Woof, yeah, that looks related to some firebase plugin. First thing I would try is updating the SDKs you have installed. If you’re managing things through Android Studio, just open up your preferences, go to Appearance & Behaviour/System Settings/Android SDK. Then look for something call “Play Services” under the SDK tools tab.
thanks that’s helped but I have another error

Typically anything you see like that means you’re missing some support libraries for your project. You have some options here. You can either install a cordova-android plugin for support libraries, or update your cordova-android release to the latest 9.0 which should also fix this.
