Here is what I tried in my code. Multiple alarms not working properly Android
AlarmManager alarmManager = ((AlarmManager) getSystemService(Context.ALARM_SERVICE));
int time1 = Integer.parseInt(e.getText().toString());
time1 = time1 * 1000;
final int id = (int) System.currentTimeMillis();
Intent intentAlarm = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, id, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT);
long r4 = time1 + System.currentTimeMillis();
alarmManager.set(AlarmManager.RTC_WAKEUP, r4, pendingIntent);
Anyone has any idea what is wrong,
some help will be appreciated, thank you:)
How you are assigning time to trigger alarm alarmManager.set(AlarmManager.RTC_WAKEUP,r4, pendingIntent); is wrong.
The time in seconds you get from user is needed to set in Calendar and then assign that time in the alarmManager.set();
Calendar cal = Calendar.getInstance();
cal.set(Calendar.SECOND, time1);
alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);
Your code would be like,
AlarmManager alarmManager;
alarmManager=( (AlarmManager)getSystemService(Context.ALARM_SERVICE));
int time1 = Integer.parseInt(e.getText().toString());
Calendar cal = Calendar.getInstance();
cal.set(Calendar.SECOND, time1);
final int _id = (int) System.currentTimeMillis();
Intent intentAlarm = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent=PendingIntent.getBroadcast(this,_id , intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

I would like to configure alarm manager for a different timezone. I would like the alarm to trigger a notification whenever 10:20 NY time has reached. Is it possible to code like below?
private void configureDailyAlarm(Context context) {
TimeZone USTimeZone = TimeZone.getTimeZone("America/New_York");
Calendar USCalendar = Calendar.getInstance(USTimeZone);
USCalendar.set(Calendar.HOUR_OF_DAY, 10);
USCalendar.set(Calendar.MINUTE, 20);
Intent alarmReceiverIntent = new Intent(context, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmReceiverIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(context.ALARM_SERVICE);
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, USCalendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
}
Use this method:
public int getTimeFromNY() {
TimeZone USTimeZone = TimeZone.getTimeZone("America/New_York");
Calendar USCalendar = Calendar.getInstance(USTimeZone);
USCalendar.set(Calendar.HOUR_OF_DAY, 10);
USCalendar.set(Calendar.MINUTE, 20);
Calendar calendar = Calendar.getInstance();
calendar.setTime(new Date()); // Current date
return USCalendar.getTimeInMillis() - calendar.getTimeInMillis();
}
Then plug that into AlarmManager
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeInMillis() + USCalendar.getTimeFromNY(), AlarmManager.INTERVAL_DAY, pendingIntent);
I am new to android , I want to make alarm that notify me dialy at 11am .I have found some code on net,But dont know some part of it. Below is code
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(AndroidAlarmService.this, MyAlarmService.class);
pendingIntent = PendingIntent.getService(AndroidAlarmService.this, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis()); does
calendar.add(Calendar.SECOND, 10);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 5*1000, pendingIntent);
Toast.makeText(AndroidAlarmService.this, "Start Alarm", Toast.LENGTH_LONG).show();
}});
can any one explain me what this two line does
calendar.setTimeInMillis(System.currentTimeMillis()); does
calendar.add(Calendar.SECOND, 10);
And also help me how can i set alarm that will notify me on the same time for example at 11am
Call this function where you need:
private void setDailyNotification(int ID, int hh, int mm, int ss) {
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent alarmIntent = new Intent(Dashboard.this, MyDailyReceiver.class);
alarmIntent.putExtra("ID", ID);
Log.d("setDailyNotification", "ID:" + ID);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
Dashboard.this, ID, alarmIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
mEverydayPendingIntent = pendingIntent;
Calendar calendar = Calendar.getInstance();
Calendar now = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, hh);
calendar.set(Calendar.MINUTE, mm);
calendar.set(Calendar.SECOND, ss);
// check whether the time is earlier than current time. If so, set it to
// tomorrow. Otherwise, all alarms for earlier time will fire
if (calendar.before(now)) {
calendar.add(Calendar.DATE, 1);
}
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY,
mEverydayPendingIntent);
Log.d("setRepeated", "ID:" + ID);
}
Broadcast receiver:
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
context);
mBuilder.setContentTitle("Daily Summery");
mBuilder.setContentText("Today's Transaction");
mBuilder.setSmallIcon(R.drawable.app_icon);
Log.d("tag1234", "In if" + daily_Reminder);
NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
mBuilder.setStyle(inboxStyle);
mNotificationMa = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationMa.notify(11, mBuilder.build());
call function like this:
setDailyNotification(11, 11,00, 00);
System.currentTimeMillis()- gets the current time from the device.
calendar.setTimeInMillis()- sets the current time.
calendar.add(Calendar.SECOND, 10) - adds ten seconds to the current time.
