Answer 1

Finally I found the appropriate solution..Much thanks to this How to modify existing Contact

The secret is that you have to pass two values for .withSelection as shown below:

.withSelection(Data.RAW_CONTACT_ID + " = ?", new String[] {String.valueOf(id)})
.withSelection(Data._ID + " = ?", new String[] {mDataId})

where by Data._ID value mDataId is obtained this way:

Cursor mDataCursor = this.context.getContentResolver().query(
                        Data.CONTENT_URI,
                        null,
                        Data.RAW_CONTACT_ID + " = ? AND " + Data.MIMETYPE + " = ?",
                        new String[] { String.valueOf(id), ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE},
                        null);

                if(mDataCursor.getCount() > 0) {
                    mDataCursor.moveToFirst();
                    mDataId = getCursorString(mDataCursor, Data._ID);
                    MLog.v("Data", "Found data item with MIMETYPE");                            
                    mDataCursor.close();

                } else {
                    MLog.v("Data", "Data doesn't contain MIMETYPE");
                    result = ERROR;
                    mDataCursor.close();
                } 

And getCursorString method is something like:

private static String getCursorString(Cursor cursor, String columnName) {
        int index = cursor.getColumnIndex(columnName);
        if(index != -1) return cursor.getString(index);
        return null;
    }

This and only this is the trick..
