Android: how do I get a number from Contacts by email?

My goal is to get the phone number and the e-mail of a contact.
I've tried to use one cursor but somehow it returns the same thing for phone and e-mail (either of the two, depending on tweaking some things). What I want right now is a hashtable that maps e-mails to phone numbers, or two hashtables, emailToID, and IDToPhone. This is what I have so far, but the IDs I use are not the same accross parameters (the a#a.com's phone is 123, their respective IDs are not the same and cannot be easily mapped). Would be grateful for help!
public String getPhoneByEmail(String userEmail){
final String EMAIL_URI = ContactsContract.CommonDataKinds.Email.DATA;
final String PHONE_URI = ContactsContract.CommonDataKinds.Phone.NUMBER;
Hashtable<String, Integer> emailToId = new Hashtable<>();
Hashtable<Integer, String> idToPhone = new Hashtable<>();
ContentResolver cr = getContext().getContentResolver();
Cursor cur1 = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
null,
null, null);
Cursor cur2 = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
null,
null, null);
while (cur1.moveToNext()) {
String phone = cur1.getString(cur1.getColumnIndex(PHONE_URI));
String id1 = cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Phone._ID));
idToPhone.put(Integer.parseInt(id1), phone);
}
while (cur2.moveToNext()) {
String email = cur2.getString(cur2.getColumnIndex(EMAIL_URI));
String id2 = cur2.getString(cur2.getColumnIndex(ContactsContract.CommonDataKinds.Email._ID));
emailToId.put(email, Integer.parseInt(id2));
}
cur1.close();
cur2.close();
if (emailToId.get(userEmail)!=null){
int id = emailToId.get(userEmail);
int newId = id - 2;
String phone = idToPhone.get(newId);
return phone;
}
else return "not found";
}

Got it with help from this: https://stackoverflow.com/a/4154729/6463084

Try this code to Read Contact Number/Name/Email From Phone..
public void storeContactsInLocal() {
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
// retrieve all contacts as a cursor.
Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, sortOrder);
//now we have cusror with contacts and get diffrent value from cusror.
String lastNumber = null;
while (cursor.moveToNext()) {
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String email = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
String number = phoneNumber.replaceAll("\\s+", "");
if (!number.equals(lastNumber)) {
lastNumber = number;
try {
// Save Contact in Database!
String contactDetail = "Name :" + name + " : " + "Number :" + number+ " : " + "Email :" + email;
Log.e("Contact :", contactDetail);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
Now call this Function from Your Activity like..
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Thread t = new Thread(new Runnable() {
#Override
public void run() {
storeContactsInLocal();
}
});
t.start();
}
}, 100);
Just don't forget to ask/Add Permission to read Contacts!

android fetch contact information returns null pointer exception

In my android code
I want to fetch contact's name,email and phone number as as json and then want to display.
Here is my code:
public class MainActivity extends Activity {
public TextView outputText;
String[] phoneNumber;
String[] email;
String name;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
outputText = (TextView) findViewById(R.id.textView1);
try {
//fetchContacts();
outputText.setText(fetchContacts());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public String fetchContacts() throws JSONException {
Uri CONTENT_URI = ContactsContract.Contacts.CONTENT_URI;
String _ID = ContactsContract.Contacts._ID;
String DISPLAY_NAME = ContactsContract.Contacts.DISPLAY_NAME;
String HAS_PHONE_NUMBER = ContactsContract.Contacts.HAS_PHONE_NUMBER;
Uri PhoneCONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String Phone_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;
String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;
Uri EmailCONTENT_URI = ContactsContract.CommonDataKinds.Email.CONTENT_URI;
String EmailCONTACT_ID = ContactsContract.CommonDataKinds.Email.CONTACT_ID;
String DATA = ContactsContract.CommonDataKinds.Email.DATA;
ContentResolver contentResolver = getContentResolver();
Cursor cursor = contentResolver.query(CONTENT_URI, null, null, null,
null);
List<Contact> contacts = new ArrayList<Contact>();
Gson gson = new Gson();
// Loop for every contact in the phone
if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
String contact_id = cursor
.getString(cursor.getColumnIndex(_ID));
name = cursor.getString(cursor.getColumnIndex(DISPLAY_NAME));
int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor
.getColumnIndex(HAS_PHONE_NUMBER)));
if (hasPhoneNumber > 0) {
int p = 0;
// Query and loop for every phone number of the contact
Cursor phoneCursor = contentResolver.query(
PhoneCONTENT_URI, null, Phone_CONTACT_ID + " = ?",
new String[] { contact_id }, null);
while (phoneCursor.moveToNext()) {
phoneNumber[p] = phoneCursor.getString(phoneCursor
.getColumnIndex(NUMBER));
p++;
}
phoneCursor.close();
int q = 0;
// Query and loop for every email of the contact
Cursor emailCursor = contentResolver.query(
EmailCONTENT_URI, null, EmailCONTACT_ID + " = ?",
new String[] { contact_id }, null);
while (emailCursor.moveToNext()) {
email[q] = emailCursor.getString(emailCursor
.getColumnIndex(DATA));
q++;
}
emailCursor.close();
contacts.add(new Contact(name, phoneNumber, email));
}
}
}
return gson.toJson(contacts);
}
}
But I am getting nullpointer exception error :
java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.example.contactdemo/com.example.contactdemo.MainActivity}: java.lang.NullPointerException
error found in below line of code:
phoneNumber[p] = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER));
Here I am storing phonenumber and email as array.Is there array initialization problem ?? any idea guys?