In total, you are fetching the current time of the device and adding ten seconds in it.
You can try this Worked for me
int interval = 1000 * 60 * 1;
// 1 for minutes ,you can pass 60*24
//And set alarm manager like this
Intent alarmIntent = new Intent(AlaramManagerActivity.this, NotificationReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(AlaramManagerActivity.this, RQS_1, alarmIntent, 0);
AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
manager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),interval, pendingIntent);
Intent myIntent = new Intent(activity.this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(Splash.this, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Calendar firingCal= Calendar.getInstance();
Calendar currentCal = Calendar.getInstance();
firingCal.set(Calendar.HOUR,11); // At the hour you wanna fire
firingCal.set(Calendar.MINUTE, 0); // Particular minute
firingCal.set(Calendar.SECOND, 0); // particular second
long intendedTime = firingCal.getTimeInMillis();
long currentTime = currentCal.getTimeInMillis();
if(intendedTime >= currentTime){
// you can add buffer time too here to ignore some small differences in milliseconds
// set from today
alarmManager.setRepeating(AlarmManager.RTC, intendedTime, AlarmManager.INTERVAL_DAY, pendingIntent);
}
else{
// set from next day
// you might consider using calendar.add() for adding one day to the current day
firingCal.add(Calendar.DAY_OF_MONTH, 1);
intendedTime = firingCal.getTimeInMillis();
alarmManager.setRepeating(AlarmManager.RTC, intendedTime, AlarmManager.INTERVAL_DAY, pendingIntent);}
Strangely, my Alarm Manger is calling the pending intent immediately, even though I have put a condition if the current time is greater than alarm time run one day later.
I have alarm Manger to trigger everyday at 10PM.
Intent startServiceIntent = new Intent(this, numbers.class);
this.startService(startServiceIntent);
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, Integer.parseInt(res.getString(R.string.hoursvalue))); //10
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.AM_PM, Calendar.PM);
cal.set(Calendar.MILLISECOND, 0);
long alarmtime = cal.getTimeInMillis();
Log.e("ALarm","Time"+alarmtime);
if (currenttime > alarmtime)
{
alarmtime = alarmtime + AlarmManager.INTERVAL_DAY;
Log.e("Current Time","Greater"+alarmtime);
}
if (currentapiVersion >= 19)
{
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent2 = new Intent(this, ServiceForLoadingOnlineNumbers.class);
PendingIntent pi = PendingIntent.getService(this, 741258963, intent2, 0);
am.setInexactRepeating(AlarmManager.RTC_WAKEUP, alarmtime, AlarmManager.INTERVAL_DAY, pi);
}
else if (currentapiVersion >= 16 && currentapiVersion < 19)
{
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent3 = new Intent(this, ServiceForLoadingOnlineNumbers.class);
PendingIntent pi = PendingIntent.getService(this, 741258963, intent3, 0);
am.setRepeating(AlarmManager.RTC_WAKEUP, alarmtime, AlarmManager.INTERVAL_DAY, pi);
}
The Log shows the next day in milliseconds correctly but triggers immediately. What could be the issue here?
