android - How can I call findViewById inside IntentService? -


is there way call findviewbyid inside intentservice? in case, tried using static reference of mainactivity class. didn't work.

mainactivity class calls intentservice:

public static mainactivity ma;     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         ma=this;         startservice(new intent(this,myservice.class).setaction("myintent"));     }

and myservice class is:

protected void onhandleintent(intent intent) {         if(intent.getaction()=="myintent"){             listview lv=(listview)(mainactivity.ma.findviewbyid(r.id.listview));             toast.maketext(getapplicationcontext(), (mainactivity.ma.findviewbyid(r.id.listview)).tostring(), toast.length_long).show();             }      }

this gives nullpointerexception. verified mainactivity.ma ok inside service class. still, cannot call findviewbyid.

how can resolve this?
