Unable to load contacts - android

I have Tried number of available examples which helps to load contacts from phone. It works fine on emulator but when i try on real time mobile then it crashes. Can any one send me tested piece of code which is working flawless. then i can compare with my code.
one failed code example.
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
if (phones.getCount() > 0)
{
while (phones.moveToNext())
{
name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
Kindly help.

Be sure that phones is not null. If not null add this row to move pointer to 1st phone:
cursor.moveToFirst();
Here is snippets of code as example how it should work:
Uri contactData = data.getData();
//Cursor cursor = managedQuery(contactData, null, null, null, null);
Cursor cursor = cr.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));
if (Integer.parseInt(cursor.getString(
cursor.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 number = pCur.getString(pCur.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));
break; // ? we want only 1 value
}
pCur.close();
}
cursor.close();
Suppose it will help you

First,add this in manifest file:
<uses-permission android:name="android.permission.READ_CONTACTS"/>
to your AndroidManifest.xml file, then you can loop through your phone contacts like this:
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
while (cursor.moveToNext()) {
String contactId = cursor.getString(cursor.getColumnIndex(
ContactsContract.Contacts._ID));
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (Boolean.parseBoolean(hasPhone)) {
// You know it has a number so now query it like this
Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null);
while (phones.moveToNext()) {
String phoneNumber = phones.getString(phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
}
Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null);
while (emails.moveToNext()) {
// This would allow you get several email addresses
String emailAddress = emails.getString(
emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
}
emails.close();
}
cursor.close();

Query for selecting a phone number from the contact list

I have a problem with query in Android.
<uses-permission android:name="android.permission.READ_CONTACTS" />
I put permission in AndroidManifest.xml
String contactNumber = "";
if (requestCode == PICK_CONTACT && resultCode == RESULT_OK) {
Uri contctDataVar = data.getData();
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(contctDataVar, null, null, null, null);
if(cursor.moveToFirst()){
contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String contactID = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if(hasPhone.equalsIgnoreCase("1")){
Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactID, null, null );
if(phones.moveToFirst()){
contactNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
}
}
}
contactName is ok, but
Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactID, null, null );
Not working, the application will be closed.What it wrong ?
Below is a complete code for get contact number

while (phones.moveToNext())
{
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

Reading a specific contact from its ID on android database

I need to set the cursor to a specific contact that i have its id
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null,null, null, null);
I have that code for all the database, how can I optimize it?
I need the cursor to return the name and the default number of the contact
thank you
You actually need two cursors. One for name & id and another one for phone number.
Cursor c = managedQuery(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (c.moveToFirst()) {
name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
fullName = c.getString(c.getColumnIndex("display_name_alt"));
id = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));
if (Integer.parseInt(c.getString(c.getColumnIndex
(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
//phone number
Cursor phones = getContentResolver().query(Phone.CONTENT_URI,
null,
Phone.CONTACT_ID + " = " + id,
null,
null);
while (phones.moveToNext()) {
String number_type = phones.getString(phones.getColumnIndex
(ContactsContract.CommonDataKinds.Phone.TYPE));
if(number_type.equalsIgnoreCase("1"))
number1 = phones.getString(phones.getColumnIndex
(ContactsContract.CommonDataKinds.Phone.NUMBER));
if(number_type.equalsIgnoreCase("2"))
number2 = phones.getString(phones.getColumnIndex
(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
}
}
c.close();
cursor = getContentResolver().query(Phone.CONTENT_URI,
null, Phone.CONTACT_ID + "=?", new String[] { id },
Phone.DISPLAY_NAME + " ASC");

retriveing contacts in android 2.2

Hi i need to get contact details in edittext when i press a button.But i am getting it right when i have only one contact and it is showing an execption if it has more than one contact.Here is my code & i dont know what should i add to it.So help if anyone knows.Thanks in Adv.
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
while (cursor.moveToNext()) {
String contactId = cursor.getString(cursor.getColumnIndex(
ContactsContract.Contacts._ID));
Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId , null, null);
startManagingCursor(phones);
while (phones.moveToNext()) {
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
e2.setText(phoneNumber);
}
//}
Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null);
startManagingCursor(emails);
while (emails.moveToNext()) {
// This would allow you get several email addresses
String emailAddress = emails.getString(
emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
e3.setText(emailAddress);
}
Cursor street = getContentResolver().query(ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.StructuredPostal.CONTACT_ID + " = " + contactId, null, null);
startManagingCursor(street);
while (street.moveToNext()) {
String streetname=street.getString(street.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS));
e1.setText(streetname);
}
phones.close();
emails.close();
street.close();
cursor.close();
you can visit Contact Information where all contacts and information is queried
Change your while condition in while(!cursor.isAfterLast()).

Retrieving Android Contacts

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 (name.equals(selected) && 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);
finalsend = ContactsContract.CommonDataKinds.Phone.NUMBER;
while (pCur.moveToNext()) {
}
pCur.close();
}
The code is supposed to look through contacts to find one that matches the "selected" variable which appears to work fine but then it is supposed to switch to the ContactsContract.CommonDataKinds.Phone.CONTENT_URI and find the same contact by matching up the ID's and give me the phone number saved for that contact.
Every time it returns "Data1", what am I doing wrong? It's probably a stupid mistake but any help is appreciated.
Following code snippet is working for me:
String id , name;
ContentResolver cr = getContentResolver();
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, sortOrder);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
name = cur.getString( cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Log.i(tag, "Id is "+ id+"\t Name is"+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()) {
// Do something with phones
int phNumber = pCur.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER);
String phn = pCur.getString(phNumber);
Log.i("phn number", phn);
}
pCur.close();
}
}
}

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;
}
