Using Google Cloud Messaging in the Motorola ET1



I'm trying to create an app that listens to notifications sent from a Google Cloud Messaging service. This app is being developed with Xamarin.Android and with the help of PushSharp (Redth/PushSharp · GitHub). I've sucessfuly ran this app in many devices but so far I've been unable to do so in the Motorola ET1. Everytime I run the app an error occurs with the following message: "Device does not have package".


Can this package be installed separately on the device? Or is there no possibility of running applications on this device that depend on that package?