You can use these approach to finds the contact from contact list
class FetchDeviceContact extends AsyncTask<Void, Integer, String>
{
protected void onPreExecute (){
Constant.showProgressDialog(AddDeviceContactScreeen.this);
}
protected String doInBackground(Void...arg0) {
arrayList.clear();
ContentResolver cr = AddDeviceContactScreeen.this.getContentResolver();
Cursor cur = AddDeviceContactScreeen.this.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Data._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
String photoUri = cur.getString(cur.getColumnIndex(ContactsContract.Data.PHOTO_THUMBNAIL_URI));
Bitmap my_btmp = BitmapFactory.decodeResource(getResources(), R.drawable.ic_arrow_up_blue);
String email = null;
String phoneNo = null;
Cursor phonecur = AddDeviceContactScreeen.this.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{id}, null);
if (photoUri != null) {
Uri my_contact_Uri = Uri.parse(photoUri);
try {
my_btmp = MediaStore.Images.Media.getBitmap(AddDeviceContactScreeen.this.getContentResolver(), my_contact_Uri);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if (phonecur.getCount() > 0) {
while (phonecur.moveToNext()) {
phoneNo = phonecur.getString(phonecur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
}
Cursor emailCur = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
while (emailCur.moveToNext()) {
// to get the contact names
// = cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA)
email = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
if (email != null) {
System.out.println("Email============== :" + email);
}
}
emailCur.close();
ContactBean bean = new ContactBean();
bean.setName(name);
bean.setEmail(email);
bean.setImage(my_btmp);
bean.setPhone_number(phoneNo);
if (phoneNo == null || email == null) {
} else {
arrayList.add(bean);
}
}
return "";
}
protected void onProgressUpdate(Integer...a){
}
protected void onPostExecute(String result) {
Constant.cancelDialog();
}
}
new FetchDeviceContact().execute();
Create the getter and setter class for it:-
public class ContactBean {
String name;
String email;
Bitmap image;
String phone_number;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Bitmap getImage() {
return image;
}
public void setImage(Bitmap image) {
this.image = image;
}
public String getPhone_number() {
return phone_number;
}
public void setPhone_number(String phone_number) {
this.phone_number = phone_number;
}
}

I think you should fix :
if (phoneCursor.movetoFirst()){
while (!phoneCursor.isAfterLast()) {
phoneNumber[p] = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER));
p++;
phoneCursor.movetoNext();
}
}

Here:
phoneNumber[p] = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER));
NullPointerException caused because phoneNumber is null and not initialized.
Use Cursor. getCount() to initialize it as:
phoneNumber = new String[phoneCursor.getCount()];
phoneCursor.moveToFirst();
while (phoneCursor.moveToNext()) {
//..your code here..
}

