title: Cancel Notification which has been set using AlarmManager and BroadCast Reciever
body: <p>In my Activity I set time for AlarmManager to generate a notification on future date and also stores the information in sqlite db. After setting multiple notification by changing ids to notify for notificationManager I show information in ListView. </p>
  
  <p>Now I want cancel the or delete some notifications. For example I set time for notification for after 1 hour and I want to cancel it on longitemclick of listview but notification generates . </p>
  
  <p>I saw the way how to cancel notification from notification bar but that not suitable for my case. I want to cancel notification before it is going to generate.</p>
  
  <p>How can i achieve this?</p>
  
  <p><strong>here is my code for calling notification:</strong></p>
  
  <pre><code>custom = new CustomDateTimePicker(noticall.this,new CustomDateTimePicker.ICustomDateTimeListener() {
  
                 @Override
                 public void onCancel() { 
                     finish();
                 }
  
  
                 @Override
                 public void onSet(Dialog dialog, Calendar calendarSelected,Date dateSelected, int year, String monthFullName,
                              String monthShortName, int monthNumber, int date,
                              String weekDayFullName, String weekDayShortName,
                              int hour24, int hour12, int min, int sec,
                              String AM_PM) {
  
                        Calendar calendar =  Calendar.getInstance();
                        calendar.set(year, monthNumber, date, hour24,  min, 0);
  
                        long when = calendar.getTimeInMillis();         // notification time
  
  
                        myIntent = new Intent(noticall.this, MyReceiver.class);
                        pendingIntent = PendingIntent.getBroadcast(noticall.this, 0, myIntent,0);
  
                        alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
                        alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
  
  
          Date = calendarSelected.get(Calendar.DAY_OF_MONTH) + "/" + (monthNumber+1) + "/" +year; 
          Time = hour12 + ":" + min + " " + AM_PM;
  
  
          setlisto(Date);
          Intent intent = getIntent();
          finish();
          startActivity(intent);    
  
          Toast.makeText(noticall.this,"Record Added", Toast.LENGTH_SHORT).show();
  
             }
