So I'm writing this in case anyone has any ideas. I cannot get Firebase / Firestore working on my Android emulator with my Flutter project.
At this point, all I'm trying to do is sign in anonymously, and check if a document exists by printing something in the terminal to confirm my app has a connection to Firebase / Firestore in a skeleton app.
firebase_auth: ^3.7.0
cloud_firestore: ^3.4.6
firebase_core: ^1.21.1
Sign in anonymously.
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());
}
...
And call this method to tell me if the document exists (it does).
Future testFirebase() async {
await FirebaseFirestore.instance
.collection("fruit")
.doc("peach")
.get()
.then((document) {
if (document.exists) {
print("exists");
} else {
print("does not exist");
}
});
}
Doing this causes the app to hang. Then after about 5 minutes, I get a slew of error messages

However, on my physical devices running Android Go and Android 12, it works perfectly.
I have:
- Checked Android emulator has Internet connection by opening Chrome / Maps / etc, and they all work fine
- Added
<uses-permission android:name="android.permission.INTERNET"/>and<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />to AndroidManifest main & debug - Reinstalled Windows
- Reinstalled Flutter, Android SDK, Android Studio, VSCode carefully following a guide to ensure everything is configured correctly
- Set
minSdkVersion 22 - Tried different apps with different Firebase projects (they all fail on the emulator but work on the real device)
- Tried Flutterfire CLI and manual config
- Created various emulators with various hardware profiles and versions of Android (Play, non Play, various API levels)
- Ensured "Anonymous Signin" is enabled in Firebase
- Set Firestore rules to allow everything if
request.auth != null - Checked network settings in Windows to allow Internet access for emulator, but the emulator works fine with all other apps
- Tried with firewall on / off & allowed adb.exe full access
- Changed emulator settings to good signal, full network, charging, plugged in, etc.
- Added
android:usesCleartextTraffic="true"to AndroidManifest
And bearing in mind, the physical device works perfectly from from the start without me having to do much of anything. But after reading Stack Overflow for days, I'm at a loss.
If anyone has any ideas that I haven't tried, please do let me know :) Thanks.

I had the same issue. Firebase components were working with a huge delay. I had to install earlier emulator version. The problem occured only on my old laptop, my PC was unaffected.
