Alarm not able to stop

I know this is very simple and can do anyone but i m stuck in this plz help where i did mistake
one think very important i start from one.class and stop in second.class and i can do stop after 3rd or 4th day of start.
i start alarm like this
//set Alarm method
private void SetAutoCleanningService()
{
long when= System.currentTimeMillis() + 1000*20;
long repeattime =Constant.NOTIFICATION_TimeDiff;
if(Constant.IsDebug)
System.out.println("time to trigger is ="+getDate(when, "dd/MM/yyyy hh:mm:ss.SSS"));
Intent intent = new Intent(this, AutoCleaningBroadCast.class);
intent.setAction("systweak.AutoCleanningBroadCast");
PendingIntent pendingIntent = PendingIntent.getBroadcast(ApplicationSetting.this,1234567, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, when, repeattime,pendingIntent);
}
And stop like this
//close Alarm method
private void StopEarlierAlarm() {
// TODO Auto-generated method stub
AlarmManager aManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent intent = new Intent(getBaseContext(), AutoCleaningBroadCast.class);
PendingIntent pIntent = PendingIntent.getBroadcast(ApplicationSetting.this, 1234567, intent,0);
aManager.cancel(pIntent);
}
i use same request code but cant able to stop and on every alarm i show one notification that will be repeat in every alarm calling

You can cancel the alarm like this:
Intent intent = new Intent(this, Mote.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 1352, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
Also, you should remove Intent.FILL_IN_DATA from your call to getBroadcast() in the code where you set the alarm.

Cancel your PendingIntent too.
pIntent.cancel();
Make sure context used in creating intent is same.
If not possible to use same Context, then create intent as a global Static variable and use later.

Check this, it may help you
Step 1:initialize the alarm manager.
AlarmManager alarmManager1;
Step 2:
// for Notification Process
Intent myIntent1 = new Intent(Settings.this,MyNotificationService.class);
pendingintent2 = PendingIntent.getService(SettingsPage.this, 2, myIntent1, 2);
alarmManager1 = (AlarmManager) getSystemService(ALARM_SERVICE);
Calendar calendar1Notify = Calendar.getInstance();
calendar1Notify.setTimeInMillis(System.currentTimeMillis());
calendar1Notify.set(Calendar.HOUR_OF_DAY, 8);
calendar1Notify.set(Calendar.MINUTE, 15);
alarmManager1.set(AlarmManager.RTC_WAKEUP,calendar1Notify.getTimeInMillis(), pendingintent2);
long time24h = 24 * 60 * 60 * 1000;
alarmManager1.setInexactRepeating(AlarmManager.RTC_WAKEUP,calendar1Notify.getTimeInMillis(), time24h,pendingintent2);
Step 3-Stop alarm manager:
alarmManager1.cancel(pendingintent2);

Android alarm manager with fixed date and repetitive

How to create a AlarmManger which can be invoke on fixed date and time, This can be also repeat continuous by nature

unfortunately any of the options on the AlarmManager for repeating tasks doesn't allow such a fine control. Your best approach is to on every alarm, you re-schedule it for the next month.
PendingIntent pendingIntent = // set here your action
Calendar calendar = // set this guy to be the next 5th day
AlarmManager am = // get reference to the manager
am.set(RTC, calendar.getTimeInMillis(), pendingIntent);
on inside this Pending intent action you repeat the code. For example, let's say you want to launch a BroadcastReceiver
onReceive(Context context, Intent intent){
Calendar calendar = // set this guy to be the next 5th day
AlarmManager am = // get reference to the manager
am.set(RTC, calendar.getTimeInMillis(), pendingIntent);
}
to set the calendar object is easy:
Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.MONTH, 1);
calendar.set(Calendar.DAY, 5);

I just read a good answer to do the same.
The code is-
Calendar cal=Calendar.getInstance();
cal.set(Calendar.MONTH,5);
cal.set(Calendar.YEAR,2012);
cal.set(Calendar.DAY_OF_MONTH,11);
cal.set(Calendar.HOUR_OF_DAY,16);
cal.set(Calendar.MINUTE,10);
cal.set(Calendar.SECOND,0);
Intent _myIntent = new Intent(getApplicationContext(), ReceiverClass.class);
PendingIntent _myPendingIntent = PendingIntent.
getBroadcast(getApplicationContext(), 123,
_myIntent, PendingIntent.FLAG_UPDATE_CURRENT| Intent.FILL_IN_DATA);
AlarmManager _myAlarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
//_myAlarmManager.set(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis() + (10 * 1000), _myPendingIntent);
_myAlarmManager.set(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(), _myPendingIntent);
This is explained in android-alarm-setting-with-specific-date.

