Reading contact phone numbers works for some and not others? - android

I am reading contact names and phone numbers from the contacts list in Android. I am reading the names successfully. However, when I go to look up a contact phone number by name (which are all unique in this case, it's just a test), it works perfectly for only one contact, gets no phone number for others, and gets the wrong phone number for one.
Here is the code in my getNumbers method:
private String getNumber(String name){
String returnMe="";
ContentResolver contentResolver = getContentResolver();
Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null,
"DISPLAY_NAME = '" + getIntent().getStringExtra("name") + "'", null, null);
if(cursor.moveToFirst()){
String identifier = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
Cursor phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, ContactsContract.CommonDataKinds.Phone._ID + " = " + identifier, null, null);
while(phones.moveToNext()){
returnMe = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
int type = phones.getInt(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
switch(type){
case ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE:
System.out.println("mobile number found"); break;
default:
System.out.println("nothing found."); break;
}
}
}
return returnMe;
}

You're doing a few things wrong:
1) The second query must target the Data table, not the Phone table:
Cursor phones = contentResolver.query(ContactsContract.Data.CONTENT_URI, ...
and specify that you want the Phone number in the DATA1 column in the where clause:
Data.MIMETYPE = Phone.CONTENT_ITEM_TYPE
2) You need to filter the results by the RawContact's _ID
This compares the _ID of the Contact row with the _ID of the Phone row, which have very little chance to be the same:
ContactsContract.CommonDataKinds.Phone._ID + " = " + identifier
This compares the Data.CONTACT_ID with the cursor's Contact._ID property
Data.CONTACT_ID + " = " + identifier
The example on the Data javadoc page gives a more complete example:
Finding all Data of a given type for a given contact
Cursor c = getContentResolver().query(Data.CONTENT_URI,
new String[] {Data._ID, Phone.NUMBER, Phone.TYPE, Phone.LABEL},
Data.CONTACT_ID + "=?" + " AND "
+ Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE + "'",
new String[] {String.valueOf(contactId)}, null);

See my answer:
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));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
//Query phone here
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()) {
// Get phone numbers here
}
pCur.close();
}
}
}
}

How to receive local contacts with emai addresses using the content resolver

I am developing an Android app and want to receive my local contacts. To be exact I want to display all contacts which have an email address. My current approach looks like this
import android.provider.ContactsContract.CommonDataKinds.Email;
import android.provider.ContactsContract.Contacts;
import android.provider.ContactsContract.Data;
private static final String[] CONTACT_PROJECTION = new String[] {
Email.CONTACT_ID,
Contacts.DISPLAY_NAME_PRIMARY,
Email.ADDRESS,
};
Cursor data = mResolver.query(Data.CONTENT_URI,
CONTACT_PROJECTION,
Data.MIMETYPE + "='" + Email.CONTENT_ITEM_TYPE + "'",
null, Contacts.DISPLAY_NAME_PRIMARY + " ASC");
The problem using this query is, that the result contains rows that doesn't match a contact in my local address book. Probably I used those email addresses before but didn't saved it to my address book.
I have already tried another approach where I made a query on Contacts.CONTENT_URI with Contacts._ID. This id is used as a foreign key to match the contacts in a second query against their emails. The solution was a nested cursor and the runtime was really slow. For a hundred contacts the query took more than two seconds to match. This is a reason for using the async CursorLoader but I want to avoid it if possible.
Any suggestions? Thanks in advance
#Edit 1:
Unfortunately both solutions don't archive the desired improvement.
For example, when I write a new email to a previous unknown address with my gmail app afterwards the address shows up in both querys with an contact id but not in my normal address book. This kind of "contacts" flood my query.
Could it be related to the value of ContactsContract.CommonDataKinds.Email.TYPE?
#Edit 2:
I found an interesting flag Contacts.IN_VISIBLE_GROUP + "=1". It seems to filter the unwanted addresses.
Has somebody any experience with it? I don't want to filter to much.
This is what I am using in my app:
public void readContacts(){
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));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
System.out.println("name : " + name + ", ID : " + id);
// get the phone number
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
String phone = pCur.getString(
pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
System.out.println("phone" + phone);
}
pCur.close();
// get email and type
Cursor emailCur = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);
while (emailCur.moveToNext()) {
// This would allow you get several email addresses
// if the email addresses were stored in an array
String email = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
String emailType = emailCur.getString(
emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE));
System.out.println("Email " + email + " Email Type : " + emailType);
}
emailCur.close();
}
}
}
}
I have attached one of the functions used in my project. Point of intrest would be selection and selection args.
Snippet
selection = ContactsContract.CommonDataKinds.Email.DATA + " != ?";
selectionArgs = new String[]{""};
This says selection is based on email data and it should not be null.
Similarly you can add any of the selection params as per your need.
Entire Function
public Cursor getInitCursorLoader() {
String[] PROJECTION = null;
String selection = null;
String[] selectionArgs = new String[0];
String order = null;
Uri contentURI = null;
switch (mFriendType) {
case EMAIL:
PROJECTION = new String[]{
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts._ID,
ContactsContract.Contacts.PHOTO_ID,
ContactsContract.CommonDataKinds.Email.TIMES_CONTACTED,
ContactsContract.CommonDataKinds.Email.DATA};
selection = ContactsContract.CommonDataKinds.Email.DATA + " != ?";
selectionArgs = new String[]{""};
contentURI = ContactsContract.CommonDataKinds.Email.CONTENT_URI;
order = ContactsContract.CommonDataKinds.Email.TIMES_CONTACTED + " DESC";
break;
case SMS:
PROJECTION = new String[]{
ContactsContract.Contacts._ID,
ContactsContract.Contacts.PHOTO_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.TIMES_CONTACTED,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.TYPE};
selection = ContactsContract.CommonDataKinds.Phone.TYPE + " = ?";
selectionArgs = new String[]{String.valueOf(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE)};
contentURI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
order = ContactsContract.CommonDataKinds.Phone.TIMES_CONTACTED + " DESC";
break;
}
return mContext.getContentResolver().query(contentURI, PROJECTION, selection, selectionArgs, order);
}

