After launch calendar intent, how to "go ahead" with the app? Android -

escenario:

i have done activity allows user set info create entrance in calendar. afeter verify info launch intent open calendar info set.

thats how donde button:

bnext.setonclicklistener(new onclicklistener() {      public void onclick(view v) {          intent intent = new intent(intent.action_insert).setdata(events.content_uri)                 .putextra(calendarcontract.extra_event_begin_time, begintime.gettimeinmillis())                 .putextra(calendarcontract.extra_event_end_time, endtime.gettimeinmillis())                 .putextra(events.title, subject.gettext().tostring())                 .putextra(events.event_location, location.gettext().tostring())                 .putextra(events.availability, events.availability_busy)                 .putextra(intent.extra_email, "elias.ortiz@in2.es");         startactivity(intent);         }      } }); 

that opens calendar. after , confirm entrance, calendar app still open (as normal) when press "back button" go app.

question:

after come calendar, there way recognize entrance has been set, , go ahead activity?

instead of startactivity, use startactivityforresult calendar. override onactivityresult. if calendar activity returns result_canceled means button pressed. call startactivity on activity want display, , finish() on current activity if need to.
