How to resolve Multiple repeating alarm triggers at the same time

I tried to create an alarm which will trigger on button click and will repeat on 6:00 am in the morning. The first one that i made worked and is working properly but when i added another repeating alarm it triggers the previous alarm at the same time. So my question is how can I make a multi-alarm work properly?

The code for Repeating alarm

 public void setAlarmRepeating()
    {
        AlarmManager dog=(AlarmManager)this.getSystemService(Context.ALARM_SERVICE);
        Intent alarm_dog=new Intent(this,Dog_alarm.class);
        PendingIntent pi1 = PendingIntent.getBroadcast(this, 100,alarm_dog, PendingIntent.FLAG_UPDATE_CURRENT);
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, 6);
        calendar.set(Calendar.MINUTE,0);
        calendar.set(Calendar.SECOND, 00);
        dog.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi1);


        AlarmManager dog1=(AlarmManager)this.getSystemService(Context.ALARM_SERVICE);
        Intent alarm_dog1=new Intent(this,Dog_alarm.class);
        PendingIntent pi2 = PendingIntent.getBroadcast(this, 200,alarm_dog1, PendingIntent.FLAG_UPDATE_CURRENT);
        Calendar calendar1 = Calendar.getInstance();
        calendar1.set(Calendar.HOUR_OF_DAY, 7);
        calendar1.set(Calendar.MINUTE,0);
        calendar1.set(Calendar.SECOND, 00);
        dog1.setRepeating(AlarmManager.RTC_WAKEUP,calendar1.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi2);

    }

And this is for BroadcastReciever

 public class MorningAlarm extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
        NotificationManager notificationManager1=(NotificationManager)context.getSystemService(context.NOTIFICATION_SERVICE);
        Intent dog_intent1=new Intent(context,HomeActivity.class);
        dog_intent1.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent dog_pending1=PendingIntent.getActivity(context, 100,dog_intent1, PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder builder1=new NotificationCompat.Builder(context)
                .setContentIntent(dog_pending1)
                .setSmallIcon(android.R.drawable.ic_dialog_alert)
                .setContentTitle("Pet Guide 101")
                .setContentText("Time to feed your dog")
                .setAutoCancel(true);
        notificationManager1.notify(100,builder1.build());



        NotificationManager notificationManager2=(NotificationManager)context.getSystemService(context.NOTIFICATION_SERVICE);
        Intent dog_intent2=new Intent(context,HomeActivity.class);
        dog_intent2.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent dog_pending2=PendingIntent.getActivity(context, 200,dog_intent2, PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder builder2=new NotificationCompat.Builder(context)
                .setContentIntent(dog_pending2)
                .setSmallIcon(android.R.drawable.ic_dialog_alert)
                .setContentTitle("Pet Guide 101")
                .setContentText("Time to walk your dog")
                .setAutoCancel(true);
        notificationManager2.notify(200,builder2.build());
    }
}

I think this is because your alarm manager is not taking your task as time critical

you need to use setInexactRepeating() instead of setRepeating() function.

hope it will work.

When you using PendingIntent.FLAG_UPDATE_CURRENT as flag the current PendingIntent update to new extras and no new PendingIntent created.

You must create new PendingIntent for each alarm.

Use:

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

Remember for canceling alarms you must restart your device or uninstall your app