Get all phone numbers from contacts

I use the following code to retrieve all phone number from contacts.
Cursor c = context.getContentResolver().query(
Data.CONTENT_URI,
new String[] { Phone.NUMBER },
Data.MIMETYPE + "='" + Phone.CONTENT_ITEM_TYPE
+ "'", null, null);
It works perfectly in my Android phone.
But some users say my app doesn't get all phone numbers from contacts and just part of them. I can't figure out the reason.. why?
This will get the cursor holding base contact data, and will loop through the phone numbers the contact has, can have multiple.
Uri uri = data.getData();
Cursor cursor=ctx.getContentResolver().query(uri, null, null, null, null);
while (cursor.moveToNext()) {
String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (Boolean.parseBoolean(hasPhone)) {
// You know have the number so now query it like this
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,
null, null);
while (phones.moveToNext()) {
String phoneNumber = phones.getString(
phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
}
}

Android Contacts Content URI HAS_PHONE_NUMBER not working as explained in documentation, please guide

I am trying to run the following code.
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));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
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));
Toast.makeText(NativeContentProvider.this, "Name: " + name + ", Phone No: " + phoneNo, Toast.LENGTH_SHORT).show();
}
pCur.close();
}
}
}
}
So basically I query Contacts.URI and then on the basis of returned data if HAS_PHONE_NUMBER >0 , I query Phone.URI.
When I run this on my phone, I see 3 contacts that get displayed, who don't have corresponding entry in PHONE content URI. These 3 contacts have phone number for sure, as I can see those phone numbers when I go to my phone dialer screen.
How this is possible for a contact to have HAS_PHONE_NUMBER > 0 and still not have corresponding row in PHONE Content URI. Is it not weired, and how to get rid of this.
Please let me know.
Thanks.
This small method gets the contacts based on an option string search parameter. It only fetches contacts that include phone numbers.
private Cursor getContactsCursor(String searchPattern){
String selection = ContactsContract.Contacts.DISPLAY_NAME + " LIKE ? and " + ContactsContract.Contacts.HAS_PHONE_NUMBER + " > 0 ";
String queryArguments = "%" + searchPattern + "%";
String[] selectionArgs = new String[] { queryArguments };
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";
return getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, selection, selectionArgs, sortOrder);
}

