ContactsContract select records by phone number

I can select all contacts using the query below
cr = mActivity.getContentResolver();
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " > 0";
String orderBy = ContactsContract.Contacts.DISPLAY_NAME + " ASC ";
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, selection, null, orderBy);
However, I have a phone number list and I want to create this query like
String selection = ContactsContract.Contacts.PhoneNumber_or_something_else in (MyPhoneNumberArray)
Is that possible to do this?
A worst-case scenario, I can remove the related item using do while after I create my cursor, but, as far as I know, I cannot remove any record from the cursor.

The Contacts DB is organized in three main tables:
Contacts - each entry represents one contact, and groups together one or more RawContacts
RawContacts - each entry represents data about a contact that was synced in by some SyncAdapter (e.g. Whatsapp, Google, Facebook, Viber), this groups multiple Data entries
Data - The actual data about a contact, emails, phones, etc. each line is a single piece of data that belongs to a single RawContact
All phone numbers in the Contacts DB are in the Data table, so that's what you need to query, you can get the list of CONTACT_IDs from that query and use it to get general info about contacts if you need.
String[] phonesList = new String[] { "+121212345" }; // will work better if all phones in this list are in e164 format
String[] projection = { Phone.CONTACT_ID, Phone.DISPLAY_NAME, Phone.NUMBER, Phone.NORMALIZED_NUMBER };
String selection = Phone.NUMBER + " IN ('" + TextUtils.join("','", phonesList) + "') OR " +
Phone.NORMALIZED_NUMBER + " IN ('" + TextUtils.join("','", phonesList) + "')";
Cursor cur = cr.query(Phone.CONTENT_URI, projection, selection, null, null);
while (cur != null && cur.moveToNext()) {
long id = cur.getLong(0);
String name = cur.getString(1);
String phone = cur.getString(2);
Log.d(TAG, "got " + id + ", " + name + ", " + phone;
}

How to receive local contacts with emai addresses using the content resolver

I am developing an Android app and want to receive my local contacts. To be exact I want to display all contacts which have an email address. My current approach looks like this
import android.provider.ContactsContract.CommonDataKinds.Email;
import android.provider.ContactsContract.Contacts;
import android.provider.ContactsContract.Data;
private static final String[] CONTACT_PROJECTION = new String[] {
Email.CONTACT_ID,
Contacts.DISPLAY_NAME_PRIMARY,
Email.ADDRESS,
};
Cursor data = mResolver.query(Data.CONTENT_URI,
CONTACT_PROJECTION,
Data.MIMETYPE + "='" + Email.CONTENT_ITEM_TYPE + "'",
null, Contacts.DISPLAY_NAME_PRIMARY + " ASC");
The problem using this query is, that the result contains rows that doesn't match a contact in my local address book. Probably I used those email addresses before but didn't saved it to my address book.
I have already tried another approach where I made a query on Contacts.CONTENT_URI with Contacts._ID. This id is used as a foreign key to match the contacts in a second query against their emails. The solution was a nested cursor and the runtime was really slow. For a hundred contacts the query took more than two seconds to match. This is a reason for using the async CursorLoader but I want to avoid it if possible.
Any suggestions? Thanks in advance
#Edit 1:
Unfortunately both solutions don't archive the desired improvement.
For example, when I write a new email to a previous unknown address with my gmail app afterwards the address shows up in both querys with an contact id but not in my normal address book. This kind of "contacts" flood my query.
Could it be related to the value of ContactsContract.CommonDataKinds.Email.TYPE?
#Edit 2:
I found an interesting flag Contacts.IN_VISIBLE_GROUP + "=1". It seems to filter the unwanted addresses.
Has somebody any experience with it? I don't want to filter to much.