Fetching contacts in android is very slow

I had written a code to fetch contact name, phone number and image from Contacts and to display it on a listview in android. It's working fine but taking more time to load. I had tried to use multi-threading in some parts of the code. But the loading time is not decreased.
Here is the onCreate() method:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lvDetail = (ListView) findViewById(R.id.listView1);
fetchcontacts();
lvDetail.setAdapter(new MyBaseAdapter(context, myList));
}
Here is the code for fetch contacts:
private void fetchcontacts() {
// TODO Auto-generated method stub
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
int count = cursor.getCount();
if (count > 0) {
Toast.makeText(context, "count >0", Toast.LENGTH_SHORT).show();
while (cursor.moveToNext()) {
String columnId = ContactsContract.Contacts._ID;
int cursorIndex = cursor.getColumnIndex(columnId);
String id = cursor.getString(cursorIndex);
name = cursor.getString(cursor
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Toast.makeText(context, "Toast 1", Toast.LENGTH_SHORT).show();
int numCount = Integer.parseInt(cursor.getString(cursor
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)));
if (numCount > 0) {
Toast.makeText(context, "Toast 2", Toast.LENGTH_SHORT).show();
Cursor phoneCursor = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
CommonDataKinds.Phone.CONTACT_ID+" = ?", new String[] { id
}, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
while (phoneCursor.moveToNext()) {
Toast.makeText(context, "Toast 3", Toast.LENGTH_SHORT).show();
phoneNo = phoneCursor.getString(phoneCursor
.getColumnIndex(ContactsContract.CommonDataKinds.
Phone.NUMBER));
String image_uri = phoneCursor
.getString(phoneCursor
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
if (image_uri != null) {
Toast.makeText(context, "Toast 4", Toast.LENGTH_SHORT).show();
System.out.println(Uri.parse(image_uri));
try {
bitmap = MediaStore.Images.Media
.getBitmap(this.getContentResolver(),
Uri.parse(image_uri));
// sb.append("\n Image in Bitmap:" + bitmap);
// System.out.println(bitmap);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Toast.makeText(context, name, Toast.LENGTH_SHORT).show();
getDataInList(name,phoneNo,bitmap);
name=null;
phoneNo=null;
Drawable myDrawable = getResources().getDrawable(R.drawable.star1);
bitmap = ((BitmapDrawable) myDrawable).getBitmap();
}
phoneCursor.close();
}
}
}
Here the setAdapter() function of the listview is working after fetching all the contacts to an ArrayList. do anyone have idea about how to display the contacts during fetching contacts? any sample code?

1.Read the Columns from the Cursor which you required only ,According to your requirement you just need _ID,HAS_PHONE_NUMBER,DISPLAY_NAME ,so change the Cursor reading
Cursor cursor = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI,
new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.HAS_PHONE_NUMBER,
ContactsContract.Contacts.DISPLAY_NAME }, null, null,
ContactsContract.Contacts.DISPLAY_NAME + " ASC");
2.Dont do the time taking process in the UI thread..Use AsyncTask instead
Note : This two steps will resolve to some extent..but not completely

I made it by reduce repeated query wich is expensive. Best of my solution is that method found all mobile phones and email for each contact and insert to list for every contact values. It is fast as storm now :)
//contact entity
public class MobileContact {
public String name;
public String contact;
public Type type;
public MobileContact(String contact, Type type) {
name = "";
this.contact = contact;
this.type = type;
}
public MobileContact(String name, String contact, Type type) {
this.name = name;
this.contact = contact;
this.type = type;
}
public enum Type {
EMAIL, PHONE
}
#Override
public String toString() {
return "MobileContact{" +
"name='" + name + '\'' +
", contact='" + contact + '\'' +
", type=" + type +
'}';
}
}
// method for collect contacts
public List<MobileContact> getAllContacts() {
log.debug("get all contacts");
List<MobileContact> mobileContacts = new ArrayList<>();
ContentResolver contentResolver = context.getContentResolver();
// add all mobiles contact
Cursor phonesCursor = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.CONTACT_ID}, null, null, null);
while (phonesCursor != null && phonesCursor.moveToNext()) {
String contactId = phonesCursor.getString(phonesCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
String phoneNumber = phonesCursor.getString(phonesCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)).replace(" ", "");
mobileContacts.add(new MobileContact(contactId, phoneNumber, MobileContact.Type.PHONE));
}
if (phonesCursor != null) {
phonesCursor.close();
}
// add all email contact
Cursor emailCursor = contentResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, new String[]{ContactsContract.CommonDataKinds.Email.DATA, ContactsContract.CommonDataKinds.Email.CONTACT_ID}, null, null, null);
while (emailCursor != null && emailCursor.moveToNext()) {
String contactId = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.CONTACT_ID));
String email = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
mobileContacts.add(new MobileContact(contactId, email, MobileContact.Type.EMAIL));
}
if (emailCursor != null) {
emailCursor.close();
}
// get contact name map
Map<String, String> contactMap = new HashMap<>();
Cursor contactsCursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, new String[]{ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.HAS_PHONE_NUMBER}, null, null, ContactsContract.Contacts.DISPLAY_NAME);
while (contactsCursor != null && contactsCursor.moveToNext()) {
String contactId = contactsCursor.getString(contactsCursor.getColumnIndex(ContactsContract.Contacts._ID));
String contactName = contactsCursor.getString(contactsCursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
contactMap.put(contactId, contactName);
}
if (phonesCursor != null) {
phonesCursor.close();
}
// replace contactId to display name
for (MobileContact mobileContact : mobileContacts) {
String displayName = contactMap.get(mobileContact.name);
mobileContact.name = displayName != null ? displayName : "";
}
// sort list by name
Collections.sort(mobileContacts, new Comparator<MobileContact>() {
#Override
public int compare(MobileContact c1, MobileContact c2) {
return c1.name.compareTo(c2.name);
}
});
return mobileContacts;
}

