how to fetch local phone contacts effeciently - android

I am using the below code to fetch the local phone contacts. It is working fine and also fetching the contacts very fast.
But the problem comes here, in my contact list there are few contacts that are having multiple Emails and multiple phone numbers.
In case of multiple phone or emails address it repeats the name of the same person multiple times.
And if i change
ContactsContract.CommonDataKinds.Email.CONTENT_URI
to ContactsContract.CommonDataKinds.Phone.CONTENT_URI then it will repeat name according to the number of phone number exists for a contact. Please help
private static final String[] PROJECTION = new String[]{
ContactsContract.CommonDataKinds.Email.CONTACT_ID,
ContactsContract.CommonDataKinds.Nickname.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Email.DATA,
ContactsContract.CommonDataKinds.Phone.NUMBER,
};
ContentResolver cr = mContext.getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, PROJECTION, null, null, null);
if (cursor != null) {
try {
final int contactIdIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.CONTACT_ID);
final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int emailIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
final int phoneIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
long contactId;
String displayName, email, phone, photo;
while (cursor.moveToNext()) {
mNK_UserModel = new NK_Contact();
contactId = cursor.getLong(contactIdIndex);
displayName = cursor.getString(displayNameIndex);
//Adding display name
mNK_UserModel.setFirstName(displayName);
Util.DEBUG_LOG(1, "contact", "contact id :" + contactId);
al_PhoneContacts.add(mNK_UserModel);
}
} finally {
cursor.close();
}
}

If i had to guess i would say you are missing a "break" in your while-loop. Since the cursor tries to fetch the next available column entry. But have a look at my solution which worked for me in the past.
It uses a seperate cursor for each row which gives you more control over the data.
Map<String, String> contactDataMap = new HashMap<String, String>();
Uri contactData = data.getData();
Cursor cursor = getContentResolver().query(contactData, null, null, null, null);
cursor.moveToFirst();
String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
String id = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
contactDataMap.put(NAME, (name != null)?name:"");
if (Integer.parseInt(cursor.getString(
cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{id},
null);
while (pCur.moveToNext()) {
String number = pCur.getString(pCur.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));
contactDataMap.put(PHONE, (number != null)?number:"");
break;
}
pCur.close();
}
Cursor emailCur = getContentResolver().query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
while (emailCur.moveToNext()) {
String email = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
contactDataMap.put(MAIL, (email != null)?email:"");
break;
}
emailCur.close();
cursor.close();

Contacts name are coming null while cursor has all contacts

I'm getting 'name = null' in this code, while cursor has all my contacts in it, i tried many different ways but it all does the same thing.
String[] contact_names, mobile_numbers;
Cursor cursor = getActivity().getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,null, null, null);
while (cursor.moveToFirst()) {
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
contact_names[contact_names.length] = name;
Cursor phones = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?" + contactId, null, null);
while (phones.moveToNext()) {
String number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
mobile_numbers[mobile_numbers.length] = number;
}
phones.close();
}
cursor.close();
You don't need to query multiple times, use the following to get it all in one query,
String[] PROJECTION_MAIN = new String[]{
ContactsContract.Contacts._ID,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.Contacts.DISPLAY_NAME
};
Cursor cursor = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
PROJECTION_MAIN, null, null, null);
while (cursor.moveToNext()) {
String contact_id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String phone = cleanNumber(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)), context);
}

