android Fb Like Button via undefined

Question

I am using facebook SDK 4.14.1. After clicking on like button, it redirects me to Like page. It says "via undefined" instead of my application name. What I did wrong?

Answer 1

Another solution is to add Facebook Application Name in the manifest

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

Answer 2

Find the solution. Should call:

FacebookSdk.setApplicationId(getString(R.string.facebook_app_id));
FacebookSdk.setApplicationName("App Name");