The contacts in larse size use in backround task.
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number[i]));
ContentResolver contentResolver = getContentResolver();
Cursor search = contentResolver.query(uri, new String[]{ContactsContract.PhoneLookup._ID,
ContactsContract.PhoneLookup.DISPLAY_NAME}, null, null, null);
try {
if (search != null && search.getCount() > 0) {
search.moveToNext();
name = search.getString(search.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
id = search.getString(search.getColumnIndex(ContactsContract.Data._ID));
System.out.println("name" + name + "id" + id);
/* tv_name.setText(name);
tv_id.setText(id);
tv_phone.setText(number);*/
}
} finally {
if (search != null) {
search.close();
}
}

Fastest way for me soo far .
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 , }

How to query all the details of the Contact at once

EDIT:A list of what I consider important contact details:
1.NAME
2.PHONE NUMBER
3.EMAIL ADDRESS
4.WEBSITE
5.PHYSICAL ADDRESS
I would prefer to do this using a pre-fetched contactId...using only one cursor to get all of the data specified.I,preferably would like to find the right query to do this:
I would like to get all of the important details of a Contact at once,I am using the following code to do this:
public void getAllDataByContactId(int contactId)
{
Log.d(TAG, "Seriously scared it might not work");
String phoneNo="Phone disconnected";
String email="Email could not be delivered";
String website="Website 404";
String address="Number 13,Dark Street,Area 51,Bermuda Trianlge";
String name="Clint Eastwood";
int hasPhoneNumber;
String selection=ContactsContract.Data.CONTACT_ID+"=?";
String[] selectionArgs={String.valueOf(contactId)};
Cursor c=context.getContentResolver().query(ContactsContract.Data.CONTENT_URI, null,selection, selectionArgs,ContactsContract.Data.TIMES_CONTACTED);
if(c!=null && c.getCount()>0)
{
while(c.moveToNext())
{
phoneNo=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.d(TAG, "Phone number: "+phoneNo);
email=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Email.ADDRESS));
Log.d(TAG, "Email: "+email);
website=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Website.URL));
Log.d(TAG, "Website :"+website);
address=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS));
name=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME));
Log.d(TAG, "Name :"+name);
}
}
}
However,although this does not throw an error it shows many rows consisting of an empty string interspresed with the actual values.How do I write a query that cuts out the noise?
I have tried this and this gets me all the values:
String selection=ContactsContract.Data.CONTACT_ID+"=? AND "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=?";
String[] selectionArgs={String.valueOf(contactId),ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.Website.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE};

Too late to answer, but maybe it can help someone in the future.
My solution for this question with only one while cycle and query:
private void fetchContacts(ContentResolver contentResolver) {
if (contentResolver == null) return;
Cursor cursor = contentResolver.query(ContactsContract.Data.CONTENT_URI,
null, null, null, null);
if (cursor == null || cursor.getCount() <= 0) {
return;
}
String prevId = "";
String contactId = "";
PersonContact personContact = null;
while (cursor.moveToNext()) {
String company = "";
String columnName = cursor.getString(cursor.getColumnIndex("mimetype"));
if (columnName.equals(ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE)) {
company = cursor.getString(cursor.getColumnIndex("data1"));
}
String email = "";
if (columnName.equals(ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE)) {
email = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
}
String phone = "";
if (columnName.equals(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE)) {
phone = cursor.getString(cursor.getColumnIndex("data1"));
}
String first = "";
String last = "";
if (columnName.equals(ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE)) {
first = cursor.getString(cursor.getColumnIndex("data2"));
last = cursor.getString(cursor.getColumnIndex("data3"));
}
if (!prevId.equals(contactId)) {
if (!TextUtils.isEmpty(prevId)) {
addFilteredList(personContact);
allContacts.put(prevId, personContact);
}
prevId = contactId;
personContact = new PersonContact();
} else {
if (personContact != null) {
personContact.id = prevId;
if (TextUtils.isEmpty(personContact.company)) personContact.company = company;
if (TextUtils.isEmpty(personContact.firstName)) personContact.firstName = first;
if (TextUtils.isEmpty(personContact.lastName)) personContact.lastName = last;
if (!TextUtils.isEmpty(email) && personContact.emails.size() == 0) {
personContact.emails.add(email);
}
if (!TextUtils.isEmpty(phone) && personContact.phoneNumbers.size() == 0) {
personContact.phoneNumbers.add(phone);
}
}
}
contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
}
cursor.close();
}
As you can see, I used the prevId field, because cursor.moveToNext performs several times for one contact (once for first and last names, one for phone, etc.). After each iteration, I check the previous contact identifier with the current identifier and, if it is false, I update the fields in the personContact model.

