How to get all contacts first name, last name, email, phone number, etc without duplicates

I am trying to get details of all the contacts available in phone contacts using below code. But facing small issue of duplicate values.
EDITED
ACTUAL CODE STARTS :-
private String refreshData() {
String emaildata = "";
try {
ContentResolver cr = getBaseContext().getContentResolver();
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP
+ " = '" + ("1") + "'";
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
Cursor cur = cr
.query(ContactsContract.Contacts.CONTENT_URI,
null,
selection
+ " AND "
+ ContactsContract.Contacts.HAS_PHONE_NUMBER
+ "=1", null, sortOrder);
if (cur.getCount() > 0) {
Log.i("Content provider", "Reading contact emails");
while (cur.moveToNext()) {
mContactSet.add(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID)));
}
} else {
emaildata += "Data not found.";
}
cur.close();
Log.i(TAG, "Total contacts = " + mContactSet.size());
Iterator<String> iterator = mContactSet.iterator();
while (iterator.hasNext()) {
String contactId = iterator.next();
Log.i(TAG, "ID ==> " + contactId);
// Create query to use CommonDataKinds classes to fetch
// emails
Cursor emails = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null, ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = " + contactId, null, null);
// Name
String whereName = ContactsContract.Data.MIMETYPE
+ " = ? AND "
+ ContactsContract.CommonDataKinds.StructuredName.CONTACT_ID
+ " = ?";
String[] whereNameParams = new String[] {
ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE,
contactId };
Cursor nameCur = cr
.query(ContactsContract.Data.CONTENT_URI,
null,
whereName,
whereNameParams,
ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME);
while (nameCur.moveToNext()) {
String given = nameCur
.getString(nameCur
.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME));
String family = nameCur
.getString(nameCur
.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME));
String display = nameCur
.getString(nameCur
.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME));
Log.i(TAG, "First Name ==> " + given);
Log.i(TAG, "Last Name ==> " + family);
Log.i(TAG, "Display ==> " + display);
}
nameCur.close();
}
} catch (Exception e) {
emaildata += "Exception : " + e + "";
}
return emaildata;
}
Modified the query and get some better results but still the issue is same for some of the contacts and getting repeat values.
UPDATE :- I have used HashSet to get unique contact id and which I successfully get as well, but when I am getting the names from contact id I am getting the same value for 2-3 times for some of the contacts. I am very much confused that how this is possible that same contact is stored 2-3 times with same id?
DO I NEED TO USE HASHSET FOR FIRST NAME, LAST NAME, PHONE NUMBER, EMAIL, ETC? IS THERE ANY OTHER WAY?

This is the complete solution

How to use?
ArrayList<HashMap<String, Object>> contactList = getContacts();
System.out.println("Contact List : " +contactList);
Output:

NOTE:
You will get phone and email semicolon(;) separated if its more than one.

get contact event details in android

I need to fetch the all events of all contacts in my android application.
Can anyone help me on this?
what I need to place the Uri for the below..
Cursor events = getContentResolver().query(xxxx,null,ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null);

Try this method, it should work. Do the Log.d(tag, "Output here"); to test your output, but it should work. It does here.
public void getEvent(String contactId)
{
final String[] projection = new String[] {
Event.CONTACT_ID,
Event.START_DATE,
//Event.TYPE,
Event.LABEL
};
final String filter = Data.MIMETYPE + " = ? AND " + Data.CONTACT_ID + " = ? ";
final String parameters[] = {Event.CONTENT_ITEM_TYPE, contactId};
Cursor cursor = context.getContentResolver().query(Data.CONTENT_URI,
projection,
filter,
parameters,
null);
if(cursor.moveToFirst())
{
for(cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext())
{
final String contact_id = cursor.getString(cursor.getColumnIndex(Event.CONTACT_ID));
final String startDate = cursor.getString(cursor.getColumnIndex(Event.START_DATE));
//final String type = cursor.getString(cursor.getColumnIndex(Event.TYPE));
final String label = cursor.getString(cursor.getColumnIndex(Event.LABEL));
}
}
}

