从Firebase通知控制台发送时未收到FCM通知

Question

I am using Firebase notifications in my application. I have performed all steps mentioned in firebase documentaton. I can also receive the registration token inside onTokenRefresh() method. But when I try to send message to my device from Firebase Notification console, It shows status as 'Completed' next to message, but I don't receive anything on my device even when app is in background.

Answer 1

(copy paste from my other answer )

I had this exact problem, the device behavior was somehow weird. some notifications were received, some not.

In the end I found out what was wrong. My device's Sync setting was off. please check that first and don't waste your time like me.

Answer 2

You need to call private void sendNotification(String topic); method from Overriden method public void onMessageReceived(RemoteMessage remoteMessage). then your notification will added to notification bar.

Happy Coding.
