direct event insert to attendees table exceotion if sdk versio lower than 19

I am building an application in which I am inserting events directly to the calendar plus I left the possibility to invite someone else and everything is perfectly fine if I execute it on android sdk version 19 and above, on lower versions I get an exception.
Here is the source:
ContentResolver atend = getContentResolver();
ContentValues val = new ContentValues();
val.put(CalendarContract.Attendees.ATTENDEE_NAME, "Bajo");
val.put(CalendarContract.Attendees.ATTENDEE_EMAIL, someonesEmail);
val.put(CalendarContract.Attendees.ATTENDEE_RELATIONSHIP, CalendarContract.Attendees.RELATIONSHIP_ATTENDEE);
val.put(CalendarContract.Attendees.ATTENDEE_TYPE, CalendarContract.Attendees.TYPE_REQUIRED);
val.put(CalendarContract.Attendees.ATTENDEE_STATUS, CalendarContract.Attendees.ATTENDEE_STATUS_INVITED);
val.put(CalendarContract.Attendees.EVENT_ID, eventID);
Uri muri= atend.insert(CalendarContract.Attendees.CONTENT_URI, val);
Log.d("Atendees URI:",muri.toString());
long Aeventid=Long.parseLong(muri.getLastPathSegment());
the Exception:

Can you help me to identify what I miss?

java.lang.ClassCastException: android.view.ViewGroup$LayoutParams cannot be cast to android.widget.LinearLayout$LayoutParams android 4.1.2

I have this Exception only on some devices on android 4.1.2. So, I want to know what is the problem it can be.
Here is stack trace - no one line from my code, only from SDK - exception happens in SDK, so no lines were missed:

In your code you are importing import android.widget.LinearLayout.LayoutParams instead of android.view.ViewGroup.LayoutParams;
so Delete import android.widget.LinearLayout.LayoutParams;
and Add import android.view.ViewGroup.LayoutParams;