This is what I am using in my app:
public void readContacts(){
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
System.out.println("name : " + name + ", ID : " + id);
// get the phone number
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
String phone = pCur.getString(
pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
System.out.println("phone" + phone);
}
pCur.close();
// get email and type
Cursor emailCur = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
while (emailCur.moveToNext()) {
// This would allow you get several email addresses
// if the email addresses were stored in an array
String email = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
String emailType = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
System.out.println("Email " + email + " Email Type : " + emailType);
}
emailCur.close();
}
}
}
}

I have attached one of the functions used in my project. Point of intrest would be selection and selection args.
Snippet
selection = ContactsContract.CommonDataKinds.Email.DATA + " != ?";
selectionArgs = new String[]{""};
This says selection is based on email data and it should not be null.
Similarly you can add any of the selection params as per your need.
Entire Function
public Cursor getInitCursorLoader() {
String[] PROJECTION = null;
String selection = null;
String[] selectionArgs = new String[0];
String order = null;
Uri contentURI = null;
switch (mFriendType) {
case EMAIL:
PROJECTION = new String[]{
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts._ID,
ContactsContract.Contacts.PHOTO_ID,
ContactsContract.CommonDataKinds.Email.TIMES_CONTACTED,
ContactsContract.CommonDataKinds.Email.DATA};
selection = ContactsContract.CommonDataKinds.Email.DATA + " != ?";
selectionArgs = new String[]{""};
contentURI = ContactsContract.CommonDataKinds.Email.CONTENT_URI;
order = ContactsContract.CommonDataKinds.Email.TIMES_CONTACTED + " DESC";
break;
case SMS:
PROJECTION = new String[]{
ContactsContract.Contacts._ID,
ContactsContract.Contacts.PHOTO_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.TIMES_CONTACTED,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.TYPE};
selection = ContactsContract.CommonDataKinds.Phone.TYPE + " = ?";
selectionArgs = new String[]{String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE)};
contentURI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
order = ContactsContract.CommonDataKinds.Phone.TIMES_CONTACTED + " DESC";
break;
}
return mContext.getContentResolver().query(contentURI, PROJECTION, selection, selectionArgs, order);
}

How to get Contact ID, Email, Phone number in one SQLite query ? Contacts Android Optimization

I want to fetch All Contacts atleast with one phone Number, also I want all Phone Numbers and All emails for every Contact.
Current code :
// To get All Contacts having atleast one phone number.
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " > ?";
String[] selectionArgs = new String[] {"0"};
Cursor cu = applicationContext.getContentResolver().query(uri,
null, selection, selectionArgs, null);
// For getting All Phone Numbers and Emails further queries :
while(cu.moveToNext()){
String id = cu.getString(cu.getColumnIndex(ContactsContract.Contacts._ID));
// To get Phone Numbers of Contact
Cursor pCur = context.getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?",
new String[]{id}, null);
// To get Email ids of Contact
Cursor emailCur = context.getContentResolver().query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
// Iterate through these cursors to get Phone numbers and Emails
}
If there are more than 1000 contacts in my Device, it is taking too much time. How can I get All Data in single query, rather than doing two additional queries for each contact?
Or is there any other way to optimize?
Thank you in Advance.

