I want my service to restart itself after a certain time interval but it doesnt seem to happen.
Can anybody please advice?

I know how to trigger a background service in android even on specific time. I have used AlarmManager to achieve this, but I want to start that service daily on that time.
Suppose I want to start it on 12pm, but the service should keep going on after that. I have also used the stopitself() method, but that does not work.
Here is my code:
void alram(Context ctx){
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
cal.set(Calendar.HOUR_OF_DAY, 12);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.AM_PM,Calendar.AM);
Intent serviceIntent = new Intent(ctx, ServiceClass.class);
PendingIntent servicePendingIntent =
PendingIntent.getService(ctx,Service_Apps.SERVICE_ID,serviceIntent,0);
AlarmManager alarm = (AlarmManager) ctx
.getSystemService(Context.ALARM_SERVICE);
alarm.set(AlarmManager.RTC_WAKEUP,cal.getTimeInMillis(),servicePendingIntent);
alarm.setRepeating(
AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(),
AlarmManager.INTERVAL_DAY,
servicePendingIntent
);
}
Hi Please use this code it will help to fill your desires.
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 12);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
PendingIntent pi = PendingIntent.getService(this, 0,
new Intent(this, Service_Apps.class),PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, pi);
I have an alarmManager that repeats at 9AM every day that calls a service. I would like to trigger the alarm every day (repeating) at 9AM with Service A, Noon with Service B, and 4PM with Service C.
My current method of doing this it to repeat every 3 hours and get the current time in the Service and figure out which action should be triggered based on the time, but this feels overly hacky. Here is my code. I wish I could instantiate multiple AlarmManager instances but I doubt I can given the way it is initialized.
Intent i_notifcreate = new Intent(this, NotifCreator.class);
PendingIntent pi_notifcreator = PendingIntent.getService(this, 0, i_notifcreate, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 9);
calendar.set(Calendar.MINUTE, 00);
Log.e("NextAlarm", calendar.getTime().toString());
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_HOUR, pi_notifcreator);
pseduocode inside Service
if(time == 9AM){
A()
} else if (time == noon){
B()
} ... etc
I was able to figure it out using this poorly titled question alarmmanager 2 times
Calendar cal1 = Calendar.getInstance();
cal1.set(Calendar.HOUR_OF_DAY, 05);
cal1.set(Calendar.MINUTE, 45);
cal1.set(Calendar.SECOND, 00);
Calendar cal2 = Calendar.getInstance();
cal2.set(Calendar.HOUR_OF_DAY, 17);
cal2.set(Calendar.MINUTE, 30);
cal2.set(Calendar.SECOND, 00);
// Test if the times are in the past, if they are add one day
Calendar now = Calendar.getInstance();
if(now.after(cal1))
cal1.add(Calendar.HOUR_OF_DAY, 24);
if(now.after(cal2))
cal2.add(Calendar.HOUR_OF_DAY, 24);
// Create two different PendingIntents, they MUST have different requestCodes
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent morningAlarm = PendingIntent.getBroadcast(getApplicationContext(), 0, intent, 0);
PendingIntent eveningAlarm = PendingIntent.getBroadcast(getApplicationContext(), 1, intent, 0);
// Start both alarms, set to repeat once every day
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, morningAlarm);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal2.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, eveningAlarm);
In my app, I need to start a service at 2:00pm daily. Right now I wrote the code to trigger the alarm once, this code is ran every time I open the app:
AlarmManager alarmMgr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, DownloadReceiver.class);
PendingIntent pIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmMgr.cancel(pIntent);
Calendar cal= Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
cal.set(Calendar.HOUR_OF_DAY,refreshhour);
cal.set(Calendar.MINUTE,refreshmin);
cal.set(Calendar.SECOND, 0);
// if the scheduler date is passed, move scheduler time to tomorrow
if (System.currentTimeMillis() > cal.getTimeInMillis()) {
cal.add(Calendar.DAY_OF_YEAR, 1);
}
if(android.os.Build.VERSION.SDK_INT>=23) {
alarmMgr.setAndAllowWhileIdle(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(), pIntent);
}
else{
alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, pIntent);
}
Q1. I used setAndAllowWhileIdle() for sdk above 23 in case the device is in Doze mode. I cannot find any option in this function that I can set the alarm to repeat every day.
Q2. I also have questions about setInexactRepeating() , normally it is set to repeat every day by setting the parameter INTERVAL_DAY , but in the docs, it says
As of API 19, all repeating alarms will be inexact and subject to
batching with other alarms regardless of their stated repeat interval.
Does this mean INTERVAL_DAY does not work anymore, so how can I set the alarm daily without rerunning this function and reset alarmManager?
Try below code will solve your problem-
AlarmManager alarmMgr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
boolean flag = (PendingIntent.getBroadcast(this, 0,
new Intent("totime.action.string"),
PendingIntent.FLAG_NO_CREATE) != null);
if(!flag)
{
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 14);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
Intent intent = new Intent("totime.action.string");
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) Data_Graph.this.getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),(24*60*60*1000), pendingIntent);
}
The below code triggers alarm randomly at any time, but I want to trigger it only at 8 AM and daily.
What I am missing, please help. Thanks in advance.
Intent alarmIntent = new Intent(context, NotifyingDailyService.class);
PendingIntent alarmPIntent = PendingIntent.getService(context, 0, alarmIntent, 0);
// Set the alarm to start at approximately 8:00 a.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 8);
calendar.set(Calendar.MINUTE, 0);
AlarmManager alarmMgr= (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
alarmMgr.cancel(alarmPIntent);
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, alarmPIntent);
I believe AlarmManager.INTERVAL_DAY is only appropriate for calls to setInexactRepeating(). I think you need to change AlarmManager.INTERVAL_DAY to the number of milliseconds in a day.

ALARM MANAGER EXAMPLE
Android: How to repeat a service with AlarmManager every 15 minutes, but only run from 8:00AM to 18:00PM?
I solved the question myself by using broadcast rather than service.
Intent alarmIntent = new Intent(context, DailyNotificationAlarmReceiver.class);
PendingIntent alarmPIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0);
// Set the alarm to start at approximately 8:00 a.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 8);
calendar.set(Calendar.MINUTE, 0);
//System.out.println("Alarm set at 8 clock");
Toast.makeText(context, "Alarm set at 8 clock", Toast.LENGTH_LONG).show();
AlarmManager alarmMgr= (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
// With setInexactRepeating(), you have to use one of the AlarmManager interval
// constants--in this case, AlarmManager.INTERVAL_DAY.
alarmMgr.cancel(alarmPIntent);
//alarmMgr.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmPIntent);
//alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),calendar.getTimeInMillis()+ DateUtils.DAY_IN_MILLIS, alarmPIntent);
alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY, alarmPIntent);
I am starting a service using AlarmManager which wakes up after 5 minutes and does some tasks, but I can't stop the service. How can I do this?
My code for starting the service:
Intent myIntent = new Intent(MainActivity.this, SendDataService.class);
pendingIntent = PendingIntent.getService(MainActivity.this, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
// Wake up after 5 minutes
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000*60*5, pendingIntent);
