[Android] Is it possible to create my own implementation of GcmListenerService disabling the one shipped with this plugin?

[buttifabio]

I have a Xamarin.Forms project for an iOS/Android app. I correctly installed this plugin

I would like to customize the behavior of the PushNotificationGcmListener shipped in this plugin, but i can't do it if I use the plugin as a NuGet Package. What should i have to do? If i create my own class with extends GcmListenerService i obtain a doubled push handling? Is there a way to disable the service created by this plugin?

I tried unistalling the NuGet package and importing directly the android code of the plugin (except the PushNotificationGcmListener class), but i have some problems with assemblies references (CrossPushNotification, IPushNotificationListener, ecc). How could import your plugin without NuGet in my Android project only?

Thank you for your help
