android - How to only update contacts instead adding in sync adapter -


i have few numbers stored in apps database. wanted match numbers in contacts app , update contact mimetype. how whatsapp does. sync contacts , app icon comes in contact.

i have done sync part , if add new contact able show app icon in contact . requirement update existing contact.

this have tried update contact,

arraylist<contentprovideroperation> ops = new arraylist<contentprovideroperation>();          ops.add(contentprovideroperation.newinsert(addcallerissyncadapterparameter(data.content_uri, true))             .withvaluebackreference(data.raw_contact_id,id)             .withvalue(data.mimetype, mimetype)             .withvalue(data.data1, "username")             .withvalue(data.data2, "ite's me")             .build());          try {             context.getcontentresolver().applybatch(contactscontract.authority, ops);         }         catch (exception e) {             e.printstacktrace();         }

and rawcontactid fetching 

cursor cursor = context.getcontentresolver().query(data.content_uri, new string[] {data.raw_contact_id, data.display_name, data.mimetype, data.contact_id },               contactscontract.commondatakinds.phone.number + "= ?",                       new string[] {phonenumb}, null);

i not able add connections contact. doing wrong. can please me this.

thanks in advance.

the problem you're using withvaluebackreference reference raw contact id. try id of raw contact using parameter index previous operation in batch, i.e. if id=0, refer first operation, , if insert of new raw contact, use generated id raw contact id insert of contact data. want use withvalue here, since have raw contact id.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
