I am trying to add events to a user's calendar programatically. I have followed countless guides here on StackOverflow and elsewhere, but none of them will make that damned event show up in my calendar. Here is my current code:
public void saveGamesToCalendar() {
showCalendarPopup();
}
private void showCalendarPopup() {
final ContentResolver cr;
final Cursor result;
final Uri uri;
List<String> listCals = new ArrayList<String>();
final String[] projection = new String[] {CalendarContract.Calendars._ID, CalendarContract.Calendars.ACCOUNT_NAME, CalendarContract.Calendars.CALENDAR_DISPLAY_NAME, CalendarContract.Calendars.NAME,};
uri = CalendarContract.Calendars.CONTENT_URI;
cr = context.getContentResolver();
result = cr.query(uri, projection, null, null, null);
if(result.getCount() > 0 && result.moveToFirst()) {
do {
listCals.add(result.getString(result.getColumnIndex(CalendarContract.Calendars.NAME)));
} while(result.moveToNext());
}
CharSequence[] calendars = listCals.toArray(new CharSequence[listCals.size()]);
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Calendar to use:");
builder.setItems(calendars, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog,int itemCal) {
Log.e("SettingsActivity", "CalendarID: " + itemCal);
loopThroughGames(itemCal);
};
});
AlertDialog alert = builder.create();
alert.show();
}
private void loopThroughGames(int whichCalendar) {
ArrayList<Model_Game> games = memoryManager.getGames();
// for(Game e: games)
Log.e("Game", games.get(101).toString());
addGameToCalendar(games.get(101), whichCalendar);
Log.e("ID", "" + whichCalendar);
}
private void addGameToCalendar(Model_Game game,int whichCalendar) {
ContentResolver cr = context.getContentResolver();
ContentValues values = new ContentValues();
try {
values.put(CalendarContract.Events.CALENDAR_ID, whichCalendar);
values.put(CalendarContract.Events.TITLE, "Hockey- " + game.getLeague() + ": " + game.getTeamH() + " vs " + game.getTeamA());
values.put(CalendarContract.Events.EVENT_LOCATION, "Twin Rinks Ice Arena- " + game.getRink() + " Rink");
values.put(CalendarContract.Events.DTSTART, "" + game.getCalendarObject().getTimeInMillis());
//values.put(CalendarContract.Events.DTEND, "" + game.getCalendarObject().getTimeInMillis() + 5400000);
values.put(CalendarContract.Events.DURATION, "" + 5400000);
values.put(CalendarContract.Events.EVENT_TIMEZONE, TimeZone.getDefault().getID());
cr.insert(CalendarContract.Events.CONTENT_URI, values);
} catch(Exception e) {
Log.e("Error", e.getMessage());
toast(e.getMessage());
}
}
Basically what is going on is that the user presses an action bar button, which calls the saveGamesToCalendar() method, which calls the ShowCalendarPopup() method. This method shows a standard dialog with the list of the user's calendars, and when the user selects one of them, the loopThroughGames() method is called with the ID of the chosen calendar as a parameter. This method will, when everything is working, write all the user's games to the calendar, but for testing purposes it only writes one. The addGameToCalendar() method takes a game object, which holds lots of values like time, title, location, date, etc., and inserts it into the calendar using the standard way outlined in many different places on the web.
I am getting no error messages with this code (other than the ones I send to the error log myself) so I have no idea why this code isn't working. No errors, just the games never show up in my calendar. I have the permissions set correctly in the manifest so I know that isn't the problem.
Does anyone have a solution to this annoying problem? Thanks for your help!
[RE-EDIT]]
This is what I did and it works like a charm..
Cursor cursor = null ;
String[] projection = new String[] {
CalendarContract.Calendars._ID,
CalendarContract.Calendars.ACCOUNT_NAME,};
ContentResolver cr = context2.getContentResolver();
cursor = cr.query(Uri.parse("content://com.android.calendar/calendars"), projection, null, null, null);
if ( cursor.moveToFirst() ) {
final String[] calNames = new String[cursor.getCount()];
calIds = new int[cursor.getCount()];
for (int i = 0; i < calNames.length; i++) {
calIds[i] = cursor.getInt(0);
calNames[i] = cursor.getString(1);
cursor.moveToNext();
}
}
try {
ContentValues values = new ContentValues();
// int apiLevel = android.os.Build.VERSION.SDK_INT;
// if(apiLevel<14){