How to get "Internet Call" Information in Android

I'm working on android application in which I take backup of all contact information and then restore, I retrieve all information of contact,
For example:
Display Name
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null,null, null, null)
String name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));
Phone Number
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);
Similary
But I unable to get "Internet Call" value.
Kindly anyone tell in which class I will get information about Internet Call information.
Dont know if this is the best way, but it worked, I am fairly new new to android.
Uri uri = ContactsContract.Data.CONTENT_URI;
String[] projection = new String[] {
ContactsContract.Data._ID,
ContactsContract.Data.DISPLAY_NAME,
ContactsContract.CommonDataKinds.SipAddress.SIP_ADDRESS,
ContactsContract.CommonDataKinds.SipAddress.TYPE,
};
String selection =
ContactsContract.Data.MIMETYPE+" ='"
+ContactsContract.CommonDataKinds.SipAddress.CONTENT_ITEM_TYPE+"'";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME+ " COLLATE LOCALIZED ASC";
Cursor cursor = managedQuery(uri, projection, selection, selectionArgs, sortOrder);
It seems that the phone number is stored in misc information data and you have search on the mime type.
HTH
g.
i have tested. i am able to get internet call value. try below code.
Uri uri = ContactsContract.Contacts.CONTENT_URI;
ContentResolver cr = getContentResolver();
Cursor cur=cr.query(uri, null, null, null, sortOrder);
if(cur.getCount()>0){
while(cur.moveToNext()){
if(Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)))> 0) {
String internetWhere = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] internetWhereParams = new String[]{id,ContactsContract.CommonDataKinds.SipAddress.CONTENT_ITEM_TYPE};
Cursor internetCur = cr.query(ContactsContract.Data.CONTENT_URI, null, internetWhere, internetWhereParams, null);
if (internetCur.moveToFirst()) {
String internetCall = internetCur.getString(internetCur.getColumnIndex(ContactsContract.CommonDataKinds.SipAddress.SIP_ADDRESS));
Log.e(TAG, "internet Call: " + internetCall);
} internetCur.close();
}
}
} cur.close();

Android; I only have 2 contacts, yet I can obtain 5 from a query, why?

I have setup 2 test contacts in my emulator.
I'm running the following query, it should pick them both out, populate my domain object, and add to a list. The output at the bottom should therefore be 2, but it is 5, why is this? (cursor.getCount() is 5 instead of 2)
I have stepped through each iteration of the while loop and it is retreving the same contact multiple times, but with different values for POSTCODE, such as the phone number
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.Data.CONTENT_URI,
null, null, null, null);
List<MeCercanaContact> contacts = new ArrayList<MeCercanaContact>();
if (cursor.getCount() > 0)
{
while (cursor.moveToNext())
{
MyContact myContact = new MyContact();
String givenName = cursor.getString(cursor.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
String postcode = cursor.getString(cursor.getColumnIndex(
ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));
myContact.setFirstName(givenName);
myContact.setLastName(postcode);
contacts.add(myContact);
}
}
System.out.println(contacts.size());
After API 21 We Write this Query for remove contact duplicacy.
String select = ContactsContract.Data.HAS_PHONE_NUMBER + " != 0 AND " +
ContactsContract.Data.MIMETYPE
+ " = " + ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE + "
AND "+ ContactsContract.Data.RAW_CONTACT_ID + " = " +
ContactsContract.Data.NAME_RAW_CONTACT_ID;
Cursor cursor = mContent.query(ContactsContract.Data.CONTENT_URI, null, select,
null, null);
You are querying ContactsContract.Data, which is a generic container that holds a list of various contact details, such as phone numbers, postal codes etc.. You must filter the results for the rows whose ContactsContract.Data.MIMETYPE column equals StructuredPostal.CONTENT_ITEM_TYPE:
So change the query to:
Cursor cursor = cr.query(ContactsContract.Data.CONTENT_URI,
null, null, ContacsContract.Data.MIMETYPE + "='" +
ContactsContract.StructuredPostal.CONTENT_ITEM_TYPE + "'", null);
See ContactsContract.Data
a contact that is registered to multiple groups will show up multiple times
if you query the Uri CONTENT_URI = ContactsContract.Data.CONTENT_URI
Add this to your SELECTION:
+ ContactsContract.Data.DATA1 + " = 1 " ; //show only contacts in group 1
