below codes intent:
floatingactionbutton fab; fab = (floatingactionbutton) rootview.findviewbyid(r.id.fabaddconlist); fab.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { intent createcontactlist = new intent(context, createcontactlistactivity.class); createcontactlist.addflags(intent.flag_activity_no_animation); startactivity(createcontactlist); } });
this same error here:
how startactivity using actionbar item
see line in logcat:
com.example.l33902.contactmanagment.createcontactlistactivity.oncreate(createcontactlistactivity.java:45) it states have error in createcontactlistactivity.java on line 45.
