Contacts name are coming null while cursor has all contacts - android

I'm getting 'name = null' in this code, while cursor has all my contacts in it, i tried many different ways but it all does the same thing.
String[] contact_names, mobile_numbers;
Cursor cursor = getActivity().getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,null, null, null);
while (cursor.moveToFirst()) {
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
contact_names[contact_names.length] = name;
Cursor phones = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?" + contactId, null, null);
while (phones.moveToNext()) {
String number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
mobile_numbers[mobile_numbers.length] = number;
}
phones.close();
}
cursor.close();

You don't need to query multiple times, use the following to get it all in one query,
String[] PROJECTION_MAIN = new String[]{
ContactsContract.Contacts._ID,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.Contacts.DISPLAY_NAME
};
Cursor cursor = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
PROJECTION_MAIN, null, null, null);
while (cursor.moveToNext()) {
String contact_id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String phone = cleanNumber(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)), context);
}

How to get phone numbers of contact members of a given contact group in android using cursor

I have gotten the group id from cursor. Let's say groupID as '59'. I want to get all contacts from the groups where Group_ID is 59. I have manipulated projection, selection and cursor with different classes of ContactsContract but no use. Here is what my code for getting member contacts looks like.
Uri uri = ContactsContract.Data.CONTENT_URI;
String[] projection22 = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Data.CONTACT_ID,
ContactsContract.Data.DISPLAY_NAME
};
String selection = null;
String[] selectionArgs = null;
if(groupID != null && !"".equals(groupID)) {
selection = ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID
+ " = ?";
selectionArgs = new String[] { groupID };
}
String sortOrder = null;
Cursor cursor = getContentResolver().query(uri, projection22,
selection, selectionArgs, sortOrder);
Now the cursor returns zero count. Please get me through to use the cursor in a proper way.
public void getSampleContactList(int groupID) {
contactList = new ArrayList<ConatctData>();
Uri groupURI = ContactsContract.Data.CONTENT_URI;
String[] projection = new String[] {
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.GroupMembership.CONTACT_ID };
Cursor c = getContentResolver().query(
groupURI,
projection,
ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID
+ "=" + groupID, null, null);
while (c.moveToNext()) {
String id = c
.getString(c
.getColumnIndex(ContactsContract.CommonDataKinds.GroupMembership.CONTACT_ID));
Cursor pCur = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[] { id }, null);
while (pCur.moveToNext()) {
ConatctData data = new ConatctData();
data.name = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
data.phone = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contactList.add(data);
}
pCur.close();
}
}
class ConatctData {
String phone, name;
}

how to fetch local phone contacts effeciently

I am using the below code to fetch the local phone contacts. It is working fine and also fetching the contacts very fast.
But the problem comes here, in my contact list there are few contacts that are having multiple Emails and multiple phone numbers.
In case of multiple phone or emails address it repeats the name of the same person multiple times.
And if i change
ContactsContract.CommonDataKinds.Email.CONTENT_URI
to ContactsContract.CommonDataKinds.Phone.CONTENT_URI then it will repeat name according to the number of phone number exists for a contact. Please help
private static final String[] PROJECTION = new String[]{
ContactsContract.CommonDataKinds.Email.CONTACT_ID,
ContactsContract.CommonDataKinds.Nickname.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Email.DATA,
ContactsContract.CommonDataKinds.Phone.NUMBER,
};
ContentResolver cr = mContext.getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, PROJECTION, null, null, null);
if (cursor != null) {
try {
final int contactIdIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.CONTACT_ID);
final int displayNameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int emailIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
final int phoneIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
long contactId;
String displayName, email, phone, photo;
while (cursor.moveToNext()) {
mNK_UserModel = new NK_Contact();
contactId = cursor.getLong(contactIdIndex);
displayName = cursor.getString(displayNameIndex);
//Adding display name
mNK_UserModel.setFirstName(displayName);
Util.DEBUG_LOG(1, "contact", "contact id :" + contactId);
al_PhoneContacts.add(mNK_UserModel);
}
} finally {
cursor.close();
}
}
If i had to guess i would say you are missing a "break" in your while-loop. Since the cursor tries to fetch the next available column entry. But have a look at my solution which worked for me in the past.
It uses a seperate cursor for each row which gives you more control over the data.
Map<String, String> contactDataMap = new HashMap<String, String>();
Uri contactData = data.getData();
Cursor cursor = getContentResolver().query(contactData, null, null, null, null);
cursor.moveToFirst();
String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
String id = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
contactDataMap.put(NAME, (name != null)?name:"");
if (Integer.parseInt(cursor.getString(
cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{id},
null);
while (pCur.moveToNext()) {
String number = pCur.getString(pCur.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));
contactDataMap.put(PHONE, (number != null)?number:"");
break;
}
pCur.close();
}
Cursor emailCur = getContentResolver().query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
while (emailCur.moveToNext()) {
String email = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
contactDataMap.put(MAIL, (email != null)?email:"");
break;
}
emailCur.close();
cursor.close();

efficient way to load contacts with name and phone and picture with only one query