values.put(Events.DTSTART, stTime);
values.put(Events.DTEND, enTime);
values.put(Events.TITLE, category);
values.put(Events.DESCRIPTION, description);
values.put(Events.CALENDAR_ID, calIds[0]);
values.put(Events.EVENT_LOCATION,place);
values.put(Events.EVENT_TIMEZONE,tZone);
mInsert = cr.insert(CalendarContract.Events.CONTENT_URI, values);
Toast.makeText(context2, "Event added Successfully",
Toast.LENGTH_LONG).show();
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(context2, "Exception: " + e.getMessage(),

}
protected void eventAdding() {
try
{
Calendar beginTime = Calendar.getInstance();
beginTime.set(2013, 11, 20, 8,0 );
startMillis = beginTime.getTimeInMillis();
Calendar endTime = Calendar.getInstance();
endTime.set(2013, 11, 20, 8, 50);
endMillis = endTime.getTimeInMillis();
ContentResolver cr = this.getContentResolver();
ContentValues values = new ContentValues();
values.put(Events.DTSTART, startMillis);
values.put(Events.DTEND, endMillis);
values.put(Events.TITLE, "Hello");
values.put(Events.CALENDAR_ID, 1);
values.put(Events.EVENT_TIMEZONE, TimeZone.getDefault().getID());
if (android.os.Build.VERSION.SDK_INT <= 7) {
uri = Uri.parse("content://calendar/events");
} else
{
uri = Uri.parse("content://com.android.calendar/events");
}
Uri urievent = cr.insert(uri, values);
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//event = Utility.readCalendarEvent(CalnderEvent.this);
}
This works and is much easier to understand:
long startTime = calSet.getTimeInMillis();
Intent intent = new Intent(Intent.ACTION_INSERT).setData(Events.CONTENT_URI)
.setData(Events.CONTENT_URI)
.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, startTime)
.putExtra(CalendarContract.EXTRA_EVENT_END_TIME, startTime + (length*3600000))
.putExtra(Events.TITLE, examName)
.putExtra(Events.EVENT_LOCATION, venue)
.putExtra(Events.AVAILABILITY, Events.AVAILABILITY_BUSY)
.putExtra(Events.HAS_ALARM, 1);
startActivity(intent);

The error i am getting in logs is

Event id is created successfully but while inserting uri for reminder is creating sqlite exception . Please help!
Update: I found that this error can be occurred with in two conditions.
If you didn't config your google calendar app in your
phone/emulator this error will occur. Then make sure that you configure the google calendar app with a gmail account before running the app.
If you are passing wrong formatted or false time to the event or reminder. use unix time with correct time zone.
Recently, I also faced same issue. Finally, I found the solution.
First of all, you have to find all logged in gmail id from the device and then select any one gmail account and find its calendar id. After that you have to pass that id to the event query like this....
values.put(Events.CALENDAR_ID, calendarId);
at last call you function
See below method for finding email id's...
public static Hashtable listCalendarId(Context context) {
try {
if (haveCalendarReadWritePermissions((Activity) context)) {
String projection[] = {"_id", "calendar_displayName"};
Uri calendars;
calendars = Uri.parse("content://com.android.calendar/calendars");
ContentResolver contentResolver = c.getContentResolver();
Cursor managedCursor = contentResolver.query(calendars, projection, null, null, null);
if (managedCursor.moveToFirst()) {
String calName;
String calID;
int cont = 0;
int nameCol = managedCursor.getColumnIndex(projection[1]);
int idCol = managedCursor.getColumnIndex(projection[0]);
Hashtable<String, String> calendarIdTable = new Hashtable<>();
do {
calName = managedCursor.getString(nameCol);
calID = managedCursor.getString(idCol);
Log.v(TAG, "CalendarName:" + calName + " ,id:" + calID);
calendarIdTable.put(calName, calID);
cont++;
} while (managedCursor.moveToNext());
managedCursor.close();
return calendarIdTable;
}
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
I'm using below code in Marshmellow device to add the event to the Calendar programmatically but it's not working. Any idea? I cannot see this event in the Calendar app.
long startMillis = 0;
long endMillis = 0;
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date startDate = null, endDate = null;
try{
startDate = simpleDateFormat.parse("2017-05-01 01:30:00");
startMillis = startDate.getTime();
endDate = simpleDateFormat.parse("2017-05-01 03:30:00");
endMillis = endDate.getTime();
}catch (ParseException e){
e.printStackTrace();
}
ContentResolver cr = this.getContentResolver();
ContentValues values = new ContentValues();
TimeZone timeZone = TimeZone.getDefault();
values.put(CalendarContract.Events.DTSTART, startMillis);
values.put(CalendarContract.Events.DTEND, endMillis);
values.put(CalendarContract.Events.EVENT_TIMEZONE, timeZone.getID());
values.put(CalendarContract.Events.TITLE, "Hello Title");
values.put(CalendarContract.Events.DESCRIPTION, "Add events to Calendar");
values.put(CalendarContract.Events.CALENDAR_ID, 879);
Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);
PS: It works if only one gmail account is synced with the calendar app.
Am also find so many solutions finally i got solution and successfully calendar event added with Schedule event.

