Contact Ids are missing when querying to raw contacts table according to account name

I am unable to get all contact ids from the RawContacts table
private void displayAllContactsByType(String accountName)

rawCursor.moveToFirst();
int contactIdColumn = rawCursor.getColumnIndex(ContactsContract.RawContacts.CONTACT_ID);
int rawCursorCount = rawCursor.getCount();
int total = 1;
Utils.Log("Raw Size", " " + rawCursorCount);//rawCursorCount is correct here
while (rawCursor.moveToNext()) {
Long contactId = rawCursor.getLong(contactIdColumn);
publishProgress(((total * 100) / rawCursorCount));
progressBar.setProgressNumberFormat("" + total + "/" + rawCursorCount);
storeContactDetails(contactId, accountName);
++total;
//I am facing problem in this method only below code is just for understanding.
}
}
Contact ids are passed to the below method with account name to get the contact details from respective id but contact ids are less compare to the log //Utils.Log("Raw Size", " " + rawCursorCount).

please help me to solve this case or suggest any other ways to get the contact_ids . Thanks in Advance.

The problem is that you are loosing the first contact you fetch from the db.
The statement rawCursor.moveToFirst(); positions the cursor on the first available result record. The, when you want to iterate over the results, you call rawCursor.moveToNext() inside your loop. The loop condition is executed before it's body, so, you end up moving the cursor to the second row, loosing the first record.
You can fix this by getting rid of rawCursor.moveToFirst().

How to edit existing Contacts in Android?

I am trying to edit existing phone contacts by using application. By using contact name am getting the corresponding contact id.Then am trying to update the existing contacts by using the contact id. But unfortunately it is not updating.
My code is as follows,
String select = "(" + ContactsContract.Contacts.DISPLAY_NAME + " == \"" + edt_nameDetail.getText() + "\" )";
Cursor c = getActivity().getApplicationContext().getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, CONTACTS_SUMMARY_PROJECTION, select, null, ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC");
getActivity().startManagingCursor(c);
if (c.moveToNext()) {
ContactId = c.getString(0);
Log.e("Tag contact id ","edit contact id "+ ContactId);
}
try
{
String name = edt_nameDetail.getText().toString().trim();
String email = edt_contactEmailDetail.getText().toString().trim();
String number = edt_mobileNumberDetail.getText().toString().trim();
ContentResolver contentResolver = getActivity().getContentResolver();
String where = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] emailParams = new String[]{ContactId, ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE};
String[] nameParams = new String[]{ContactId, ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE};
String[] numberParams = new String[]{ContactId, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE};
ArrayList<android.content.ContentProviderOperation> ops = new ArrayList<android.content.ContentProviderOperation>();
if(!email.equals("") &&!name.equals("")&& !number.equals(""))
{
ops.add(android.content.ContentProviderOperation.newUpdate(android.provider.ContactsContract.Data.CONTENT_URI)
.withSelection(where,emailParams)
.withValue(ContactsContract.CommonDataKinds.Email.DATA, email)
.build());
ops.add(android.content.ContentProviderOperation.newUpdate(android.provider.ContactsContract.Data.CONTENT_URI)
.withSelection(where,nameParams)
.withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME, name)
.build());
ops.add(android.content.ContentProviderOperation.newUpdate(android.provider.ContactsContract.Data.CONTENT_URI)
.withSelection(where,numberParams)
.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, number)
.build());
contentResolver.applyBatch(ContactsContract.AUTHORITY, ops);
Toast.makeText(getActivity(), "Contact is successfully edited", Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(getActivity(), "Fail edit", Toast.LENGTH_SHORT).show();
}

If you are searching with email then update your .withSelection as
.withSelection(ContactsContract.CommonDataKinds.Email.ADDRESS + "=? AND " +
Data.MIMETYPE + "='" +
ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE + "'",
new String[]{email})
update all your withselection code corresponding to your search type

Note: after this, contact ID will changed.
public static boolean updateContactName(String contactId, String pre, String first, String mid, String last, String suf)
{
try
{
if (pre == null && first == null && mid == null && last == null && suf == null)
return false;
String where = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] nameParams = new String[]{contactId, ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE};
ArrayList<android.content.ContentProviderOperation> ops = new ArrayList<>();
android.content.ContentProviderOperation.Builder t ;
android.content.ContentProviderOperation b ;
t = android.content.ContentProviderOperation.newUpdate(Data.CONTENT_URI);
t = t.withSelection(where, nameParams);
if(pre != null)
t = t.withValue(StructuredName.PREFIX, pre.trim());
if(first != null)
t = t.withValue(StructuredName.GIVEN_NAME, first.trim());
if(mid != null)
t = t.withValue(StructuredName.MIDDLE_NAME, mid.trim());
if(last != null)
t = t.withValue(StructuredName.FAMILY_NAME, last.trim());
if(suf != null)
t = t.withValue(StructuredName.SUFFIX, suf.trim());
b = t.build();
ops.add(b);
ContentManager.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
return true;
}
catch (Exception e) {}
return false;
}

