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?

Android - Is there any reason why my app should crash when I add a sound file to raw?

My app crashes when I try to open in. The only change I've made was adding a .ogg file to my res/raw directory. It's really weird. I haven't added any codes or made any other changes. I just dragged a sound file into raw and compiled. It just keeps saying "unfortunately blah has stopped". Are there any obvious things I should check?
MainActivity.onCreate:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.engine_layout);
myEngineView = (EngineView) findViewById(R.id.engineviewid);
myEngineView.setKeepScreenOn(true);
}
I get this in logcat:

I read so many threads about memory leaks, memory errors (for instance java.lang.OutOfMemoryError: bitmap size exceeds VM budget - Android) but I didn't succeed in solving my problem
When I remplace image2.setImageResource(R.drawable.fire); by image2.setImageResource(R.drawable.fire1); where fire1 is a simple png, everything works fine
What could I do to solve my problem

To remove OutOfMemory error, you should focus on scaling. You can find at http://developer.android.com/training/displaying-bitmaps/load-bitmap.html

Android Logcat error message.

These error messages appear when I run my Application. It doesn't affect the execution of the application though. The app is based on Android 4 ( API Level 14), it has some code to call a web service, and the build path has http-commons library.

If you google for initializeJavaContextClassLoader NullPointerException you'll find you are definitely not the only one running into this. The solution isn't really clear though.
Have you tried doing a Project -> Clean and rebuilding?

thanks

You are trying to use a reference to null (e.g. variable uninitialized, etc..) in CameraMap.GalleryCamera,onCreate() method, line 20.
Please post code for this method (and indicate line number 20).
