How can I make this ContactsContract.Contact query faster with CommonDataKinds.Phone inner query?

I'm iterating through Contacts table and each iteration do iteration on Phone table so it takes appx. 4 seconds to do contact list for 243 contacts (without iterating phone numbers it loads instantly). I'm sure there is a way to make it faster.
Already made projections to fetch only needed columns, but haven't improved that much. Maybe I should improve SQLite query or iterate in some other manner:
Contact realmContact = new Contact();
Uri uri = Contacts.CONTENT_URI;
String[] projection = {
Contacts.LOOKUP_KEY,
Contacts.DISPLAY_NAME_PRIMARY,
Contacts.LAST_TIME_CONTACTED,
Contacts.HAS_PHONE_NUMBER
};
String selection = "((" + CommonDataKinds.Phone.DISPLAY_NAME_PRIMARY + " NOTNULL) AND ("
+ Contacts.HAS_PHONE_NUMBER + "=1) AND ("
+ CommonDataKinds.Phone.DISPLAY_NAME_PRIMARY + " != '' ))";
Cursor phones = getActivity()
.getContentResolver()
.query(uri, projection, selection, null, null);
while (phones.moveToNext()) {
String id = phones.getString(phones.getColumnIndex(Contacts.LOOKUP_KEY));
String name = phones.getString(phones.getColumnIndex(Contacts.DISPLAY_NAME_PRIMARY));
String lastTimeContacted = phones.getString(phones.getColumnIndex(Contacts.LAST_TIME_CONTACTED));
long data = Long.parseLong(lastTimeContacted);
String date = new SimpleDateFormat("dd/MM/yyyy | HH:mm").format(new Date(data));
if (Integer.parseInt(phones.getString(phones.getColumnIndex(Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = getActivity().getContentResolver().query(
CommonDataKinds.Phone.CONTENT_URI,
new String[]{CommonDataKinds.Phone.NUMBER},
CommonDataKinds.Phone.LOOKUP_KEY + " = ?",
new String[]{id}, null);
int iterationCounter = 0;
String phoneNumber = "";
while (pCur.moveToNext()) {
phoneNumber += iterationCounter == 0 ?
pCur.getString(pCur.getColumnIndex(CommonDataKinds.Phone.NUMBER))
: "," + pCur.getString(pCur.getColumnIndex(CommonDataKinds.Phone.NUMBER));
iterationCounter += 1;
}
realmContact.setNumber(phoneNumber);
Log.i("asd-number", phoneNumber);
pCur.close();
}
realmContact.setId(id);
realmContact.setName(name);
realmContact.setLastTimeContacted(
getActivity().getResources()
.getString(R.string.contacts_list_fragment_last_call)
+ date);
realmContact.setIsBeingSaved(true);
_realm.insertOrUpdate(realmContact);

As #pskink mentioned in the comments, you need to query over the Phone table.
To get the list of phones by contact, you can maintain a HashMap from contactId to List of phones.
Here's a little snippet that might help (you'd probably want to tweak the collection a bit to store the display-name only once per contact):
HashMap<Long, ArrayList<String>> phones = new HashMap<Long, ArrayList<String>>();
String[] projection = new String[] { Phone.CONTACT_ID, Phone.DISPLAY_NAME, Phone.NUMBER };
Cursor c = cr.query(Phone.CONTENT_URI, projection, null, null, null);
while (c != null && c.moveToNext()) {
long contactId = c.getLong(0);
ArrayList<String> list = phones.get(contactId);
if (list == null) {
ArrayList<String> list = new ArrayList<String>();
phones.put(contactId, list);
}
list.add(c.getString(1) + " " + c.getString(2));
}

context.getContentResolver().query(ContactsContract.Data.CONTENT_URI, null , null ,null, null);

Hi I am working in Android Contact search module.I am running below Query.
cur = context.getContentResolver().query(ContactsContract.Data.CONTENT_URI, null , null ,null, null);
from this query I am getting Result Multiple times.Is there any thing which I am doing wrong.I want DISTINCT Result Set.
please help me.

