Take a look at this question: StackOverflow

This code worked for me.

Uri eventsUri = Uri.parse("content://com.android.calendar/events");
ContentResolver cr = getContentResolver();
Cursor cursor;
cursor = cr.query(eventsUri, new String[]{ "_id" },"calendar_id=" + 1, null, null);
while(cursor.moveToNext()) {
    long eventId = cursor.getLong(cursor.getColumnIndex("_id"));
    cr.delete(ContentUris.withAppendedId(eventsUri, eventId), null, null);
}
cursor.close();
// Show message
Toast.makeText(getApplicationContext(), "Calendar Cleared!",Toast.LENGTH_LONG).show();
