Android: Contact list has duplicate names

I have a contact list in a sort order. But in my contact list the name is duplicating with same number. I think the issue is because of the contact list sync with different account.
I check with Hash map. But when I using hash map the result is not sorted with name .
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, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE NOCASE ASC");
if (cursor != null) {
try {
int nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
String nameContact = cursor.getString(nameIndex);
finally {
cursor.close();
}
}
Adapter
holder.name.setText(itemListPogo.get(position).getItemName());
Can anyone please help to avoid the duplication in name.

You're seeing duplicate contacts because they belong to different accounts. i.e. Same number can show up 3 times if it is synced with Facebook, WhatsApp, and Google account. You can find more information here Android Account Manager
This is how you can use column ContactsContract.RawContacts.ACCOUNT_TYPE to filter and retrieve contacts associated with a single account only.
String[] projection = new String[] {
ContactsContract.RawContacts._ID,
ContactsContract.RawContacts.ACCOUNT_TYPE,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.PHOTO_URI,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Photo.CONTACT_ID };
String selectionFields = ContactsContract.RawContacts.ACCOUNT_TYPE + " = ?";
String[] selectionArgs = new String[]{"com.google"};
Cursor cursor = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection,
selectionFields,
selectionArgs,
ContactsContract.Contacts.DISPLAY_NAME
);
In this code, only contacts that are associated with Google Account are selected. Similarly, if you want to get list of WhatsApp Contacts only you can replace "com.google" with "com.whatsapp"

I will recommend you to use where my searching ends, it will give you fastest result.
public static List<ContactDTO> getPhone(Context context) {
List<ContactDTO> contactList = new ArrayList<ContactDTO>();
ContentResolver cr = context.getContentResolver();
String[] PROJECTION = new String[] {
ContactsContract.RawContacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.PHOTO_URI,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Photo.CONTACT_ID };
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String filter = ""+ ContactsContract.Contacts.HAS_PHONE_NUMBER + " > 0 and " + Phone.TYPE +"=" + Phone.TYPE_MOBILE;
String order = ContactsContract.Contacts.DISPLAY_NAME + " ASC";// LIMIT " + limit + " offset " + lastId + "";
Cursor phoneCur = cr.query(uri, PROJECTION, filter, null, order);
while(phoneCur.moveToNext()) {
ContactDTO dto = new ContactDTO();
dto.setName("" + phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)));
dto.setMobileNo("" + phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
dto.setPhotoUrl("" + phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI)));
dto.setContactId("" + phoneCur.getString(phoneCur.getColumnIndex(ContactsContract.CommonDataKinds.Photo.CONTACT_ID)));
contactList.add(dto);
}
phoneCur.close();
return contactList;
}
where ContactDTO is Simple POJO class.

I think the issue is because of the contact list sync with different
account.
Yes, your contact list sync many account. You should filter contact with Account type : ContactsContract.CommonDataKinds.Phone.ACCOUNT_TYPE_AND_DATA_SET.
Account you can research in :
https://developer.android.com/reference/android/accounts/AccountManager.html

You can search for the aggregated Contact instead of all RawContacts. This will give you only 1 contact with the given name (like in the Contacts app).
Example (changing your code):
private static final String[] PROJECTION = new String[] {
ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
ContactsContract.Contacts.DISPLAY_NAME_PRIMARY, // Honeycomb+ should use this
ContactsContract.CommonDataKinds.Phone.NUMBER
};
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(
ContactsContract.Contacts.CONTENT_URI,
PROJECTION,
null,
null,
ContactsContract.Contacts.DISPLAY_NAME_PRIMARY + " COLLATE NOCASE ASC");
if (cursor != null) {
try {
int nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME_PRIMARY);
String nameContact = cursor.getString(nameIndex);
finally {
cursor.close();
}
}

Get only numbers shown in the android contactbook

I want to filter what numbers I am getting from Android based on which contacts the user chose to display in his contact book. (For example only contacts saved on the device when all other contacts are excluded)
I read here that you can do this by using
Uri queryUri = ContactsContract.Contacts.CONTENT_URI;
I use following code to read the contacts and I allways get every contact, phone, SIM, etc..
//https://stackoverflow.com/questions/16651609/how-to-display-phone-contacts-only-exclude-sim-contacts
// http://www.higherpass.com/Android/Tutorials/Working-With-Android-Contacts/1/
ContentResolver cr = currentActivity.getContentResolver();
Uri queryUri = ContactsContract.Contacts.CONTENT_URI;
Cursor cur = cr.query(queryUri,
null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) { //Are there still contacts?
//See if the contact has at least one number
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
String id = cur.getString( cur.getColumnIndex(ContactsContract.Contacts._ID) );
String name = cur.getString( cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME) );
ArrayList<String> numbers = new ArrayList<String>();
//Read numbers:
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
numbers.add( pCur.getString(
pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)) );
Log.e("Contactbook", "The latest added number is: " + numbers.get(numbers.size()-1) );
}
pCur.close();
}
}
}
What am I missing? This code still gives me both SIM and phone contacts to the log.
Edit: To clarifify, in the contactbook you got the "Display options". In there ist the "select contacts to display"-option, and I want to read the contacts that are shown based on the users choice there. So if a user choses to show only SIM-contacts, read only SIM-contacts, if he choses to only show Phone-Contacts, show onyl phone contacts etc...

