Microsoft log in android: FirebaseAuthError, An internal error has occurred. [ INVALID_APP_ID ]

[prggTheProgrammer]

I am trying to intergrate microsoft log in in to my flutter project. It already works on web and ios but it gives FirebaseAuthError, An internal error has occurred. [ INVALID_APP_ID ] when I try it on android.

What I have done:

• Created a new app registration in microsft azure portal
• added a secret
• added the redirect url for android with the hash converted from running gradlew singinreport and the package name
• copied client-id and client-secret to firebase
• Added sha-1 and sha-256 certificate fingerprints to android app in firebase console
• downloaded google-services.json and added it to /android/app

code sample

A test file to test signing in:

import 'package:firebase_auth/firebase_auth.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:firebase_auth_oauth/firebase_auth_oauth.dart';
import 'package:firebase_core/firebase_core.dart';

void main(){
  runApp(MicrosoftApp());
}

class MicrosoftApp extends StatelessWidget{
  @override
  Widget build(BuildContext context) {
    Firebase.initializeApp();
    return MaterialApp(
      title: "Testing microsoft autentication",
      home: MyPage(),
    );
  }
}

class MyPage extends StatelessWidget {
  OAuthCredential? cred;

  Widget build(BuildContext context) {
    return Center(child: TextButton(
      onPressed: signinWithMicrosoft,
      child: Text("Sing in"),
    ),
    );
  }


  void signinWithMicrosoft() async {
    cred = await FirebaseAuthOAuth().signInOAuth(
        "microsoft.com", ["email openid", "profile", "People.Read"],
        {'tenant': 'X-X-X-X-X'});
  }
}

In case you haven't done it, run flutter clean and relaunch. This is what worked for me when I had the same issue.

Thanks I did that a lot of times. But I think it has something to do with the files in .android. Because I managed to get it working with the above sample but not on the real project. I then looked at the diffrences. And I did the same changes in the origninal project and it still doesn't work. I also looked at the changes that were being ignored by .gitignore and I could not find any big change. So it might have to do with the .andoid folder. But thanks for replying.
