firebase-cloud-messaging

问题 I use the FirebaseMessagingService to handle incoming notifications. When my app is in the foreground and background the messages are being arrived. When I swipe-out the app, notifications are being arrived. But if I restart my device, notifications are not being arrived until I run my app. In the same way, Telegram and WhatsApp continue receiving notifications after reboot. I have implemented the onNewToken() method and have added logic to send new token to the server but it hasn't helped.

问题 I am assuming that someone has reserved 4:30 now and wants to save it to the server and notify the server from the server at 4:30. I do not want to use the alarm system built into the smartphone. I also watched Firebase cloud function lectures on YouTube and implemented them. And I've also seen CronJobs, which gets into the URL by alarm on time and executes the function. I have to set the time for the user and give an alarm to each individual. 回答1: There is no straight forward way of doing