Try with following "selection".
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = ?";
From Android docs:
public static final String IN_VISIBLE_GROUP: An indicator of whether this contact is supposed to be visible in the UI. "1" if the contact has at least one raw contact that belongs to a visible group; "0" otherwise.
This should be your "selection" argument in query API.
Update: I tried below code on Android-2.3(I know it is old device, but right now Don't have newer device with me).
final ContentResolver cr = getContentResolver();
String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME };
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = ?" ;
String[] Args = { "1" };
final Cursor contacts = cr.query(
ContactsContract.Contacts.CONTENT_URI, projection,
selection,Args ,
null);
This could be a long operation (depending on no. of contacts), hence you should use CursorLoader class (A loader that queries the ContentResolver and returns a Cursor) for this.
cursorLoader.loadInBackground();
This will be called on a worker thread to perform the actual load and to return the result of the load operation.

You can easily create two Arrays for each kind of contacts
ArrayList<String> simContacts = new ArrayList<>();
//get all sim contacts
Uri simUri = Uri.parse("content://icc/adn");
Cursor cursorSim = getContext().getContentResolver().query(simUri, null, null, null, null);
while (cursorSim.moveToNext()) {
simContacts.add(cursorSim.getString(cursorSim.getColumnIndex("name")));
}
}
ArrayList<String> allContacts = new ArrayList<>();
//get all contacts
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if (cursor != null && cursor.getCount() > 0) {
while (!cursor.isAfterLast()) {
String phoneNumber = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));
String displayNameColumn = Utils.hasHoneycomb() ? ContactsContract.Contacts.DISPLAY_NAME_PRIMARY : ContactsContract.Contacts.DISPLAY_NAME;
String displayName = cursor.getString(cursor.getColumnIndexOrThrow(displayNameColumn));
//check if simContacts Array contains this particular name
if (!simContacts.contains(displayNameColumn){
allContacts.add(displayNameColumn);
}
}
}
This is just a working example,of course you can modify to your needs.You can parse more contact fields and make more complication queries.

How to actually search for a song in a mediastore cursor using a string

I have set up the cursor but I am still struggling with actually searching it. How do I search for the track name? How do I get its ID so I can pass it to mediaplayer? I have tried different things but didn't succeed.
Basically, I want to know how to search the mediastore for a certain string (string songToPlay in this case), get the results, get the ID of the best match and pass it to my mediaplayer service to play it in the background. The only thing I am asking you is how to get the ID though.
This is the code I am using:
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String[] songToPlay = value.split("play song");
String[] searchWords = songToPlay[1].split(" ");
String [] keywords = null;
StringBuilder where = new StringBuilder();
where.append(MediaStore.Audio.Media.TITLE + " != ''");
String selection = where.toString();
String[] projection = {
BaseColumns._ID,
MediaStore.Audio.Media.MIME_TYPE,
MediaStore.Audio.Artists.ARTIST,
MediaStore.Audio.Albums.ALBUM,
MediaStore.Audio.Media.TITLE
};
for (int i = 0; i < searchWords.length; i++) {
keywords[i] = '%' + MediaStore.Audio.keyFor(searchWords[i]) + '%';
}
Cursor cursor = this.managedQuery(uri, projection, selection, keywords, MediaStore.Audio.Media.TITLE);
if (cursor.moveToFirst()) {
do{
test.setText(cursor.getString(cursor
.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME)));
}while(cursor.moveToNext());
}
I'm very confused and most of this code is from the internet. I have been trying to do this for 2 days now, that's why I'm asking here. I've done hours of trying by myself.
edit: Current code. How am I supposed to find the location - music ID or whatever I need to play that song from the cursor?
Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String songToPlay = value.replaceAll("play song", "").trim();
int music_column_index;
String[] projection = {
MediaStore.Audio.Media._ID,
MediaStore.Audio.Artists.ARTIST,
MediaStore.Audio.Albums.ALBUM,
MediaStore.Audio.Media.TITLE
};
#SuppressWarnings("deprecation")
Cursor cursor = this.managedQuery(uri,
null,
MediaStore.Audio.Media.TITLE + "=?",
new String[]{songToPlay},
MediaStore.Audio.Media.TITLE + " ASC");

This will search the MediaStore for all songs with title equal to the value of your songToPlay string.
Cursor cursor = getContentResolver().query(
MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
null,
MediaStore.Audio.Media.TITLE + "=?",
new String[]{songToPlay},
MediaStore.Audio.Media.TITLE + " ASC");
You can then of course query the cursor to get the ID (and any other column) of any results.
while (cursor.moveToNext()) {
String path = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));
long id = cursor.getLong(cursor.getColumnIndex(MediaStore.Audio.Media._ID));
// Whatever else you need
}
However this will require an exact match, you may like to use the LIKE operator for a more fuzzy match.

