Hello,
I'm trying to set Firebase (the GCM for api 26 and higher) for using airnotifier and i've encountered this error in android studio:
[string/google_app_id] /home/.../platforms/android/res/values/strings.xml [string/google_app_id] /home/.../platforms/android/build/generated/res/google-services/debug/values/values.xml: Error: Duplicate resources
any idea please?