I think you mean you got duplicate record for some contacts. So you must add condition for your query
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '"
+ ("1") + "'";
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
cur = context.getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, projection, selection
+ " AND " + ContactsContract.Contacts.HAS_PHONE_NUMBER
+ "=1", null, sortOrder);// this query only return contacts which had phone number and not duplicated

Try this code will help you
public void getContact() {
Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
ContentResolver contect_resolver = getContentResolver();
int size = cur.getCount();
if (size > 0 && cur != null) {
for (int i = 0; i < size; i++) {
cur.moveToPosition(i);
String id = cur.getString(cur.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
String name = "";
Cursor phoneCur = contect_resolver.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
if (phoneCur.moveToFirst()) {
name = phoneCur.getString(phoneCur .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
if (!name.equalsIgnoreCase("")) {
String id1 = phoneCur.getString(phoneCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
Cursor emails = getContentResolver()
.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = " + Integer.parseInt(id1),
null, null);
emailAddress="";
if (emails!=null && emails.getCount() > 0) {
emails.moveToFirst();
emailAddress = emails
.getString(emails
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA));
}
emails.close();
contact.setEmail(emailAddress);
id1 = "";
mcontact_arraylist.add(contact);
}
phoneCur.close();
}
}
cur.close();
}
}

Each record should contain a portion of the data for a contact (eg each phone number or address is a separate row) each row has a mimetype associated with it that is used to determine the data stored in each column. So for an address, the "data1" column holds the street data and data4 might hold the state.

Android query phonenumber to obtain rawcontactID

I would like to query on phonenumber to obtain the rawcontactID.
The only thing I know of the contact is the given phonenumber, but for my function I need to have the rawcontactID. I got a working code but now I did use 2 seperate queries. What I would like to have is 1 query that can do both just to save some query time.
my code:
Uri uri = Uri.withAppendedPath(Phone.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
String[] columns = new String[]{Phone.CONTACT_ID, Phone.DISPLAY_NAME, Phone.NUMBER, Phone._ID };
Cursor cursor = contentResolver.query(uri, columns, null, null, null);
if(cursor!=null) {
int clenght = cursor.getCount();
while(cursor.moveToNext()){
//contactName = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
id = cursor.getString(cursor.getColumnIndex(Phone.CONTACT_ID));
}
cursor.close();
}
Cursor pCur = contentResolver.query(ContactsContract.Data.CONTENT_URI, new String[]{ContactsContract.Data.RAW_CONTACT_ID}, ContactsContract.Data.CONTACT_ID+" = "+ id, null, null);
if(pCur!=null) {
int clenght = pCur.getCount();
while(pCur.moveToNext()){
//contactName = cursor.getString(cursor.getColumnIndexOrThrow(PhoneLookup.DISPLAY_NAME));
id = pCur.getString(pCur.getColumnIndex(ContactsContract.Data.RAW_CONTACT_ID));
}
pCur.close();
}
thanks in advance
Edit:
My code above works fine, but I am still looking for increasing speed for large number of contacts. Therefore I will give a bounty if someone comes with a solution to combine my queries.

private String[] getRawContactIdFromNumber(String givenNumber){
List<String> rawIds = new ArrayList<String>();
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, new String[]{ContactsContract.CommonDataKinds.Phone.RAW_CONTACT_ID},ContactsContract.CommonDataKinds.Phone.NUMBER + "='"+ givenNumber +"'",null, ContactsContract.CommonDataKinds.Phone.NUMBER);
while (phones.moveToNext())
{
rawIds.add( phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.RAW_CONTACT_ID)));
Log.v("contacts","Given Number: " + givenNumber + "Raw ID: " +rawIds.get(rawIds.size() - 1));
}
phones.close();
String[] ret = new String[0];
return rawIds.toArray(ret);
}
Edited to only include the raw id in the cursor for efficiency. Also changed return type to array in case multiple contacts have the same number.

Please try
String phonenumber = "input your phone number";
Cursor pCur = getContentResolver().query(
ContactsContract.Data.CONTENT_URI,
new String[] { ContactsContract.Data.RAW_CONTACT_ID,
Phone.CONTACT_ID }, Phone.NUMBER + " = " + phonenumber,
null, null);
if (pCur != null) {
while (pCur.moveToNext()) {
String contactID = pCur.getString(pCur
.getColumnIndex(Phone.CONTACT_ID));
String Rowid = pCur.getString(pCur
.getColumnIndex(ContactsContract.Data.RAW_CONTACT_ID));
Log.e("RAW_CONTACT_ID", Rowid);
Log.e("CONTACT_ID", contactID);
}
pCur.close();
}
Now you can get Both CONTACT_ID & RAW_CONTACT_ID in single query.

