Im a just new in android and im currently working on scheduler app.This is my code on setting alarm using SQLite db values.
My problem here is that the alarm is triggering on random time.
public void startAlarm() throws ParseException {
Date dt = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm a");
String time = sdf.format(dt);
String start_time;
Calendar sCalendar = Calendar.getInstance();
String dayLongName = sCalendar.getDisplayName(Calendar.DAY_OF_WEEK, Calendar.LONG, Locale.getDefault());
DatabaseHelper helper = new DatabaseHelper(getApplicationContext());
SQLiteDatabase sqLiteDatabase = helper.getReadableDatabase();
String checktime = "Select * from SCHEDULE where week_day='"+dayLongName+"'";
Cursor cursor = sqLiteDatabase.rawQuery(checktime, null);
if(cursor.moveToNext()) {
start_time = cursor.getString(cursor.getColumnIndex(DatabaseHelper.STARTTIME));
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("hh:mm a",Locale.getDefault());
SimpleDateFormat simpleDateFormat2 = new SimpleDateFormat("hh:mm",Locale.getDefault());
Date milli =simpleDateFormat2.parse(start_time);
String milli2 = simpleDateFormat2.format(milli);
Date timeparsed1 = simpleDateFormat.parse(start_time);
String timeparsed2 = simpleDateFormat.format(timeparsed1);
String s = milli2;
Pattern p = Pattern.compile("(\\d+):(\\d+)");
Matcher m = p.matcher(s);
if (m.matches()) {
int hrs = Integer.parseInt(m.group(1));
int min = Integer.parseInt(m.group(2));
long ms = (long) hrs * 60 * 60 * 1000 + min * 60 * 1000;
// System.out.println("hrs=" + hrs + " min=" + min + " ms=" + ms);
Intent intent = new Intent(this, MyBroadcastReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 234324243, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, ms , pendingIntent);
//Toast.makeText(getApplicationContext(),String.valueOf(ms),Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(),"Bad Format",Toast.LENGTH_SHORT).show();
}
}
After Android 4.4, Google has introduced OS power management mechanism to minimize power use. Try adding a version checking in your code similar to the one below. If the version is KitKat and above, use setExact(). Otherwise use set().
See example below:
//For Android version 4.4 up, use setExact() for the alarm
//otherwise use set()
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
alarmManager.setExact(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + syncInterval * 1000, pendingIntent);
} else {
alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + syncInterval * 1000, pendingIntent);
}

Try this set of code your service never going to stop it works for me. "setInexactReapeating" not working in many of the lollipop and marshmallows devices once it started then lose control over the service this will help you out.
if (android.os.Build.VERSION.SDK_INT >= 23)
{
piLR = PendingIntent.getBroadcast(context, 0, intentLR,
PendingIntent.FLAG_UPDATE_CURRENT);
amLR.setAndAllowWhileIdle(AlarmManager.ELAPSED_REALTIME_WAKEUP,
interval, piLR);
}
else if (android.os.Build.VERSION.SDK_INT >= 19
&& android.os.Build.VERSION.SDK_INT < 23)
{
piLR = PendingIntent.getBroadcast(context, 0, intentLR,
PendingIntent.FLAG_UPDATE_CURRENT);
amLR.setInexactRepeating(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis(), interval, piLR);
}
else
{
amLR.setRepeating(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis(), interval, piLR);

Hello Below is my code to Start the alarm in my application.
public static void startReferAlarm(Context context,String[] message,String activityToOpen)
{
try {
Log.d("Refer friend Activity", "Alarm On");
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 8);
Intent myIntent = new Intent(context, AlarmReciever.class);
myIntent.putExtra("message",message);
myIntent.putExtra("äctivityName",activityToOpen);
final int _id = (int) System.currentTimeMillis();
PendingIntent appIntent = PendingIntent.getBroadcast(context, _id, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//48*60*60*1000
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
48*60*60*1000, appIntent);
}catch (Exception e) {
Log.d("MyActivity", "Alarm Off");
e.printStackTrace();
}
}
From my understating above code will start the alarm and will notify on 8 am. and then will repeat after 48 hours.
But I want to start the alarm after 48 hours or lets say after 7 hours and then it repeat after every 48 hours.
Please help me with the logic.Thanks in advance.
