How to add multiple event to android marshmallow Calendar?

Events are adding to calendar properly till api 22.
I have also implemented run- time permissions for Marshmallow , Calender permission is allowed in Phone setting for my application is clearly visible.
But still nothing is updating on phone calendar and also app giving no error or warning.
Below is my method to add event programatically on phone calendar.
private void addEventToCalender(Activity ourActivity, String title, String desc, String place, int status, long startDate, long endDte, boolean needReminder, boolean needMailService) {
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", "My Title");
eventValues.put("description","My Description" );
eventValues.put("eventLocation", "Noida,UP ";
eventValues.put("dtstart", startDate);
eventValues.put("dtend", endDte);
eventValues.put("allDay", 1); // 1 for whole day
//eventValues.put("rrule", "FREQ=YEARLY");
// 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", 1); // This information is
// sufficient for most
// entries tentative (0),
// confirmed (1) or canceled
// (2):
eventValues.put("eventTimezone", "UTC/GMT " + Constants.tzone);
eventValues.put("hasAlarm", 1); // 0 for false, 1 for true
Uri eventUri = this.getApplicationContext().getContentResolver().insert(Uri.parse(eventUriString), eventValues);
long eventID = Long.parseLong(eventUri.getLastPathSegment());
Log.i("eventID", eventID + "");
showSnackBar("Event added to calender successfuly.");
} catch (Exception ex) {
Log.e("error", "Error in adding event on calendar" + ex.getMessage());
showSnackBar("Ünable to add event to calender!");
}
}

May be you want to use inside Fragment .
at first use :
super.requestPermissions( new String[]{Manifest.permission.WRITE_CALENDAR}, MY_PERMISSIONS_REQUEST_WRITE_CALENDAR);
Inside fragment, you need to call:
FragmentCompat.requestPermissions(permissionsList, RequestCode)
Note:
ActivityCompat.requestPermissions(Activity, permissionsList, RequestCode);
add this library for FragmentCompat class in app.gradle.
compile 'com.android.support:support-v13:version_of_library'

But in calendar application it is visible for an second and disappears,i have no clue what is going wrong, i have made the visible flag with 1 on insertion but still not working.Can someone Help.

I'm making a simple Dashclock Calendar extension, and it stopped updating

I'm making a basic Dashclock extension that polls CalendarContract.Events for a list of all calendar events synced to the user's device, retrieve the one that's scheduled to happen the soonest, and post the time, title, location, and desctiption. Here's my code:
public class FullCalService extends DashClockExtension {
public static final String[] FIELDS = { Events._ID, Events.TITLE,
Events.ALL_DAY, Events.EVENT_LOCATION, Events.DTSTART,
Events.EVENT_TIMEZONE, Events.DESCRIPTION };
public FullCalService() {
}
#Override
protected void onUpdateData(int arg0) {
TimeZone tz = TimeZone.getDefault();
long currentTimeMillis = Calendar.getInstance().getTimeInMillis() - tz.getRawOffset();
SharedPreferences prefs = PreferenceManager
.getDefaultSharedPreferences(this);
Cursor c;
if (prefs.getBoolean("allDayAllowed", false)) {
c = getContentResolver().query(
Events.CONTENT_URI,
FIELDS,
new StringBuilder().append("(").append(Events.DTSTART)
.append(" >= ?)").toString(),
new String[] { Long.toString(currentTimeMillis) },
Events.DTSTART, null);
} else {
c = getContentResolver().query(
Events.CONTENT_URI,
FIELDS,
new StringBuilder().append("((").append(Events.ALL_DAY)
.append("= ?) AND (").append(Events.DTSTART)
.append(" >= ?))").toString(),
new String[] { Integer.toString(0),
Long.toString(currentTimeMillis) }, Events.DTSTART,
null);
}
if (c.moveToFirst()) {
long eventTimeMillis = c.getLong(c.getColumnIndex(Events.DTSTART));
// if (tz.inDaylightTime(new Date(eventTimeMillis))) {
// eventTimeMillis += tz.getDSTSavings();
// }
//Log.d("DesCal service", "Value of hoursToReveal: "+prefs.getString("hoursToReveal", "1"));
if (eventTimeMillis < currentTimeMillis + 360000
* Integer.parseInt(prefs.getString("hoursToReveal", "1"))) {
String title = c.getString(c.getColumnIndex(Events.TITLE));
String loc = c.getString(c
.getColumnIndex(Events.EVENT_LOCATION));
String time = DateUtils.formatDateTime(this, eventTimeMillis,
DateUtils.FORMAT_SHOW_TIME);
String desc = c.getString(c.getColumnIndex(Events.DESCRIPTION));
StringBuilder expandedBody = new StringBuilder(time);
if (!loc.isEmpty()){
expandedBody.append(" - ").append(loc);
}
expandedBody.append("\n").append(desc);
String uri = new StringBuilder(
"content://com.android.calendar/events/").append(
c.getLong(c.getColumnIndex(Events._ID))).toString();
publishUpdate(new ExtensionData()
.visible(true)
.status(time)
.expandedTitle(title)
.expandedBody(expandedBody.toString())
.icon(R.drawable.ic_dash_cal)
.clickIntent(
new Intent(Intent.ACTION_VIEW, Uri.parse(uri))));
c.close();
} else {
publishUpdate(new ExtensionData().visible(false));
c.close();
}
} else {
publishUpdate(new ExtensionData().visible(false));
c.close();
}
}
}
Upon first install, it appeared to work just fine. However, after the event began, it would not grab any future events. Is there a reason why the extension will not refresh itself?

