android - Date string dose not get parse -

i have string in date format want parse in date object. want set time string in calendar object , want set alert @ same time.

for tried parse string date nothing happens. time dose not set.

when did debug check if time get's set in calendar or not, found goes directly @ end of method after parsing.

date date = df.parse(alertdatetest);

i tried parse string format :
simpledateformat df = new simpledateformat("d mmm yyyy");

but gives invalid format exception. format should use parse string?

string format : d mmm yyyy

code:

malertdate 25 apr 2016 alertdatetest 25 apr 2016

 public void updatenotification() {          try {               string alertdatetest = i.getstringextra("taskalertdate");             string alerttimetest = i.getstringextra("taskalerttime");              simpledateformat  df = new simpledateformat("yyyy-mm-dd");              date date = df.parse(alertdatetest);               if (alertdatetest.equals(malertdate)) {                   string formattedstring = date.tostring();                 calendar c = calendar.getinstance();                  c.set(calendar.hour_of_day, mhouroftheday);                 c.set(calendar.minute, mminute);                 c.set(calendar.second, 0);                  myear = new datetime(formattedstring).getyear();                 mmonth = new datetime(formattedstring).getmonthofyear();                 mdayofmonth = new datetime(formattedstring).getdayofmonth();                  c.set(calendar.year, myear);                 c.set(calendar.month, mmonth);                 c.set(calendar.day_of_month, mdayofmonth);                  date = c.gettime();                  log.d("alertdate", string.valueof(date));                 toast.maketext(addtaskactivity.this, string.valueof(date), toast.length_short).show();                  intent = new intent(addtaskactivity.this, notificationreceiver.class);                 pendingintent = pendingintent.getbroadcast(getbasecontext(), _mid, intent, 0);                 alarmmanager = (alarmmanager) getsystemservice(context.alarm_service);                 alarmmanager.set(alarmmanager.rtc_wakeup, date.gettime(), pendingintent);           } catch (parseexception e) {          }     } 

edit:

i have function ondateset of date picker in have string format , string formatted same format:

 @override     public void ondateset(datepickerdialog view, int year, int monthofyear, int dayofmonth) {      //   string date = "you picked following date: "+dayofmonth+"/"+(++monthofyear)+"/"+year;          simpledateformat  df = new simpledateformat("d mmm yyyy");         mcalendar = calendar.getinstance();         mcalendar.set(calendar.year, year);         mcalendar.set(calendar.month, monthofyear);         mcalendar.set(calendar.day_of_month, dayofmonth);          date date = mcalendar.gettime();           if(date_picker_tag == 1)         {             myear = year;             mmonth = monthofyear;             mdayofmonth = dayofmonth;              malertdate  = df.format(date);             alertdate.settext(string.valueof(malertdate));         }        if(date_picker_tag == 3) {              mduedate  = df.format(date);             duedate.settext(string.valueof(mduedate));         }     } 

edit: tried answer umesh saraswat

            string alertdatetest = i.getstringextra("taskalertdate");             string alerttimetest = i.getstringextra("taskalerttime");              simpledateformat simpledateformate = new simpledateformat("dd mmm yyyy");              date  date = simpledateformate.parse(alertdatetest);            //  date date = df.parse(alertdatetest);               if (alertdatetest.equals(malertdate)) {                   string formattedstring = date.tostring();                 calendar c = calendar.getinstance();                  c.set(calendar.hour_of_day, mhouroftheday);                 c.set(calendar.minute, mminute);                 c.set(calendar.second, 0);                  c.settime(date);                    c.set(calendar.year, myear);                 c.set(calendar.month, mmonth);                 c.set(calendar.day_of_month, mdayofmonth);                  date = c.gettime();
