Setting up multiple alarms in Android - android

When I make an alarm with the time picker the new one always overrides the previous one. I need help to make multiple alarms that override each other. I am using the following code:
Intent i = new Intent("class");
PendingIntent operation = PendingIntent.getActivity(getBaseContext(), 0, i, Intent.FLAG_ACTIVITY_NEW_TASK);
AlarmManager alarmManager = (AlarmManager) getBaseContext().getSystemService(ALARM_SERVICE);
DatePicker dpDate = (DatePicker) findViewById(R.id.dp_date);
TimePicker tpTime = (TimePicker) findViewById(R.id.tp_time);
int year = dpDate.getYear();
int month = dpDate.getMonth();
int day = dpDate.getDayOfMonth();
int hour = tpTime.getCurrentHour();
int minute = tpTime.getCurrentMinute();
GregorianCalendar calendar = new GregorianCalendar(year, month, day, hour, minute);
long alarm_time = calendar.getTimeInMillis();
alarmManager.set(AlarmManager.RTC_WAKEUP, alarm_time, operation);
Toast.makeText(getBaseContext(), "Alarm is set successfully",Toast.LENGTH_SHORT).show();

Calendar sets alarm for next day

I'm working with Calendar. I use code below to set an alarm. But!!! If I try to set an alarm on Monday(Calendar.Monday) the actual alarm will be set on Tuesday. Why does this happen? I also tried to use Calendar.getInstance(Locale.getDefault()) but it didn't work.
And this is how I set an alarm for Sunday:
setAlarm(Calendar.SUNDAY, h, m, k, y);
My setAlarm() method:
public void setAlarm(int dayOfWeek, int hour, int minute, int position, int y) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.DAY_OF_WEEK, dayOfWeek);
calendar.set(Calendar.HOUR, hour);
calendar.set(Calendar.MINUTE, minute);
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MILLISECOND, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context,MyReceiver_Alarm.class);
Long alarmTime = calendar.getTimeInMillis();
PendingIntent pendingIntent = PendingIntent.getBroadcast(context.getApplicationContext(), position , intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, alarmTime, pendingIntent);
Log.e("Point_1", "Time is " + calendar.getTime());
}
Thank you.

0 Sunday
1 Monday
2 Tuesday
DayOfWeek is 0-based, and it starts from Sunday.
So if you're passing 2, thinking that it's 1-based, you're getting Tuesday instead.

The parameter Calendar.DAY_OF_WEEK starts from SUNDAY, so if u want to set alarm for monday set the value of int dayOfWeek to 2 . refer image link

application start at a specific time using AlarmManager [duplicate]

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);

Use calendar to set alarm notification android

I am trying to get a notification to pop up based on the user date and time they put in. Here is my code for getting the time values
// String GetRawDate Gets The User Value For Date//
String getRawDate = date.getText().toString();
// String SplitDate Splits The Date Into Three Separate Ints//
String[] splitDate = getRawDate.split("/");
// Int GetMonth Gets The Value Of The Month//
int getMonth = Integer.parseInt(splitDate[0]);
// Int GetDay Gets The Value Of The Day//
int getDay = Integer.parseInt(splitDate[1]);
// Int GetYear Gets The Value Of The Year//
int getYear = Integer.parseInt(splitDate[2]);
// Get Military Start Time//
String test = military_start_time;
// Split It//
String[] splitStartTime = test.split(":");
// Get Hour In Integer Form
int getHour = Integer.parseInt(splitStartTime[0]);
// Get Minute In Integer Form//
int getMinute = Integer.parseInt(splitStartTime[1]);
From here I add these values to calendar
// Gets Calendar Instance//
Calendar calendar = Calendar.getInstance();
Calendar cal = Calendar.getInstance();
cal.set(Calendar.MONTH, getMonth);
cal.set(Calendar.YEAR, getYear);
cal.set(Calendar.DAY_OF_MONTH, getDay);
cal.set(Calendar.HOUR_OF_DAY, getHour);
cal.set(Calendar.MINUTE, getMinute);
Then I set my alarm
// Intent To Start Notification After X Seconds//
Intent alertIntent = new Intent(this, ReminderService.class);
alertIntent.putExtra("name", name.getText().toString());
alertIntent.putExtra("time", starttime.getText().toString());
// Defines Alarm Manager//
AlarmManager alarmManager = (AlarmManager)
getSystemService(Context.ALARM_SERVICE);
// Sets Alarm Manager//
alarmManager.set(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), PendingIntent.getBroadcast(this, 1,
alertIntent, PendingIntent.FLAG_UPDATE_CURRENT));
// Starts Activity ListView//
Intent b = new Intent(this, Reminders.class);
startActivity(b);
overridePendingTransition(R.anim.slid_in, R.anim.slid_out);
Say the user has the date of 6/4/15 and the Time 22:10 I want the notification to show up on this time. For some reason it shows up about 5 seconds after the code is run through. Anybody know what I am doing wrong with the alarm?

