  <pre><code>Calendar ca = Calendar.getInstance();
  ca.setTimeInMillis(System.currentTimeMillis());
  int hr = ca.get(Calendar.HOUR)*60*60*1000;
  int hr1 = ca.get(Calendar.MINUTE)*60*1000;
  int hr2 = ca.get(Calendar.SECOND)*1000;
  
  int cal = hr + hr1;
  
  for(int y=1;y&lt;h.length;y++){
      Toast.makeText(getApplicationContext(), "" +h[y],3000).show();
      String q[]=h[y].split(":");
  
      Integer i=Integer.parseInt(q[0]) * 60 * 60 * 1000;
      Integer i2=Integer.parseInt(q[1]) * 60 * 1000;
  
      long set= i + i2;
      long interval= set - cal;
      Toast.makeText(getApplicationContext(), "" +interval,3000).show();
      intr.add(interval);
  
      y++;
  }
  
  AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
  ArrayList&lt;PendingIntent&gt; intentArray = new ArrayList&lt;PendingIntent&gt;();
  
  for(int i = 0; i &lt; intr.size(); ++i){
      Intent intentAlarm = new Intent(getApplicationContext(),AlarmReciever.class);
      PendingIntent p=PendingIntent.getBroadcast(getApplicationContext(), i, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT);
      alarmManager.set(AlarmManager.RTC_WAKEUP, ca.getTimeInMillis()+intr.get(i), p);
  
      //...
  }
  </code></pre>