May not be the best solution. But this is how I achieved it.

Read all contacts' phone numbers in android

I'm using this code to retrieve all contact names and phone numbers:
String[] projection = new String[]
{
People.NAME,
People.NUMBER
};
Cursor c = ctx.getContentResolver().query(People.CONTENT_URI, projection, null, null, People.NAME + " ASC");
c.moveToFirst();
int nameCol = c.getColumnIndex(People.NAME);
int numCol = c.getColumnIndex(People.NUMBER);
int nContacts = c.getCount();
do
{
// Do something
} while(c.moveToNext());
However, this will only return the primary number for each contact, but I want to get the secondary numbers as well. How can i do this?

Following code shows an easy way to read all phone numbers and names:
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
while (phones.moveToNext())
{
String name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
NOTE: getContentResolver is a method from the Activity context.

You can read all of the telephone numbers associated with a contact in the following manner:
Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, personId);
Uri phonesUri = Uri.withAppendedPath(personUri, People.Phones.CONTENT_DIRECTORY);
String[] proj = new String[] {Phones._ID, Phones.TYPE, Phones.NUMBER, Phones.LABEL}
Cursor cursor = contentResolver.query(phonesUri, proj, null, null, null);
Please note that this example (like yours) uses the deprecated contacts API. From eclair onwards this has been replaced with the ContactsContract API.

This code shows how to get all phone numbers for each contact.
ContentResolver cr = getActivity().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()) {
int phoneType = pCur.getInt(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.TYPE));
String phoneNumber = pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
switch (phoneType) {
case Phone.TYPE_MOBILE:
Log.e(name + "(mobile number)", phoneNumber);
break;
case Phone.TYPE_HOME:
Log.e(name + "(home number)", phoneNumber);
break;
case Phone.TYPE_WORK:
Log.e(name + "(work number)", phoneNumber);
break;
case Phone.TYPE_OTHER:
Log.e(name + "(other number)", phoneNumber);
break;
default:
break;
}
}
pCur.close();
}
}
}

In case it helps, I've got an example that uses the ContactsContract API to first find a contact by name, then it iterates through the details looking for specific number types:
How to use ContactsContract to retrieve phone numbers and email addresses

You can get all phone contacts using this:
Cursor c = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.RawContacts.ACCOUNT_TYPE },
ContactsContract.RawContacts.ACCOUNT_TYPE + " <> 'google' ",
null, null);
check complete example HERE...........

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 <span id="IL_AD4" class="IL_AD">phone
// number</span>
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();

Accepted answer working but not given unique numbers.
See this code, it return unique numbers.
public static void readContacts(Context context) {
if (context == null)
return;
ContentResolver contentResolver = context.getContentResolver();
if (contentResolver == null)
return;
String[] fieldListProjection = {
ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER,
ContactsContract.Contacts.HAS_PHONE_NUMBER
};
Cursor phones = contentResolver
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI
, fieldListProjection, null, null, null);
HashSet<String> normalizedNumbersAlreadyFound = new HashSet<>();
if (phones != null && phones.getCount() > 0) {
while (phones.moveToNext()) {
String normalizedNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER));
if (Integer.parseInt(phones.getString(phones.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
if (normalizedNumbersAlreadyFound.add(normalizedNumber)) {
String id = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.d("test", " Print all values");
}
}
}
phones.close();
}
}