try using
alarmManager.setExact(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(), PendingIntent.getBroadcast(this, 1,
alertIntent, PendingIntent.FLAG_UPDATE_CURRENT));
P.S: Needs min API:19

AlarmManager firing alarm past the time it was set on the same day, setRepeating

So basically I have this code, time returns 24hour time and repeats the alarm daily.
public setAlarm(String time, Context context){
String[] strTime;
strTime = time.split(":");
int hour, min, sec;
//set when to alarm
hour = Integer.valueOf(strTime[0]);
min = Integer.valueOf(strTime[1]);
sec = 0;
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, hour);
cal.set(Calendar.MINUTE, min);
cal.set(Calendar.SECOND, sec);
//Create a new PendingIntent and add it to the AlarmManager
Intent intent = new Intent(context, AlarmReceiverActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 19248, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) context.getSystemService(Activity.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
}
Anyways, the problem is when I set the alarm 9am while the time is 9:10am, the alarm will go off. Why? I want it not to alarm if it is set past the system time. Ex. set the alarm at 9am while the system time is 9:10am

I got it working now. I added a checker of the alarm time and current time.
public setAlarm(String time, Context context){
String[] strTime;
strTime = time.split(":");
int hour, min, sec;
//set when to alarm
hour = Integer.valueOf(strTime[0]);
min = Integer.valueOf(strTime[1]);
sec = 0;
long _alarm = 0;
Calendar now = Calendar.getInstance();
Calendar alarm = Calendar.getInstance();
alarm.set(Calendar.HOUR_OF_DAY, hour);
alarm.set(Calendar.MINUTE, min);
alarm.set(Calendar.SECOND, sec);
if(alarm.getTimeInMillis() <= now.getTimeInMillis())
_alarm = alarm.getTimeInMillis() + (AlarmManager.INTERVAL_DAY+1);
else
_alarm = alarm.getTimeInMillis();
//Create a new PendingIntent and add it to the AlarmManager
Intent intent = new Intent(context, AlarmReceiverActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 19248, intent, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager am = (AlarmManager) context.getSystemService(Activity.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, _alarm, AlarmManager.INTERVAL_DAY, pendingIntent);
}

The accepted answer is wrong as I tried it and then figured out the solution.
It is wrong because, as you can see here:
Calendar now = Calendar.getInstance();
Calendar alarm = Calendar.getInstance();
alarm.set(Calendar.HOUR_OF_DAY, hour);
alarm.set(Calendar.MINUTE, min);
alarm.set(Calendar.SECOND, sec);
"Calendar now" and "Calendar alarm" will always be the same no matter what because they are doing the same thing almost at the exact same spot in the code so the Calendar.getInstance() wil always be the same.
The solution is this
long _alarm;
Calendar now = Calendar.getInstance();
long oldtimer = now.getTimeInMillis();
cal.set(Calendar.HOUR_OF_DAY, Hours2int);
cal.set(Calendar.MINUTE, minutes2int);
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));
//Calendar alarm = Calendar.getInstance();
long newtimer = cal.getTimeInMillis();
if(newtimer < oldtimer) {
//do the thing
}

Use setInexactRepeating instead of setRepeating
Calendar cal= Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, 9);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
PendingIntent pi = PendingIntent.getService(context, 0,
new Intent(context, MyClass.class),PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, pi);
