All Contacts are not showing while retrieving contacts

I implemented a code to retrieve all contacts but it is not showing all contacts where few of them are missed.
Here is my code:
String[] projection = new String[]{
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER,
};
Cursor cursor = null;
try {
cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection, null, null, null);
} catch (SecurityException e) {
}
if (cursor != null) {
try {
HashSet<String> normalizedNumbersAlreadyFound = new HashSet<>();
int indexOfNormalizedNumber = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER);
int indexOfDisplayName = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
int indexOfDisplayNumber = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
while (cursor.moveToNext()) {
String normalizedNumber = cursor.getString(indexOfNormalizedNumber);
if (normalizedNumbersAlreadyFound.add(normalizedNumber)) {
String displayName = cursor.getString(indexOfDisplayName);
String displayNumber = cursor.getString(indexOfDisplayNumber);
listOfContacts.add(new PhoneContactsModel(displayName, displayNumber, false));
} else {
}
}
Log.d("tag", "size of listOfContacts =1====" + listOfContacts.size());
} finally {
cursor.close();
}
}
don't know what is happening. Please help me.

There are many issues in the code:
You're querying over the CommonDataKinds.Phone.CONTENT_URI table, so naturally, you won't get contacts that have no phone numbers (e.g. contacts with name and email)
You're skipping contacts that contains phones you've already encountered in normalizedNumbersAlreadyFound, so if you have two contacts with a shared phone (like a home phone number) you might skip one of them.
CommonDataKinds.Phone.NORMALIZED_NUMBER may be null, in which case you'll skip many contacts that do not have their NORMALIZED_NUMBER field set
If you need to also include contacts that have no phones, I would recommend a completely different code. If you only need to get contacts with phones, I would recommend not relying on NORMALIZED_NUMBER, and instead add CommonDataKinds.Phone.CONTACT_ID to your projection, and have that as your unique key per contact.

Check Incoming number is stored in Contacts list or not android

In my android app when an incoming call i want to show my custom ui and i am able to do this.
No i want to check incoming number is from contacts or not.
Below is my code for doing so but it returns null for an incoming number which is stored in my contacts list.
public String findNameByNumber(String num){
Uri uri = Uri.withAppendedPath(Phones.CONTENT_FILTER_URL, Uri.encode(num));
String name = null;
Cursor cursor = mContext.getContentResolver().query(uri,
new String[] { Phones.DISPLAY_NAME }, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
name = cursor.getString(cursor.getColumnIndex(Phones.DISPLAY_NAME));
cursor.close();
callyName.setText(name+" Calling..");
}
return name;
}
and i have incoming call from a number say+917878787878 but in my contacts this contact is stored as name XYZ with number 78 78 787878,which is formated because between number there are space.and also try by excluding +91 but still it returns null.
So how can i find number which is stored in any format.Which may be stored with country code or not.
Thanks In advance.

Try this code instead (using PhoneLookup.CONTENT_FILTER_URI instead of Phones):
String res = null;
try {
ContentResolver resolver = ctx.getContentResolver();
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Cursor c = resolver.query(uri, new String[]{PhoneLookup.DISPLAY_NAME}, null, null, null);
if (c != null) { // cursor not null means number is found contactsTable
if (c.moveToFirst()) { // so now find the contact Name
res = c.getString(c.getColumnIndex(CommonDataKinds.Phone.DISPLAY_NAME));
}
c.close();
}
} catch (Exception ex) {
/* Ignore */
}
return res;
As docs says ContactsContract.PhoneLookup: A table that represents the result of looking up a phone number, for example for caller ID. To perform a lookup you must append the number you want to find to CONTENT_FILTER_URI. This query is highly optimized.

How to obtain the contact Uri directly with contact creation

my app creates new contacts with ContentProviderOperation. The problem is, I need a reference to the new contact because I need some information of it to display it in a listview and go with intent into the contact app to the contact.
The best thing would be the ID, but I´ve read that it might change during operations on the database, which won´t be helpful to me.
Now I thought, the Uri might be the best thing, because I could later retrieve the contactID or lookup key.
How do I get the Uri directly after calling applyBatch() ?
EDIT:
Here is a solution, but not really a good one.
He is putting a randomly generated token into each contact, then he makes a new query with it.
I want neither put some extra data into the contacts, nor starting a second query. But if there is no other possibility I´ll do it that way.