Try to use this way and let me know if you face any issues
Date dat = new Date();// initializes to now
Calendar cal_alarm = Calendar.getInstance();
Calendar cal_now = Calendar.getInstance();
cal_now.setTime(dat);
Toast.makeText(mContext, "" + cal_now.getTime(), Toast.LENGTH_LONG)
.show();
;
cal_alarm.setTime(dat);
cal_alarm.set(Calendar.HOUR_OF_DAY, 13);// set the alarm time
cal_alarm.set(Calendar.MINUTE, 10);
cal_alarm.set(Calendar.SECOND, 10);
if (cal_alarm.before(cal_now)) {// if its in the past increment
cal_alarm.add(Calendar.DATE, 1);
}
I suggest checking if the alarm manager is null then canceling the alarm before setting the alarm this took me some time example
if(alarmManger != null){
alarmManger.cancel(operation);
alarmManger.setRepeating(alarmType,alarmtime,AlarmManager.INTERVAL_DAY, operation);
}
I am trying to do something really simple! I have a sessionTimeout variable which have the value 3600000 milliseconds which means 60 minutes/1 hour. I need to set the alarm after 60 minutes. I am using the following code but calendar.getTimeInMillis gives me a very high value. If I just pass 3600000 in the alarmManager it still does not work and trigger the alarm receiver instantly.
private void setupSessionTimeoutAlarm()
{
Calendar calendar = Calendar.getInstance();
calendar.add(calendar.MILLISECOND,(int) sessionTimeout);
long timeInMilliSeconds = calendar.getTimeInMillis() + sessionTimeout;
// schedule the alarm
Intent myIntent = new Intent(Gateway.this, AlarmReceiver.class);
pendingIntent = PendingIntent.getBroadcast(Gateway.this, 0, myIntent,0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP,timeInMilliSeconds,pendingIntent);
}
Calendar calendar = Calendar.getInstance();
Date date = new Date();
date.setTime(System.currentTimeMillis() + (60 * 60 * 1000));
calendar.setTime(date);
Log.i(TAG, "start: " + calendar.getTime().getMinutes());
Log.i(TAG, "start: " + calendar.getTime().getHours());
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, A3LocationUpdateReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, Configuration.LocationUpdateEveryHoursRequest, intent, 0);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_HOUR,
pendingIntent);
I have searched a lot of places but couldnt find a clean sequential explanation of how to start a service (or if thats not possible then an activity) at a specific time daily using the AlarmManager??
I want to register several such alarms and triggering them should result in a service to be started. I'll be having a small piece of code in the service which can then execute and i can finish the service for good....
Calendar cal = Calendar.getInstance();
Calendar cur_cal = Calendar.getInstance();
cur_cal.setTimeInMillis(System.currentTimeMillis());
Date date = new Date(cur_cal.get(Calendar.YEAR), cur_cal.get(Calendar.MONTH), cur_cal.get(Calendar.DATE), 16, 45);
cal.setTime(date);
Intent intent = new Intent(ProfileList.this, ActivateOnTime.class);
intent.putExtra("profile_id", 2);
PendingIntent pintent = PendingIntent.getService(ProfileList.this, 0, intent, 0);
AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarm.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pintent);
System.out.println("The alarm set!!");
i tried this code to activate the alarm at 4.45... but its not firing the service... do i have to keep the process running??
M i doing anything wrong???
One more thing, my service gets perfectly executed in case i use the following code:
long firstTime = SystemClock.elapsedRealtime();
alarm.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, firstTime, 30*1000,pintent);
HI friends,
After a lot of researching and with reference from "Pentium10"'s question on the same topic i managed to get it working. Though i still cant understand why the "date" concept and the Calendar(non GregorianCalendar) object which i have mentioned in the question are not working correctly.
