How to remove duplicate contact number from all type of contact without database?

How to remove duplicate number entry in Android when fetching contact number from contact book?
For example:
In contact book for
one name multiple contact.. ex-type-home-9428060123,
type-work-9428060123, I want to fetch unique contact number from all
type,android problematically? I use below code for fetching
information:
private void getContactsDetails() {
showLoader();
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '"
+ ("1") + "'";
Cursor phones = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, null/*selection + " AND " +
ContactsContract.Contacts.HAS_PHONE_NUMBER + "=1"*/, null, "UPPER("
+ ContactsContract.Contacts.DISPLAY_NAME + ") ASC");
ContactString = new ArrayList<>();
if (phones != null) {
if (phones.getCount() > 0) {
tvNoContact.setVisibility(View.GONE);
while (phones.moveToNext()) {
String Name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
HashSet<String> mobileNoSet = new HashSet<String>();
if (!mobileNoSet.contains(number)){
String s = number.replaceAll("\\W", "");
String lastTenCharContact = null;
if (s != null && s.length() > 10) {
lastTenCharContact = s.substring(s.length() - 10);
} else {
lastTenCharContact = s;
}
// String substring = s.substring(Math.max(s.length() - 10, 0));
Log.d(TAG, "getContactsDetails: " + lastTenCharContact);
String image_uri = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
ContactString.add(lastTenCharContact);
DeviceContact contactModel = new DeviceContact(Name.toUpperCase(), lastTenCharContact, image_uri);
contactModelsList.add(contactModel);
mobileNoSet.add(number);
Log.d(TAG, "Name : " + Name + ", Number : " + number + ", Photo : " + image_uri);}
}
hideLoader();
AllContactsyncapiCall();
} else {
tvNoContact.setVisibility(View.VISIBLE);
}
} }

for remove duplicate Number just make hashset before your loop:
HashSet<String> mobileNoSet = new HashSet<String>();
Now when you put contact in model use below code:
if (!mobileNoSet.contains(number)){
String s = number.replaceAll("\\W", "");
String lastTenCharContact = null;
if (s != null && s.length() > 10) {
lastTenCharContact = s.substring(s.length() - 10);
} else {
lastTenCharContact = s;
}
// String substring = s.substring(Math.max(s.length() - 10, 0));
Log.d(TAG, "getContactsDetails: " + lastTenCharContact);
String image_uri = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
ContactString.add(lastTenCharContact);
DeviceContact contactModel = new DeviceContact(Name.toUpperCase(), lastTenCharContact, image_uri);
contactModelsList.add(contactModel);
mobileNoSet.add(number);
}

This is new code in which i m getting duplicate number :-
private void getContactsDetails() {
// showLoader();
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null/*selection + " AND " + ContactsContract.Contacts.HAS_PHONE_NUMBER + "=1"*/, null, "UPPER(" + ContactsContract.Contacts.DISPLAY_NAME + ") ASC");
ContactString = new ArrayList<>();
nameString = new ArrayList<>();
if (phones != null) {
if (phones.getCount() > 0) {
tvNoContact.setVisibility(View.GONE);
HashSet<String> mobileNoSet = new HashSet<String>();
while (phones.moveToNext()) {
String Name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
if (!mobileNoSet.contains(number)) {
// String s = number.replaceAll("\\W", "");
String s = number.replaceAll("[^[+]\\d]", "");
String lastTenCharContact = null;
lastTenCharContact = s;
/*if (s != null && s.length() > 10) {
lastTenCharContact = s.substring(s.length() - 10);
} else {
lastTenCharContact = s;
}*/
// String substring = s.substring(Math.max(s.length() - 10, 0));
Log.d(TAG, "getContactsDetails: " + lastTenCharContact);
String image_uri = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
ContactString.add(lastTenCharContact);
// nameString.add(Name);
contactModel = new DeviceContact(Name.toUpperCase(), lastTenCharContact, image_uri);
contactModelsList.add(contactModel);
mobileNoSet.add(number);
Log.d(TAG, "Name : " + Name + ", Number : " + number + ", Photo : " + image_uri);
}
}
// hideLoader();
AllContactsyncapiCall();
} else {
tvNoContact.setVisibility(View.VISIBLE);
}
}
}

