I get this error: Error: "GoogleAuth" plugin is not implemented on android

[alessandrolombardini]

I'm going crazy, I can't find a way to fix it. Does anyone know how to do it?

[chitkosarvesh]

I have the same problem! Please help!

[handihow]

same

[handihow]

Okay, I resolved this issue
I had to update Capacitor to version 3
https://capacitorjs.com/docs/updating/3-0
After I took all the steps, the error disappeared.

[kevinfavv]

Same problem,
My capacitor is already in 3.0.0, and the GoogleAuth class is not loaded.
Any informations?

[handihow]

yes, you should remove the import of the Google Auth plugin of the MainActivity.java

https://capacitorjs.com/docs/updating/3-0#switch-to-automatic-android-plugin-loading

this means you can comment out / remove the import com.codetrix.....

and also the code inside the BridgeActivity

Make sure that you have installed "@capacitor/cli": "^3.0.1" in the dev dependencies

When you run npx cap sync android, you will see that capacitor now installs all the plugins automatically

[LuisMSotamba]

I followed all the steps for update from capacitor 2 to 3, but I get the same problem. "GoogleAuth.init()" is not implemented on android.

[FabioGoncalves]

Yeah, I am having the same problem, and if I remove the init(), it keeps stuck in google form...

[DercilioFontes]

"GoogleAuth.init()" is only for WEB (https://github.com/CodetrixStudio/CapacitorGoogleAuth#migrate-from-2-to-3).

For Android and iOS is not necessary. I added a condition for checking that:

import { Device, DeviceInfo } from "@capacitor/device";
import { GoogleAuth } from "@codetrix-studio/capacitor-google-auth";

... 

const onSignInGoogle = async () => {
    try {
      const deviceInfo = await Device.getInfo();

      if ((deviceInfo as unknown as DeviceInfo).platform === "web") {
        await GoogleAuth.init();
      }
      const googleUser = (await GoogleAuth.signIn());
 ...

For the original issue, it worked as commented here: #110

[FabioGoncalves]

I am doing just like that, but after I choose my Google account, it's always stuck, like this

[DercilioFontes]

@FabioGoncalves, what are the logs on the Android Studio or Chrome device Dev tools?

[emtiajium]

const deviceInfo = await Device.getInfo();

After doing that I'm getting the error: "Device" plugin is not implemented on android

[DercilioFontes]

@emtiajium ,

Follow the guide for upgrading Capacitor. It will solve that.

https://capacitorjs.com/docs/updating/3-0

Comment or remove the onCreate method override. It is not necessary anymore.

Switch to automatic Android plugin loading

In Capacitor 3, it is preferred to automatically load the Android plugins. In MainActivity.java, the onCreate method can be removed. You no longer have to edit this file when adding or removing plugins installed via npm.

 public class MainActivity extends BridgeActivity {
//    @Override
//    public void onCreate(Bundle savedInstanceState) {
//        super.onCreate(savedInstanceState);
//
//        // Initializes the Bridge
//        this.init(savedInstanceState, new ArrayList<Class<? extends Plugin>>() {{
//            // Additional plugins you've installed go here
//            add(Plugin1.class);
//            add(Plugin2.class);
//       }});
//   }
 }

But for using the GoogleAuth, you need to register it like that:

import android.os.Bundle;
import com.getcapacitor.BridgeActivity;
import com.codetrixstudio.capacitor.GoogleAuth.GoogleAuth;

public class MainActivity extends BridgeActivity {

     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

        registerPlugin(GoogleAuth.class);
     }

}

I followed all the steps but I get an error "c.NativePromise is not a function". Please help find solution to this issue and if possible those who have it work can share their knowledge on the steps and possibly share an example github repo to reference. Thanks in advance

[DercilioFontes]

@codemickey78,

Give more info about what you are trying to achieve. Where and when does this error happen?

[codemickey78]

@DercilioFontes

I'm using Ionic Capacitor 3 for my app and I need to authenticate user with Google SignIn. At first, I was using the GooglePlus capacitor plugin which wasn't working but later found out that the CodetrixStudio/CapacitorGoogleAuth was best to integrate.