How are you triggering further updates? You need to manually specify when you'd like to have onUpdateData called, e.g. when there's a change to a content provider, or when the screen turns on, etc. Extensions by default refresh only every 30 minutes or so. See the source for the built in calendar extension for example code.

Check if the event exists before adding it to the Android calender

I have a list of events in my app. A button on the side lets the user add the event date and time to his/her calender. I use a calender intent to redirect the user to the android calender which the corresponding date and time. Now after the user adds the event to his calender, I would like to disable the 'add event' button which corresponds to the events he/she had already added(so the user avoid adding the same event again). How can I do this? I have gone through the new calender API for android 4.0 but I wasnt able to achieve what I wanted.
Basically what I want is to avoid repeated entries for the same event in the users calender.
Any help would be appreciated.

You should test, if an instance for this event exists. See the documentation of the Android's CalendarContract.Instances class.
Especially the second query method should be helpful in this case.
This examples is some code, I posted on my blog post about the CalendarContract provider - slightly altered for your needs:
long begin = // starting time in milliseconds
long end = // ending time in milliseconds
String[] proj =
new String[]{
Instances._ID,
Instances.BEGIN,
Instances.END,
Instances.EVENT_ID};
Cursor cursor =
Instances.query(getContentResolver(), proj, begin, end, "\"Your event title\"");
if (cursor.getCount() > 0) {
// deal with conflict
}
Be aware: The time is always in UTC millis since the epoch. So you might have to adjust given the user's timezone.
And the last parameter should contain the title of the event you have added to the calendar. Keep the quotes - otherwise Android looks for "your" or "event" or "title"!
And do not forget to include the necessary permissions.

Instances.query is not recommended to be run on the UI thread, but can be done efficiently by ensuring start and end time duration is minimized.
The search string will search all values, not just title, so adding a loop to check for that an exact field value is necessary.
public boolean eventExistsOnCalendar(String eventTitle, long startTimeMs, long endTimeMs) {
if (eventTitle == null || "".equals(eventTitle)) {
return false;
}
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CALENDAR) != PackageManager.PERMISSION_GRANTED) {
return false;
}
// If no end time, use start + 1 hour or = 1 day. Query is slow if searching a huge time range
if (endTimeMs <= 0) {
endTimeMs = startTimeMs + 1000 * 60 * 60; // + 1 hour
}
final ContentResolver resolver = mContext.getContentResolver();
final String[] duplicateProjection = {CalendarContract.Events.TITLE}; // Can change to whatever unique param you are searching for
Cursor cursor =
CalendarContract.Instances.query(
resolver,
duplicateProjection,
startTimeMs,
endTimeMs,
'"' + eventTitle + '"');
if (cursor == null) {
return false;
}
if (cursor.getCount() == 0) {
cursor.close();
return false;
}
while (cursor.moveToNext()) {
String title = cursor.getString(0);
if (eventTitle.equals(title)) {
cursor.close();
return true;
}
}
cursor.close();
return false;
}

