  • Which type of notification you are using ```Data messages``` or ```Notification messages```? – Afsar edrisy Jan 21 '20 at 09:33

Some devices have restrictions to start automatically. So if notification comes, your app will not receive the notification.

You have to enable Autostart for your app to work. There is a setting called "Autostart". Turn on that for your app.

    Hi, welcome to SO! That will not work since the app's FMC service still needs to run. Next time when you answer a question please add a bit more context, you may be right with your answer, add some instructions/steps to show how to do it. – Nathan Jan 21 '20 at 09:47
  • Hi Nathan, if you need to understand about autostart in different devices. Please go through below link, https://stackoverflow.com/questions/44383983/how-to-programmatically-enable-auto-start-and-floating-window-permissions – Karthik Jan 21 '20 at 09:50
  • Sorry, no I do understand it, I'm saying you should add more information in your answers, I'm not the one asking the question. Autostart will not work with firebase, you'll need to use a FMC endpoint when the app is closed to receive notifications. – Nathan Jan 21 '20 at 09:52
  • There is nothing called FMC endpoint. Although some sources say that this is an issue of Firebase and more about the manufacturer who does not use Android's native ROM. Manufactures like One Plus, MI, Vivo, Oppo, etc use customised ROM (rewrite the behaviour of stock Android). So when the app is killed, all its services are also killed. So to solve this you can change their settings. – Karthik Jan 22 '20 at 03:05
