Answer 1

In platforms -> android ->project.properties file change

from

cordova.system.library.3=com.facebook.android:facebook-android-sdk:4.+

to

cordova.system.library.3=com.facebook.android:facebook-android-sdk:4.25.0

Answer 2

Remove all plugins then have dependencies on cordova-plugin-compat, listed here: https://cordova.apache.org/news/2017/11/10/plugins-release.html

Remove plugin itself and re-install platform.

cordova plugin rm cordova-plugin-compat --force cordova platform rm android cordova platform add [email protected]

This should help.
