所以我写这篇文章是为了以防万一有人有什么 idea .我不能让Firebase/FiRestore在我的Android模拟器上与我的Ffltter项目一起工作.
在这一点上，我要做的就是匿名登录，并通过在终端中打印一些东西来判断文档是否存在，以确认我的应用程序是否在骨架应用程序中连接到Firebase/FiRestore.
firebase_auth: ^3.7.0
cloud_firestore: ^3.4.6
firebase_core: ^1.21.1
匿名登录.
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
await FirebaseAuth.instance.signInAnonymously();
runApp(const MyApp());
}
...
并调用此方法来告诉我文档是否存在(确实存在).
Future testFirebase() async {
await FirebaseFirestore.instance
.collection("fruit")
.doc("peach")
.get()
.then((document) {
if (document.exists) {
print("exists");
} else {
print("does not exist");
}
});
}
这样做会导致应用程序挂起.然后大约5分钟后，我收到一系列错误消息

然而，在我运行Android Go和Android 12的实体设备上，它运行得非常完美.
我有:
- 通过打开Chrome/Maps/etc判断Android仿真器是否有互联网连接，它们都工作正常
- 在androidManifest主调试中添加了
<uses-permission android:name="android.permission.INTERNET"/>和<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />(&A) - 已重新安装Windows
- 已重新安装Ffltter、Android SDK、Android Studio、VSCode，请仔细按照指南进行操作，以确保一切配置正确
- 套装
minSdkVersion 22套 - 用不同的Firebase项目try 了不同的应用程序(它们在模拟器上都失败了，但在真实设备上可以工作)
- try 了Flutterfire CLI和手动配置
- 创建了具有各种硬件配置文件和Android版本(Play、Non Play、各种API级别)的各种模拟器
- 已确保在Firebase中启用"匿名登录"
- 将FiRestore规则设置为Allow Everything If
request.auth != null - 已判断Windows中的网络设置以允许模拟器访问互联网，但模拟器与所有其他应用程序工作正常
- try 打开/关闭防火墙并允许完全访问adb.exe(&A)
- 已将仿真器设置更改为良好信号、完全网络、充电、已插入等.
- 将
android:usesCleartextTraffic="true"个添加到Android list
请记住，物理设备从一开始就工作得很好，而我不必做很多事情.但在阅读了Stack Overflow几天后，我不知所措.
如果任何人有任何我没有try 过的 idea ，请务必让我知道:) 谢谢.