How to get contacts with email or phone number

How can I get a list of contacts that either have a phone number or an email in Android.
I'm a bit confused with the contracts and how can I join the info.
Thank you
Here is how I fetched contacts with email and phone number. The Contact object is just a simple pojo that I created. This code is in an AsyncTask that I run after the user has provided permission to access Contacts.
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
do {
// get the contact's information
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Integer hasPhone = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
// get the user's email address
String email = null;
Cursor ce = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", new String[]{id}, null);
if (ce != null && ce.moveToFirst()) {
email = ce.getString(ce.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
ce.close();
}
// get the user's phone number
String phone = null;
if (hasPhone > 0) {
Cursor cp = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
if (cp != null && cp.moveToFirst()) {
phone = cp.getString(cp.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
cp.close();
}
}
// if the user user has an email or phone then add it to contacts
if ((!TextUtils.isEmpty(email) && android.util.Patterns.EMAIL_ADDRESS.matcher(email).matches()
&& !email.equalsIgnoreCase(name)) || (!TextUtils.isEmpty(phone))) {
Contact contact = new Contact();
contact.name = name;
contact.email = email;
contact.phoneNumber = phone;
contacts.add(contact);
}
} while (cursor.moveToNext());
// clean up cursor
cursor.close();
}
For DISPLAY_NAME you can use the following:
private final String DISPLAY_NAME = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ?
ContactsContract.Contacts.DISPLAY_NAME_PRIMARY : ContactsContract.Contacts.DISPLAY_NAME;
Here is a link to an AsyncTask Example that I use with this.
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) {
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
String phoneNo = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Toast.makeText(NativeContentProvider.this, "Name: " + name + ", Phone No: " + phoneNo, Toast.LENGTH_SHORT).show();
}
pCur.close();
}
}
}

Getting name and email from contact list is very slow

I'm implementing an AutoCompleteTextView and I need Name and E-Mail of all my contacts.
I found this snippet that I'm running asynchronously but it's very slow.
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));
Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", new String[]{id}, null);
while (emailCur.moveToNext()) {
String email = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
autoCompleteAdapter.add(name + " - " + email);
}
emailCur.close();
}
}
}
I'm performing a sort of inner query and I think that's the problem. Is there a way to tune it and make it faster?
private static final String[] PROJECTION = new String[] {
ContactsContract.CommonDataKinds.Email.CONTACT_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Email.DATA
};
...
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, PROJECTION, null, null, null);
if (cursor != null) {
try {
final int contactIdIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.CONTACT_ID);
final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int emailIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
long contactId;
String displayName, address;
while (cursor.moveToNext()) {
contactId = cursor.getLong(contactIdIndex);
displayName = cursor.getString(displayNameIndex);
address = cursor.getString(emailIndex);
...
}
} finally {
cursor.close();
}
}
few notes:
use just ContactsContract.CommonDataKinds.Email.CONTENT_URI to get information you need, see ContactsContract.CommonDataKinds.Email for information what columns you can query
use projection to get only those columns you really need, you save some memory and increase query performance
get column indexes only once, just before the while cycle
You should not query directly the ContactsContract.Contacts
Make just one query on the ContactsContract.CommonDataKinds with the email data kind.
The ContactsContract.CommonDataKinds.Email inherits a lot of other interfaces that you can use to build your projection. (see inherited constants from the documentation)
For example :
import android.provider.ContactsContract.CommonDataKinds.Email;
[...]
public static final String[] EMAILS_PROJECTION = new String[] {
Email._ID,
Email.DISPLAY_NAME_PRIMARY,
Email.ADDRESS
};
to be used with the
Email.CONTENT_URI
You can retrieve a lot of information (such as user id, user display name ...) directly from the email data kind.
EDIT:
I just realized you're trying to build an AutoCompleteTextView.
You should override the runQueryOnBackgroundThread method and the convertToString of your CursorAdapter and use the Email.CONTENT_FILTER_URI
I really strongly suggest you to take a look at the ApiDemo samples.
Especially the AutoComplete4.java sample that you can find HERE.
ContentResolver cr = mContext.getContentResolver();
Cursor cursor = mContext.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, PROJECTION, "HAS_PHONE_NUMBER <> 0", null, null);
if (cursor!= null)
{
final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int numberIndex = cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);
final int idIndex= cursor.getColumnIndex(ContactsContract.Contacts._ID);
String displayName, number = null, idValue;
while (cursor.moveToNext())
{
displayName = cursor.getString(displayNameIndex);
idValue= cursor.getString(idIndex);
Cursor phones = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, "contact_id = '" + idValue + "'", null, null);
phones.moveToFirst();
try
{
number = phones.getString(phones.getColumnIndex("data1"));
}
catch (CursorIndexOutOfBoundsException e)
{
}
phones.close();
userList.add(new ContactModel(displayName, number, null));
}
}

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.

How to get contact email id?

