Android authorities: facebook plugin undefined in android manifest

Can’t install because provider name com.facebook.app.FacebookContentProviderundefined (in package io.ionic.sxxxx) is already used by io.ionic.yyyyy]"

This is listed in a few android manifest files

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

on build I get

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

— notice the undefined ----- should I be defining something somewhere? Is there another solution? Basically I have a pair of apps that will not install at the same time on a device because this output is the same. My understanding is undefined should be my facebook id. I do have a variety of values defined in my android strings file.

    <string name="title_activity_main">xxxx</string>
    <string name="package_name">io.ionic.xxxx</string>
    <string name="custom_url_scheme">io.ionic.xxxx</string>
    <string name="fb_app_id">xxxxx</string>
    <string name="facebook_app_id">xxxxx</string>
     <string name="fb_app_name">xxxxx</string>
    <string name="fb_login_protocol_scheme">fbxxxxxx</string>
    <string name="fb_auto_log_app_events_enabled">true</string>
    <string name="fb_advertiser_id_collection_enabled">true</string>