I used that in my project which worked on iOS without any error but fails on Android with error "c.NativePromise is not a function" which happens to log an error "window.Capacitor.triggerEvent is not a function"

[DercilioFontes]

@codemickey78 ,

I don't know. The best I found was that about dev environment using https, but working with http.

ionic-team/capacitor#4056

[FabioGoncalves]

@DercilioFontes This works on Chrome, but on android was not working: this was like, 4 days ago.
Today: Is already working :o, maybe I should've waited 💯
Thank you, for all the supp guys!

[codemickey78]

@FabioGoncalves can you please help me solve it?
this is the error I'm getting.
👇🏽👇🏽👇🏽

[FabioGoncalves]

Do you have capacitor 3?
Did you follow all the instructions, put the server_client_id in strings.xml, the google-signin-client_id in index.html and added the plugin in the capacitorConfig.json?

Btw, I answered here #109

Btw, I answered here #109

I'm also facing the issue, did everything, it works fine for the Web app and neither does for the Android app. I guess it happens because of the "Authorized JavaScript origins", as it does not allow to set the IP address.

[codemickey78]

@FabioGoncalves Yes, I'm using Capacitor 3, I have configured everything too.
Check them here👇🏽

👇🏽

@emtiajium were you able to make it work?

[FabioGoncalves]

Well, are you sure that the error that you showed is about this plugin? I didn't have any error like that one...

That server_client_id, is this one?

You added the SHA1 in firebase and enabled the google log in?

If so, I am not seeing the problem... the same thing was happening to me, but at least I could choose a google account and then I was stuck in that img that I inserted and that you have to make it too.

[emtiajium]

@FabioGoncalves Yes, I'm using Capacitor 3, I have configured everything too.
Check them here👇🏽

👇🏽

@emtiajium were you able to make it work?

I added the key in the XML file that is generated by the Firebase (Android client for com.x.y (auto created by Google Service))
BTW, used the other key, (Web client key) for the web app.

So, web app is working and Android app is not

[FabioGoncalves]

You have to use the same Web client key!!

[emtiajium]

You have to use the same Web client key!!

Tried with the web client key at the index.html, strings.xml and capacitor.config.json but it produced the same result. When I click the sign-in button, I am able to select the Google user, but after that, it returns me nothing (from the GoogleAuth.signIn())

I couldn't figure it out!

[codemickey78]

Finally I solved it 🥳🥳🥳
But when I select the account, I'm stuck at confirmation popup to allow user. On clicking the "Allow" button it loads the same popup again.

[FabioGoncalves]

Yeah, I was in the same situation, but after 2-3 days when I went check again, it was working... xD

I did not get CodetrixStudio/CapacitorGoogleAuth to work in my project . Instead, I had to change to Ionic Google Plus https://ionicframework.com/docs/native/google-plus. I followed all the instructions and its worked in my Angular-Ionic project. I am using capacitor.

Summarizing it. Install the needed packages and sync it.

npm install cordova-plugin-googleplus
npm install @ionic-native/google-plus
ionic cap sync 

Inside app.module import GooglePlus
import { GooglePlus } from '@ionic-native/google-plus/ngx';
and insert it as provider.

In you login page, insert:

import { GooglePlus } from '@ionic-native/google-plus/ngx';

constructor(private googlePlus: GooglePlus) { }

...

this.googlePlus.login({})
  .then(res => console.log(res))
  .catch(err => console.error(err));

See https://github.com/EddyVerbruggen/cordova-plugin-googleplus#usage for replace empty object inside googlePlus.login()

Create credentials in Console google https://console.cloud.google.com/

You need SHA-1 certificate thumbprint. For this step, run powershell and go to the directory: C:\Users\your_name_user\.android. Inside this folder, you will find debug.keystore file.
Run the following command: keytool -keystore debug.keystore -list -v
You get the SHA-1 certificate fingerprint needed for create the google's credentials.

Once you had create the credentials and you had setup your project, run the project on android emulator or physical device and test it.

[codemickey78]

Well I have it working on android now with CodetrixStudio/CapacitorGoogleAuth 🥳✌🏽
Ready to launch my app 🚀🔥

[FabioGoncalves]

What have you done? Just waited? 😅

[codemickey78]

What have you done? Just waited? 😅

@FabioGoncalves I tested it on an emulator and it worked!