Calendar cur_cal = new GregorianCalendar();
cur_cal.setTimeInMillis(System.currentTimeMillis());//set the current time and date for this calendar
Calendar cal = new GregorianCalendar();
cal.add(Calendar.DAY_OF_YEAR, cur_cal.get(Calendar.DAY_OF_YEAR));
cal.set(Calendar.HOUR_OF_DAY, 18);
cal.set(Calendar.MINUTE, 32);
cal.set(Calendar.SECOND, cur_cal.get(Calendar.SECOND));
cal.set(Calendar.MILLISECOND, cur_cal.get(Calendar.MILLISECOND));
cal.set(Calendar.DATE, cur_cal.get(Calendar.DATE));
cal.set(Calendar.MONTH, cur_cal.get(Calendar.MONTH));
Intent intent = new Intent(ProfileList.this, IntentBroadcastedReceiver.class);
PendingIntent pintent = PendingIntent.getService(ProfileList.this, 0, intent, 0);
AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 30*1000, pintent);
//Create alarm manager
AlarmManager alarmMgr0 = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
//Create pending intent & register it to your alarm notifier class
Intent intent0 = new Intent(this, AlarmReciever.class);
PendingIntent pendingIntent0 = PendingIntent.getBroadcast(this, 0, intent0, 0);
//set timer you want alarm to work (here I have set it to 7.20pm)
Intent intent0 = new Intent(this, OldEntryRemover.class);
Calendar timeOff9 = Calendar.getInstance();
timeOff9.set(Calendar.HOUR_OF_DAY, 19);
timeOff9.set(Calendar.MINUTE, 20);
timeOff9.set(Calendar.SECOND, 0);
//set that timer as a RTC Wakeup to alarm manager object
alarmMgr0.set(AlarmManager.RTC_WAKEUP, timeOff0.getTimeInMillis(), pendingIntent0);
Then in your AlarmReciever class which is a broadcastReciever, under onRecieve method put your logic. This will take care of what ever the logic you want to handle when the time comes to 7.20 pm.
If you need to set multiple alarms, create another Calendar instance & set time values appropriately. You also need to create another instance for pendingIntent otherwise timers will overlap. Then set it to same alarmManager with new timer & pendingIntent.
You can read document from https://developer.android.com/training/scheduling/alarms.html
private AlarmManager alarmMgr;
private PendingIntent alarmIntent;
alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmReceiver.class);
alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
// Set the alarm to start at 8:30 a.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 8);
calendar.set(Calendar.MINUTE, 30);
// setRepeating() lets you specify a precise custom interval--in this case,
// 20 minutes.
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
1000 * 60 * 20, alarmIntent);
The following code should work fine and it starts the service # 7:40 PM every day. Also, if device shuts down then all your alarms get cancelled.
Make sure to set up all the alarms after BOOT is completed.
Intent slIntent = new Intent(this, x.class);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 19);
calendar.set(Calendar.MINUTE, 40);
calendar.set(Calendar.SECOND, 0);
PendingIntent slPendingIntent = PendingIntent.getService(this, 1, slIntent, PendingIntent.FLAG_ONE_SHOT);
AlarmManager alarmManager=(AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, slPendingIntent);
I tried a lot To Start Service on Time So I Have one solution like
Calculate the difference between current time and selected time
from date picker "Return Long timeMileSec = Milliseconds" Difference
after this create a handler inside it and Sleep if "Milliseconds" seconds
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
CreateService();
getActivity().startService(intentServiceObj);
}
}, timeMileSec);
// Below is the service Methods.
private void CreateService() {
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
cal.add(Calendar.DAY_OF_YEAR, year);
cal.set(Calendar.HOUR_OF_DAY, hourScreen);
cal.set(Calendar.MINUTE, minuteScreen);
// cal.setTimeInMillis(timeselectedmillisecond);
Intent intent = new Intent(getActivity(),
ServiceDailyLocationUpdate.class);
pintent = PendingIntent.getService(getActivity(), 0, intent, 0);
alarm = (AlarmManager) getActivity().getSystemService(
Context.ALARM_SERVICE);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.HOUR, 86000 * 1000,
pintent);
}
// Return Differnce between two date
private long calculateDateDiffSecond(String firstDate, String secondDate) {
long numberOfDays = 0;
String dateStart = firstDate;
String dateStop = secondDate;
Date d1 = null;
Date d2 = null;
try {
d1 = sdfTime.parse(dateStart);
d2 = sdfTime.parse(dateStop);
// in milliseconds
long diff = d2.getTime() - d1.getTime();
long diffSeconds = diff / 1000 % 60;
long diffMinutes = diff / (60 * 1000) % 60;
long diffHours = diff / (60 * 60 * 1000) % 24;
long diffDays = diff / (24 * 60 * 60 * 1000);
System.out.print(diffDays + " days, ");
System.out.print("Hours::" + diffHours + " hours, ");
System.out.print("HoursMinute::" + diffMinutes + " minutes, ");
System.out.print(diffSeconds + " seconds.");
numberOfDays = diffDays;
numberOfDays = diff;
} catch (Exception e) {
e.printStackTrace();
}
return numberOfDays;
}
codes above didn't work and below code worked for me.
