excuse me, now that we have done app on the web, we have encountered the problem of dropping the line behind the screen of the Android phone. I wonder if apicloud has a third-party service that can be pushed to the customer"s notification bar even if the status of the customer"s message screen. Or is there any other way to solve this problem? Is it mainly because the socket is offline and cannot be pushed to the notification bar of the customer"s mobile phone?
