android - ANR in a IntentService. -

i anr reported our app users. not able reproduce on our phones.

report in google play says following.

executing service com.myapp/.background.myintentservice (no location available) 

following code inside myintentservice.

public class myintentservice extends intentservice {   public myintentservice() {     super(myintentservice.class.getname()); }  @override protected void onhandleintent(intent intent) {     systemclock.sleep(100);      intent intent2 = new intent(this, homeactivity.class);     intent2.setflags(intent.flag_activity_new_task|             intent.flag_activity_no_animation|             intent.flag_activity_no_history);     startactivity(intent2); } } 

above intent service called @ time when open app mine cleanup notification raised app. after 100ms wanted open app back. see no issues end. following anr received users's phone. how can decode info? can point out code path?