Display the Contacts in sorting order ContactsContract.Contacts of Content Resolver

My intention is to display the contacts in sorting order using content resolver in android.
For that I'm writing:
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = ?", new String[] { id }, null);
It needs that the last parameter in query method should not be null for sorting the elements by Name. Which part of code I have to replace the null parameter to achieve sorting by name?

To sort result according to name use Phone.DISPLAY_NAME constant with ASC as last parameter to query method. do it as:
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID+ " = ?",
new String[] { id },
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");

It would be better to use SORT_KEY_PRIMARY or SORT_KEY_ALTERNATIVE on API level 11 and later.
Cursor cursor = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI,
null, null, null,
ContactsContract.Contacts.SORT_KEY_PRIMARY + " ASC");

You can use Upper() to sort for both lower as well as upper case contact name.
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, "upper("+ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + ") ASC");

The ContentResolver.query() method takes many arguments but to sort the content provider records, you have to edit the last argument of this method.
It should be like this:
Cursor cursor=getContentProvider().query(.......,"DISPLAY_NAME ASC")
This will arrange the contacts in Ascending order of their name.
Note: This argument should be in a String datatype.

You can use the Desc string using these lines to sort out to see the recent contact
android.database.Cursor cursor = getContentResolver()
.query(android.provider.ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, null, null,
ContactsContract.Data.CONTACT_LAST_UPDATED_TIMESTAMP +" DESC");

How to fast the contacts loading in listview on android

in my app i am listing contacts in a listview. no of contacts is 1000+. i get the contacts
by using ContentResolver query that is cr.query(...),store the values in an arraylist
and after that load the array list in setListAdapter(...). to display the all contacts my
apps takes nearly 1 minute so that i use Async task but there is no big differences by using the async task.
i need to display all contacts within 2 to 4 seconds. i check in the default contacts
application on android simulator which is load within in 2 to 4 seconds. i have spend
long time in google. but i could not get any helpful solution. please help me how to fast the loading contacts on listview. please help me.
my coding sample:
private ArrayList<ContactListEntry> loadContactListInternal(String searchString) {
ArrayList<ContactListEntry> contactList = new ArrayList<ContactListEntry>();
ContentResolver cr = getContentResolver();
Cursor cur = null;
String[] projection = new String[] {BaseColumns._ID,ContactsContract.Contacts.DISPLAY_NAME,ContactsContract.Contacts.PHOTO_ID};
....
cur=cr.query(ContactsContract.Contacts.CONTENT_URI, projection, selection, null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
while (cur.moveToNext()) {
int id = Integer.parseInt(cur.getString(0));
....
if (input !=null)
photo = BitmapFactory.decodeStream(input);
....
ArrayList<ContactListEntry.PhoneEntry> phoneEntries = new ArrayList<ContactListEntry.PhoneEntry>();
String[] projection1 = new String[] {ContactsContract.CommonDataKinds.Phone.NUMBER,ContactsContract.CommonDataKinds.Phone.TYPE};
Cursor pcur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,projection1, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { String.valueOf(id) }, null);
while (pcur.moveToNext()) {
...
}
pcur.close();
ContactListEntry entry = new ContactListEntry(id, name, photo, phoneEntries);
contactList.add(entry);
}
cur.close();
return contactList;
}
.....
in another class
private void selectionUpdated() {
....
setListAdapter(new SelectedArrayAdapter(this, app.selectedContacts));
...
}

Use the Concept of projections and selection arguments to retrive the contacts in my case for 500 contacts intially it was taking 12 sec.
Now it is taking 350ms(lessthan second)
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");
}

So your problem is that you do a lot of subqueries for each contact. I has the same issue once upon a time. My case was that I showed many contacts and allowed the user to click on any of them. After that I started processing the contact in another activity.
Back then I finally decided that I should display only the name and lazily fetch all the other data later on, just before I launch the next activity. This was amazing: decreased the speed of my program almost by a factor of 200, and the operations became completely invisible to the user.
The default android list does the same if I am not wrong - it displays only the name, and later on loads all the other contact-related data.

i use cursor adapter and i cut the databse,arrayadapter and optimize the code.

Consider having just one query and getting rid of the sub query idea (as already suggested). You can achieve speed by just querying using the Content Uri:
"ContactsContract.CommonDataKinds.Phone.CONTENT_URI"
This URI also has the "ContactsContract.Contacts.DISPLAY_NAME" field.
You might also want to consider doing this query and working with your adapter in a seperate thread to make it completely transparent.
This worked for me.

OPTIMIZED 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...:)
