How to fetch recent and favourite contacts in android?

I have been trying to fetch recent and favorites contacts but every time i get error .
i am storing contacts in database after fetching .
cannot read column -1
and sometimes it says cursor not initialized properly.
please help me .
Here is my code.
ContentResolver cr = getActivity().getContentResolver();
/* Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, null );*/
Cursor cur=cr.query(CallLog.Calls.CONTENT_URI,null,CallLog.Calls.DATE, null,null);
String phone = null;
String emailContact = null;
String image_uri;
Bitmap bitmap;
final SQLiteDatabase mDb = db.getWritableDatabase();
mDb.beginTransaction();
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));
image_uri = cur
.getString(cur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
if (Integer
.parseInt(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
System.out.println("name : " + name + ", ID : " + id);
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[]{id}, null);
Log.e("pCur","dfgfdg "+pCur.getCount());
while (pCur.moveToNext())
{
phone = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
// contactid=pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
/* phonenumber.add(pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));`*/
}
pCur.close();
Cursor emailCur = cr.query
(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = ?", new String[]{id}, null);
while (emailCur.moveToNext())
{
emailContact = emailCur
.getString(emailCur
.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
if(TextUtils.isEmpty(emailContact)||emailContact.equalsIgnoreCase(null)||emailContact.equalsIgnoreCase(""))
{
emailContact="";
Log.e("isEmpty","isEmpty " + emailContact);
}
else
{
Log.e("gfdszfg","Email " + emailContact);
}
/* emailType = emailCur
.getString(emailCur
.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));*/
Log.e("gfdszfg","Email " + emailContact);
}
emailCur.close();
}
if (image_uri != null)
{
System.out.println(Uri.parse(image_uri));
try
{
bitmap = MediaStore.Images.Media
.getBitmap(getActivity().getContentResolver(),
Uri.parse(image_uri));
System.out.println(bitmap);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
mList.add(new Contacts(name, phone, image_uri,emailContact));
ContentValues contentValues = new ContentValues();
contentValues.put("contact_name", name);
contentValues.put("contact_number",phone);
contentValues.put("contact_email",emailContact);
contentValues.put("contact_image",image_uri);
mDb.insert(TABLE_CONTACT, null, contentValues);
emailContact="";
phone="";
}
mDb.setTransactionSuccessful();
mDb.endTransaction();
cur.close();
}

You're querying the CallLog table:
Cursor cur=cr.query(CallLog.Calls.CONTENT_URI,null,CallLog.Calls.DATE, null,null)
and then trying to get info from that cursor with fields from the Contacts table:
cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
Obviously, that's not how it should work.
Also, your selection:
CallLog.Calls.DATE
is not a legal selection string.
How you should do it:
To get a list of starred (favourites) contacts:
String[] projection = new String[] { Contacts._ID }; // you can add more fields you need here
Cursor cursor = cr.query(Contacts.CONTENT_URI, projection, Contacts.STARRED + "=1", null, null);
To get a list of contacts with in the last 24 hours:
String[] projection = new String[] { Contacts._ID }; // you can add more fields you need here
int oneDay = (1000 * 60 * 60 * 24);
long last24h = (System.currentTimeMillis() - oneDay);
Cursor cursor = cr.query(Contacts.CONTENT_URI, projection, Contacts. LAST_TIME_CONTACTED + ">" + last24h, null, null);

I know till now you may have solved that error but still i want to answer for further help for seekers. The code for favorite contact fetching is working you just need to add following in the projection:
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.LOOKUP_KEY,
ContactsContract.Contacts.HAS_PHONE_NUMBER,
ContactsContract.Contacts.DISPLAY_NAME_PRIMARY};

Unable to load contacts

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();

context.getContentResolver().query(ContactsContract.Data.CONTENT_URI, null , null ,null, null);

Hi I am working in Android Contact search module.I am running below Query.
cur = context.getContentResolver().query(ContactsContract.Data.CONTENT_URI, null , null ,null, null);
from this query I am getting Result Multiple times.Is there any thing which I am doing wrong.I want DISTINCT Result Set.
please help me.

I think you mean you got duplicate record for some contacts. So you must add condition for your query
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '"
+ ("1") + "'";
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
cur = context.getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, projection, selection
+ " AND " + ContactsContract.Contacts.HAS_PHONE_NUMBER
+ "=1", null, sortOrder);// this query only return contacts which had phone number and not duplicated

Try this code will help you
public void getContact() {
Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
ContentResolver contect_resolver = getContentResolver();
int size = cur.getCount();
if (size > 0 && cur != null) {
for (int i = 0; i < size; i++) {
cur.moveToPosition(i);
String id = cur.getString(cur.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
String name = "";
Cursor phoneCur = contect_resolver.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
if (phoneCur.moveToFirst()) {
name = phoneCur.getString(phoneCur .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
if (!name.equalsIgnoreCase("")) {
String id1 = phoneCur.getString(phoneCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
Cursor emails = getContentResolver()
.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID
+ " = " + Integer.parseInt(id1),
null, null);
emailAddress="";
if (emails!=null && emails.getCount() > 0) {
emails.moveToFirst();
emailAddress = emails
.getString(emails
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA));
}
emails.close();
contact.setEmail(emailAddress);
id1 = "";
mcontact_arraylist.add(contact);
}
phoneCur.close();
}
}
cur.close();
}
}

Each record should contain a portion of the data for a contact (eg each phone number or address is a separate row) each row has a mimetype associated with it that is used to determine the data stored in each column. So for an address, the "data1" column holds the street data and data4 might hold the state.

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()).
