You have to implement a foreground service:

https://developer.android.com/guide/components/services.html#Foreground

A foreground service is a service that’s considered to be something
the user is actively aware of and thus not a candidate for the system
to kill when low on memory. A foreground service must provide a
notification for the status bar, which is placed under the “Ongoing”
heading, which means that the notification cannot be dismissed unless
the service is either stopped or removed from the foreground.

Example:

Notification notification = new Notification(R.drawable.icon, getText(R.string.ticker_text),
        System.currentTimeMillis());
Intent notificationIntent = new Intent(this, ExampleActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.setLatestEventInfo(this, getText(R.string.notification_title),
        getText(R.string.notification_message), pendingIntent);
startForeground(ONGOING_NOTIFICATION_ID, notification);
