Android add calendar event Programatically | Android Codes: Insertion and Deletion of Calendar Events | Configure email notification with Calendar app in Android

Hello Friends,
          Today, I am sharing my another android tutorial which covers following things:

1. Android- Adding events to calendar via your android application
2. Programmatically add reminder in android calendara
3. Configure email notification with Calendar app in Android


A. For adding event on Calendar

view plainprint?

1. try {  
2.  String eventUriString = "content://com.android.calendar/events";  
3.  ContentValues eventValues = new ContentValues();  
4.  eventValues.put("calendar_id", 1); // id, We need to choose from  
5.      // our mobile for primary its 1  
6.  eventValues.put("title", title);  
7.  eventValues.put("description", desc);  
8.  eventValues.put("eventLocation", place);  
9.   
10.  long endDate = startDate + 1000 * 10 * 10; // For next 10min  
11.  eventValues.put("dtstart", startDate);  
12.  eventValues.put("dtend", endDate);  
13.   
14.  // values.put("allDay", 1); //If it is bithday alarm or such  
15.  // kind (which should remind me for whole day) 0 for false, 1  
16.  // for true  
17.   eventValues.put("eventStatus", status); // This information is  
18.    // sufficient for most  
19.    // entries tentative (0),  
20.    // confirmed (1) or canceled  
21.    // (2):  
22.  eventValues.put("eventTimezone", "UTC/GMT +5:30");  
23.  /* 
24.   * Comment below visibility and transparency column to avoid 
25.   * java.lang.IllegalArgumentException column visibility is invalid 
26.   * error 
27.   */  
28.  // eventValues.put("allDay", 1);  
29.  // eventValues.put("visibility", 0); // visibility to default (0),  
30.    // confidential (1), private  
31.    // (2), or public (3):  
32.    // eventValues.put("transparency", 0); // You can control whether  
33.    // an event consumes time  
34.    // opaque (0) or transparent  
35.    // (1).  
36.  eventValues.put("hasAlarm", 1); // 0 for false, 1 for true  
37.   
38.  Uri eventUri = curActivity.getApplicationContext()  
39.     .getContentResolver()  
40.     .insert(Uri.parse(eventUriString), eventValues);  
41.  eventID = Long.parseLong(eventUri.getLastPathSegment());   
42. } catch (Exception ex) {  
43.  log.error("Error in adding event on calendar" + ex.getMessage());  
44. }  

try {
 String eventUriString = "content://com.android.calendar/events";
 ContentValues eventValues = new ContentValues();
 eventValues.put("calendar_id", 1); // id, We need to choose from
     // our mobile for primary its 1
 eventValues.put("title", title);
 eventValues.put("description", desc);
 eventValues.put("eventLocation", place);

 long endDate = startDate + 1000 * 10 * 10; // For next 10min
 eventValues.put("dtstart", startDate);
 eventValues.put("dtend", endDate);

 // values.put("allDay", 1); //If it is bithday alarm or such
 // kind (which should remind me for whole day) 0 for false, 1
 // for true
  eventValues.put("eventStatus", status); // This information is
   // sufficient for most
   // entries tentative (0),
   // confirmed (1) or canceled
   // (2):
 eventValues.put("eventTimezone", "UTC/GMT +5:30");
 /*
  * Comment below visibility and transparency column to avoid
  * java.lang.IllegalArgumentException column visibility is invalid
  * error
  */
 // eventValues.put("allDay", 1);
 // eventValues.put("visibility", 0); // visibility to default (0),
   // confidential (1), private
   // (2), or public (3):
   // eventValues.put("transparency", 0); // You can control whether
   // an event consumes time
   // opaque (0) or transparent
   // (1).
 eventValues.put("hasAlarm", 1); // 0 for false, 1 for true

 Uri eventUri = curActivity.getApplicationContext()
    .getContentResolver()
    .insert(Uri.parse(eventUriString), eventValues);
 eventID = Long.parseLong(eventUri.getLastPathSegment()); 
} catch (Exception ex) {
 log.error("Error in adding event on calendar" + ex.getMessage());
}

B. Set Reminder for above added event id:

view plainprint?

1. if (needReminder) {  
2. /***************** Event: Reminder(with alert) Adding reminder to event *******************/  
3.         String reminderUriString = "content://com.android.calendar/reminders";  
4.  ContentValues reminderValues = new ContentValues();  
5.  reminderValues.put("event_id", eventID);  
6.  reminderValues.put("minutes", 5); // Default value   
7.        //set time in min which occur before event start     
8.  reminderValues.put("method", 1); // Alert Methods: Default(0),  
9.      // Alert(1), Email(2),SMS(3)  
10.  Uri reminderUri = curActivity.getApplicationContext()  
11.       .getContentResolver()  
12.     .insert(Uri.parse(reminderUriString), reminderValues);  
13. }  
14.    

if (needReminder) {
/***************** 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", 5); // Default value 
       //set time in min which occur before event start   
 reminderValues.put("method", 1); // Alert Methods: Default(0),
     // Alert(1), Email(2),SMS(3)
 Uri reminderUri = curActivity.getApplicationContext()
      .getContentResolver()
    .insert(Uri.parse(reminderUriString), reminderValues);
}
 

C: Send mail to user for attending the meeting added on calendar

view plainprint?