Android: adding a birthday event to an android contact programmatically

I am trying to birthday information to a contact. I use lookupkey to identify my contacts (as it is safer than just relying on contactId). In order to be able to insert the Event into the database i need a raw_contact_id ... so i'm trying to get this id:
String where = ContactsContract.Data.LOOKUP_KEY + " = ? AND "
+ ContactsContract.Data.MIMETYPE + " = ?";
String[] params = new String[] { lookupKey,
ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE };
Cursor cursor = contentResolver.query(
ContactsContract.Data.CONTENT_URI, null, where, params, null);
if (cursor.moveToFirst()) {
birthdayRow = cursor.getInt(idIdx);
long rawContactId = cursor.getLong(cursor
.getColumnIndex(ContactsContract.Data.RAW_CONTACT_ID));
}
The problem is that if there is not birthday event set for a contact then this cursor i receive is empty ... and i don't know how to insert this event without a raw_contact_id. In order to insert the event i do the folowing:
values.put(ContactsContract.Data.RAW_CONTACT_ID, rawContactId);
values.put(ContactsContract.Data.MIMETYPE, Event.CONTENT_ITEM_TYPE);
values.put(ContactsContract.CommonDataKinds.Event.START_DATE,
birthdayStartDate);
values.put(ContactsContract.CommonDataKinds.Event.TYPE,
ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY);
values.put(ContactsContract.CommonDataKinds.Event.START_DATE,
context.getString(R.string.birthday_label));
if (birthdayRow >= 0) {
int result = contentResolver.update(
ContactsContract.Data.CONTENT_URI, values,
ContactsContract.Data._ID + " = " + birthdayRow, null);
Log.i("ContactList", "update result: " + result);
} else {
Uri result = contentResolver.insert(
ContactsContract.Data.CONTENT_URI, values);
Log.i("ContactList", "update result: " + result);
}
So please advice what shall i do, is there any way to add this event to the ContactData whitout a raw_contact id? Also i find strange the fact that for other ContactData like nickname i am doing the same thing and i dont get an empty cursor for the params
String[] params = new String[] { String.valueOf(lookupKey),
ContactsContract.CommonDataKinds.Nickname.CONTENT_ITEM_TYPE };
even if the contact has no nickname.

Use this to get the raw contact id before performing the insert.
long rawContactId = -1;
String[] projection = new String[]{ContactsContract.CommonDataKinds.Event.RAW_CONTACT_ID};
String selection = ContactsContract.CommonDataKinds.Event.CONTACT_ID + "=?";
String[] selectionArgs = new String[]{
String.valueOf(bdayContact.getId()) };
Cursor c = getContentResolver().query(ContactsContract.Data.CONTENT_URI, projection, selection, selectionArgs, null);
try {
if (c.moveToFirst()) {
rawContactId = c.getLong(0);
}
} finally {
c.close();
}

Android get a cursor only with contacts that have an email listed

Friends I want Contacts which have email and also sort in ascending order..
any one know how to get this list and sort..
Please help me and thanks in advance.
I am using this code.
MatrixCursor matCur = new MatrixCursor(new String[] { Contacts._ID,
Contacts.DISPLAY_NAME, "photo_id", "starred" });
Cursor cEmail = WP7Main.this.managedQuery(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
cEmail.moveToFirst();
if (cEmail.moveToFirst())
{
// String name =
// cursor.getString(cursor.getColumnIndexOrThrow(People.NAME));
String contactId = cEmail.getString(cEmail.getColumnIndex(ContactsContract.Contacts._ID));
Cursor emails = WP7Main.this.getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,ContactsContract.CommonDataKinds.Email.CONTACT_ID+ " = " + contactId, null, null);
String emailAddress = "";
while (emails.moveToNext())
{
// This would allow you get several email addresses
if (emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)) != null)
{
String[] columnValues = {
cEmail.getString(cEmail
.getColumnIndex("_id")),
cEmail.getString(cEmail
.getColumnIndex("display_name")),
cEmail.getString(cEmail
.getColumnIndex("photo_id")),
cEmail.getString(cEmail
.getColumnIndex("starred")) };
matCur.addRow(columnValues);
}
}
emails.close();
}

Try this:
/**
* #return A managed cursor of email contacts for the given activity.
*/
public static Cursor buildFilteredEmailCursor(Activity activity) {
final String my_sort_order = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
String my_selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '1'";
String[] eproj = new String[]{
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Email.DATA};
Uri uri = android.provider.ContactsContract.CommonDataKinds.Email.CONTENT_URI;
return activity.managedQuery(uri, eproj, my_selection, null, my_sort_order);
}

Use this query :
Cursor c = getContentResolver().query(Data.CONTENT_URI,
new String[]{Data.CONTACT_ID, Data.DISPLAY_NAME, Email.ADDRESS},
Data.MIMETYPE + "=?", new String[] {Email.CONTENT_TYPE}, Data.DISPLAY_NAME /* use Email.ADDRESS if you want to sort it using that*/);
