I have an alarmmanager set to fire every 3 hours a day and its working fine. Now my problem is i dont want alarmmanager to fire at night hours i.e from 9pm to 9am on next day.
My code:
Intent myIntent = new Intent(context, MyScheduledReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MILLISECOND, 0);
long interval = 3*60*60*1000;
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), interval, pendingIntent);
and to stop this alarmmanager repeating, i used this snippet to stop manually.
Intent myIntent = new Intent(context, MyScheduledReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
Now how do i check if the time is in night hours or at day hours?

I am having a issue with alarm manager. I need to remove old alarm set to a particular time and reset the alarm to new time. I have tried many scenarios and none working for me. Any help should be greately appreciated.enter code here
// To remove alarm
am = (AlarmManager) getContext().getSystemService( ALARM_SERVICE);
Intent i = new Intent( getContext(),AlarmReceiver.class);
PendingIntent p = PendingIntent.getBroadcast( getContext(), profileFragmentRequestCode, i, 0);
am.cancel(p);
p.cancel();
// To set new alarm
am = (AlarmManager) getContext().getSystemService(ALARM_SERVICE);
/* Retrieve a PendingIntent that will perform a broadcast */
Intent alarmIntent = new Intent(getContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), profileFragmentRequestCode, alarmIntent, 0);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 14);
calendar.set(Calendar.MINUTE, 55);
if (android.os.Build.VERSION.SDK_INT >= 19) {
am.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
} else {
am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}
Make sure you have used same REQUEST_CODE with your PendingIntent both for setting and canceling alarm.
SET ALARM:
AlarmManager alarmManager = (AlarmManager) getContext().getSystemService(Context.ALARM_SERVICE);
Intent alarmIntent = new Intent(getContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), REQUEST_CODE, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent)
CANCEL ALARM:
AlarmManager alarmManager = (AlarmManager) getContext().getSystemService(Context.ALARM_SERVICE);
Intent alarmIntent = new Intent(getContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), REQUEST_CODE, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.cancel(pendingIntent);
I have built an alarm which works properly:
public static void setAlarm(int hours, int minutes) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, hours);
calendar.set(Calendar.MINUTE, minutes);
Intent myIntent = new Intent(PreferenceHelper.getContext(), TimeManagementAdapter.AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(PreferenceHelper.getContext(), 0, myIntent, 0);
alarmManager.set(AlarmManager.RTC, calendar.getTimeInMillis(), pendingIntent);
}
Now, how can I edit the alarm time and delete the alarm?
For cancelling the alarm you may call AlarmManager.cancel with your PendingIntent.
Intent myIntent = new Intent(PreferenceHelper.getContext(), TimeManagementAdapter.AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(PreferenceHelper.getContext(), 0, myIntent, 0);
alarmManager.cancel(pendingIntent);
For editing the alarm, you have the option to first cancel it and re-add it or you may add PendingIntent.FLAG_UPDATE_CURRENT as the last option when scheduling a new alarm.
PendingIntent pendingIntent = PendingIntent.getBroadcast(PreferenceHelper.getContext(), 0, myIntent, 0, PendingIntent.FLAG_UPDATE_CURRENT);

I have an AlarmService that is initialized when the devicve boots, starts at 6 am, ends at 6 pm and repeats hourly.
How do I make sure that it starts again after I cancel it at 6 pm?
This is my BootReceiver:
if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
// assign RefreshService class
Intent alarmIntent = new Intent(context, RefreshService.class);
PendingIntent alarmPendingIntent = PendingIntent.getBroadcast(context, alarmManagerRequestCode, alarmIntent, 0);
// set the alarm
// it starts at 6 am and repeats once an hour
// elapsed_realtime is used to save ressources
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME, firstRefresh,
AlarmManager.INTERVAL_HOUR,
alarmPendingIntent);
}
So it is initialized when the device boots and starts at 6 am (firstRefresh) and repeats hourly.
