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:

This happens when the build library classes conflict with those at run-time. Try performing a Clean of your project followed by a build.

Android compatibility issues (Api 8, ActionbarSherlock)

I'm trying to set-up a basic structure for my project, which is supposed to run on API-levels 8 - 16, uses google location services and ActionBarSherlock.
See my other question for the setup.
I generated a simple activity with Eclipse (Master-Detail-Flow). My project currently has just one Activity and one Fragment. All I did so far is replacing the super classes with their ABS counterparts:
public class CouponListActivity extends SherlockFragmentActivity implements CouponListFragment.Callbacks {
...
}
and
public class CouponListFragment extends SherlockListFragment {
...
}
This is the one and only layout-element I'm using
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:name="....activity.CouponListFragment"
android:id="#+id/coupon_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
tools:context=".CouponListActivity" />
This runs fine on an emulator on API 16, but fails on another emulator with API 8.
The problem is that I cannot interpret the stacktrace in any helpful way. My code does not the seem to get touched at all...

Where can I start looking for the problem? Let me know if I can provide more information.
Update: I have the exact same stacktrace if I rule out ABS and simply try to create a List-Activity / -Fragment combination that runs in API 8. Here is the project.

After reviewing your source code, you are using simple_list_item_activated_1 resource. Which was new to Android API level 11 So Solution for your problem is.
onCreate method should be something like this
#Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<DummyContent.DummyItem>(getActivity(), android.R.layout.simple_list_item_activated_1,android.R.id.text1, DummyContent.ITEMS));
}
Since this was new to API Level 11, You will get same error with or without ActionBarSherlock. If you want to use simple_list_item_activated_1 then you need to create a local copy of it. Sorry for being late
