如何使用FCM向我数据库中的用户发送推送通知？ 安卓

Question

For example, I need to send a notification to a particular user. When the user sends me a trouble-message, I will push a notification which notifies him that the trouble will be fix soon.

Now, I have already created a push notification but even when the user is logged out it can still receive a notification. And when I'm using a different account it can still receive the same notification for the other user.

please help me create a push notification that will send to a specific-signed-in-user. Thank you. (Sorry I'm new here in android.) thank you very much again.

You cannot send to a specific user, you can only send to specific devices. Your server/app needs to handle the logic of users and keys associated with them