Do not use calender.set(Calendar.HOUR, 8) as it will set hours to 8'o clock
Try
//if you want to add 7 hours
calender.add(Calender.HOUR, 7); //this will add 7 hours to current time
//if you want to add 7 days
calender.add(Calender.DAY_OF_MONTH, 7); //this will add 7 days to current time
// interval to repeat alarm after 48hours
int interval = 48 * 60 * 60 * 1000;
Replace Calendar.HOUR with Calendar.HOUR_OF_THE_DAY if you want to use it in 24hours format.
See the answer for repeating alarm issue How to repeat alarm in android 6.0
For any one who is still confuse. Below method will initiate the alarm after 7 days of any particular action it will notify on 9 am and will repeat after 48 hours.
public static void startCreateProfileAlarm(Context context,AlarmManager alarmManager ,String[] message,String activityToOpen) {
try {
//working code
Calendar calendar = Calendar.getInstance();
calendar.add(DAY_OF_MONTH,7);
//calendar.add(Calendar.HOUR_OF_DAY,1);
calendar.set(Calendar.HOUR_OF_DAY, 9);
// we can set any time here
//calendar.set(Calendar.HOUR_OF_DAY, 10);
Intent myIntent = new Intent(context, AlarmReciever.class);
myIntent.putExtra("message",message);
myIntent.putExtra("äctivityName",activityToOpen);
final int _id = (int) System.currentTimeMillis();
createProfileAppIntent = PendingIntent.getBroadcast(context, 0, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//48*60*60*1000
//2*60*1000
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
48*60*60*1000, createProfileAppIntent);
}catch (Exception e) {
Log.d("MyActivity", "Alarm Off");
e.printStackTrace();
}
}
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 am trying to invoke a scheduler every Tuesday at 11 AM but somehow below code is not working.
Using Calendar object, I'm getting the next date to be scheduled & then setting it up in scheduler.
Can someone point me what error exists in below code?
private static final int PERIOD = 7 * 24 * 60 * 60 * 1000;
DateFormat formatter = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss", Locale.ENGLISH);
Calendar c = nextDayOfWeek(Calendar.TUESDAY); // Set the day of week at which you want to trigger weekly task
c.set(Calendar.HOUR_OF_DAY, 11); // Set the time at which you want to trigger weekly task
c.set(Calendar.MINUTE, 0);
c.set(Calendar.SECOND,0);
c.set(Calendar.MILLISECOND,0);
boolean weeklyAlarmUp = (PendingIntent.getBroadcast(ctxt, 0, new Intent(ctxt, ScheduledWeeklyService.class), PendingIntent.FLAG_NO_CREATE) != null);
if (!weeklyAlarmUp) {
Intent i = new Intent(ctxt, ScheduledWeeklyService.class);
PendingIntent piWeekly = PendingIntent.getBroadcast(ctxt, 0, i, 0);
AlarmManager alarmMgrWeekly = (AlarmManager)ctxt.getSystemService(Context.ALARM_SERVICE);
alarmMgrWeekly.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), PERIOD, piWeekly);
}
My Utility method is as shown below:
public static Calendar nextDayOfWeek(int dow) {
Calendar date = Calendar.getInstance();
int diff = dow - date.get(Calendar.DAY_OF_WEEK);
if (!(diff > 0)) {
diff += 7;
}
date.add(Calendar.DAY_OF_MONTH, diff);
return date;
}
i m really fed up with the alarm service that i m created. i created an alarm service for showing an alert in my application at 8 am, 4 pm , 12 am of each day in my application. It works fine and alert showing perfectly. i'm canceling my service when closing the app, but some times the alert comes without meeting the time such as after exit the app, when removing the app from tab history, when takes the settings of the device, i'm not getting why this happens, i was checking for a solution in SO but didnt get any proper solution please help me
here giving my code.
