The short version of my question is: How do I access the phone numbers of contacts that were synced from 3rd party apps?
Here is the long version:
I can access the regular Android contacts pretty easily. The issue is when the only information in the contact list is synced with a 3rd party app like Facebook or LinkedIn. If I physically went and typed someone's phone number into the Google Contacts List, everything works fine.
However, if this phone number came from syncing my facebook account to my contact list, no phone number shows up, even though if I navigated to Google's pre-made contact list I can see a phone number is actually attached to the contact. Here is the code I use for getting the phone numbers.
public void populateNumberLists(View view)
{
LinearLayout ll = (LinearLayout) view;
TextView tv = (TextView) ll.findViewById(R.id.contactEntryText);
String str = (String) tv.getText();
Cursor cursor = getNumbers(str);
String[] fields = new String[] {
cursor.getColumnName(1).toString()
};
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.numberentry, cursor,
fields, new int[] {R.id.numberEntryText});
mNumberList.setAdapter(adapter);
}
private Cursor getNumbers(String str)
{
final Uri URIs = ContactsContract.Contacts.CONTENT_URI;
final String ID = ContactsContract.Contacts.LOOKUP_KEY;
String id = "";
ContentResolver cr = getContentResolver();
Cursor cu = cr.query(URIs, null, ContactsContract.Contacts.DISPLAY_NAME + " = '" + str + "'", null, null);
if (cu.moveToFirst()) {
id = cu.getString(cu.getColumnIndex(ID));
}
cu.close();
// Run query
Uri uri = Phone.CONTENT_URI;
String[] projection = new String[] {
Phone._ID,
Phone.NUMBER
};
String selection = Phone.LOOKUP_KEY + " = '" + id + "' and (" + Phone.TYPE + " = '" + Phone.TYPE_HOME+"' or " + Phone.TYPE + " = '" + Phone.TYPE_MOBILE+"' or " + Phone.TYPE + " = '" + Phone.TYPE_WORK+"' or " + Phone.TYPE + " = '" + Phone.TYPE_WORK_MOBILE+"')";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
return managedQuery(uri, projection, selection, selectionArgs, null);
}
Basically, the populateNumberLists function takes a clicked item from a list view, determines which contact from the list was clicked and calls the function getNumbers.
The getNumbers function takes actual name that was clicked, gets the lookup key for that name, then grabs all the phone numbers associated with that lookup key.
Oh, related to this, the only names displayed in the contact list are ones where ContactsContract.Contacts.HAS_PHONE_NUMBER equals 1. So I know that all the contacts that can be selected have a phone number attached.
Facebook is not included in the ContactPicker because Facebook forbid that.
This is a politically thing and won't be solved soon: Google wants Facebook to share data, Facebook uses Google but doesn't share..
You'll have to use the Facebook SDK for android to do this. Use an FQL query to get the phone number.

I am new to Android, currently I can retrieve contact list and image from Google contact. However, the contact list from my App does not provide suggestion for email within my company like the Google Gmail app.
Is it possible that I can retrieve these extra email addresses?
Below is the code to retrieve contact
public ArrayList<String> getNameEmailDetails() {
ArrayList<String> emlRecs = new ArrayList<String>();
HashSet<String> emlRecsHS = new HashSet<String>();
ContentResolver cr = 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);
if (cur.moveToFirst()) {
do {
// names comes in hand sometimes
String name = cur.getString(1);
String email = cur.getString(3);
String contact_id = cur.getString(4);
Bitmap profilePic = openPhoto(Long.parseLong(contact_id));
if (profilePic != null) {
profileList.add(new WordMatchAdapterWithIMG.profileWithIMG(email, profilePic));
}
} while (cur.moveToNext());
}
cur.close();
return emlRecs;
}
I would suggest you use the Google Contacts API.
The Google Contacts API allows client applications to view and update a user's contacts. Contacts are stored in the user's Google Account; most Google services have access to the contact list.
To retrieve a single contact, send an authorized GET request to the contact's selfLink URL:
https://www.google.com/m8/feeds/contacts/{userEmail}/full/{contactId}
Upon success, the server responds with an HTTP 200 OK status code and the requested contact entry.
public static ContactEntry retrieveContact(ContactsService myService) {
ContactEntry contact =
myService.getEntry(new URL("https://www.google.com/m8/feeds/contacts/default/full/contactId"),
ContactEntry.class);
// Do something with the contact.
return contact;
}

