Android native contact modification

I'm new to android and i'm working with native contact.
So my app is let user put contact display name and their number for edit/delete.
In case the contact have more that one number.
I tried a lot but still have no luck, the app still doesn't update the number or it crashes.
What I'm going to do as my understanding is:
Find name in contact that matched name user inserted and use that to get contact_id that represent this contact datagroup.
Use contact_id in 1. and the number user input to find ._ID that represent the specific row id.
Do task with ._ID we get from 2.
This is 1. code to get contact_id:
public String getPeopleUniqueID(String name, Context context) {
String s = null;
String selection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" like'%" + name +"%'";
String[] projection = new String[] {ContactsContract.Data.CONTACT_ID};
Cursor c = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection, selection, null, null);
if(c.moveToFirst()) {
s = c.getString(c.getColumnIndex(ContactsContract.Data.CONTACT_ID));
}
c.close();
return s;
}
This is 2. code to get ._ID (num is number user inserted and name is from 1. > the contact_id)
public String checkPhoneNumber(String num, String name, Context context) {
String s = null;
String selection = ContactsContract.CommonDataKinds.Phone.NUMBER + "=?" + " AND "+ContactsContract.Data.CONTACT_ID+ "=?";
String[] projection = new String[] {ContactsContract.Data._ID};
Cursor c = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection, selection, new String[]{u,name}, null);
if(c.moveToFirst()) {
s=c.getString(c.getColumnIndex(ContactsContract.Data._ID));
}
c.close();
if (s==null){
s = "null";
}
return s;
}
To do something like editing (num is _.ID we get from 2. and newnum is new number user want to change into).
public void editNumber(String num , String newnum) {
ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI)
.withSelection(Data._ID + "=? AND " +
Data.MIMETYPE + "='" +
CommonDataKinds.Phone.CONTENT_ITEM_TYPE + "'",
new String[]{num})
.withValue(Data.DATA1, newnum)
.build());
try{
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);}
catch (RemoteException e){e.printStackTrace();}catch (OperationApplicationException e) {e.printStackTrace();}
}
And well it crashes when I call editNumber().
Can you help me fix my code and my understanding?
And another question, can I edit/insert group for the contact programatically, like I want to add this contact to family friend or co-worker group (the default group that we can set at contact edit page)?

Use ContactsContract.Contacts.CONTENT_FILTER_URI for searching a contact based on name - to get Id or anything else. The like operator cannot handle all cases which the CONTENT_FILTER_URI does handle - For various languages, special characters etc.
http://developer.android.com/reference/android/provider/ContactsContract.Contacts.html#CONTENT_FILTER_URI
Use following uri to lookup a contact from phone number - you can get person id or anything else :
Uri lookupUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,
Uri.encode(phoneNumber));
In the set query you can also use contactId in the condition
For groups you can use custom mimetypes if the default one does not suit you (which is still very primitive for groups across different account types)

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 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...:)

Can't fetch phone numbers for linked contacts when one of the groups is invisible

I faced with problem while fetching phone numbers for linked contacts on HTC phone.
The problem only with contacts that have phone numbers in invisible group.
E.g. I have contact in addressbook that linked from Google and Facebook accounts.
Contact1 - Google account (contact name, email)
Contact1 - Facebook account (contact name, phone number)
In the Contacts settings Google group is active and Facebook group is hidden.
Here what I am doing in the code.
Preparing cursor for ListView that shows only contacts with phone numbers and in visible group.
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.LOOKUP_KEY
};
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
CursorLoader cursorLoader = new CursorLoader(AllContactsNewActivity.this,
uri, projection, ContactsContract.Contacts.HAS_PHONE_NUMBER +" = 1 " +
" AND " + ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '1'",
selectionArgs, sortOrder);
The Contact1 is presented in the list.
When user click on this contact I am fetching phone numbers from selected contact, but get empty list.
CursorLoader cursorLoader = new CursorLoader(
AllContactsNewActivity.this,
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?",
new String[] { String.valueOf(contactId) }, null);
I have already tried to use RAW_CONTACT_ID, _ID, LOOKUP_KEY for fetching numbers but w/o luck.
Could some one give me piece of advice how I can fetch phone numbers for these contacts or just not show such contacts in the ListView.

I had this exact same problem and searched for hours to find a solution. This is probably too late for you, but if you use the following code the facebook contacts are not included in the listing.
Please note that this uses deprecated code. I suspect, however, that we are stuck using it until facebook gets their act together and stops violating every rule Google ever made regarding contacts.
Calling code:
Intent intent = new Intent(Intent.ACTION_PICK, Contacts.Phones.CONTENT_URI);
startActivityForResult(intent, SELECT_CONTACT);
Later in onActivityResult
Uri contactData = data.getData();
Cursor c = managedQuery(contactData, null, null, null, null);
startManagingCursor(c);
if (c.moveToFirst()) {
String name = c.getString(c.getColumnIndexOrThrow(People.NAME));
String number = c.getString(c.getColumnIndexOrThrow(People.NUMBER));
Toast.makeText(this, name + " has number " + number, Toast.LENGTH_LONG).show();
}

Android Contacs

I'm able to fetch all the contacts from Contact list in android(phone numbers and emails)
but fetching all of them takes long time.
To speed up this I have stored them once in my application. But now i can't get the updated contacts. How does they need to be synced with my application?
Problem arises when I try to display them in a list because a user database of phone numbers and emails exceeds the 2000. I'm currently using base adapter implementation for this.
Can somebody help me out for large contact database?
Application like GroupMe n Viber show all user contacts very fast can somebody tell me brief explanation to achieve it.
String KEY_NAME = "Name";
String KEY_NO = "No";
String selection = ContactsContract.CommonDataKinds.Phone.IN_VISIBLE_GROUP + " = 1";
String sortOrder = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
String data="";
String name="";
ContactEntry contactObj;
String id;
String index="";
final String[] projection = new String[]{ContactsContract.Contacts._ID , ContactsContract.Contacts.DISPLAY_NAME , ContactsContract.Contacts.HAS_PHONE_NUMBER};
final String[] email_projection = new String[] {ContactsContract.CommonDataKinds.Email.DATA , ContactsContract.CommonDataKinds.Email.TYPE};
final String[] phone_projection = new String[] {ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.TYPE};
ContentResolver cr = context.getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI , projection , selection , null , sortOrder);
if(cur.getCount()>0){
while(cur.moveToNext()){
id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
// get the phone number
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI , phone_projection ,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",new String[]{id}, null);
while (pCur.moveToNext()){
data = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
if(!temp.contains(data) && !data.equals(null)){
//Adding PhoneNumbers in List
}
}
pCur.close();
}
Cursor emailCur = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, email_projection,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", new String[]{id}, null);
while (emailCur.moveToNext()){
data = emailCur.getString(emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
if(!temp.contains(data) && !data.equals(null)){
//Adding Email in List
}
}
emailCur.close();
}
}
I have used the above code
How can i pass the Curser in CurosrAdaper for all Emails and Phonenumbers.
please help me i havn't found any solution.

Android provides a sync adapter to solve this problem. you may refer to this example for the implementation.
http://developer.android.com/resources/samples/SampleSyncAdapter/index.html

i had same issue , i have used ResourceCursorAdapter which fetches contacts as fast as Contact API from android....

I think you need to have a service (or) Asynch task something like that which periodically updates contacts from phone to your local app. Otherwise you can't synch.