I have the following code to load all contacts with their phones and pictures on samsung s3 device.
public static void getAllContactWithNumberAndNameAndPhoto(Context context,
ArrayList<ContactInfo> mContactList, boolean starred) {
ContentResolver cr = context.getContentResolver();
Cursor cur = null;
if (starred == true) {
cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
"starred=?", new String[] { "1" }, null);
} else {
cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null,
null, null);
}
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
ContactInfo item = new ContactInfo();
String id = cur.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
// Uri photo = PhoneUtils.getPhotoUriFromID(context, id);
String starredValue = cur.getString(cur
.getColumnIndex(ContactsContract.Contacts.STARRED));
boolean isFav = false;
if (starredValue.equals("1"))
isFav = true;
if (Integer
.parseInt(cur.getString(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);
while (pCur.moveToNext()) {
String phoneNo = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
item.addPhone(removeCharactersFromPhoneNumber(phoneNo));
}
pCur.close();
// if (photo != null) {
//
// item.setPhoto(photo.toString());
// }
item.setName(name);
item.setFavorite(isFav);
item.setRecent(false);
mContactList.add(item);
}
}
cur.close();
}
}
when I run this code on 1000 contacts it takes about 40 second to load
when I remove the part of loading multiple phones for the same 1000 contact, it takes about 1.5 second.
Can any one tell me if there is an efficient way to load contacts phone and not let the user to wait all this time.
Try this:
private Cursor getContacts() {
// Run query
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME, ContactsContract.Contacts.PHOTO_URI, ContactsContract.Contacts.PHOTO_THUMBNAIL_URI, ContactsContract.CommonDataKinds.Phone.CONTENT_URI }; // put the items u need here
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '"
+ ("1") + "'";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
return getContentResolver().query(uri, projection, selection, selectionArgs,
sortOrder);
}

Android save LocalContacts into Database

Here is how local contacts are saved into database 1 by 1. This method lasts for about 20-30 sec. The while works really slow
public StringBuilder getLocalContacts(Context context, List<Contact> contactList) {
StringBuilder sb = new StringBuilder();
Cursor cursor = context.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null,
null);
// this while works slow
while (cursor.moveToNext()) {
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (Integer.valueOf(hasPhone) == 1) {
String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
// You know it has a number so now query it like this
Cursor phones = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null);
while (phones.moveToNext()) {
Contact contact = new Contact();
contact.setFullName(contactName);
contact.setAddressBookId(contactId);
String phoneNumber = phones.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contact.setPhone(phoneNumber);
sb.append(phoneNumber).append("|");
Cursor emails = context.getContentResolver().query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null);
while (emails.moveToNext()) {
// This would allow you get several email addresses
String emailAddress = emails.getString(emails
.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
contact.setEmail(emailAddress);
break;
}
emails.close();
contactList.add(contact);
}
phones.close();
}
}
cursor.close();
return sb;
}
Does anyone have any idea what would make this method do the job in about 1 sec? or is there any faster method?

Get distinct email id from contact list

I have a contact list with multiple names having the same email Ids.How can I modify the below code so that I get only names with distinct email id.
public ArrayList<String> getNameEmailDetails(){
ArrayList<String> names = new ArrayList<String>();
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
Cursor cur1 = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
while (cur1.moveToNext()) {
//to get the contact names
String name=cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
Log.e("Name :", name);
String email = cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
Log.e("Email", email);
if(email!=null){
names.add(name);
}
}
cur1.close();
}
}
return names;
}
there is a cursor in sqlite to get the distinct values, the useage of true gives the distinct values only
Cursor cursor = sqliteDB.query(true,"window",new String[]{"MediaType","_id",TAG_DATA_OR_LOCATION}, null, null,"DataOrLocation", null, null, null);
public Cursor query (boolean distinct, String table, String[] columns, String selection, String[] selectionArgs, String groupBy, String having, String orderBy, String limit)
