URL 是:

My Firebase Database URL as per Firebease console is :

    https://xxxxxxxx-xxxxxxx-default-rtdb.europe-west1.firebasedatabase.app/

而当我从代码中获得对它的引用时:

whereas when I get a reference to it from the code:

    private DatabaseReference mDatabase;

    mDatabase = FirebaseDatabase.getInstance().getReference();
    Log.i(TAG," Reference is: "+mDatabase.toString());

logcat 显示以下响应:

The logcat shows below response:

    I/Tag:  Reference is: https://xxxxxxxx-xxxxxxx-default-rtdb.firebaseio.com

我在项目中还有 google-services.json 文件，它指向 Firebase 控制台中显示的相同数据库 URL.在我看来，Firebase 在某个我无法看到/配置的地方错误地配置了我的数据库.

I also have the google-services.json file in the project which points to the same database URL shown in the Firebase console. It appears to me that Firebase has misconfigured my database somewhere which I can't see / configure.

有什么我遗漏的吗?

推荐答案

我最近遇到了类似的问题，即使在更新 google_services.json 之后 Firebase URL 也为空，我通过删除我的应用程序的 build 文件夹并再次重建项目来使其工作

I recently faced a similar issue, Firebase URL is null even after updating google_services.json, I got it working by deleting the build folder of my app and rebuilding the project again
