Build problems with @mauron85/cordova-plugin-background-geolocation plugin

Could you help me with this error.
I have this plugin name="@mauron85/cordova-plugin-background-geolocation" spec=“3.1.0” in my config.xml:
But I get this error:

Execution failed for task ‘: app: processDebugResources’.

A failure occurred while executing $ ActionFacade
Android resource linking failed
/platforms/android/app/src/main/res/xml/authenticator.xml:2: AAPT: error: resource mipmap / icon (aka mipmap / icon) not found.

Does anyone know why this happens?
Please help.

This is how I’ve set it up. It’s a rather long while since I tested it though, so no guarantees it still works.
