How does setting repeating alarm affects on calling in the onCreate()

Question

If I call the setinexactrepeating() alarm method in the onCreate , how does it affect the alarm which is being repeated at the specified interval

Here is the code of setting alarm, I am calling this method in the onCreate()

public void setAlarm()
{
    Intent myintent=new Intent(this,AlarmReciever.class);

    Random random = new Random();


    int ran = random.nextInt(total_words.size());


    String tempString=onlySearch(total_words.get(ran), 1);
    myintent.putExtra("word", total_words.get(ran));
    myintent.putExtra("meaning", tempString);
    myintent.putExtra("language", 1);


    alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);


    PendingIntent pendingIntent=PendingIntent.getBroadcast(this,101,myintent,PendingIntent.FLAG_UPDATE_CURRENT);

    //NotificationTime is the sharedPreference file, in which i am storing hours and minute got from timepicker        

    alarmManager.cancel(pendingIntent);
    Calendar calendar=Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.set(Calendar.HOUR_OF_DAY, NotificationTime.getInt("hour", 12));
    calendar.set(Calendar.MINUTE, NotificationTime.getInt("min", 0));
    calendar.set(Calendar.SECOND, 0);


    if(calendar.before(Calendar.getInstance()))
        calendar.add(Calendar.DATE,1);



    alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
            AlarmManager.INTERVAL_DAY
            , pendingIntent);


    System.out.println("ALARM SET STATUS");
}

Alarm is first scheduling at the exact time perfectly but it does not gets repeated.

Actually I wanted to show notification daily at the specified time and I am passing a String with the intent. By default I had set to 12:00 PM but user can change its time. The first notification after setting time (or the first alarm) is working but its repetition is not working.

Please have a look, and if someone knows a better solution to show notification daily at the same specified time it would be appreciated if you tell me.

Thanks in advance

You should handle changing time on device. And it's better to use ` ELAPSED_REALTIME_WAKEUP` and setRepeating. — Petrov Dmitrii, Jun 16 '16 at 09:24

user setRepeating for Repeating Alarm

 AlarmManager manager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
/* Repeating on every interval */
manager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

You check difference here setRepeating https://developer.android.com/reference/android/app/AlarmManager.html#setRepeating(int, long, long, android.app.PendingIntent)) and setExactRepeating https://developer.android.com/reference/android/app/AlarmManager.html#setInexactRepeating(int, long, long, android.app.PendingIntent) – Sanjay Kakadiya Jun 16 '16 at 09:50
Thank you, but one more ques. When does our alarm is destroyed, i mean if i set the alarm on applications first run then, then whats the factor that might disable my alarm.? – Aziz Jun 16 '16 at 11:18
any factor does not disable your alarm still you do not call alarmManager.cancel(); – Sanjay Kakadiya Jun 16 '16 at 12:01
Does the repeating alarm also not be disabled? because when I close my app from the recent app list in my phone, the alarm does not repeated. – Aziz Jun 16 '16 at 12:21
I'm not fetching this issue. Did you add AlarmReciever in Manifest.xml ? – Sanjay Kakadiya Jun 17 '16 at 06:07
