Google Sign-In requestIdToken returns null

Question

I forked this google sample project and ran the android signin.

I set up the options in the google developers console and got a client id, but when running the project the id token comes up null.

The complete code is here
This code requests the id token.

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.server_client_id))
            .requestEmail()
            .build();

Am I missing something in the setup, any suggestions.

Here is the Log

Post your 2 build.gradles files, and are you sure your applicationId in your app the same as the package name created at `http://console.developers.google.com`, the Google's sample project's `com.google.samples.quickstart.signin` — BNK, Dec 05 '15 at 01:09
@BNK I added the package name 'com.google.samples.quickstart.signin' in the OAuth 2.0 client ID creation page in developers console and added my sha1 debug fingerprint. — JosephK, Dec 05 '15 at 01:31
Pls open your `google-services.json` file and make sure "package_name" is "com.google.samples.quickstart.signin" — BNK, Dec 05 '15 at 01:42
Moreover, you can refer to my working sample project at https://github.com/ngocchung/GoogleSignInDemo. Please note that you should customize it with your `applicationId` (`packagename`) and your `google-services.json` file (Pls read `https://developers.google.com/identity/sign-in/android/start-integrating`) — BNK, Dec 05 '15 at 01:47
The 'package_name' is 'com.google.samples.quickstart.signin', project id and project number also match the info on developer console. — JosephK, Dec 05 '15 at 01:49
@BNK I tried your project and the google sample project on two different devices and still id token is coming up null and GET_TOKEN:success:false in the log. could you run the app and see if it works on your end. Thanks. — JosephK, Dec 07 '15 at 18:26
Of course, it works :). Pls wait, I'll post it when I have my PC. — BNK, Dec 07 '15 at 21:59
Here is the logcat info `12-08 08:28:12.871 28960-28960/com.example.googlesignindemo D/IdTokenActivity: onActivityResult:GET_TOKEN:success:true` `12-08 08:28:12.871 28960-28960/com.example.googlesignindemo D/IdTokenActivity: idToken:eyJhbGciOiJSUzI1NiIsImtpZCI6IjFiZmMzODRlZGZh....VXZnL0FBQUFBQUFBQUFJL0FBQUFBQUF...yIsImxvY2FsZSI6ImVuIiwibmFtZ...akQSGqf-pmGfdFVMAIBjgSV4FfY71ya2-58IU0pQ...JjN3-mWGA` — BNK, Dec 08 '15 at 01:27
The `OAuth 2.0 client ID` you got, is its Type `Web application` or `Android`? — BNK, Dec 08 '15 at 01:34
Thanks @BNK for checking. I must have something wrong with the setup but I followed all the steps. The client ID is for android, I will post the google-services.json file with some info blocked out. — JosephK, Dec 08 '15 at 01:40
Make a new ID and choose its type `Web application`. You can find in `strings.xml` file the following content `` — BNK, Dec 08 '15 at 01:43
At `https://developers.google.com/identity/sign-in/android/start`, step#, you also find that `Open the Credentials page. Click Add credentials > OAuth 2.0 client ID. Select Web application. Click Create.` — BNK, Dec 08 '15 at 01:44
I see your .json file, don't use `"client_id": "604...430-uho...slp......v2l........d9...ps.g.....leu........com"` for requestIdToken, use `a valid Web OAuth 2.0 Client ID` as my above comments — BNK, Dec 08 '15 at 01:51
Thank you @BNK it works with the web client id. plz submit an answer and i will accept — JosephK, Dec 08 '15 at 02:00
Could you please help me with my issue, i spend some days trying to solve it... I use the same code, but finally when i retrive tokenId from google api, i get a String tokenId = <857 chars>... ?? If i tryed to validate it googleapis.com/oauth2/v3/tokeninfo?access_token= <857 chars response> i all the get 'error_description": "Invalid Value' ... How are you make a validation of your response?

As I have commented and as Google's documentation, you should use "Web application" type Client Id, instead of "Android" type Client Id.

As the following screenshot:

My app is not a web application, why should I use web client id?! Google is a silly snob... – doctorram Oct 02 '19 at 02:37
In my case I'm using web client ID. But still getting error. When I remove this line requestIdToken(getString(R.string.server_client_id)) it works but getIdToken() returns null – Sujith S Manjavana Jun 05 '21 at 09:14

Use "default_web_client_id" in GoogleSignInOptions

 GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestIdToken(getString(R.string.default_web_client_id))
                .requestEmail()
                .build();

It works perfectly.
