Android-如何限制用户在多个设备上处于活动状态？

Question

I am developing an Android application in which I would like to restrict an user to access only one device at a time.

Lets say, User A is logging in first time using the Android application and from next time,the app logs in automatically using the credentials stored in the local storage.

If the same user is logging in with the web application with the same credentials and changed the password, the mobile application should force the user to login as soon as the password is changed.Even if the mobile application is being active and doing some tasks , it has to be cancelled and force user to login once again.

My idea was to use Push Notification in Mobile app to terminate the session as soon as the user has logged in/changed the password from web application. But the bottle neck is that there is an option in device settings to block the notification.

Please help me to find a way to overcome this.

There is NO option in devices to block Push Notifications. But there is an option to stop an App from showing Notifications in the Device Notification Bar and also there is another option to stop an App from using Data (Internet) in the background (when not in use!). This is a different case with your issue.

Here is how! On your server send message to a user Device using Firebase . You should send Data Messages so as to gain full control and because you do not need to show any notification to a user device. When that message reaches to the user. You should Logout the user. Remember all this happens in the background the user does not notice anything or any notification shown.You can learn more about message types here .
