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);

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 :)
I am setting alarm with an interval of 2 hours. It work very perfect but the problem is, at the time of set it trigger the alarm.
It don't have to trigger alarm at time of set rest is all ok.
Intent _myIntent = new Intent(activity, MyReceiverStartPush.class);
_myIntent.putExtra("msg", "Feed");
PendingIntent _myPendingIntent = PendingIntent.getBroadcast(
activity, 0, _myIntent, 0);
AlarmManager _myAlarmManager = (AlarmManager) activity
.getSystemService(Service.ALARM_SERVICE);
_myAlarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis(), (AlarmManager.INTERVAL_HOUR)
* 2, _myPendingIntent);
Instead of using System.currentTimeMillis() (which is the reason) you should use System.currentTimeMillis() + 2H there
I want to be able to register two alarms to the same BroadcastReceiver. However, the first alarm never gets fired. How can I make this work?
Calendar now = Calendar.getInstance();
now.set(Calendar.SECOND, now.get(Calendar.SECOND) + 5);
long trigger1 = now.getTimeInMillis();
now.set(Calendar.SECOND, now.get(Calendar.SECOND) + 10);
long trigger2 = now.getTimeInMillis();
Intent startIntent = new Intent(AlarmStartReceiver.START_ALARM);
startIntent.putExtra(AlarmStartReceiver.EXTRA_ALARM_ID, 4);
PendingIntent startPIntent = PendingIntent.getBroadcast(context, 0, startIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Intent startIntent2 = new Intent(AlarmStartReceiver.START_ALARM);
startIntent2.putExtra(AlarmStartReceiver.EXTRA_ALARM_ID, 5);
PendingIntent startPIntent2 = PendingIntent.getBroadcast(context, 0, startIntent2, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarm = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarm.set(AlarmManager.RTC_WAKEUP, trigger1, startPIntent);
alarm.set(AlarmManager.RTC_WAKEUP, trigger2, startPIntent2);
Only the second one goes off. How can I make them both go off?
EDIT FOR ANSWER: Set the requestCode to something unique. The second param of the PendingIntent.getBroadcast) method

Are you looking for separate notification event for each alarm you are setting? Or it has to be same notification with number of alarm events showing on the status bar icon?
Look at this post on how you can use "setData()" to the intent to create separate alarms.
Alarm Manager - Scheduling multiple Non-repeating events
here i used alarm manager to call service at particular time . I want to call that service at 23:59:00 . How can i call alarm manager at that particular time ? Please help me to solve this issue.
Calendar calendar=Calendar.getInstance();
calendar.add(Calendar.SECOND,what time to set);
Intent intent=new Intent(getApplicationContext(),StartServiceAlaramReceiver.class);
startAlaramServicePendingIntent=PendingIntent.getBroadcast(getApplicationContext(),0, intent,PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager=(AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),startAlaramServicePendingIntent);
U can give time for alarmmanager using following way,
Intent activate = new Intent(this, AlaramActivity.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);
I find using the JodaTime library for anything with respect to date and time.
Intent intent=new Intent(getApplicationContext(),StartServiceAlaramReceiver.class);
startAlaramServicePendingIntent=PendingIntent.getBroadcast(getApplicationContext(),0, intent,PendingIntent.FLAG_UPDATE_CURRENT);
final DateTime todayE = (new DateTime()).minuteOfDay().withMaximumValue().minusMinutes(1);
AlarmManager alarmManager=(AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP,todayE.getMillis(),startAlaramServicePendingIntent);
The bellow link provide the detail description to set the Event that wil fire on the specified time. http://justcallmebrian.com/?p=129
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);
