pending intent / alarm not working second time

My code is like this, on button click i execute
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis()+(1000*5));
Intent intent = new Intent(LogoFrontScreen.this,Doubletest.class);
PendingIntent alarmIntent = PendingIntent.getBroadcast(LogoFrontScreen.this,2,intent,PendingIntent.FLAG_UPDATE_CURRENT);
alarmMgr.setExact(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), alarmIntent);
PendingIntent alarmIntent1 = PendingIntent.getBroadcast(LogoFrontScreen.this,2,intent,PendingIntent.FLAG_UPDATE_CURRENT);
alarmMgr.setExact(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis()+(2000), alarmIntent1);
then on receiver there is a log but that log is called only once, why this is happening ?

In stead of
alarmMgr.setExact
Try
alarmMgr.setInexactRepeating
And for scheduling multiple alarm you need to use unique id every time creating
PendingIntent alarmIntent = PendingIntent.getBroadcast(LogoFrontScreen.this,2,intent,PendingIntent.FLAG_UPDATE_CURRENT);
The second argument of getBroadcast(i.e. 2 in your case) need to be different for every alarm.
Hope it will solve your problem :)

How can i set the alarm on the particular date in android?

Explanation:
I have calendar in which i set the events on the particular day of the given month.The event is stored into the database. on the event day is occurs it is trigger an alarm to notice the user.
suppose, my event is save on the 29/05/2016 then my alarm is triggered on the particular date.
Notice:i have multiple event created on the particular month.e.g. on the 29th may or 30th may also.
MyQuestion is how can i fire the multiple alarm on the particular multiple days.
Please, understand the flow what i exactly want?

If you want to play alarm for particular date and time , following code may help you
Calendar cal=Calendar.getInstance();
cal.set(Calendar.MONTH,5);
cal.set(Calendar.YEAR,2012);
cal.set(Calendar.DAY_OF_MONTH,11);
cal.set(Calendar.HOUR_OF_DAY,16);
cal.set(Calendar.MINUTE,10);
cal.set(Calendar.SECOND,0);
Intent _myIntent = new Intent(getApplicationContext(), ReceiverClass.class);
PendingIntent _myPendingIntent =
PendingIntent.getBroadcast(getApplicationContext(), 123, _myIntent,
PendingIntent.FLAG_UPDATE_CURRENT| Intent.FILL_IN_DATA);
AlarmManager myAlarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
//myAlarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (10 * 1000), _myPendingIntent);
myAlarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), _myPendingIntent);

calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR,date.getYear());
calendar.set(Calendar.MONTH,date.getMonth()+1);
calendar.set(Calendar.DAY_OF_MONTH,date.getDate());
calendar.set(Calendar.HOUR_OF_DAY,time.getHours());
calendar.set(Calendar.MINUTE,time.getMinutes());
calendar.set(Calendar.SECOND,time.getSeconds());
Intent myIntent = new Intent(context, AlarmReciever.class);
myIntent.putExtra("ReminderDetails",reminderDetails);
myIntent.putExtra("requestCode", requestCode);
pendingIntent = PendingIntent.getBroadcast(context, (int) (requestCode), myIntent,0);
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, date.getTime(),
interval, pendingIntent);
The following code here is good live for setting a calender time at the specified time and date.
And the most important thing here stands is that what do you pass in 2nd argument in alarmManager.setInexactRepeating(_) method,which is
date.getTime(), which is the only thing will work instead of using
calendar.getTimeinMillis() method, because that will return some unexpected time to be launched for intents.

AlarmManager intent=null

Here's the code I'm using to try and set up an AlarmManager:
feedingIntent = new Intent(this, FeedingAlarmReceiver.class);
feedingPI = PendingIntent.getBroadcast(this, 0, feedingIntent, 0);
feedingAM = (AlarmManager) getSystemService(ALARM_SERVICE);
feedingAM.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() + 60000, feedingPI);
I basically want the feedingIntent to trigger after a minute after a button press. When I check logcat after I press the button it says my intent is null:
V/AlarmManager﹕ sending alarm PendingIntent{435f7ac8: PendingIntentRecord{435b8ed0 com.example.parentingreminders broadcastIntent}}, intent=null, type=ELAPSED_REALTIME_WAKEUP, count=1, when=959128249, repeateInterval=0
This is my first time using AlarmManager and I'm not sure what I'm doing wrong.
Thanks in advance!

You need to set the corresponding action in feedingIntent to trigger the receiver
feedingIntent.setAction(Intent.ACTION_XXXX);

cancel a particular alarm

I am setting alarms at diffrent time . I want to delete a particulat alarm.
Ex. I set 100 alarms at diiferents times , now I want to Delete an alarm set at 25 Feb 2012 10.45 AM. How Can I do that.
I written following code to set alarm.
final AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
GregorianCalendar gc=new GregorianCalendar();
gc.set(2012, 1, 22, 10, 42,0);
Intent intent = new Intent(this, AlarmService.class);
gc.set(Calendar.AM_PM,0);
final PendingIntent sender = PendingIntent.getBroadcast(this, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT);
am.set(AlarmManager.RTC_WAKEUP, gc.getTimeInMillis(), sender);
I have a broadcast receiver to recieve the alarm.

You need to save the request code of alarm,that is 1 in your case here. The 2nd parameter you pass in your PendingIntent.getBroadcast() method is your request code for a particular alarm.So when you save request code along with the time for what you set alarm,it would be easy for you to get the particular alarm instance and then you can cancel it using:
AlarmManager am = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, OneShotAlarm.class); //OneShotAlarm is the broadcast receiver you use for alarm
PendingIntent sender = PendingIntent.getBroadcast(context,alarm_request_code, intent, 0);
am.cancel(sender);
You should take care that each of your request code for different alarms should be unique,otherwise your alarm will be rescheduled with new time you set with the older request code.
Hope you get the point.

You might need to store it in some form of data structure to keep track of the time and the object. That being said, I have not tried storing AlarmManager objects before.

How to set phone's alarm from program code in Android

I want to set phones alarm in phone.
Can anybody say how to do that?
I got the code from net, and try but the alram not set to phone.
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
Intent activate = new Intent(this, Alaram.class);
AlarmManager alarams ;
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, 0, activate, 0);
alarams = (AlarmManager) getSystemService(ALARM_SERVICE);
alarams.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), alarmIntent);
In this code we are provide intent as Alaram.class.
Then what should be written in this Alram.class so that alarm will set to the mobile.

I think you misunderstood what the AlarmManager is good for. It starts your code on a given Point, it doesn't set the phones ring tone.
If you want to set the Phones Alarm sound, this might be helpful (from the standard Android Music Player):
// Set the system setting to make this the current ringtone
MusicUtils.setRingtone(this, mService.getAudioId());

You are setting alarm time as current time in millisecond it will be exceed when the alarmmanager wake up....So,here i modified your code.check this it will work.That alaram will start after 5 seconds...i mean your Alaram activity will start within 5 seconds.
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
Intent activate = new Intent(this, Alaram.class);
AlarmManager alarams ;
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, 0, activate, 0);
alarams = (AlarmManager) getSystemService(ALARM_SERVICE);
alarams.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis()+5000, alarmIntent);
