Facebook: Client token must be embedded in your client code

Facebook throws the warm error, how to resolve it?

GraphRequest: Starting with v13 of the SDK, a client token must be embedded in your client code before making Graph API calls. Visit https://developers.facebook.com/docs/android/getting-started#client-token to learn how to implement this change.

I already added to Manifest

  <meta-data
            android:name="com.facebook.sdk.ApplicationId"
            android:value="@string/facebook_app_id" />

Version:

"com.facebook.android:facebook-android-sdk:12.1.0"