I have a listview of all the contact names in the phone. I want to get the email id (if contact have one) of the contact which I click on in the listview. How can I do this?
Use the following code to get all email ids. I checked the code. It is working.
public static void getContactEmails(Context context) {
String emailIdOfContact = null;
int emailType = Email.TYPE_WORK;
String contactName = null;
ContentResolver cr = context.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(BaseColumns._ID));
contactName = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
// Log.i(TAG,"....contact name....." +
// contactName);
cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
Cursor emails = cr.query(Email.CONTENT_URI, null,
Email.CONTACT_ID + " = " + id, null, null);
while (emails.moveToNext()) {
emailIdOfContact = emails.getString(emails
.getColumnIndex(Email.DATA));
// Log.i(TAG,"...COntact Name ...."
// + contactName + "...contact Number..."
// + emailIdOfContact);
emailType = emails.getInt(emails
.getColumnIndex(Phone.TYPE));
}
emails.close();
}
}// end of contact name cursor
cur.close();
}
Phone Numbers
Phone numbers are stored in their own table and need to be queried separately. To query the phone number table use the URI stored in the SDK variable ContactsContract.CommonDataKinds.Phone.CONTENT_URI. Use a WHERE conditional to get the phone numbers for the specified contact.
if (Integer.parseInt(cur.getString(
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);
while (pCur.moveToNext()) {
// Do something with phones
}
pCur.close();
}
Perform a second query against the Android contacts SQLite database. The phone numbers are queried against the URI stored in ContactsContract.CommonDataKinds.Phone.CONTENT_URI. The contact ID is stored in the phone table as ContactsContract.CommonDataKinds.Phone.CONTACT_ID and the WHERE clause is used to limit the data returned.
Email Addresses
Querying email addresses is similar to phone numbers. A query must be performed to get email addresses from the database. Query the URI stored in ContactsContract.CommonDataKinds.Email.CONTENT_URI to query the email address table
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));
}
emailCur.close();
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_FILTER_URI,Uri.encode(name.toString().trim()));
Cursor mapContact = getContext().getContentResolver().query(uri, new String[]{PhoneLookup._ID}, null, null, null);
if(mapContact.moveToNext())
{
String _id = mapContact.getString(mapContact.getColumnIndex(ContactsContract.Contacts._ID));
}
Xamarin Version of Sunil's answer. Took me a while, but I figured it out.
ContentResolver cr = ContentResolver;
string contactName = null;
var cur = cr.Query(ContactsContract.Contacts.ContentUri,null,null,null,null);
if (cur.MoveToFirst())
{
do
{
string id = cur.GetString(cur.GetColumnIndex(BaseColumns.Id));
contactName = cur.GetString(cur.GetColumnIndex(ContactsContract.Contacts.InterfaceConsts.DisplayName));
var emails = cr.Query(ContactsContract.CommonDataKinds.Email.ContentUri, null, ContactsContract.CommonDataKinds.Email.InterfaceConsts.ContactId + " = " + id, null, null);
if (emails.MoveToFirst()) {
do
{
// This is where it loops through if there are multiple Email addresses
var email = emails.GetString(emails.GetColumnIndex(ContactsContract.CommonDataKinds.Email.InterfaceConsts.Data));
} while (emails.MoveToNext());
}
} while (cur.MoveToNext());
}
I am using below code. it is working fine. checked it.
ArrayList<ContactInfo> listContactsData = new ArrayList<>();
// Retrieve Email address
Cursor emailCursor = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
while (emailCursor.moveToNext()) {
// This would allow you get email addresses
String email = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)); String emailType = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
Log.e(“Email :“,” ”+email)
objContact.strEmail = email;
}
emailCur.close();
listContactsData.add(objContact);
Uri contactData = data.getData();
Cursor c = getContentResolver().query(contactData, null, null, null, null);
if (c.moveToFirst()) {
String contactId = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));
String hasNumber = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
String email= "";
if (Integer.valueOf(hasNumber) == 1) {
Cursor numbers = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null);
while (numbers.moveToNext()) {
email= numbers.getString(numbers.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
//Toast.makeText(getApplicationContext(), "Number=" + num, Toast.LENGTH_LONG).show();
//asdasdasdsa
if(getEmail(email).isEmpty()){
Toast.makeText(this, "Email Not Found In That Contact Try Another", Toast.LENGTH_SHORT).show();
}
else {
edt_email_contact.setText("" + getEmail(email));
} }
}
}
break;