public void StartService()
{
Calendar c = Calendar.getInstance();
dfcurrent = new SimpleDateFormat("dd MMM yyyy");
long currentTime = System.currentTimeMillis();
currentdate = new Date(System.currentTimeMillis());
String currentdate1 = dfcurrent.format(currentdate);
Long datetoalert1 = Utility.DateReturn(currentdate1+" - "+08:00AM);
if(datetoalert1 < currentTime)
{
Date d = new Date(datetoalert1);
c.setTime(d);
c.add(Calendar.DATE, 1);
d = c.getTime();
datetoalert1 = d.getTime();
}
Long datetoalert2 = Utility.DateReturn(currentdate1+" - "+04:00PM);
if(datetoalert2 < currentTime)
{
Date d = new Date(datetoalert2);
c.setTime(d);
c.add(Calendar.DATE, 1);
d = c.getTime();
datetoalert2 = d.getTime();
}
Long datetoalert3 = Utility.DateReturn(currentdate1+" - "+00:00AM);
if(datetoalert3 < currentTime)
{
Date d = new Date(datetoalert3);
c.setTime(d);
c.add(Calendar.DATE, 1);
d = c.getTime();
datetoalert3 = d.getTime();
}
Intent myIntent1 = new Intent(Login.this, MyReceiver.class);
pendingIntentSApp1 = PendingIntent.getBroadcast(Login.this, 7, myIntent1,0);
pendingIntentSApp2 = PendingIntent.getBroadcast(Login.this, 8, myIntent1,0);
pendingIntentSApp3 = PendingIntent.getBroadcast(Login.this, 9, myIntent1,0);
AlarmManager alarmManager1 = (AlarmManager)getSystemService(ALARM_SERVICE);
AlarmManager alarmManager2 = (AlarmManager)getSystemService(ALARM_SERVICE);
AlarmManager alarmManager3 = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager1.set(AlarmManager.RTC, datetoalert1, pendingIntentSApp1);
alarmManager2.set(AlarmManager.RTC, datetoalert2, pendingIntentSApp2);
alarmManager3.set(AlarmManager.RTC, datetoalert3, pendingIntentSApp3);
}
i m cancelling this pending intent when closing the app. here giving the code
public void exit_btn_click(View view)
{
Intent myIntent1 = new Intent(Login.this, MyReceiver.class);
pendingIntentSApp1 = PendingIntent.getBroadcast(Login.this, 7, myIntent1,0);
pendingIntentSApp2 = PendingIntent.getBroadcast(Login.this, 8, myIntent1,0);
pendingIntentSApp3 = PendingIntent.getBroadcast(Login.this, 9, myIntent1,0);
AlarmManager alarmManager1 = (AlarmManager)getSystemService(ALARM_SERVICE);
AlarmManager alarmManager2 = (AlarmManager)getSystemService(ALARM_SERVICE);
AlarmManager alarmManager3 = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager1.cancel(pendingIntentSApp1);
alarmManager2.cancel(pendingIntentSApp2);
alarmManager3.cancel(pendingIntentSApp3);
System.exit(0);
}
first of all you should not do this:
AlarmManager alarmManager1 = (AlarmManager)getSystemService(ALARM_SERVICE);
AlarmManager alarmManager2 = (AlarmManager)getSystemService(ALARM_SERVICE);
AlarmManager alarmManager3 = (AlarmManager)getSystemService(ALARM_SERVICE);
enough only one link to alarmManager.
Also try to remove
System.exit(0);
call
try to add flag to the pending intent
pendingIntentSApp1 = PendingIntent.getBroadcast(Login.this, 7, myIntent1,PendingIntent.FLAG_UPDATE_CURRENT);
or better alarm id
You will have to cancel the PendingIntent as well after you cancel the alarm.
try {
alarmManagerstop.cancel(getSendLocationIntent(context, 0));
getSendLocationIntent(context, 0).cancel();
} catch (Exception e) {
e.printStackTrace();
}
This will fix your problem.

codes above didn't work and below code worked for me.
month decreases 1.
and hours 0-11.
int day = ff.getGregorianDay() ;
int month = ff.getGregorianMonth() ;
int year = ff.getGregorianYear();
int hour = TimePicker1.getCurrentHour();
int minute = TimePicker1.getCurrentMinute();
Calendar cal_alarm = Calendar.getInstance();
cal_alarm.setTimeInMillis(System.currentTimeMillis() );
cal_alarm.set(Calendar.YEAR, year);
cal_alarm.set(Calendar.MONTH, month-1);
cal_alarm.set(Calendar.DAY_OF_MONTH, day);
cal_alarm.set(Calendar.AM_PM, Calendar.AM );
cal_alarm.set(Calendar.HOUR, hour);
if( hour >= 12){
cal_alarm.set(Calendar.AM_PM, Calendar.PM );
cal_alarm.set(Calendar.HOUR, hour-12);
}
cal_alarm.set(Calendar.MINUTE, minute );
cal_alarm.set(Calendar.SECOND, 0 );
