android - My app closes device low memory -

i developing app android 4.0 uses services. app works fine , not crash. however, when start heavy app on galaxy s3 app closes, example. when use candy crash app crashes no reason.

is because device on low memory , app doesn't close correctly? or maybe because use getapplicationcontext() inside service?

my service activated on specific time.

thanks help. can see problem downloading https://play.google.com/store/apps/details?id=com.digicode.keepintouch

this code of service: public void startremindersservice(context context) { intent myintent = new intent(context, myalarmservice.class);

    myintent.putextra(constants.contact_id, "-1");      int id = 2;     pendingintent pendingintent = pendingintent.getservice(context, id,             myintent, pendingintent.flag_update_current);      calendar calendar = calendar.getinstance();     calendar.set(calendar.hour_of_day, 8);     calendar.set(calendar.minute, 55);     calendar.set(calendar.second, 0);     calendar.set(calendar.day_of_year, 1);      alarmmanager alarmmanager = (alarmmanager) context             .getsystemservice(context.alarm_service);     alarmmanager.cancel(pendingintent);      alarmmanager.setrepeating(alarmmanager.rtc_wakeup,             calendar.gettimeinmillis(), alarmmanager.interval_day,             pendingintent);