In the same way just get their other numbers using the other "People" references
People.TYPE_HOME
People.TYPE_MOBILE
People.TYPE_OTHER
People.TYPE_WORK

This one finally gave me the answer I was looking for. It lets you retrieve all the names and phone numbers of the contacts on the phone.
package com.test;
import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
public class TestContacts extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if (cur != null && cur.getCount() > 0) {
while (cur.moveToNext()) {
if (Integer.parseInt.equals(cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER)))) {
String id = cur.getString(cur.getColumnIndex(
ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
int i = 0;
int pCount = pCur.getCount();
String[] phoneNum = new String[pCount];
String[] phoneType = new String[pCount];
while (pCur != null && pCur.moveToNext()) {
phoneNum[i] = pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
phoneType[i] = pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.TYPE));
i++;
}
}
}
}
}
}

I fixed my need belove
manifest permissions
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>
<!-- Read Contacts from phone -->
<uses-permission android:name="android.permission.read_contacts" />
<uses-permission android:name="android.permission.read_phone_state" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
Note: After giving permissions at manifest some mobile phones can deny if so you need to go Settings--> Applications--> find your application click on it and
turn On the permissions needed
btn_readallcontacks.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
List<User> userList = new ArrayList<User>();
while (phones.moveToNext()) {
User user = new User();
user.setNamee(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
user.setPhone(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
userList.add(user);
Log.d(TAG, "Name : " + user.getNamee().toString());
Log.d(TAG, "Phone : " + user.getPhone().toString());
}
phones.close();
}
});

You can get all the contact all those which have no number and all those which have no name from this piece of code
public void readContacts() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY + " ASC");
ContactCount = cur.getCount();
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));
String phone = null;
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()) {
phone = pCur.getString(
pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
System.out.println("phone" + phone);
}
pCur.close();
}
if (phone == "" || name == "" || name.equals(phone)) {
if (phone.equals(""))
getAllContact.add(new MissingPhoneModelClass("No Number", name, id));
if (name.equals("") || name.equals(phone))
getAllContact.add(new MissingPhoneModelClass(phone, "No Name", id));
} else {
if(TextUtils.equals(phone,null)){
getAllContact.add(new MissingPhoneModelClass("No Number", name, id));
}
else {
getAllContact.add(new MissingPhoneModelClass(phone, name, id));
}
}
}
}
}
One thing can be done you have to give the permission in the manifest for contact READ and WRITE
After that you can create the model class for the list which can be use to add all the contact here is the model class
public class PhoneModelClass {
private String number;
private String name;
private String id;
private String rawId;
public PhoneModelClass(String number, String name, String id, String rawId) {
this.number = number;
this.name = name;
this.id = id;
this.rawId = rawId;
}
public PhoneModelClass(String number, String name, String id) {
this.number = number;
this.name = name;
this.id = id;
}
public String getRawId() {
return rawId;
}
public void setRawId(String rawId) {
this.rawId = rawId;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}
Enjoy :)

Load contacts in background using CursorLoader:
CursorLoader cursor = new CursorLoader(this, ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
Cursor managedCursor = cursor.loadInBackground();
int number = managedCursor.getColumnIndex(ContactsContract.Contacts.Data.DATA1);
int name = managedCursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
int index = 0;
while (managedCursor.moveToNext()) {
String phNumber = managedCursor.getString(number);
String phName = managedCursor.getString(name);
}

Here's how to use ContentsContract API to fetch your contacts in your Phone Book.
You'll need to add these permissions in your AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
Then, you can run this method to loop through all your contacts.
Here's an example to query fields like Name and Phone Number, you can configure yourself to use CommonDataKinds, it query other fields in your Contact.
https://developer.android.com/reference/android/provider/ContactsContract.CommonDataKinds
private fun readContactsOnDevice() {
val context = requireContext()
if (ContextCompat.checkSelfPermission(
context, Manifest.permission.WRITE_CONTACTS
) != PackageManager.PERMISSION_GRANTED &&
ContextCompat.checkSelfPermission(
context, Manifest.permission.READ_CONTACTS
) != PackageManager.PERMISSION_GRANTED
) {
requestPermissions(
arrayOf(Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS), 1
)
return
}
val contentResolver = context.contentResolver
val contacts = contentResolver.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, null, null, null
)
while (contacts?.moveToNext() == true) {
val name = contacts.getString(
contacts.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)
)
val phoneNumber = contacts.getString(
contacts.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)
)
Timber.i("Name: $name, Phone Number: $phoneNumber")
}
}
