Google authentication code 12501

Question

I use these following lines of code to integrate with G + android embed.

In the build.gradle application:

compile 'com.google.android.gms:play-services-auth:8.4.0' compile 'com.google.android.gms:play-services-plus:8.4.0'

In MainActivity:

  GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) .requestEmail() .requestIdToken("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.com") .requestProfile() .build(); AppCompatActivity appCompatActivity = (AppCompatActivity) context; googleApiClient = new GoogleApiClient.Builder(context) .enableAutoManage(appCompatActivity, this) .addConnectionCallbacks(this) .addApi(Auth.GOOGLE_SIGN_IN_API, gso) .addApi(Plus.API) .build(); 

I also added the google-services.gson file at the application level. I also made a web application and used client-id for the requestIdToken () parameter.

requestIdToken (webapp client identifier).

After writing this code, still I get status code = 12501 in the response and tokenId = null.

I also read this link . But can not find any solution.

You need to add credentials for both your signed and client_id debugging in google-services.json as follows:

 "oauth_client": [ { "client_id": "<your-client-id>", "client_type": 1, "android_info": { "package_name": "<your-package-name>", "certificate_hash": "<hash>" } }, { "client_id": "<your-client-id-2>", "client_type": 1, "android_info": { "package_name": "<your-package-name-2>", "certificate_hash": "<hash-2>" } } ]

This may be due to the release of Sha-1 and Sha-256 and mismatch of debug keys.

Add all three keys (Debug: Sha-1, Release: Sha-1 and Sha-256) to the Firebase console, then reload json and replace.

It works great for me.

Sometimes OAuth 2.0 client identifiers (web application key) may not match

Make sure you include the following in your manifest file:

 <application ...> <meta-data android:name="com.google.android.gms.games.APP_ID" android:value="@string/app_id" /> <!-- if app is a game --> <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
