According to the docs:
A foreground process is one that is required for what the user is currently doing. Various application components can cause its containing process to be considered foreground in different ways. A process is considered to be in the foreground if any of the following conditions hold:
It is running an Activity at the top of the screen that the user is interacting with (its onResume() method has been called).
> It has a BroadcastReceiver that is currently running (its BroadcastReceiver.onReceive() method is executing).
It has a Service that is currently executing code in one of its callbacks (Service.onCreate(), Service.onStart(), or Service.onDestroy()).
I use API 27 and when i run the start service, the process is in the foreground and thus the service should start. But instead i get the error which is the restriction of Android Oreo. Are the docs inaccurate?
@Override
public void onReceive(Context context, Intent intent) {
// assumes WordService is a registered service
context.startService(new Intent(context, HelloService.class));
}