I have used following way to check it ...what i am passing event_id to check whether is it in calendar or not....
public boolean isEventInCal(Context context, String cal_meeting_id) {
Cursor cursor = context.getContentResolver().query(
Uri.parse("content://com.android.calendar/events"),
new String[] { "_id" }, " _id = ? ",
new String[] { cal_meeting_id }, null);
if (cursor.moveToFirst()) {
//Yes Event Exist...
return true;
}
return false;
}

Please check this, this might help:
private static boolean isEventInCalendar(Context context, String titleText, long dtStart, long dtEnd) {
final String[] projection = new String[]{CalendarContract.Instances.BEGIN, CalendarContract.Instances.END, CalendarContract.Instances.TITLE};
Cursor cursor = CalendarContract.Instances.query(context.getContentResolver(), projection, dtStart, dtEnd);
return cursor != null && cursor.moveToFirst() && cursor.getString(cursor.getColumnIndex(CalendarContract.Instances.TITLE)).equalsIgnoreCase(titleText);
}

write in the android calendar

As part of a project, I created an android application which communicates with an online database (MySQL) to integrate the appointment has taken the online calendar.
I collect the data, converted to Json, but when the inscrires in the agenda of android mobile I encounter a probleme, here is my code : (sorry for my english )
EDIT :
public class calendrier extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Cursor cursor = getContentResolver()
.query(Uri.parse("content://com.android.calendar/calendars"),
new String[] { "_id", "displayName" }, "selected=1",
null, null);
if (cursor != null && cursor.moveToFirst()) {
String[] calNames = new String[cursor.getCount()];
int[] 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();
}
cursor.close();
if (calIds.length > 0) {
// we're safe here to do any further work
}
// grab calendar id from above
int cal_id = calIds[0];
// set the content value
ContentValues cv = new ContentValues();
cv.put("calendar_id", cal_id);
cv.put("title", "titre");
cv.put("description", "bla bla bla");
cv.put("eventLocation", "city");
// note: you're going to need to convert the desired date into
// milliseconds
cv.put("dtstart", System.currentTimeMillis());
cv.put("dtend", System.currentTimeMillis()
+ DateUtils.DAY_IN_MILLIS);
cv.put("allDay", 0); // true = 1, false = 0
cv.put("hasAlarm", 1);
// once desired fields are set, insert it into the table
getContentResolver().insert(
Uri.parse("content://com.android.calendar/events"), cv);
}
}
}
this code works but it asks me if I want to participate in the event when I open it and I wish he does not do
thanks

//did U include permission in your manifest.xml file
android.permission.READ_CALENDAR
android.permission.WRITE_CALENDAR
String WRITE_CALENDAR Allows an application to write (but not read) the user's calendar data.

The Uri of Calendar has changed from Android 2.2 .
Old (2.1 and before): content://calendar/
New (2.2): content://com.android.calendar/
Change your Uri to the new one.
There is no Calendar Application by default in Android. So the Uri may not work at all.
If, you are getting the first error message as "Failed to find provider info for com.android.calendar", you need to check the handset you are using to debug uses which Calendar URI.
To insert Time in Calendar event, you can use the following code example:
Calendar calendar = Calendar.getInstance();
calendar.getTimeInMillis();
cv.put("dtstart", ""+calendar.getTimeInMillis());
cv.put("dtend", ""+calendar.getTimeInMillis()+10000);