Getting specific contact information

I'm trying to get the given name, family name etc of a specific contact on android but can't seem to be able to. I've been banging my head on this for hours, basically if (nameCur.moveNext()) is always false! This code is originally by #perborin (How to get the first name and last name from Android contacts?). Please help!
P.S. I've added <uses-permission android:name="android.permission.READ_CONTACTS"/> in the AndroidManifest, so that is not the problem.
// A contact ID is fetched from ContactList
Uri resultUri = data.getData();
Cursor cont = getContentResolver().query(resultUri, null, null, null, null);
if (!cont.moveToNext()) {
Toast.makeText(this, "Cursor contains no data", Toast.LENGTH_LONG).show();
return;
}
int columnIndexForId = cont.getColumnIndex(ContactsContract.Contacts._ID);
String contactId = cont.getString(columnIndexForId);
// Fetch contact name with a specific ID
String whereName = ContactsContract.Data.MIMETYPE + " = ? AND " + ContactsContract.CommonDataKinds.StructuredName.CONTACT_ID + " = " + contactId;
String[] whereNameParams = new String[] { ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE };
Cursor nameCur = getContentResolver().query(ContactsContract.Data.CONTENT_URI, null, whereName, whereNameParams, ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME);
while (nameCur.moveToNext()) {
String given = nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME));
String family = nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.FAMILY_NAME));
String display = nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME));
Toast.makeText(this, "Name: " + given + " Family: " + family + " Displayname: " + display, Toast.LENGTH_LONG).show();
}
nameCur.close();
cont.close();

Solved by referring to user3717188 answer at Get first and last name of a contact rather than single display name?.
Cursor phone_cursor = cr.query(ContactsContract.CommonDataKinds.
Phone.CONTENT_URI, null, null, null, null);

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 sqlite select statement does not work well

I've got three table and i want make a query withe sql statement, but it does not work well because it does not give me all the possible results...
The code:
public void setsuchresultat(String pSearchword)
{
String[] table = new String[]{"tbl_A", "tbl_B", "tbl_C"};
String[] column = new String[]{"columnA", "columnB" }; // Type varchar(50) not null
String[] search = new String[]{"%" + pSearchword+ "%", pSearchword+ "%", "%" + pSearchword, pSearchword};
getdata(table,column,search);
}
public void getdata(String[] pTable, String[] pColumn, String[] pSearch)
{
for(String t:pTable)
{
for(String s : pColumn)
{
for(String k : pSearch)
{
Cursor c = this.db.rawQuery("SELECT * FROM " + t + " WHERE " + s + " LIKE '"+ k + "'", null);
if ((c.moveToFirst()) || c.getCount() > 0)
{
while(c.moveToNext())// Suchresultat abspeichern
{
String col1 = c.getString(c.getColumnIndex("columnA"));
String col2 = c.getString(c.getColumnIndex("columnB"));
}
}
}
}
}
}

I think problem is in your loop and if check.
Change
if ((c.moveToFirst()) || c.getCount() > 0)
{
while(c.moveToNext())// Suchresultat abspeichern
{
String col1 = c.getString(c.getColumnIndex("columnA"));
String col2 = c.getString(c.getColumnIndex("columnB"));
}
}
to
if (c.moveToFirst() || c.getCount() > 0) /* OR if (c != null && c.moveToFirst())*/ {
do {
String col1 = c.getString(c.getColumnIndex("columnA"));
String col2 = c.getString(c.getColumnIndex("columnB"));
} while(c.moveToNext());
}

Fetch contact list along with their primary email and phone number in a single query from the ContactProvider

I am trying to get the list of contacts with their phone and email details to display them in a list. What i have done now is do three separate queries.
Get list of contacts to contactCursor from Contacts.CONTENT_URI
Get all phone numbers to phoneCursor from Phone.CONTENT_ITEM_TYPE
Get all emails to emailCursor from Email.CONTENT_ITEM_TYPE
Then i will am Looping through the contactCursor. For every contact, i will loop through the phoneCursor and emailCursor to get the primary phone number and email. But this takes some time to load and is clearly visible when the number of contacts is large. Is there any way that i can get all these details in the first step itself.
Below is the code snippet:
Cursor contacts = resolver.query(Contacts.CONTENT_URI,
CONTACT_PROJECTION, Contacts.HAS_PHONE_NUMBER + " != 0", null, Contacts._ID + " ASC");
Cursor phone = resolver.query(Data.CONTENT_URI, PHONE_PROJECTION,
Data.MIMETYPE + "=? ",
new String[]{Phone.CONTENT_ITEM_TYPE},
Data.CONTACT_ID + " ASC");
Cursor email = resolver.query(Data.CONTENT_URI, EMAIL_PROJECTION,
Data.MIMETYPE + "=? ",
new String[]{Email.CONTENT_ITEM_TYPE},
Data.CONTACT_ID + " ASC");
if (contacts!=null && contacts.moveToFirst()) {
do {
String contactId = contacts.getString(0);
if(phone!=null && phone.moveToFirst()){
do{
if(contactId.equalsIgnoreCase(phone.getString(0))){
contact.setMobile(phone.getString(1));
break;
}
}while(phone.moveToNext());
}
if(email!=null && email.moveToFirst()){
do{
if(contactId.equalsIgnoreCase(email.getString(2))){
contact.setEmailWork(email.getString(1));
break;
}
}while(email.moveToNext());
}
} while (contacts.moveToNext());

Below is the code to fetch all the contacts including email.
private void getContacts() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
String id = null, name = null, email = null, phone = null, note = null, orgName = null, title = null;

int size = cur.getCount();

name = "";
cnt++;
id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (name != null && name != "") {