ICS: When you query from Data.CONTENT_URI you have all the rows from the associated Contact already joined - i.e. this would work:
ContentResolver resolver = getContentResolver();
Cursor c = resolver.query(
Data.CONTENT_URI,
null,
Data.HAS_PHONE_NUMBER + "!=0 AND (" + Data.MIMETYPE + "=? OR " + Data.MIMETYPE + "=?)",
new String[]{Email.CONTENT_ITEM_TYPE, Phone.CONTENT_ITEM_TYPE},
Data.CONTACT_ID);
while (c.moveToNext()) {
long id = c.getLong(c.getColumnIndex(Data.CONTACT_ID));
String name = c.getString(c.getColumnIndex(Data.DISPLAY_NAME));
String data1 = c.getString(c.getColumnIndex(Data.DATA1));
System.out.println(id + ", name=" + name + ", data1=" + data1);
}
If you are targeting 2.3 you need to account for the fact that HAS_PHONE_NUMBER is not available through the joins used when querying Data.
Fun.
This could, for instance, be solved either by skipping your requirement that the contact must have a phone number and instead settle for "any contact with at least a phone number or an e-mail address":
Cursor c = resolver.query(
Data.CONTENT_URI,
null,
Data.MIMETYPE + "=? OR " + Data.MIMETYPE + "=?",
new String[]{Email.CONTENT_ITEM_TYPE, Phone.CONTENT_ITEM_TYPE},
Data.CONTACT_ID);
If that is not an option you can always go for a horribly hacky sub-select:
Cursor c = resolver.query(
Data.CONTENT_URI,
null,
"(" + Data.MIMETYPE + "=? OR " + Data.MIMETYPE + "=?) AND " +
Data.CONTACT_ID + " IN (SELECT " + Contacts._ID + " FROM contacts WHERE " + Contacts.HAS_PHONE_NUMBER + "!=0)",
new String[]{Email.CONTENT_ITEM_TYPE, Phone.CONTENT_ITEM_TYPE}, Data.CONTACT_ID);
or solve it by using two Cursors:
Cursor contacts = resolver.query(Contacts.CONTENT_URI,
null, Contacts.HAS_PHONE_NUMBER + " != 0", null, Contacts._ID + " ASC");
Cursor data = resolver.query(Data.CONTENT_URI, null,
Data.MIMETYPE + "=? OR " + Data.MIMETYPE + "=?",
new String[]{Email.CONTENT_ITEM_TYPE, Phone.CONTENT_ITEM_TYPE},
Data.CONTACT_ID + " ASC");
int idIndex = contacts.getColumnIndexOrThrow(Contacts._ID);
int nameIndex = contacts.getColumnIndexOrThrow(Contacts.DISPLAY_NAME);
int cidIndex = data.getColumnIndexOrThrow(Data.CONTACT_ID);
int data1Index = data.getColumnIndexOrThrow(Data.DATA1);
boolean hasData = data.moveToNext();
while (contacts.moveToNext()) {
long id = contacts.getLong(idIndex);
System.out.println("Contact(" + id + "): " + contacts.getString(nameIndex));
if (hasData) {
long cid = data.getLong(cidIndex);
while (cid <= id && hasData) {
if (cid == id) {
System.out.println("\t(" + cid + "/" + id + ").data1:" +
data.getString(data1Index));
}
hasData = data.moveToNext();
if (hasData) {
cid = data.getLong(cidIndex);
}
}
}
}

