I am trying to update score using Google Leaderboards, for using Leaderboards I have to use Google SignIn API, my code is copied from https://developers.google.com and i have followed all the steps, created sha1 using:
keytool -exportcert -alias androiddebugkey -keystore <path-to-debug-keystore> -list -v
and put the APP ID in manifest file using:
<meta-data android:name="com.google.android.gms.appstate.APP_ID" android:value="@string/app_id" />
<meta-data android:name="com.google.android.gms.games.APP_ID" android:value="@string/app_id" />
but still unable to Sign In, it's been a month I am trying different approaches, but unable to pin point the exact problem, that's why I need your help.
You have to create client id in google developer console with sha1 key and the package name of ur project..