I have used this method on button click. When I click on the button ArrayList of Events should be added to Default calendar of Android Device. But here in this code, I am unable to see the event that is added to Calendar. And I even think that entry is not being added to calendar.
Thank you.
This is what I use, and it works in my code
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", startDate.getTimeInMillis());
intent.putExtra("endTime", endDate.getTimeInMillis());
intent.putExtra("title", title);
activty.startActivity(intent);
The event is added to android calendar, but it's not checked to see if the same event is already there (possible duplicate of the event)
I facing a events details saving in android calendar from the long time. I am able to save the details in devices below android version 2.2.3 but for above it doesn't save to calendar. Here is my code:

if(getCalendarUriBase(this)!=null)
{
Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
ContentResolver cr = getContentResolver();
// event insert
long eventdate1=Date.parse(“23/07/2012”);
long eventdate2=Date.parse((“23/07/2012”);
ContentValues values = new ContentValues();
values.put("calendar_id", 1);
values.put("title","Event 1");
values.put("allDay", 0);
values.put("dtstart", eventdate1); // event starts at 11 minutes from now
values.put("dtend", eventdate2); // ends 60 minutes from now
values.put("description", "Description 1");
values.put("eventLocation", "xyz");
values.put("visibility", 0);
values.put("hasAlarm", 1);
try{
try{