I went through the exact same problem. Since then I build my own solution which is inspired from this post yet a bit different. Now I'd like to share it as my first StackOverFlow answer :-)
Its quite similar to the double cursor approach suggested by Jens. The idea is to
1- fetch relevant contact from the Contacts table
2- fetch relevant Contacts information (mail, phone, ...)
3- combine these results
The "relevant" is up to you of course but the important point is the performance !
Besides, I'm sure other solutions using well suited SQL query might as well do the job but here I only want to use the Android ContentProvider
Here is the code :
Some constants
public static String CONTACT_ID_URI = ContactsContract.Contacts._ID;
public static String DATA_CONTACT_ID_URI = ContactsContract.Data.CONTACT_ID;
public static String MIMETYPE_URI = ContactsContract.Data.MIMETYPE;
public static String EMAIL_URI = ContactsContract.CommonDataKinds.Email.DATA;
public static String PHONE_URI = ContactsContract.CommonDataKinds.Phone.DATA;
public static String NAME_URI = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) ? ContactsContract.Data.DISPLAY_NAME_PRIMARY : ContactsContract.Data.DISPLAY_NAME;
public static String PICTURE_URI = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) ? ContactsContract.Contacts.PHOTO_THUMBNAIL_URI : ContactsContract.Contacts.PHOTO_ID;
public static String MAIL_TYPE = ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE;
public static String PHONE_TYPE = ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE;
1 Contact
Here I require that the Contacts must have DISPLAY_NAME free of "#" and that their informations match a given string (these requirement can of course be modified). The result of the following method is the first cursor :
public Cursor getContactCursor(String stringQuery, String sortOrder) {
Logger.i(TAG, "+++++++++++++++++++++++++++++++++++++++++++++++++++");
Logger.e(TAG, "ContactCursor search has started...");
Long t0 = System.currentTimeMillis();
Uri CONTENT_URI;
if (stringQuery == null)
CONTENT_URI = ContactsContract.Contacts.CONTENT_URI;
else
CONTENT_URI = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_FILTER_URI, Uri.encode(stringQuery));
String[] PROJECTION = new String[]{
CONTACT_ID_URI,
NAME_URI,
PICTURE_URI
};
String SELECTION = NAME_URI + " NOT LIKE ?";
String[] SELECTION_ARGS = new String[]{"%" + "#" + "%"};
Cursor cursor = sContext.getContentResolver().query(CONTENT_URI, PROJECTION, SELECTION, SELECTION_ARGS, sortOrder);
Long t1 = System.currentTimeMillis();
Logger.e(TAG, "ContactCursor finished in " + (t1 - t0) / 1000 + " secs");
Logger.e(TAG, "ContactCursor found " + cursor.getCount() + " contacts");
Logger.i(TAG, "+++++++++++++++++++++++++++++++++++++++++++++++++++");
return cursor;
}
This query is quite performant as you'll see !
2 Contact Details
Now let's fetch Contact informations. At this point, I dont make any link between the already fetched Contact and the retrieved information : I just fetch all informations form the Data table... Yet, to avoid useless info I still require DISPLAY_NAMES free of "#" and since I'm interested in email and phone I require that the data MIMETYPE to be either MAIL_TYPE or PHONE_TYPE (see Constants). Here is the code :
public Cursor getContactDetailsCursor() {
Logger.i(TAG, "+++++++++++++++++++++++++++++++++++++++++++++++++++");
Logger.e(TAG, "ContactDetailsCursor search has started...");
Long t0 = System.currentTimeMillis();
String[] PROJECTION = new String[]{
DATA_CONTACT_ID_URI,
MIMETYPE_URI,
EMAIL_URI,
PHONE_URI
};
String SELECTION = ContactManager.NAME_URI + " NOT LIKE ?" + " AND " + "(" + MIMETYPE_URI + "=? " + " OR " + MIMETYPE_URI + "=? " + ")";
String[] SELECTION_ARGS = new String[]{"%" + "#" + "%", ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE};
Cursor cursor = sContext.getContentResolver().query(
ContactsContract.Data.CONTENT_URI,
PROJECTION,
SELECTION,
SELECTION_ARGS,
null);
Long t1 = System.currentTimeMillis();
Logger.e(TAG, "ContactDetailsCursor finished in " + (t1 - t0) / 1000 + " secs");
Logger.e(TAG, "ContactDetailsCursor found " + cursor.getCount() + " contacts");
Logger.i(TAG, "+++++++++++++++++++++++++++++++++++++++++++++++++++");
return cursor;
}
Once again you will see that this query is quite fast...
3 Combining
