问题
I'm trying to add event to default android calendar whithout asking the user for a confirmation of saving the event. (so not with intent)
The following code has no compilation error or run time error. After clicking on the button, no error is shown and no event is added to the Android Calendar App.
I've already check the calendars authorisations in my manifest and check de min sdk version in the graddle (i work on android studio)
public void onAddEventClicked(View view) {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CALENDAR) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_CALENDAR) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
}
else if(ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CALENDAR) == PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_CALENDAR) == PackageManager.PERMISSION_GRANTED) {
ContentResolver cr = getContentResolver();
Calendar beginTime = Calendar.getInstance();
beginTime.set(2018, Calendar.OCTOBER, 27, 13, 30);
Calendar endTime = Calendar.getInstance();
endTime.set(2018, Calendar.OCTOBER, 27, 17, 30);
ContentValues values = new ContentValues();
values.put(CalendarContract.Events.DTSTART, beginTime.getTimeInMillis());
values.put(CalendarContract.Events.DTEND, endTime.getTimeInMillis());
values.put(CalendarContract.Events.TITLE, "doctor");
values.put(CalendarContract.Events.DESCRIPTION, "doctor appointment");
values.put(CalendarContract.Events.CALENDAR_ID, 0);
values.put(CalendarContract.Events.EVENT_TIMEZONE, "Europe/Paris");
values.put(CalendarContract.Events.EVENT_LOCATION, "Paris");
Uri EVENTS_URI = Uri.parse(CalendarContract.Events.CONTENT_URI.toString());
Uri uri = cr.insert(EVENTS_URI, values);
Button b = (Button) findViewById(R.id.addEventButton);
b.setText("Did it worked ?");
}
}

The default calendar id is 3, but you have 0 and that's probably why you don't see that being added to the Calendar.
From the Calendar Provider developer doc, it's hardcoding the calendar id to 3.
long calID = 3;
long startMillis = 0;
long endMillis = 0;
Calendar beginTime = Calendar.getInstance();
beginTime.set(2012, 9, 14, 7, 30);
startMillis = beginTime.getTimeInMillis();
Calendar endTime = Calendar.getInstance();
endTime.set(2012, 9, 14, 8, 45);
endMillis = endTime.getTimeInMillis();
...
ContentResolver cr = getContentResolver();
ContentValues values = new ContentValues();
values.put(Events.DTSTART, startMillis);
values.put(Events.DTEND, endMillis);
values.put(Events.TITLE, "Jazzercise");
values.put(Events.DESCRIPTION, "Group workout");
values.put(Events.CALENDAR_ID, calID);
values.put(Events.EVENT_TIMEZONE, "America/Los_Angeles");
Uri uri = cr.insert(Events.CONTENT_URI, values);
// get the event ID that is the last element in the Uri
long eventID = Long.parseLong(uri.getLastPathSegment());
To make sure 3 is the primary calendar id, you can refer this post for querying the primary/default calendar

This will add an event to the users calendar.
Add permissions to the manifest:
<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<permission android:name="android.permission.READ_CALENDAR" />
<permission android:name="android.permission.WRITE_CALENDAR" />
<permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Add to oncreate:
if(ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_CALENDAR}, 1);
Add to mainactivity: (View view) (MenuItem mi) use for the menu drawer.
public void onAddEventCal(MenuItem mi) {
long calID = 3;
ContentResolver cr = getContentResolver();
Calendar beginTime = Calendar.getInstance();
beginTime.set(2019, Calendar.FEBRUARY, 25, 3, 30);
Calendar endTime = Calendar.getInstance();
endTime.set(2019, Calendar.FEBRUARY, 25, 3, 30);
ContentValues values = new ContentValues();
values.put(CalendarContract.Events.DTSTART, beginTime.getTimeInMillis());
values.put(CalendarContract.Events.DTEND, endTime.getTimeInMillis());
values.put(CalendarContract.Events.TITLE, "Connect Treadmill app");
values.put(CalendarContract.Events.DESCRIPTION, "Treadmill Data");
values.put(CalendarContract.Events.CALENDAR_ID, calID);
values.put(CalendarContract.Events.EVENT_TIMEZONE, "Europe/Paris");
values.put(CalendarContract.Events.EVENT_LOCATION, "Paris");
Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);
Toast.makeText(this, "Calendar Event added", Toast.LENGTH_SHORT).show();
}

I think the problem is in permission try using these code
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CALENDAR) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_CALENDAR) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION},MY_PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);}else if(ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CALENDAR) == PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_CALENDAR) == PackageManager.PERMISSION_GRANTED){
}

This permission request is what I used. You can modify to what permissions you want.
onCreate
// Ask for location && calendar permission if not already allowed
Request_Permissions();
ManActivity
//Request permission
private void Request_Permissions()
{
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_CALENDAR, android.Manifest.permission.ACCESS_COARSE_LOCATION
}, 1);
}

I was getting this issue and then I used following code to get the calendar ID.
private fun getCalendarId(context: Context) : Long? {
val projection = arrayOf(Calendars._ID, Calendars.CALENDAR_DISPLAY_NAME)
var calCursor = context.contentResolver.query(
Calendars.CONTENT_URI,
projection,
Calendars.VISIBLE + " = 1 AND " + Calendars.IS_PRIMARY + "=1",
null,
Calendars._ID + " ASC"
)
if (calCursor != null && calCursor.count <= 0) {
calCursor = context.contentResolver.query(
Calendars.CONTENT_URI,
projection,
Calendars.VISIBLE + " = 1",
null,
Calendars._ID + " ASC"
)
}
if (calCursor != null) {
if (calCursor.moveToFirst()) {
val calName: String
val calID: String
val nameCol = calCursor.getColumnIndex(projection[1])
val idCol = calCursor.getColumnIndex(projection[0])
calName = calCursor.getString(nameCol)
calID = calCursor.getString(idCol)
Log.d("Calendar name = $calName Calendar ID = $calID")
calCursor.close()
return calID.toLong()
}
}
return null
}
So do not pass 0, 1 or 3 as Calendar ID. Use above function instead.