[FabioGoncalves]

@codemickey78 nice! I am glad you could make it!

[codemickey78]

@FabioGoncalves my app is live now on AppStore & PlayStore
still waiting for Google to approve it but it available on Apple

@brightchip, have you done that?

[brightchip]

I kept the Main Activity default as It says "Cannot resolve symbol 'codetrixstudio'"
@DercilioFontes

[DercilioFontes]

@brightchip, have you updated to Capacitor 3 and capacitor-google-auth 3?

"@capacitor/cli": "^3.0.1", "@codetrix-studio/capacitor-google-auth": "^3.0.1",

And used as:
`import { GoogleAuth } from "@codetrix-studio/capacitor-google-auth";`

- https://www.npmjs.com/package/@codetrix-studio/capacitor-google-auth
- https://capacitorjs.com/docs/updating/3-0

When building for Android, it will import it automatically.

[brightchip]

Yes I just installed it recently
"@capacitor/android": "^3.0.1", "@capacitor/cli": "^3.1.1", "@capacitor/core": "^3.0.1", "@capacitor/ios": "^3.0.1", "@chrisbielak/svg-module": "^0.1.8", "@codetrix-studio/capacitor-google-auth": "^3.0.2",

[brightchip]

Oh wait. Thanks a lot! It got fixed I just have to run npx cap update android

@LuisMSotamba Thank you for your solution. It is much easier than with CodetrixStudio/CapacitorGoogleAuth

[rafraph]

I'm using ionic with capacitor for my project and in my case the gmail sign in worked with in following cases:

• ionic simulator
• android simulator
• run from android studio on real device (with the play button)
• create signed app and install it on real device with bundletool

But - when I put it in the play store and install it on real device for internal test, the sign it not working. I can choose the gmail account for the sign it, but after I clicked on this account it just return to my page without continue to complete the sign in.
Can it be related to "OAuth consent screen" in GCP?

[rafraph]

It took me a lot of time to fix this issue, so I will summarize here what works for me, to save time to other good people. I also used the information from this page especially from @FabioGoncalves and @DercilioFontes - thanks!
MainActivity.java

import android.os.Bundle;
import com.getcapacitor.BridgeActivity;
import com.codetrixstudio.capacitor.GoogleAuth.GoogleAuth;

public class MainActivity extends BridgeActivity {
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
        registerPlugin(GoogleAuth.class);
     }
}

index.html
add meta tag with the client_id. In my case I upload the application to play store with upload key, and google signed the app with signing key, so I need to use the SHA-1 of the signing key. So I need to go to my app in the google clound platform (GCP) -> API & Services -> Credentials and create new credentials for OAth 2.0 Client IDs. The type is Android, the package name is from AndroidManifest.xml and the SHA-1 is from my app in the google developer console -> Setup -> App Integrity -> and copy the SHA-1 of the App signing key certificate. Now you create the correct credentials. Copy the client ID that generated and use it in index.html like this:
<meta name="google-signin-client_id" content="************-**************************************.apps.googleusercontent.com">
replace the *** with your real client_id.

strings.xml
add the server_client_id. This is the client id of the web client in GCP-> API & Services -> Credentials. Add it like this:
<string name="server_client_id">**************-*************************************.apps.googleusercontent.com</string>

login page
The call for GoogleAuth.init(); is not needed for Android

I am doing just like that, but after I choose my Google account, it's always stuck, like this

you solved?

Underrated comment for newbies like myself

[Mohammad-Ismail-DEV]

@codetrix-studio/capacitor-google-auth
isn't working it's giving me an error with the message "Something went wrong".

[Rufai-Ahmed]

I have this same problem, but with version 5

[rasult22]

Guys do not forget adding this to your capacitor config: plugins: { GoogleAuth: { scopes: ['profile', 'email'], serverClientId: xxxxxxxxxxxxxxxxxxxxxxxxxi.apps.googleusercontent.com', forceCodeForRefreshToken: true, } },

[Rufai-Ahmed]

The issue with mine was that the package.json wasn't updating properly as I was installing the dependencies. So, it's a monorepo with a general dependency, and then ionic kinda generates its package.json and the dependencies' plugin wasn't updating there