1. /***************** Event: Meeting(without alert) Adding Attendies to the meeting *******************/  
2.   
3. if (needMailService) {  
4.  String attendeuesesUriString = "content://com.android.calendar/attendees";  
5.   
6.  /******** 
7.   * To add multiple attendees need to insert ContentValues 
8.   * multiple times 
9.   ***********/  
10.  ContentValues attendeesValues = new ContentValues();  
11.  attendeesValues.put("event_id", eventID);  
12.  attendeesValues.put("attendeeName", "xxxxx"); // Attendees name  
13.  attendeesValues.put("attendeeEmail", "yyyy@gmail.com");// Attendee email  
14.  attendeesValues.put("attendeeRelationship", 0); // Relationship_Attendee(1),  
15.        // Relationship_None(0),  
16.        // Organizer(2),  
17.        // Performer(3),  
18.        // Speaker(4)  
19.  attendeesValues.put("attendeeType", 0); // None(0), Optional(1),  
20.       // Required(2),  
21.       // Resource(3)  
22.  attendeesValues.put("attendeeStatus", 0); // NOne(0),  
23.           // Accepted(1),  
24.         // Decline(2),  
25.         // Invited(3),  
26.         // Tentative(4)  
27.   
28.  Uri eventsUri = Uri.parse("content://calendar/events");  
29.  Uri url = curActivity.getApplicationContext()  
30.     .getContentResolver()  
31.     .insert(eventsUri, attendeesValues);  
32.   
33.  // Uri attendeuesesUri = curActivity.getApplicationContext()  
34.     // .getContentResolver()  
35.     // .insert(Uri.parse(attendeuesesUriString), attendeesValues);  
36. }   

/***************** Event: Meeting(without alert) Adding Attendies to the meeting *******************/

if (needMailService) {
 String attendeuesesUriString = "content://com.android.calendar/attendees";

 /********
  * To add multiple attendees need to insert ContentValues
  * multiple times
  ***********/
 ContentValues attendeesValues = new ContentValues();
 attendeesValues.put("event_id", eventID);
 attendeesValues.put("attendeeName", "xxxxx"); // Attendees name
 attendeesValues.put("attendeeEmail", "yyyy@gmail.com");// Attendee email
 attendeesValues.put("attendeeRelationship", 0); // Relationship_Attendee(1),
       // Relationship_None(0),
       // Organizer(2),
       // Performer(3),
       // Speaker(4)
 attendeesValues.put("attendeeType", 0); // None(0), Optional(1),
      // Required(2),
      // Resource(3)
 attendeesValues.put("attendeeStatus", 0); // NOne(0),
          // Accepted(1),
        // Decline(2),
        // Invited(3),
        // Tentative(4)

 Uri eventsUri = Uri.parse("content://calendar/events");
 Uri url = curActivity.getApplicationContext()
    .getContentResolver()
    .insert(eventsUri, attendeesValues);

 // Uri attendeuesesUri = curActivity.getApplicationContext()
    // .getContentResolver()
    // .insert(Uri.parse(attendeuesesUriString), attendeesValues);
} 

D: For deletion of calendar event: Here "id" is event id.

view plainprint?

1. Uri uri = ContentUris.withAppendedId(CALENDAR_URI, Integer.parseInt(id));  
2. getContentResolver().delete(uri, null, null);   

Uri uri = ContentUris.withAppendedId(CALENDAR_URI, Integer.parseInt(id));
getContentResolver().delete(uri, null, null); 

Finally All together: Add this method in your activity class

view plainprint?

1. public long addAppointmentsToCalender(Activity curActivity, String title,  
2.    String desc, String place, int status, long startDate,  
3.    boolean needReminder, boolean needMailService) {

6. try {

8.  ContentValues eventValues = new ContentValues();  
9.  eventValues.put("calendar_id", 1); // id, We need to choose from

11.  eventValues.put("title", title);  
12.  eventValues.put("description", desc);  
13.  eventValues.put("eventLocation", place);  
14.

Also need to add following permission in your AndroidManifest.xml file

view plainprint?

1. <uses-permission android:name="android.permission.READ_CALENDAR" />  
2. <uses-permission android:name="android.permission.WRITE_CALENDAR" />  

<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />

Hope this will help some one.

Enjoy Coding :)
