Update your style.xml file as below, maybe it will work

<resources>
  <string name="facebook_app_id">[APP_ID]</string>
  <string name="facebook_client_token">[CLIENT_TOKEN]</string>
  <string name="fb_login_protocol_scheme">fb[APP_ID]</string>
  <string name="app_name">[APP_NAME]</string>
</resources>
