Tag <provider> attribute authorities has invalid character '{' in AndroidManifest.xml using Facebook ShareLink

Question

Though I delete the "{}" braces but it still occurs.

<provider
        android:name="com.facebook.FacebookContentProvider" android:authorities="com.facebook.app.FacebookContentProvider{facebook_app_id}"
        android:exported="true" />

Answer 1

I had the same: the IDE re-inserted the curly braces. I cut the part, restarted Android Studio and pasted it. Then it worked.