To have it stop I would put the following into my RefreshService(lastRefresh is 6 pm in milliseconds):
if (System.currentTimeMillis() >= lastRefresh) {
Intent alarmIntent = new Intent(this, RefreshService.class);
PendingIntent alarmPendingIntent = PendingIntent.getBroadcast(this, BootReceiver.alarmManagerRequestCode, alarmIntent, 0);
AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(alarmPendingIntent);
}
Appreciate y'alls help!
Thanks #Opiatefuchs for pointing that out:
The only thing you have to do is setting the alarm after cancelling it and setting the first time it's fired to needed time the next day.
Use calender, AlarmManager and pendingIntent for this-
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 5); // For 5 AM or 6 AM
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
PendingIntent pi = PendingIntent.getService(context, 0,
new Intent(context, NewClass.class),PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, pi);
Use setRepeating:
here is the nice example:
https://stackoverflow.com/a/13879448/4617458
StartAlarmMethod();
AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context,AlarmManagerBroadcastReceiver.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.DAY_OF_WEEK, day);
calendar.set(Calendar.HOUR_OF_DAY, hours);
calendar.set(Calendar.MINUTE, minutes);
calendar.set(Calendar.SECOND, seconds);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000 , pi);
I am using PendingIntents for multiple Alarms. How can i properly use TAGS, so i can later cancel only the Alarm that i don't want to use anymore?
Right now i'm seting Alarms with the code above. But if i set more than 1, using the code appears bellow i stop all upcoming Alarms. Instead of that i want to be able to identify somehow this PendingIntents and cancel only the ones that are not required.
CancelMethod();
Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class);
PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(sender);
To support multiple alarms send a different request code each time you call it in the getBroadcast method. To cancel just send the same request code.
Below code you can loop it within for.
Note: replace i with any value and when cancelling pass the same value to cancel the particular alarm.
AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent alarmIntent = new Intent(context, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, i, alarmIntent, 0);
manager.set(AlarmManager.RTC_WAKEUP, 10000, pendingIntent);
To cancel, send the requestcode which you want to cancel,
Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class);
PendingIntent sender = PendingIntent.getBroadcast(context, i, intent, 0);
alarmManager.cancel(sender);
I'd like to show a dialog at specific date and time (25/12/2012 at 12.00) and I am using this code. I set like 11 month (because 0 is gen) but the alarm does not start. What is my mistake?
Calendar cal=Calendar.getInstance();
cal.set(Calendar.MONTH,11);
cal.set(Calendar.YEAR,2012);
cal.set(Calendar.DAY_OF_MONTH,25);
cal.set(Calendar.HOUR_OF_DAY,12);
cal.set(Calendar.MINUTE,00);
cal.set(Calendar.SECOND,0);
Intent _myIntent = new Intent(context, Notify.class);
PendingIntent _myPendingIntent = PendingIntent.getBroadcast(context, 123, _myIntent, PendingIntent.FLAG_UPDATE_CURRENT| Intent.FILL_IN_DATA);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), _myPendingIntent);
Look at below code about how i am going to set the alarm for the December month:
// for Alarm 25/12/2012 at 12.00
Calendar myAlarmDate = Calendar.getInstance();
myAlarmDate.setTimeInMillis(System.currentTimeMillis());
myAlarmDate.set(2012, 11, 25, 12, 00, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent _myIntent = new Intent(context, AlarmReceiverNotificationForEveryMonth.class);
_myIntent.putExtra("MyMessage","HERE I AM PASSING THEPERTICULAR MESSAGE WHICH SHOULD BE SHOW ON RECEIVER OF ALARM");
PendingIntent _myPendingIntent = PendingIntent.getBroadcast(context, 123, _myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.RTC_WAKEUP, myAlarmDate.getTimeInMillis(),_myPendingIntent);
You can update the above code with your intent and class and you will get your desire output.
Hope this help you.