How load all the contacts with minimum time in Android

In my project getting contacts is taking a long time to load.
What are ways to reduce the time of getting contacts
Assume there are 1000 contacts in my phone.
Right now it is taking more than 2 minutes to load all the contacts
How can I reduce the time to load contacts ?
Any Thoughts?
I referred to the the following link when programming the initial method.
http://www.coderzheaven.com/2011/06/13/get-all-details-from-contacts-in-android/

BETTER SOLUTION HERE.....
private static final String[] PROJECTION = new String[] {
ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER
};
.
.
.
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION, null, null, null);
if (cursor != null) {
try {
final int nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int numberIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
String name, number;
while (cursor.moveToNext()) {
name = cursor.getString(nameIndex);
number = cursor.getString(numberIndex);
}
} finally {
cursor.close();
}
}
CHEERS...:)

Total time will depend upon what fields you are trying to access from the Contacts table.
Accessing less field means less looping , less processing and hence faster results.
Also to speed up your contacts fetch operation you can use the ContentProvideClient instead of calling query on ContentResolver every time. This will make you query the specific table rather than querying first for the required ContentProvider and then to table.
Create an instance of ContentProviderClient
ContentResolver cResolver=context.getContextResolver();
ContentProviderClient mCProviderClient = cResolver.acquireContentProviderClient(ContactsContract.Contacts.CONTENT_URI);
Then reuse this mCProviderClient to get Contacts(data from any ContentProvider) data on your call.
For example in following method, I am accessing only one field.
private ArrayList<String> fetchContactsCProviderClient()
{
ArrayList<String> mContactList = null;
try
{
Cursor mCursor = mCProviderClient.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (mCursor != null && mCursor.getCount() > 0)
{
mContactList = new ArrayList<String>();
mCursor.moveToFirst();
while (!mCursor.isLast())
{
String displayName = mCursor.getString(mCursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
mContactList.add(displayName);
mCursor.moveToNext();
}
if (mCursor.isLast())
{
String displayName = mCursor.getString(mCursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
mContactList.add(displayName);
}
}
mCursor.close();
}
catch (RemoteException e)
{
e.printStackTrace();
mContactList = null;
}
catch (Exception e)
{
e.printStackTrace();
mContactList = null;
}
return mContactList;
}

Load Contact faster like other apps doing.
I have tested this code with multiple contacts its working fine and faster like other apps within 500 ms (within half second or less) I am able to load 1000+ contacts.
Total time will depend upon what fields you are trying to access from the Contacts table.
Mange your query according to your requirement do not access unwanted fields. Accessing less field means less looping , less processing and hence faster results.
Accessing right table in contact it also help to reduce contact loading time.
Query Optimization to load contact more faster use projection
String[] projection = {
ContactsContract.Data.MIMETYPE,
ContactsContract.Data.CONTACT_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.PHOTO_URI,
ContactsContract.Contacts.STARRED,
ContactsContract.RawContacts.ACCOUNT_TYPE,
ContactsContract.CommonDataKinds.Contactables.DATA,
ContactsContract.CommonDataKinds.Contactables.TYPE
};
Selection and selection argument
String selection = ContactsContract.Data.MIMETYPE + " in (?, ?)" + " AND " /*+ ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '" + 1 + "' AND "*/ +
ContactsContract.Data.HAS_PHONE_NUMBER + " = '" + 1 + "'";
String[] selectionArgs = {
ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,
ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,
};
To order contacts alphabetically use following code
try {
Collections.sort(listview_address, new Comparator<ContactBook>() {
#Override
public int compare(ContactBook lhs, ContactBook rhs) {
return lhs.name.toUpperCase().compareTo(rhs.name.toUpperCase());
}
});
} catch (Exception e) {
e.printStackTrace();
}
Following is complete source code