How can I test timed Notification? Or is my code somehow wrong?

I want to deliver timed notifications (everyday, 5:00AM), and tried to do this using AlarmManager with the following code:
Intent appIntent = new Intent(this, NotificationService.class);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
PendingIntent penIntent = PendingIntent.getService(this, 0,
appIntent, 0);
alarmManager.cancel(penIntent);
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, 5);
cal.set(Calendar.MINUTE, 00);
cal.set(Calendar.SECOND, 00);
alarmManager.setRepeating(AlarmManager.RTC, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, penIntent);
The NotificationService.class looks (at least the important parts) like this:
int id = 001;
NotificationManager mNotifyMng = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
MainActivity.this).setSmallIcon(R.drawable.icon).setContentTitle("Test")
.setContentText("Test!");
mNotifyMng.notify(id, mBuilder.build());
stopSelf();
I can't seem to get it to work. When I set the emulator clock to 4:59 or something and wait for it to change to 5:00, there is no notification showing up and I can't figure another way to test it.
I hope you know some way to test it or find the bug in my code.

I believe the problem is that you cancel the PendingIntent but then you need to recreate it again before setting alarmManager.
//cancel pendingIntent
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
PendingIntent penIntent = PendingIntent.getService(this, 0,appIntent, 0);
alarmManager.cancel(penIntent);
//reset pendingIntent
Intent appIntent = new Intent(this, NotificationService.class);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
PendingIntent penIntent = PendingIntent.getService(this, 0,appIntent, 0);
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, 5);
cal.set(Calendar.MINUTE, 00);
cal.set(Calendar.SECOND, 00);
alarmManager.setRepeating(AlarmManager.RTC, cal.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, penIntent);
To cancel a PendingIntent you need to create it exactly as you did the first time then call AlarmManagers cancel() on it as you are. But then you need to create it again to set the alarm on the PendingIntent
**I hope you know some way to test...
There may be a better way but, for testing purposes, I will sometimes set a global debug flag which will change times between testing and production. So say 4 hours might be 2 minutes. Times of the day may be a little more tricky but you can change the time to whatever hour, minute, or whatever is close. Once you know it is triggering at the right time then you can change it back and still test when that time of day comes around but you now know it should be working.

Cancelling alarm from other class that the one which initiated it

I set alarm from one class using this code
Intent myIntent = new Intent(ClassOne.this, AlarmService.class);
pendingIntent = PendingIntent.getService(ClassOne.this, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(currentDate.getTime());
long when = calendar.getTimeInMillis();
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, when, (7 * 24 * 60 * 60) * 1000, pendingIntent);
Now I need to cancel the pending alarms from another class. Can I just use this code?
Intent myIntent = new Intent(ClassTwo.this, AlarmService.class);
PendingIntent pendingIntent = PendingIntent.getService(ClassTwo.this, 0, myIntent, 0);
AlarmManager alarmManagerCancel = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManagerCancel.cancel(pendingIntent);
Or there is a better/proper way to cancel pending alarms?

As long as the PendingIntent are equivalent as the one you used to register the alarm, it doesn't matter where you call cancel() from. Two PendingIntents are equivalent (equals() returns true) if the underlying intents and request codes are the equivalent.

How to set phone's alarm from program code in Android

I want to set phones alarm in phone.
Can anybody say how to do that?
I got the code from net, and try but the alram not set to phone.
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
Intent activate = new Intent(this, Alaram.class);
AlarmManager alarams ;
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, 0, activate, 0);
alarams = (AlarmManager) getSystemService(ALARM_SERVICE);
alarams.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), alarmIntent);
In this code we are provide intent as Alaram.class.
Then what should be written in this Alram.class so that alarm will set to the mobile.

I think you misunderstood what the AlarmManager is good for. It starts your code on a given Point, it doesn't set the phones ring tone.
If you want to set the Phones Alarm sound, this might be helpful (from the standard Android Music Player):
// Set the system setting to make this the current ringtone
MusicUtils.setRingtone(this, mService.getAudioId());

You are setting alarm time as current time in millisecond it will be exceed when the alarmmanager wake up....So,here i modified your code.check this it will work.That alaram will start after 5 seconds...i mean your Alaram activity will start within 5 seconds.
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
Intent activate = new Intent(this, Alaram.class);
AlarmManager alarams ;
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, 0, activate, 0);
alarams = (AlarmManager) getSystemService(ALARM_SERVICE);
alarams.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis()+5000, alarmIntent);
