title: PushyNetworkException thrown on Pushy.Register
body: <p>I am trying to get pushy from pushy.me to work with Xamarin. I have created a Bindings Library for Pushy and it builds fine. On Pushy.Register(context) I get an exception thrown. I can't figure out what is causing the exception has anyone else tried to implement this into xamarin and were successful or have any ideas what could be going wrong.</p>
  
  <p>The eception is thrown on </p>
  
  <p>JNIEnv.GetString(JNIEnv.CallStaticObjectMethod(class_ref,id_register_Landroid_content_Context_, __args),JniHandleOwnership.TransferLocalRef);</p>
  
  <p>Thanks</p>