I've been working on a block of code to let the user search (character by character using an AutoCompleteTextView) contacts by name, email or phone number. I've worked out the below code:
// General contact data, so we have to get the DATA1 attribute and use MIMETYPE
// to figure out what it is. Usually we'd query, say, ContactsContract.CommonDataKinds.Email.CONTENT_URI
Uri uri = ContactsContract.Data.CONTENT_URI;
// Limit the query results to only the columns we need for faster operations.
// Using a projection also seems to make the query DISTINCT
String[] projection = new String[] {ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Data.DATA1,
ContactsContract.Data.MIMETYPE};
// Find contact records with an email address or phone number
// Search the name and data1 field (which may contain an email or phone number)
// for user-entered search phrase
String filter = "(" + ContactsContract.Data.MIMETYPE + "=? OR " + ContactsContract.Data.MIMETYPE + "=?)"
+ " AND (" + ContactsContract.Data.DATA1 + " LIKE ? OR " + ContactsContract.Data.DISPLAY_NAME + " LIKE ?)";
String wildcardedConstraint = "%" + constraintString + "%";
String[] filterParams = new String[]{ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE, wildcardedConstraint, wildcardedConstraint};
// Sort contacts with the most recently contacted ones first. That's often 0 (unset)
// so do a sub-sort by last updated date, most recent contacts first
String orderBy = ContactsContract.Contacts.LAST_TIME_CONTACTED + " DESC, " + ContactsContract.Contacts.CONTACT_LAST_UPDATED_TIMESTAMP + " DESC";
Cursor cursor = getContext().getContentResolver().query(uri, projection, filter, filterParams, orderBy);
if (cursor != null) {
while (cursor.moveToNext()) {
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
String data1 = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DATA1));
String mimetype = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE));
String number = null;
String email = null;
if (mimetype.equals(ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE)) {
email = data1;
} else if (mimetype.equals(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE)) {
number = data1;
}
items.add(new Person(name, number, email));
Log.e("temp", name + " " + data1 + " " + mimetype);
}
cursor.close();
}
There is a problem with the phone number search, however. In contacts, phone numbers are in many different formats:
+101234567890
(123) 456-7890
1234567890
123-456-7890
And so on.
How can I adapt my Contacts query filter so the user's input will find phone numbers in any format--preferably without making the entire query extremely slow?
Some solutions I've found rely on editing table data to standardize the phone numbers, which isn't an option with contacts. Maybe that normalized number field would work... if I could find a way to easily build it into this query on the Contacts Data table. I know I could do extra phone number searches for each record, or use Java to make the checks, but I think that would make it very slow. Perhaps a regexp SQL operator in the query--but I don't know how I could make it work for the user's character-by-character search where they may have only entered part of the phone number.
Any ideas?
You can do this with Android's built-in SQLite function PHONE_NUMBERS_EQUAL, which compares two numbers and will return 1 if they're identical enough for caller ID purposes.
You simply need to change your filter as follows:
String filter = "(" + ContactsContract.Data.MIMETYPE + "=? OR "
+ ContactsContract.Data.MIMETYPE + "=?) AND "
+ "(PHONE_NUMBERS_EQUAL(" + ContactsContract.Data.DATA1 + ", ?, 0) OR "
+ ContactsContract.Data.DATA1 + " LIKE ? OR "
+ ContactsContract.Data.DISPLAY_NAME + " LIKE ?)";
And add another wildcardedConstraint to your filterParams:
String[] filterParams = new String[] { ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,
ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,
wildcardedConstraint,
wildcardedConstraint,
wildcardedConstraint };
The final INTEGER parameter in the PHONE_NUMBERS_EQUAL function indicates whether to use strict number comparation; 1 meaning do use strict, 0 meaning non-strict. Apparently this is a system-wide setting that can be retrieved from the system Resources, but I am uncertain as to what factors dictate how this is determined for a particular environment. The example above just uses non-strict comparation. However, if it is a concern, the actual resource value can be obtained like so:
private static final String STRICT_COMPARE = "config_use_strict_phone_number_comparation";
...
int strictResId = Resources.getSystem().getIdentifier(STRICT_COMPARE, "bool", "android");
boolean useStrict = Resources.getSystem().getBoolean(strictResId);
I'm attempting to retrieve both email and phone via a single cursor described below. I'm using the Email.CONTENT_URI, hence I don't retrieve the phone number, so my phoneColumn is returning email. I tried using Phone.CONTENT_URI but it only returns a smaller subset of contacts (possibly because it only fetches ones that have phone numbers). Is there a way to get both email and phone with a specific Uri or how can I do it with two cursors?
Cursor cursor = context.getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
projection, null, null, order);
int idColumn = cursor.getColumnIndex(ContactsContract.Data._ID);
int nameColumn = cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME);
int emailColumn = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
int phoneColumn = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA);
where projection is:
String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Data.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Email.DATA,
ContactsContract.CommonDataKinds.Phone.DATA, }
Please have a look here. You should find all the necessary examples for such kind of querying.
For an example, you can fetch all information of a contactId in this way:
Cursor data = context.getContentResolver().query(
Data.CONTENT_URI, new String[] { Data._ID,Data.MIMETYPE,
Email.ADDRESS, Photo.PHOTO},Data.CONTACT_ID
+ "=?" + " AND " + "(" + Data.MIMETYPE + "='"
+ Photo.CONTENT_ITEM_TYPE + "' OR " + Data.MIMETYPE
+ "='" + Email.CONTENT_ITEM_TYPE +"')",
new String[] {String.valueOf(contactId)}, null);
You can fetch info for all contacts in this way and then probably sort it according to your criteria. You can build queries like this based on your need.
I have created this library to solve all your queries. It will only save contacts with at least one email or phone number. Also it will remove duplicates from emails and phone numbers from same contacts (created by 3rd party apps like whatsapp).
Please have a look at it.

I have a string content//com.android.contacts/contacts/contacts/2 ie aft the user has selected a particular number.
From this string, how do i get the phone number of this particular contact?
I am new to android environment, so my question might seem a bit primitive.
Cursor c = (Cursor)mAdapter.getItem(a.keyAt(i));
Long id = c.getLong(c.getColumnIndex(ContactsContract.Contacts._ID));
contacts.add(ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id));
chosenContacts = sb.toString();
chosenContacts is my string and that contains content//com.android.contacts/contacts/contacts/2
You need a second request. You can use the id of your snippet for it:
Cursor phoneNoCursor = contentResolver.query(
Data.CONTENT_URI,
new String[] {Phone.NUMBER, Phone.TYPE, Phone.LABEL},
Data.MIMETYPE + " = ? AND " + Data.CONTACT_ID + " = ? ",
new String[] {String.valueOf(Phone.CONTENT_ITEM_TYPE, id)},
null);
For the list of possible types see the description of the Phone class. But maybe the number itself and its label are enough anyway.
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