simply call
private String retrieveContactId(String phoneNo) {
try {
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNo));
String[] projection = new String[] { ContactsContract.PhoneLookup._ID, ContactsContract.PhoneLookup.DISPLAY_NAME };
String selection = null;
String[] selectionArgs = null;
String sortOrder = ContactsContract.PhoneLookup.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
ContentResolver cr = getApplicationContext().getApplicationContext().getContentResolver();
String contactId = null;
if (cr != null) {
Cursor resultCur = cr.query(uri, projection, selection, selectionArgs, sortOrder);
if (resultCur != null) {
while (resultCur.moveToNext()) {
contactId = resultCur.getString(resultCur.getColumnIndex(ContactsContract.PhoneLookup._ID));
Log.e("Info Incoming", "Contact Id : " + contactId);
return contactId;
}
resultCur.close();
}
}
} catch (Exception sfg) {
Log.e("Error", "Error in loadContactRecord : " + sfg.toString());
}
return null;
}
and for the uri
Uri contactUri = Contacts.getLookupUri(
Integer.valueOf(rawContactId), clookup);

Android getting contact phone image

Hey all i have a programmer thats having some trouble with getting my phone image to display in an app. the following code is what he is using to get the contact picture:
private long getContactIdFromNumber(String number) {
Cursor c = null;
try {
String[] projection = new String[] { Contacts.Phones.PERSON_ID };
Uri contactUri = Uri.withAppendedPath(
Contacts.Phones.CONTENT_FILTER_URL, Uri.encode(number));
c = getContentResolver().query(contactUri, projection, null, null,
null);
if (c.moveToFirst()) {
long contactId = c.getLong(c
.getColumnIndex(Contacts.Phones.PERSON_ID));
return contactId;
}
} finally {
c.close();
}
return -1;
}
private boolean initPhoto() {
boolean result = true;
try {
contactPhoto = People.loadContactPhoto(getApplicationContext(),
ContentUris.withAppendedId(People.CONTENT_URI,
getContactIdFromNumber(phoneNumber)),
R.drawable.header, null);
} catch (Exception e) {
result = false;
}
return result;
}
if (initPhoto()) {
contact1.setImageBitmap(contactPhoto);
contact2.setImageBitmap(contactPhoto);
contact3.setImageBitmap(contactPhoto);
}
I made a contact with my phone number and image but it never loads up in the app. What should he be looking for in the code i posted above in order to make sure it is grabbing the correct phone number?

Do you have to use Contacts instead of ContactsContract? Contacts was deprecated in API level 5.
If you're trying to load a photo for a phone number, use ContactsContract.PhoneLookup. There's an example in the reference doc for android.provider.ContactsContract.PhoneLookup. Querying on that table will return LOOKUP_KEY for the Contact. Use that to query
ContactsContract.Contacts.Photo.

Turned out the number was formatted incorrectly. It was looking for xxxxxxxxxx and the number was this way (xxx)xxx-xxxx in the phone so it never matched up.

Android: strange thing about loading contact info

I created an app. It is working on htc desire hd, but when i tested it on ZTE Blade, a strange problem appeared. In my app when user selects a contact name from a spinner a menu appears. In the menu the user can send sms to the user, call him/her or just look at his/her contact info. On HTC Desire HD, everything is working fine. On ZTE there seems to be an exasperating problem with the contact info button: In certain cases when user selects a contact and wants to see his contact info, some other contact's info is shown. So I select Pete from my spinner but I get Dave's contact info. In other cases I select Tom from the spinner and I get Tom's contact info. The problem is not existing on my HTC. I couldn't figure out what causes the problem. By the way, my contact list on HTC is populated also from gmail and facebook and the app still working fine, while the contact list of the ZTE has never seen any gmail or facebook accounts (i am not entirely sure about this).
This is the code i am using to get to the contact info:
infobtn.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0)
{
while (cur.moveToNext()) {
id_contact = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
name_contact = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (name_contact.equals(name1))
{
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", new String[]{id_contact}, null);
id_contact2 = id_contact;
while (pCur.moveToNext()){
}
pCur.close();
}
}
Intent intent_contacts = new Intent(Intent.ACTION_VIEW, Uri.parse("content://contacts/people/" + id_contact2));
startActivity(intent_contacts);
}
}
});

