应用程序自行终止后，是否重新启动了START_STICKY服务？

Question

So if I understand right, the difference between START_STICKY and START_NOT_STICKY is that the first will be restarted by the system, in case it kills it.

Does anyone know whether this also happens when I kill my application using Process.killProcess(Process.myPid()) ? Or does the system only restart the service if the service was actually being killed externally, not from within the application process?

Answer 1

Not always, you can't depend on START_STICKY for continuing running the service. Better way is to use startForeground for continuing running or if you want to repeat specific task then schedule your service on specific time. Also, manage it when the phone is Restarted as well.

Notification.Builder builder = new Notification.Builder(getBaseContext())
                    .setContentTitle(""); 
                    .setContentText("Your content text");
startForeground(1, builder.build());

Answer 2

Yes, the START_STICKY service is restarted after the application is killed by the Android System.

Until and unless you call stopService() method from an app component or stopSelf() from within the service, the service will be restarted if the app is killed.

But you can always make the service run using startForeground() method, in which you will have to show a notification in the status bar for your service. If you create a service using this method, your service will run at the same priority as an active activity. This means that it is highly unlikely that your service will be stopped, and no restart would be required.