Android updating wrong contacts

I'm trying to make my app update some contacts but it's updating the wrong people. I get the contact Name, Number and Raw Id. Then if it is true to my if I change his number and update it by his Raw ID. That's my code:
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
while (phones.moveToNext())
{
String numero;
String fnum;
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
int id = phones.getInt(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.RAW_CONTACT_ID));
String tipo = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
phoneNumber = phoneNumber.replace(" ", "");
phoneNumber = phoneNumber.replace("-", "");
phoneNumber = phoneNumber.replace("+", "");
phoneNumber = phoneNumber.replace("*", "");
phoneNumber = phoneNumber.replace("#", "");
int tamanho = phoneNumber.length();
numero = phoneNumber;
if (tamanho == 12) {
if (checar.indexOf(numero.substring(1, 3) + ",") != -1) {
if(numero.substring(3).startsWith("9")){
fnum = numero.substring(0, 3) + "" + numero.substring(4);
update(id, fnum, tipo);
}
}
}
Thread.sleep(2000);
}
phones.close();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
And that's the update method:
public void update(int id, String number, String tipo)
{
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
// Number
builder = ContentProviderOperation.newUpdate(ContactsContract.Data.CONTENT_URI);
builder.withSelection(ContactsContract.Data.CONTACT_ID + "=?" + " AND " + ContactsContract.Data.MIMETYPE + "=?"+ " AND " + ContactsContract.CommonDataKinds.Organization.TYPE + "=?", new String[]{String.valueOf(id), ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE, tipo});
builder.withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, number);
ops.add(builder.build());
// Update
try
{
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
}
catch (Exception e)
{
e.printStackTrace();
}
}
What am I doing wrong?

I think that what's wrong is that you're retrieving RAW_CONTACT_ID when you get the number, but in update() you're passing this value to the column CONTACT_ID. The first one points to raw contacts, but the second one points to the Contacts table. Don't mix them!
I also notice that you're trying to update the ORGANIZATION column with the value of Phone.TYPE, which may or may not work.

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) {

//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);
}

//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);
}

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...

How to Contacts App on Android?

Im using Android 2.1 Api
I need to add a String MIME type into existing contacts for storing a userdefined data apart from Phone numbers,email etc.Please help me how to add that Custom Field from my application.
I request with an example because I am a week old on Android.

Here is an example that saves a boolean as my custom mime type to the contacts. It uses the latest SDK 2.1
public static final String MIMETYPE_FORMALITY = "vnd.android.cursor.item/useformality";
public clsMyClass saveFormality() {
try {
ContentValues values = new ContentValues();
values.put(Data.DATA1, this.getFormality() ? "1" : "0");
int mod = ctx.getContentResolver().update(
Data.CONTENT_URI,
values,
Data.CONTACT_ID + "=" + this.getId() + " AND "
+ Data.MIMETYPE + "= '"
+ clsContacts.FORMALITY_MIMETYPE + "'", null);
if (mod == 0) {
values.put(Data.CONTACT_ID, this.getId());
values.put(Data.MIMETYPE, clsContacts.FORMALITY_MIMETYPE);
ctx.getContentResolver().insert(Data.CONTENT_URI, values);
}
} catch (Exception e) {
Log.v(TAG(), "saveFormality failed");
}
return this;
}
public boolean getFormality() {
if (data.containsKey(FORMALITY)) {
return data.getAsBoolean(FORMALITY);
} else {
// read formality
Cursor c = readDataWithMimeType(clsContacts.MIMETYPE_FORMALITY, this.getId());
if (c != null) {
try {
if (c.moveToFirst()) {
this.setFormality(c.getInt(0) == 1);
return (c.getInt(0) == 1);
}
} finally {
c.close();
}
}
return false;
}
}
public clsMyClass setFormality(Boolean value) {
data.remove(FORMALITY);
data.put(FORMALITY, value);
return this;
}
/**
* Utility method to read data with mime type
*
* #param mimetype String representation of the mimetype used for this type
* of data
* #param contactid String representation of the contact id
* #return
*/
private Cursor readDataWithMimeType(String mimetype, String contactid) {
return ctx.getContentResolver().query(
Data.CONTENT_URI,
new String[] {
Data.DATA1
},
Data.RAW_CONTACT_ID + "=" + contactid + " AND " + Data.MIMETYPE + "= '" + mimetype
+ "'", null, null);
}
Usage is
objContact.setFormality(true).saveFormality();