I have similar problems in my application. The app is a widget that give possibility to use favorites contacts in fast way. User creates new widget and assigns contact to it. When he clicks on widget he is able to make common contact actions - call, sms, edit, etc.
Some users send report like this one:
"I select about 4 contacts and the app shows 4 but only one of them right 3 others is same contact which I didnt even picked".
"Why does the wrong contact show when picked? On my droid incredible"
I can't reproduce the problem on my side. I have tried several different devices, tried to make import/export contacts - no results.
Anyway, i have some ideas about source of the problem.
My application uses lookup keys to store contacts, according to sdk. So, when user picks up a contact, application stores contact lookup key. Then it uses this lookup key to get Contact ID for this contact. After that, it uses ONLY received Contact ID in all other functions. So does your function - it uses only Contact ID in sub-query.
The question is: is it possible that different contacts (with different lookup keys) have same Contact ID? It looks like it's possible on some devices in rare cases... If so, we need to use Contact ID + lookup key always together to identify contact. (update: the suggestion was incorrect. Lookup key can be changed after contact info modification, you won't find contact).
As I understand, you are able to reproduce the problem on your side. I would suggest to change your code in such way:
infobtn.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0)
{
while (cur.moveToNext()) {
id_contact = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
name_contact = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String lookup_key = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
if (name_contact.equals(name1))
{
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ? AND " + ContactsContract.CommonDataKinds.Phone.LOOKUP_KEY + " = ?", new String[]{id_contact, lookup_key}, null);
id_contact2 = id_contact;
while (pCur.moveToNext()){
}
pCur.close();
}
}
Intent intent_contacts = new Intent(Intent.ACTION_VIEW, Uri.parse("content://contacts/people/" + id_contact2));
startActivity(intent_contacts);
}
}
});
and try to reproduce the problem again.

You can see this link, It's very good: http://www.vtutorials.info/2014/08/working-with-android-contacts-how-to.html
private Map<Long, ArrayList<LocalContactInfo>> queryAllPhones(ContentResolver contentresolver)
{
HashMap<Long, ArrayList<LocalContactInfo>> hashmap = new HashMap<Long, ArrayList<LocalContactInfo>>();
Uri PhoneCONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String Phone_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;
String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;
Cursor cursor = contentresolver.query(PhoneCONTENT_URI, null, null, null, null);
do
{
if (!cursor.moveToNext())
{
cursor.close();
return hashmap;
}
long l = cursor.getLong(cursor.getColumnIndex(Phone_CONTACT_ID));
String s = cursor.getString(cursor.getColumnIndex(NUMBER));
LocalContactInfo temp = new LocalContactInfo(String.valueOf(l), "", s, "", 1);
if (hashmap.containsKey(Long.valueOf(l))){
((List<LocalContactInfo>)hashmap.get(Long.valueOf(l))).add(temp);
} else{
ArrayList<LocalContactInfo> arraylist = new ArrayList<LocalContactInfo>();
arraylist.add(temp);
hashmap.put(Long.valueOf(l), arraylist);
}
} while (true);
}
And:
public List<LocalContactInfo> doloadContacts() {
List<LocalContactInfo> _return = new ArrayList<LocalContactInfo>();
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;
ContentResolver contentResolver = mContext.getContentResolver();
Map<Long, ArrayList<LocalContactInfo>> map = queryAllPhones(contentResolver);
Cursor cursor = contentResolver.query(CONTENT_URI, null,null, null, null);
if(cursor == null || cursor.getCount()==0){
return _return;
}
if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
Long contact_id = cursor.getLong(cursor.getColumnIndex( _ID ));
String fullname = cursor.getString(cursor.getColumnIndex( DISPLAY_NAME )).trim();
int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex( HAS_PHONE_NUMBER )));
if (hasPhoneNumber > 0 && map.get(contact_id) != null){
Object obj = ((List<LocalContactInfo>)map.get(contact_id)).get(0);
if(obj instanceof LocalContactInfo){
LocalContactInfo _temp = (LocalContactInfo)obj;
_return.add(new LocalContactInfo(String.valueOf(contact_id), fullname, _temp.getNumberPhone(), "",hasPhoneNumber));
}
}
}
}
return _return;
}

instead of using "contacts/people/xxx", try using contactsContract.Contacts.CONTENT_URI.
basically, you want to replace.
Uri contactUri = Uri.parse("content://contacts/people/" + id_contact2));
with
Uri contactUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI,
id_contact2);
Another thing to note is that "id_contact2" may be changed if a sync occurs before you use it (like when google sync merges a contact). To prevent this, it might be better to use a LookupKey instead.
ContactsContract.Contacts.LOOKUP_KEY
and retrieve using
Uri contactUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI,
yourContactLookupKey);