Now let's combine both Contact and their respective informations. The idea is to use HashMap(Key, String) where Key is the Contact id and String is whatever you like (name, email, ...).
First, I run through the Contact cursor (which is alphabetically ordered) and store names and picture uri in two different HashMap. Note also that I store all Contact id's in a List in the very same order that Contacts appear in the cursor. Lets call this list contactListId
I do the same for the Contact informations (mail and email). But now I take care of the correlation between the two cursor : if the CONTACT_ID of an email or phone does not appear in contactListId it is put aside. I check also if the email has already been encountered. Notice that this further selection can introduce asymmetries between the Name/Picture content and the Email/Phone HashMap content but don't worry.
Eventually, I run over the contactListId list and build a list of Contact object taking care of the fact that : a contact must have information (keySet condition) and that the contact must have at least a mail or an email (the case where mail == null && phone == null may appear if the contact is a Skype contact for instance).
And here is the code :
public List<Contact> getDetailedContactList(String queryString) {
/**
* First we fetch the contacts name and picture uri in alphabetical order for
* display purpose and store these data in HashMap.
*/
Cursor contactCursor = getContactCursor(queryString, NAME_URI);
List<Integer> contactIds = new ArrayList<>();
if (contactCursor.moveToFirst()) {
do {
contactIds.add(contactCursor.getInt(contactCursor.getColumnIndex(CONTACT_ID_URI)));
} while (contactCursor.moveToNext());
}
HashMap<Integer, String> nameMap = new HashMap<>();
HashMap<Integer, String> pictureMap = new HashMap<>();
int idIdx = contactCursor.getColumnIndex(CONTACT_ID_URI);
int nameIdx = contactCursor.getColumnIndex(NAME_URI);
int pictureIdx = contactCursor.getColumnIndex(PICTURE_URI);
if (contactCursor.moveToFirst()) {
do {
nameMap.put(contactCursor.getInt(idIdx), contactCursor.getString(nameIdx));
pictureMap.put(contactCursor.getInt(idIdx), contactCursor.getString(pictureIdx));
} while (contactCursor.moveToNext());
}
/**
* Then we get the remaining contact information. Here email and phone
*/
Cursor detailsCursor = getContactDetailsCursor();
HashMap<Integer, String> emailMap = new HashMap<>();
HashMap<Integer, String> phoneMap = new HashMap<>();
idIdx = detailsCursor.getColumnIndex(DATA_CONTACT_ID_URI);
int mimeIdx = detailsCursor.getColumnIndex(MIMETYPE_URI);
int mailIdx = detailsCursor.getColumnIndex(EMAIL_URI);
int phoneIdx = detailsCursor.getColumnIndex(PHONE_URI);
String mailString;
String phoneString;
if (detailsCursor.moveToFirst()) {
do {
/**
* We forget all details which are not correlated with the contact list
*/
if (!contactIds.contains(detailsCursor.getInt(idIdx))) {
continue;
}
if(detailsCursor.getString(mimeIdx).equals(MAIL_TYPE)){
mailString = detailsCursor.getString(mailIdx);
/**
* We remove all double contact having the same email address
*/
if(!emailMap.containsValue(mailString.toLowerCase()))
emailMap.put(detailsCursor.getInt(idIdx), mailString.toLowerCase());
} else {
phoneString = detailsCursor.getString(phoneIdx);
phoneMap.put(detailsCursor.getInt(idIdx), phoneString);
}
} while (detailsCursor.moveToNext());
}
contactCursor.close();
detailsCursor.close();
/**
* Finally the contact list is build up
*/
List<Contact> contacts = new ArrayList<>();
Set<Integer> detailsKeySet = emailMap.keySet();
for (Integer key : contactIds) {
if(!detailsKeySet.contains(key) || (emailMap.get(key) == null && phoneMap.get(key) == null))
continue;
contacts.add(new Contact(String.valueOf(key), pictureMap.get(key), nameMap.get(key), emailMap.get(key), phoneMap.get(key)));
}
return contacts;
}
The Contact object definition is up to you.
Hope this will help and thanks for the previous post.
Correction/Improvement
I forgot to check the phone key set : it should rather looks like
!mailKeySet.contains(key)
replaced by
(!mailKeySet.contains(key) && !phoneKeySet.contains(key))
with the phone keySet
Set<Integer> phoneKeySet = phoneMap.keySet();
I why not add an empty contact cursor check like :
if(contactCursor.getCount() == 0){
contactCursor.close();
return new ArrayList<>();
}
right after the getContactCursor call

