问题 I've created a service in my application that listens for push notifications from GCM. The service's OnMessage method gets called correctly in all scenarios that I've tested: app running in foreground, app running in background and app not running. However, when the app is not running, the code is throwing a NullReferenceException when I try to resolve dependencies with Mvx.Resolve .

问题 I have made an implementation which i can create passes for apple wallet. Once the device registers with server will push token unique for this device or will change eventually in future? If yes, what are the reasons for that? 回答1: Yes - to help with privacy, the push tokens are regularly rotated - this may occurs at random, or with changes in hardware (user transferring to a new phone), or often with iOS upgrades. Your web-service API implementation will see this as a new registration

When the app is in background/closed and push notification is sent from firebase, notification pops up in the devices. On clicking that notification from the tray my application starts run, but the control is not entering into fcm.onNotification().
