Question

I am creating a Bluetooth sync application with Outlook Express. All of the work has been done fantastically well but I have one small problem left. When I sync my contacts from Outlook to Android it merges the contacts with similar names. For instance, if I have two contacts called “Najhi” and “Najhi Ullah” then after syncing they will be merged in Android under one name “Najhi”. Is there any solution to separate all merged contacts programmatically?

I have found the solution on my own if anyone have the same problem, they can find this post.

  private void separate_merged_contacts(){
    Cursor cur1 = obj.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,new String[]{"_id"} , null, null,null);
    Cursor cur_raw;
    ArrayList<String> raw_contact_id = new ArrayList<String>();
    ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
    while (cur1.moveToNext()) {
        raw_contact_id.clear();
        ops.clear();
        for (int i = 0; i < cur1.getColumnCount(); i++) {
        cur_raw = obj.getContentResolver().query(ContactsContract.RawContacts.CONTENT_URI, new String[]{ContactsContract.RawContacts._ID}, ContactsContract.RawContacts.CONTACT_ID+"=?",new String[]{cur1.getString(cur1.getColumnIndex(ContactsContract.Contacts._ID))} , null);
        while(cur_raw.moveToNext()){
            for (int i = 0; i < cur_raw.getColumnCount(); i++) {
                raw_contact_id.add(cur_raw.getString(cur_raw.getColumnIndexOrThrow(ContactsContract.RawContacts._ID)));
            }
        }
        for(int i=0 ; i<raw_contact_id.size();i++){
            for(int j=0;j<raw_contact_id.size();j++)
                ops.add(ContentProviderOperation.newUpdate(ContactsContract.AggregationExceptions.CONTENT_URI)
                        .withValue(AggregationExceptions.TYPE,AggregationExceptions.TYPE_KEEP_SEPARATE)
                        .withValue(AggregationExceptions.RAW_CONTACT_ID1,Integer.parseInt(raw_contact_id.get(i)))
                        .withValue(AggregationExceptions.RAW_CONTACT_ID2,Integer.parseInt(raw_contact_id.get(j))).build());
                try {
                    obj.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
        }
    }
}