Problem in ContactsContract API android

i have an HTC legend.In its phone contacts it shows 4-5 contacts.But when i query it in my application it shows nearly 45 contacts.I think its gmail contacts.
String[] Projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.PHOTO_ID,
ContactsContract.Contacts.HAS_PHONE_NUMBER,
ContactsContract.Contacts.STARRED};
Cursor cursor = managedQuery(ContactsContract.Contacts.CONTENT_URI, Projection, null, null, null);
I am getting all the details with photo as well in a listview. Now i need to get particular contact details like all his phone numbers,emails,photo etc.For this i am writing this query
final String[] projection = new String[] {
ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
ContactsContract.CommonDataKinds.Phone.TYPE,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.IS_PRIMARY,
};
final Cursor phone = managedQuery(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?",
new String[]{contactId},
null);
> if(phone.moveToFirst()) {
> final int contactNumberColumnIndex =
> phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
> final int contactTypeColumnIndex =
> phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE);
i am getting all the details of the phone contact but not all other contacts.
i have read that all these details are stored in shared table(ContactsContract.Data.CONTENT_URI), but i am not getting exactly what to do go get this done.
Can someone help me figure out how to do this.
Thanks

You can do something like:
getContentResolver().query(
RawContactsEntity.CONTENT_URI,
// projection
new String[] {
BaseColumns._ID,
RawContactsEntity.MIMETYPE,
// DATA columns are interpreted according to MIMETYPE
// Project only union of data columns needed
RawContactsEntity.DATA1,
RawContactsEntity.DATA2,
RawContactsEntity.DATA3,
RawContactsEntity.DATA4,
RawContactsEntity.DATA7,
RawContactsEntity.DATA9,
RawContactsEntity.DATA10,
},
// selection
RawContactsEntity.DELETED + "<>1 AND " +
RawContactsEntity.MIMETYPE + " IN ('" +
StructuredName.CONTENT_ITEM_TYPE + "','" +
Email.CONTENT_ITEM_TYPE + "','" +
Phone.CONTENT_ITEM_TYPE + "','" +
StructuredPostal.CONTENT_ITEM_TYPE + "','" +
Organization.CONTENT_ITEM_TYPE + "')",
// selection params
null,
// sorting
null);
Next iterate through cursor, and first read MIME type:
final String mimeType = cursor.getString(cursor.getColumnIndex(
RawContactsEntity.MIMETYPE));
And depends on MIME type read corresponding data kind:
if (StructuredName.CONTENT_ITEM_TYPE.equals(mimeType)) {
readNameData(cursor);
} else if (Email.CONTENT_ITEM_TYPE.equals(mimeType)) {
addEmailData(cursor);
}
and so on.

Android get a cursor only with contacts that have an email listed >android 2.0

i have the following code to get contacts from content provider
String[] columns = new String[] {
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts._ID,
ContactsContract.Contacts.PHOTO_ID };
Cursor cursor = managedQuery(ContactsContract.Contacts.CONTENT_URI,
columns, null, null, null);
and i use this one to get the emails for a specific contact by their id:
Cursor emails = getContentResolver().query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = " + contact.getContactId(), null, null);
my current implementation passes every row in the cursor and aquires its emails and stores them in an arrayList of java objects.
what i was wondering if it was possible to do is just query the content provider and return a cursor of just contacts with ids/name etc that have an email address listed.
this way has a long waiting period for getting the contact list. i am using this list for a list adapter. if i can get only the contacts that have an email i can use a cursor adapter in my list.
Is something like this possible? how can i speed up the process?

#CapDroid
Fixed working code from DArkO's post:
ContentResolver cr = context.getContentResolver();
String[] PROJECTION = new String[] { ContactsContract.RawContacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.PHOTO_ID,
ContactsContract.CommonDataKinds.Email.DATA,
ContactsContract.CommonDataKinds.Photo.CONTACT_ID };
String order = "CASE WHEN "
+ ContactsContract.Contacts.DISPLAY_NAME
+ " NOT LIKE '%#%' THEN 1 ELSE 2 END, "
+ ContactsContract.Contacts.DISPLAY_NAME
+ ", "
+ ContactsContract.CommonDataKinds.Email.DATA
+ " COLLATE NOCASE";
String filter = ContactsContract.CommonDataKinds.Email.DATA + " NOT LIKE ''";
Cursor cur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, PROJECTION, filter, null, order);
Your cursor will have essential IDs as well as names and email addresses. The performance of this code is great because it requests few columns only.

I solved this one, here is how its done:
UPDATE
String[] PROJECTION = new String[] { ContactsContract.RawContacts._ID,
ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.PHOTO_ID,
Email.DATA, ContactsContract.CommonDataKinds.Photo.CONTACT_ID };
String order = " CASE WHEN " + ContactsContract.Contacts.DISPLAY_NAME
+ " NOT LIKE '%#%' THEN 1" + " ELSE 2 END, "
+ ContactsContract.Contacts.DISPLAY_NAME + " COLLATE NOCASE";
String filter = Email.DATA + " NOT LIKE '' ) GROUP BY ( " + Email.DATA;
return mContent.query(Email.CONTENT_URI,
PROJECTION, filter, null, order);
