PlatformException (PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 12500: , null))

Question

The line where is going to crash:

GoogleSignInAccount googleUser = await _googleSignIn.signIn();

What have I tried:

1. I've generated my SH1 key with this command keytool -list -v \ -alias androiddebugkey -keystore ~/.android/debug.keystore
2. Adding SH1 encryption into console.firebase.google.com
3. Re-downloading the google-service.json
4. Copying the debug.keystore from .android to MyProject/android
5. Run in debug and release

6. Adding into android/build.gradle those lines:

   • classpath 'com.android.tools.build.gradle:3.2.1'
   • classpath 'com.google.gms:google-services:4.2.0'

7. Adding into android/app/build.gradle this lines:

   • implementation 'com.google.firebase:firebase-core:16.0.9' under dependencies
   • apply plugin: 'com.google.gms.google-services' on the end of the file.
8. Creating a file named release-signing.properties under my project folder with those lines in it.
   • storeFile=debug.keystore
   • keyAlias=androiddebugkey
   • storePassword=android
   • keyPassword=android

Also, I've searched in ALL StackOverflow question that I could found for this question, and none of them was useful for me.

My pubspec.yaml:

firebase_core: ^0.4.0+1
firebase_analytics: ^3.0.1

cloud_firestore: ^0.11.0+2

firebase_auth: ^0.11.1
google_sign_in: ^4.0.1+3

rxdart: ^0.22.0

Auth class:

class AuthService {
  final GoogleSignIn _googleSignIn = GoogleSignIn();
  final FirebaseAuth _auth = FirebaseAuth.instance;
  final Firestore _db = Firestore.instance;

  Observable<FirebaseUser> user;
  Observable<Map<String, dynamic>> profile;
  PublishSubject loading = PublishSubject();

  AuthService() {
    user = Observable(_auth.onAuthStateChanged);
    profile = user.switchMap((FirebaseUser user) {
      if (user != null) {
        return _db
            .collection('user')
            .document(user.uid)
            .snapshots()
            .map((snap) => snap.data);
      } else {
        return Observable.just({});
      }
    });
  }

  Future<FirebaseUser> googleSignIn() async {
    loading.add(true);
    GoogleSignInAccount googleUser = await _googleSignIn.signIn();
    GoogleSignInAuthentication googleAuth = await googleUser.authentication;
    // FirebaseUser user = await _auth.signInWithGoogle(
        // accessToken: googleAuth.accessToken, idToken: googleAuth.idToken);
    final AuthCredential credential = GoogleAuthProvider.getCredential(
      accessToken: googleAuth.accessToken,
      idToken: googleAuth.idToken,
    );
    FirebaseUser user = await _auth.signInWithCredential(credential);
    updateUserData(user);
    print("Sign in" + user.displayName);

    loading.add(false);

    return user;
  }
}

Main class:

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  AuthService authService = AuthService();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blueGrey,
      ),
      home: Scaffold(
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              MaterialButton(
                child: Text("Log in with Google"),
                color: Colors.blueGrey,
                textColor: Colors.deepOrange,
                onPressed: () => authService.googleSignIn(),
              ),
              MaterialButton(
                child: Text("LogOut"),
                color: Colors.redAccent,
                textColor: Colors.purple,
                onPressed: () => authService.signOut(),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

Now if any of you could point me in the right direction I would be very grateful.

Here are some stackoverflow links that I've tried already:

1. Google sign in doesn't work after release of flutter app
2. Flutter and google_sign_in plugin: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)
3. Google Sign In error 12500

I didn't have luck with any of them, please let me know what do you think and how can I fix it.

Answer 1

The OP, @Mircea, specifically mentioned error 12500. This is how I overcame that error:

I have spent the last few days running into the same problem. I refactored my code dozens of times, added break points, reset the SHA-1, SHA-256 and did just about every other 'code' based solution I could find. I was constantly running into the error:

E/flutter (11935): [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 12500: , null)

I was losing my mind so I decided to start with fresh eyes and move slowly through solutions one more time. I noticed an obscure post nestled deep in a thread that mentioned something about having a support email. It was not until I added a said support email that things "magically" started working. I've attached a screenshot below of the Firebase settings for my project.

Answer 2

You need to complete " Oauth consent screen "

I went to this page ( https://console.developers.google.com/apis/credentials ) Do not forget to select your project on the list (top left). Then go on "Oauth consent screen"

I filled the application logo and the application homepage link and aplication privacy policy link (with the project.firebaseapp.com) and saved.

Now it's working, I can login.

This must be explained in the documentation. People are going to be crazy and to don't try flutter with this kind of lack of documentation.

Answer 3

In my case, I have not enabled Google Sign In method.

Answer 4

将您的 émilator 更改为另一个如何支持 google play 商店

Answer 5

我还尝试了几乎所有可以从 Internet 搜索的答案。所以我决定尝试 ios 端然后它仍然给我错误“403 受限客户端”。然后我确定它是服务器端问题。最后我发现忘记设置支持电子- Google Developers Console > API 和服务 > 证书 > 用户同意屏幕 链接中的邮件地址，此选项也在您的 Firebase 项目设置中。设置后一切正常。希望这对您有所帮助。

Answer 6

After following all the steps mentioned in the documentation, even I was facing the same issue. One thing worked for me is adding the support email in the setting page of firebase console

Answer 7

Go to the API & Servcies page of your google account and make sure to select the project of your interest in the top left corner as shown below

Make sure you have the support email ID entered in the above

And all the below fields must have a value

Try logging in now, it will work!

Answer 8

I ran exatly into the same issue, what solved the issue for me was to add a SHA-256 fingerprint additionally to the SHA-1

as mentioned here -> Flutter and google_sign_in plugin: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)

Hope that works for you too!

Answer 9

had the same issue was using visual studio when I changed to android studio it worked. I guess because I am signed into firebase with android studio i wander if i can do the same with VS oh well hopefully this helps someone

Answer 10

I faced the same issue, I resolved it by adding the debug / release SHA1 and SHA256 certificate fingerprint using Keytool

Release

keytool -exportcert -list -v -alias <your-key-name> -keystore <path-to-production-keystore>

Debug

keytool -list -v -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

More details here: https://developers.google.com/android/guides/client-auth

Answer 11

Just to add to this already huge list of ideas. I had to add myself as a test user under the OAuth Consent Screen.

Answer 12

In my case, the problem was due to incompatible emulator. The emulator didn't had playstore.

I created a new AVD which has playstore in it. And then it worked!

Reference to create new emulator with Playstore

Also, verify that you have added the SHA1 key on firebase console.

Answer 13

In my case, I forgot to enable To add users manually, enable Email/Password as a sign-in method enter image description here

Answer 14

Go to Play store and Search for "App Integrity"

Google play store app integrity

Then Copy the SHA Keys and Add into the Firebase or Google Cloud signing keys.

and then you are good to go.

worked for me.

Answer 15

POSSIBLE CASE 2023

I had to face this problem too, during testing everything was working fine, but when I changed my project (actually build.gradle was the problem) to release mode the sign in process stopped to work as it was used to.

I tried to fill all the fields on Oauth consent screen ( https://console.developers.google.com/apis/credentials ), but nothing changed.

I also tried to check my SHA on Firebase, but both SHA-1 and SHA-256 were there.

As last resource I wanted to check my current SHA so in app/android folder I runned: ./gradlew signinReport and I found out that the SHA were changed.

So I uploaded them on Firebase and now everything is working fine.

In the end, check the SHA twice.