Where I am missing something. Please help me on it.
I had a similar problem. I think the problem is in
values.put("visibility", 0);
I think that there is no column in database with that name. It's the same with column named transparency. I found it in some tutorials on the net
I am trying to add an event to the android calendar, and I specify that the event will be added to the gmail calendar in order to sync with the Google calendar automatically.
The problem is events added programmatically don't sync with Google calendar, but if I add it manual on the phone it does sync with Google calendar. I don't know why.
This is the code that I use to add the event:
ArrayList<MyCalendar> calendars = new ArrayList<MyCalendar>();
String[] projection = new String[] { "_id", "name" };
Uri calUri = getCalendarURI(false);
Cursor managedCursor = managedQuery(calUri, projection, "selected=1",
null, null);
String calName = null;
String calId = null;
if (managedCursor.moveToFirst()) {
int nameColumn = managedCursor.getColumnIndex("name");
int idColumn = managedCursor.getColumnIndex("_id");
do {
calName = managedCursor.getString(nameColumn);
calId = managedCursor.getString(idColumn);
calendars.add(new MyCalendar(Integer.parseInt(calId), calName));
} while (managedCursor.moveToNext());
}
Toast.makeText(getBaseContext(), calName + " " + calId,
Toast.LENGTH_LONG).show();
Calendar cal = Calendar.getInstance();
ContentValues event = new ContentValues();
event.put("calendar_id", 2);
event.put("title", "Test Event2");
event.put("description", "Hiii Buddy");
long startTime = cal.getTimeInMillis();
long endTime = cal.getTimeInMillis() + 60 * 60 * 1000;
event.put("dtstart", startTime);
event.put("dtend", endTime);
event.put("allDay", 0);
event.put("eventStatus", 1);// tentative 0, confirmed 1 canceled 2
event.put("visibility", 3);// default 0 confidential 1 private 2
// public 3
event.put("transparency", 0);// opaque 0 transparent 1
event.put("hasAlarm", 1); // 0 false, 1 true
Uri eventsUri = getCalendarURI(true);
Uri url = getContentResolver().insert(eventsUri, event);
So the event successfully added to calendar but it doesn't show up in the Google calendar at the web (don't sync) but if I add the event manually it does sync !!!
You can sync your event after adding it by this function,It's worked for me(in API 8 and later):
public static void syncCalendar(Context context, String calendarId) {
ContentResolver cr = context.getContentResolver();
ContentValues values = new ContentValues();
values.put(CalendarContract.Calendars.SYNC_EVENTS, 1);
values.put(CalendarContract.Calendars.VISIBLE, 1);
cr.update(
ContentUris.withAppendedId(getCalendarUri(),
Long.parseLong(calendarId)), values, null, null);
}
Try this code to insert an event into the android calendar as well as google calendar:
ContentValues values = new ContentValues();
cal_id = String.valueOf(p1);
values.put("calendar_id", p1);
values.put("title", title1);
values.put("allDay", 0);
values.put("dtstart", settime);
values.put("dtend", cal.getTimeInMillis()+60*60*1000);
values.put("description", desc1);
values.put("visibility", 0);
values.put("transparency", 0);
values.put("hasAttendeeData", 1);
values.put("hasAlarm", 0);
event = cr.insert(EVENTS_URI, values);
event1=event;
dat1 = event.toString();
long id=-1;
if (event != null)
{
id = Long.parseLong(event.getLastPathSegment());
ContentValues values1 = new ContentValues();
values1.put("event_id", id);
values1.put("method", 1); //METHOD_ALERT
Uri reminder = Uri.parse(getCalendarUriBase(this) + "reminders");
this.getContentResolver().insert(reminder, values1);
if(s.length() > 0 || partmail.length() > 0)
{
//REQUIRES FOLLOWING CODE
This code is used to add the event sync'ed to the google calendar
ContentValues attendees = new ContentValues();
attendees.put("event_id", id);
attendees.put("attendeeEmail", partmail1);
attendees.put("attendeeRelationship", 2);//RELATIONSHIP_ATTENDEE
attendees.put("attendeeStatus", 3); //ATTENDEE_STATUS_INVITED
attendees.put("attendeeType", 1); //TYPE_REQUIRED
id1=(int)id;
alarmid = (int) id;
Uri attendeesUri = null;
if (Integer.parseInt(Build.VERSION.SDK) >= 8 )
{
attendeesUri = Uri.parse("content://com.android.calendar/attendees");
}
else if(Integer.parseInt(Build.VERSION.SDK) < 8)
{
attendeesUri = Uri.parse("content://calendar/attendees");
}
this.getContentResolver().insert(attendeesUri, attendees);
Toast.makeText(this, "Task Scheduled Successfully", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(this, "Could not create Task!", Toast.LENGTH_SHORT);
}
// reminder insert
Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
values = new ContentValues();
values.put( "event_id", id);
values.put( "method", 1 );
values.put( "minutes", 0 );
cr.insert( REMINDERS_URI, values );
Get Calendar's Uri since it differs for API levels such as till 8, greater than 8 and greater than 11.
private String getCalendarUriBase(Context con) {
String calendarUriBase = null;
Uri calendars = Uri.parse("content://calendar/calendars");
Cursor managedCursor = null;
try {
managedCursor = managedQuery(calendars, null, null, null, null);
} catch (Exception e) {
// eat
}
if (managedCursor != null) {
calendarUriBase = "content://calendar/";
} else {
calendars = Uri.parse("content://com.android.calendar/calendars");
try {
managedCursor = managedQuery(calendars, null, null, null, null);
} catch (Exception e) {
// statement to print the stacktrace
}
if (managedCursor != null) {
calendarUriBase = "content://com.android.calendar/";
}
}

}
Use the google calender api provided here
The above reference is somewhat general as Android doesn’t provide an official API. So, another solution more android specific is An Android Tutorial–Programming with Calendar
which contains a working example too. Also, be careful at Permission Declaration like READ_CALENDAR , WRITE_CALENDAR