You can use following code in above code that I have commented .It club the the single contact with its multiple number.To get all number associated with single contact use array in Object class.
if (contactBook == null) {
//irst contact add to avoid duplication
//load All contacts fro device
contactBook = new ContactBook(contact_id, contact_name, getResources(), photo_uri, contact_acc_type, "");
addressbook_array.put(contact_id, contactBook);
listview_address.add(contactBook);
}
String Contact_mimeType = cursor.getString(mimeTypeIdx);
//here am checking Contact_mimeType to get mobile number asociated with perticular contact and email adderess asociated
if (Contact_mimeType.equals(ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE)) {
contactBook.addEmail(contact_type, contact_data);
} else {
contactBook.addPhone(contact_type, contact_data);
}
Object class
public class ContactBook {
public int id;
public Resources res;

For loading the contacts with mininum time the optimum solution is to use the concept of projection and selection argument while querying the cursor for contacts.
this can be done in following way
void getAllContacts() {
long startnow;
long endnow;
startnow = android.os.SystemClock.uptimeMillis();
ArrayList arrContacts = new ArrayList();
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER;
Cursor cursor = ctx.getContentResolver().query(uri, new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone._ID, ContactsContract.Contacts._ID}, selection, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
cursor.moveToFirst();
while (cursor.isAfterLast() == false) {
String contactNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
int phoneContactID = cursor.getInt(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone._ID));
int contactID = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts._ID));
Log.d("con ", "name " + contactName + " " + " PhoeContactID " + phoneContactID + " ContactID " + contactID)
cursor.moveToNext();
}
cursor.close();
cursor = null;
endnow = android.os.SystemClock.uptimeMillis();
Log.d("END", "TimeForContacts " + (endnow - startnow) + " ms");
}
With above method it took 400ms(less than second) to load contacts where as in normall way it was taking 10-12 sec.
For details imformation this post might help as i took help from it

If your time increases with your data, then you are probably running a new query to fetch phones/emails for every contact. If you query for the phone/email field using ContactsContract.CommonDataKinds.Phone.NUMBER, then you will just retrieve 1 phone per contact.
The solution is to project the fields and join them by contact id.
Here is my solution in Kotlin (extracting id, name, all phones and emails):
val projection = arrayOf(
ContactsContract.Data.MIMETYPE,
ContactsContract.Data.CONTACT_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Contactables.DATA
)
val selection = "${ContactsContract.Data.MIMETYPE} in (?, ?)"
val selectionArgs = arrayOf(
ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,
ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE)
val contacts = applicationContext
.contentResolver
.query(ContactsContract.Data.CONTENT_URI, projection, selection, selectionArgs, null)
.run {
if (this == null) {
throw IllegalStateException("Cursor null")
}
val contactsById = mutableMapOf<String, LocalContact>()
val mimeTypeField = getColumnIndex(ContactsContract.Data.MIMETYPE)
val idField = getColumnIndex(ContactsContract.Data.CONTACT_ID)
val nameField = getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)
val dataField = getColumnIndex(ContactsContract.CommonDataKinds.Contactables.DATA)
while (moveToNext()) {
val mimeType = getString(mimeTypeField)
val id = getString(idField)
var contact = contactsById[id]
if (contact == null) {
val name = getString(nameField)
contact = LocalContact(id = id, fullName = name, phoneNumbers = listOf(), emailAddresses = listOf())
}
val data = getString(dataField)
when(getString(mimeTypeField)) {
ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE ->
contact = contact.copy(emailAddresses = contact.emailAddresses + data)
ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE ->
contact = contact.copy(phoneNumbers = contact.phoneNumbers + data)
}
contactsById[id] = contact
}
close()
contactsById.values.toList()
}
And for reference, my LocalContact model:
data class LocalContact(
val id: String,
val fullName: String?,
val phoneNumbers: List<String>,
val emailAddresses: List<String>
)

I think this is a better solution:
public ContentValues getAllContacts() {
ContentValues contacts = new ContentValues();
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur != null && 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 (cur.getInt(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
if (pCur != null) {
while (pCur.moveToNext()) {
String phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contacts.put(phoneNo, name);
}
pCur.close();
}
}
}
cur.close();
}
return contacts;
}
for use it you need to call this lines once:
ContentValues contacts = new ContentValues();
contacts = getAllContacts();
and when you want to get contact name by number, just use:
String number = "12345";
String name = (String) G.contacts.get(number);
this algorithm is a bit faster...
