title: how to continue to receive GCM notification when app killed from app tray in Ionic 2
body: <p>I am a newbie in Ionic 2, I have developed an app where I use FCM push notification in Android, and I am able to receive notification when app is in foreground or in background. But I am not able to receive notification when app is removed from background. Is there a way to run <code>gcmListenerService</code> &amp; <code>gcmBroadcastReceiver</code> from <code>cordova</code> as the native plugin broadcaster does not serves the purpose.</p>
