java - Adding Foreground Service to Activity causes exception when calling onDestroy -

i have simple foreground service follows, shows foreground notification:

public class foregroundlocationservice extends service {      private final string tag = this.getclass().getsimplename();      @override     public void oncreate() {         super.oncreate();          bitmap icon = bitmapfactory.decoderesource(getresources(),                 r.drawable.bullhorn_24dp);          notification notification = new notificationcompat.builder(this)                 .setcontenttitle("signed in")                 .setticker("signed name123")                 .setcontenttext("you broadcasting location")                 .setsmallicon(r.drawable.broadcast_notifcation)                 .setlargeicon(bitmap.createscaledbitmap(icon, 128, 128, false))                 .setongoing(true).build();          startforeground(serviceconstants.notification_id.foreground_service, notification);      }      @override     public void ondestroy() {         super.ondestroy();     }      @nullable     @override     public ibinder onbind(intent intent) {         return null;     } } 

i can start in app calling in activity:

intent service = new intent(this, foregroundlocationservice.class);  startservice(service); 

this displays following image, expected:

the issue when go close app via holding phones home button , swiping app closed. activity’s ondestroy() method called, instead of leaving foreground service running , closing app, following error (and foreground service stops):

the lines error occurs follows:

companynavigationactivity.java:533 ‘super.ondestroy();’

@override public void ondestroy() {     getspecificimpofgenericpresenter().closerealm();     super.ondestroy(); } 

genericmvpactivity.java:100 ‘super.ondestroy();’

@override public void ondestroy() {     //unbind butterknife bindings     if(munbinder!=null) {         munbinder.unbind();     }     super.ondestroy(); } 

and goes off android fragment classes. i’m @ loss why foreground service cause issue lifecycle of activity launched in. if comment out call start service, runs normal.

any ideas how service affecting activity in way?

edit 1

i have service listed in manifest as:

<service android:name=".locationservice.foregroundlocationservice"     android:icon="@drawable/bullhorn_24dp"     android:label="assemble sharing"> </service> 

edit 2

presenters closerealm method below, commenting out in activity's ondestroy method gives same error.

public void closerealm() {     this.mrealmdatabase.getinstance().removeallchangelisteners();     this.mrealmdatabase.close(); }
