我在 Unity 2020.3.0.f1 上创建了一个简单的应用程序,集成了 Firebase sdk 7.1.0。我基本上是在对 firebase 进行简单的读写。尽管 apk 构建 100% 成功,但它在 Unity 编辑器中运行良好,但在移动构建中运行不佳。
操作系统:Ubuntu 20.04(LTS)。
这是我的简单代码
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Firebase.Database;
using TMPro;
public class firebase_script : MonoBehaviour
{
DatabaseReference reference;
string text_place;
public TextMeshProUGUI text;
// Start is called before the first frame update
void Start()
{
reference= FirebaseDatabase.DefaultInstance.RootReference;
}
public void get_updates(){
reference.Child("plant").GetValueAsync().ContinueWith(task => {
if(task.IsFaulted){
Debug.Log("Failed to fetch Value");
}
else if(task.IsCompleted){
DataSnapshot snapshot =task.Result;
text_place=snapshot.Child("moisture").Value.ToString();
}
});
}
// Update is called once per frame
void Update()
{
text.text=text_place;
}
}
编辑:当我看到 logcat 时,我发现 Firebase 应用程序初始化失败,但在 Unity 编辑器中工作时看不到此类错误,并且该应用程序在 Unity 编辑器中运行良好,但在 Android 设备中则不然

我遇到了同样的问题,即 google-services.json 未加载(Unity 2021.1.4f),并花了很长时间寻找答案,但没有找到有效的建议解决方案。最后,我尝试使用手动创建的 AppOptions 手动调用 Firebase.Create() ,并使用从 google-services.json 复制的值。
Firebase.AppOptions options = new Firebase.AppOptions();
options.ApiKey = "XXXXXXXXXXX";
options.AppId = "XXXXXXXXXXXX";
options.MessageSenderId = "XXXXXXXXXXXXX";
options.ProjectId = "my-app";
options.StorageBucket = "my-app.appspot.com";
var app = Firebase.FirebaseApp.Create( options );
这不是一个理想的解决方案,但在该错误得到修复之前一直有效。
