问题 I'm building an app using Firebase Notifications where a user can enter their zip code and then receive notifications for specific events happening in their locality. How do I only send notifications to a specific user? I've tried including Zip Code in the Advanced Options sections of Firebase Notifications, but it still sends the notification to all users. 回答1: Seems like Topics is what you are looking for. When the user enters their zipcode you can subscribe them to a topic eg: /topics/zip

问题 In a usual Firebase notification scenario, I understand that my apps should subscribe themselves to certain topics that they want to receive notifications for. However, there are cases in which I want to send notifications to specific devices that are not subscribed to a certain topic. Currently the only way I see of achieving this in Firebase would be to send multiple requests (can easily be a 100+) for each device. Is this the way that this is intended to work or am I missing something?

问题 I can't receive my Firebase Notifications when the app is killed or in background. I signed the APK, and it doesn't work, and when I send my Data notification with JSON the logcat shows me this error: broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE pkg=com.example.paolomazza.firebasedemo3 (has extras) } Given the following Manifest, what could be the cause of this bug? Thanks in Advance <?xml version="1.0" encoding="utf-8"?> <uses-permission

That's really a dumb behaviour. Original post: I can successfully retrieve the bundle from the intent passed by the notificationBuilder to the activity when the app is launched. However, if I kill the app, the notification still works but the GetExtras() from the intent is null. In my
