how to cancel multiple alarm using other activity

Create note Activity from where Alarm trigger! and Alarm delete code in other Activity,it delete only last trigger Alarm means if 3 Alarm are created and I want to delete Alarm 1 it deletes but when the time of Alarm 1 reaches it trigger while it already deleted and it wont trigger other Alarm 2 and 3, on static broadcast id it trigger only last alarm for example alarm 3 trigger delete code in other activity if it delete on using same pending intent in other activity how can i use the pending intent which use trigger alarm in my delete alarm activity
AlarmManager alarmMgr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(getApplicationContext(), AlarmReceiver.class);
String alertTitle = mTitleText.getText().toString();
intent.putExtra(getString(R.string.alert_title), alertTitle);
// broadcastCode++;
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), broadcastCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmMgr.set(AlarmManager.RTC_WAKEUP, calender.getTimeInMillis(), pendingIntent);
cv.put(mDbHelper.TIME, timeString);
cv.put(mDbHelper.DATE, dateString);
public void delete(int id)
{
db.delete( DbHelper.TABLE_NAME, DbHelper.C_ID + "="+id, null);
db.close();
Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), CreateNote.broadcastCode, intent, 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
}

The PendingIntent needs to be created exactly as it was when you started the AlarmManager.
Use PendingIntent.FLAG_UPDATE_CURRENT instead of 0 when creating the PendingIntent to cancel the alarm. FLAG_UPDATE_CURRENT is equal to the constant 134217728, not 0.

Use this code:
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, _id, intent, 0);
AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
Hope this helps.

Canceling alarms from AlarmManager

I am working on application which is get the alarm time from database every 2 AM and then at the specified time the activity shows up, my app works fine, but when I manually change the data/time of the device, previous alarms are triggered and I should prevent to this to happens.
Here is my PendingIntent:
Intent i = new Intent(mContext, AlarmReceiver.class);
PendingIntent pi = PendingIntent.getBroadcast(G.context, _id, i,
PendingIntent.FLAG_UPDATE_CURRENT);
Which each _id is unique and when I make a receiver for date changed event before my alarm cancel method fired previous alarms go off!
Can some body help to solve this problem?

Try this code:
Intent intent = new Intent(this, Mote.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 1253, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); alarmManager.cancel(pendingIntent);

For cancel the alarm:
Intent intent = new Intent(this, Mote.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 1253, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.cancel(pendingIntent);

mAlarmManager.cancel(pendingIntent);
pendingIntent.cancel();

Run Broadcastreceiver for specified time

I am new to android, I want to run a task only for a specific duration, how can I do this?
I tried using broadcast receiver and AlarmManager but the broadcastreceiver continuously runs even after specified time.
long timetorun= calendarcurrent.getTimeInMillis() - calendar.getTimeInMillis();
Intent c = new Intent(getApplicationContext(),
Phonecallreceiver.class);
pintent = PendingIntent.getBroadcast(getApplicationContext(), 0, c, 0);
AlarmManager alarm = (AlarmManager) getSystemService(ALARM_SERVICE);
alarm.set(AlarmManager.RTC_WAKEUP, timetorun, pintent);

You can stop it by canceling the alarm, using the same PendingIntent like the below:
Intent c = new Intent(getApplicationContext(), Phonecallreceiver.class);
pintent = PendingIntent.getBroadcast(getApplicationContext(), 0, c, 0);
AlarmManager alarm = (AlarmManager) getSystemService(ALARM_SERVICE);
alarm .cancel(pintent);
Do not forget to make sure that the PendingIntent is not NULL.
Hope that I helped you.

intent pass the same values to service class

I have to pass intent values to service class but every time intent take the same value as it took at very first time but i need every time different intent values.
Intent alarmIntent = new Intent(AppointmentActivity.this,
AlarmService.class);
alarmIntent.putExtra("appDate", appDateString);
alarmIntent.putExtra("appTime", appoint_time);
alarmIntent.putExtra("appDesc", appoint_desc);
alarmIntent.putExtra("appRemind", appoint_remind);
sender = PendingIntent.getService(AppointmentActivity.this, 0,
alarmIntent, 0);
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), sender);

Replace the PendingIntent.getService to:
sender = PendingIntent.getService(AppointmentActivity.this, 0, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
See if it works.
The Flag is important and 0 might not be an allowed value.

How to cancel this repeating alarm?

I'm writing something like a reminder for users. Users will set reminders for their events, when the time comes, a repeating alarm will be set to trigger a status bar notification. But the alarm seems non-stop after I selected the notification or cleared the notification. I am not sure where to cancel this repeating alarm. Below are some of the codes:
Set up the repeating alarm in my main activity
alarmTime = Calendar.getInstance();
Intent intent = new Intent(this, AlarmReceive.class);
PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmTime.add(Calendar.MINUTE,offset_time);
//Schedule the alarm
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, alarmTime.getTimeInMillis(), 30 * 1000, sender);
In my OnReceive method, I just display the notification in status bar and set the flag as FLAG_AUTO_CANCEL
manager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
// Set the icon, scrolling text and timestamp
Notification notification = new Notification(R.drawable.medical, text, System.currentTimeMillis());
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, i, 0);
notification.flags = Notification.FLAG_AUTO_CANCEL;
manager.notify(R.string.service_text, notification);
How can I stop the alarm when the user selects the notification or clears it?

Call cancel() on AlarmManager with an equivalent PendingIntent to the one you used with setRepeating():
Intent intent = new Intent(this, AlarmReceive.class);
PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.cancel(sender);

I tried various methods and couldnt get it to work, so I decided to do a dirty trick. When I want to cancel my repeating alarm, I use the same method that created my alarm (and hence replacing the old one) and then cancel it right away. With this method if the boolean variable is set to true it creates an alarm ow it replaces and then cancels the replacement which has the same id:
static void CancelRepeatingAlarm(Context context, boolean creating){
//if it already exists, then replace it with this one
Intent alertIntent = new Intent(context, AlertReceiver.class);
PendingIntent timerAlarmIntent = PendingIntent
.getBroadcast(context, 100, alertIntent,PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
if (creating){
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), INTERVAL, timerAlarmIntent);
}else{
alarmManager.cancel(timerAlarmIntent);
}

In your MainActivity, set the alarm time. If you're going to use multiple alarms, use SharedPreferences to store their respective IDs. Here is the code:
PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, _id,intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager = (AlarmManager) getSystemService(Activity.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),
pendingIntent);
public static Context getContext() {
return mContext;
}
mContext=mainactivity.this;
In your second Activity use same ID from SharedPreferences. In my code, I get the ID from the ArrayList, Alarm_id. Last, you can use the MainActivity context here with MainActivity.getContext(). Here is the code:
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intentAlarm = new Intent(AlarmListviewActivity.this,
MainActivity.class);
PendingIntent morningIntent = PendingIntent.getBroadcast(MainActivity.getContext(), Alarm_id.get(positon),
intentAlarm, PendingIntent.FLAG_CANCEL_CURRENT);
alarmManager.cancel(morningIntent);
morningIntent.cancel();
