Finally, I found how to update a contact, here is the code of the update method:

    public void update()
    {       
        int id = 1;
        String firstname = "Contact's first name";
        String lastname = "Last name";
        String number = "000 000 000";
        String photo_uri = "android.resource://com.my.package/drawable/default_photo";

        ArrayList ops = new ArrayList();

        // Name
        Builder builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
        builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?", new String[]{String.valueOf(id), ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE});
        builder.withValue(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME, lastname);
        builder.withValue(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME, firstname);
        ops.add(builder.build());

        // Number
        builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
        builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?"+ " AND " + ContactsContract.CommonDataKinds.Organization.TYPE + "=?", new String[]{String.valueOf(id), ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE, String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_HOME)});
        builder.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, number);
        ops.add(builder.build());


        // Picture
        try
        {
            Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), Uri.parse(photo_uri));
            ByteArrayOutputStream image = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG , 100, image);

            builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
            builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?", new String[]{String.valueOf(id), ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE});
            builder.withValue(ContactsContract.CommonDataKinds.Photo.PHOTO, image.toByteArray());
            ops.add(builder.build());
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }

        // Update
        try
        {
            getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }

The field id is the raw contact id returned when you insert a new contact into the database. Here is the code to get this id:

    ContentProviderResult[] res;
    try
    {
        res = KramerApplication.getInstance().getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
        if (res != null && res[0] != null)
        {
            String uri = res[0].uri.getPath().substring(14);
            r.setBook_id( new Integer(uri).intValue() );
        }
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
