Reminder Functionality

In my application i am trying to set reminder and alarm on that reminder but i am not able to do so.

As i don't have complete and proper knowledge of how to set reminder, edit it and delete it. As i searched on google and what i got is not easy to understand for me.

I tried a code as: Main.java

Calendar cal = Calendar.getInstance();
java.util.Calendar;

// add minutes to the calendar object
cal.set(Calendar.MONTH, 4);
cal.set(Calendar.YEAR, 2011);
cal.set(Calendar.DAY_OF_MONTH, 5);
cal.set(Calendar.HOUR_OF_DAY, 21);
cal.set(Calendar.MINUTE, 43);

Intent alarmintent = new Intent(getApplicationContext(), AlarmReceiver.class);
alarmintent.putExtra("title","Title of our Notification");
alarmintent.putExtra("note","Description of our Notification");
//HELLO_ID is a static variable that must be initialised at the BEGINNING OF CLASS with 1;

//example:protected static int HELLO_ID =1;
PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(), HELLO_ID,
alarmintent,PendingIntent.FLAG_UPDATE_CURRENT| Intent.FILL_IN_DATA);
//VERY IMPORTANT TO SET FLAG_UPDATE_CURRENT... this will send correct extra's informations to
//AlarmReceiver Class
// Get the AlarmManager service

AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);


AlarmReceiver.java

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.widget.Toast;

public class AlarmReceiver extends BroadcastReceiver {

private static int NOTIFICATION_ID = 1;

@Override
public void onReceive(Context context, Intent intent) {

NotificationManager manger = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon, "Combi Note", System.currentTimeMillis());
PendingIntent contentIntent = PendingIntent.getActivity(context, NOTIFICATION_ID, new Intent(context, AlarmReceiver.class), 0);
Bundle extras=intent.getExtras();
String title=extras.getString("title");
//here we get the title and description of our Notification

String note=extras.getString("note");
notification.setLatestEventInfo(context, note, title, contentIntent);
notification.flags = Notification.FLAG_INSISTENT;
notification.defaults |= Notification.DEFAULT_SOUND;
//here we set the default sound for our
//notification

// The PendingIntent to launch our activity if the user selects this notification
manger.notify(NOTIFICATION_ID++, notification);
}
}


How to set reminders in calendar, edit them, and delete them.

Thank you.

Answer

I found answer after goggling as, we can set reminder in android device by accessing default using EVENTS and Reminder.

The code is as shown:

public void addReminder(int statrYear, int startMonth, int startDay, int startHour, int startMinut, int endYear, int endMonth, int endDay, int endHour, int endMinuts){ 
    Calendar beginTime = Calendar.getInstance();
    beginTime.set(statrYear, startMonth, startDay, startHour, startMinut);
    long startMillis = beginTime.getTimeInMillis();

    Calendar endTime = Calendar.getInstance();
    endTime.set(endYear, endMonth, endDay, endHour, endMinuts);
    long endMillis = endTime.getTimeInMillis();

    String eventUriString = "content://com.android.calendar/events";
    ContentValues eventValues = new ContentValues();

    eventValues.put(Events.CALENDAR_ID, 1);
    eventValues.put(Events.TITLE, "OCS");
    eventValues.put(Events.DESCRIPTION, "Clinic App");
    eventValues.put(Events.EVENT_TIMEZONE, "Nasik");
    eventValues.put(Events.DTSTART, startMillis);
    eventValues.put(Events.DTEND, endMillis);

    //eventValues.put(Events.RRULE, "FREQ=DAILY;COUNT=2;UNTIL="+endMillis);
    eventValues.put("eventStatus", 1);
    eventValues.put("visibility", 3);
    eventValues.put("transparency", 0); 
    eventValues.put(Events.HAS_ALARM, 1);

    Uri eventUri = getContentResolver().insert(Uri.parse(eventUriString), eventValues);
    long eventID = Long.parseLong(eventUri.getLastPathSegment());

    /***************** Event: Reminder(with alert) Adding reminder to event *******************/

    String reminderUriString = "content://com.android.calendar/reminders";

    ContentValues reminderValues = new ContentValues();

    reminderValues.put("event_id", eventID);
    reminderValues.put("minutes", 1);
    reminderValues.put("method", 1);

    Uri reminderUri = getContentResolver().insert(Uri.parse(reminderUriString), reminderValues);
}   

Hope this answer helps to set reminder in calendar to all.
