Hi I am trying to get a contacts first name. I know how to get a contacts full name, but I cannot figure out how obtain just the name. any ideas?
Uri lookupUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
String[] mPhoneNumberProjection = { PhoneLookup._ID, PhoneLookup.NUMBER, PhoneLookup.DISPLAY_NAME };
Cursor cur = context.getContentResolver().query(lookupUri,mPhoneNumberProjection, null, null, null);
try {
if (cur.moveToFirst()) {
String name = cur.getString(2);
// do something with the name
}
} finally {
cur.close();
}
I haven't personally tried this, but you may have to do a further RawContacts.CONTENT_URI query against the PersonLookup.LOOKUP_KEY from the first query, allowing you to retrieve the StructuredName.GIVEN_NAME field.

So I've written a query to extract the WhatsApp contacts of a phone. My initial query goes like this:
Cursor c = con.getContentResolver().query(
ContactsContract.RawContacts.CONTENT_URI,
new String[]{ContactsContract.RawContacts.CONTACT_ID, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY},
ContactsContract.RawContacts.ACCOUNT_TYPE + "= ?",
new String[]{"com.whatsapp"},
null
);
ArrayList<String> myWhatsappContacts = new ArrayList<String>();
int contactNameColumn = c.getColumnIndex(ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY);
while (c.moveToNext()) {
// You can also read RawContacts.CONTACT_ID to read the
// ContactsContract.Contacts table or any of the other related ones.
myWhatsappContacts.add(c.getString(contactNameColumn));
}
The purpose of this is to find out how many WhatsApp contacts the phone has at any one time. When I do:
Log.i("WhatsApp contacts found:", Integer.toString(myWhatsappContacts.size());
It should print out how many WhatsApp contacts there were into LogCat. And this works - up to a point.
Let's say for example that the number of WhatsApp contacts I have now is 101. The next phase of this little project is to delete away ALL contacts if there are more than 100 of them. In which case, we go:
if (myWhatsappContacts.size() > 100) {
//Delete all contacts code here
}
I've tested the delete contacts code, it works. I check the contacts directory of the phone via the contacts app, and it says 0. But now when I do the query again (refer to code above), it still shows 101! What's going on?
If it helps, my DeleteContacts method is as follows:
private void deleteContact(Context ctx, String phone, String name) {
Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phone));
Cursor cur = ctx.getContentResolver().query(contactUri, null, null, null, null);
try {
if (cur.moveToFirst()) {
do {
if (cur.getString(cur.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME)).equalsIgnoreCase(name)) {
String lookupKey = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, lookupKey);
ctx.getContentResolver().delete(uri, null, null);
return;
}
} while (cur.moveToNext());
}
} catch (Exception e) {
System.out.println(e.getStackTrace());
} finally {
cur.close();
}
return;
}
What am I doing wrong? Is my DeleteContacts code faulty? Or is the query itself faulty?
I'm getting all phone's SMS with this URI - Telephony.Sms.Inbox.CONTENT_URI
TextBasedSmsColumns contains all columns for a projection.
Cursor is built like this:
cursor = getContentResolver().query(Telephony.Sms.Inbox.CONTENT_URI,
new String[] { BaseColumns._ID, TextBasedSmsColumns.ADDRESS },
null, null, null);
There is a TextBasedSmsColumns.ADDRESS column that contains a phone number OR a contact name. So how can I always get the phone number for the SMS? Should I use another approach to get all SMS?
This is how I got.
Uri uriSMSURI = Uri.parse("content://sms/inbox");
Cursor cur = getContentResolver().query(uriSMSURI, null, null, null, null);
if (cur != null) {
while (cur.moveToNext()) {
String body = cur.getString(cur.getColumnIndexOrThrow("body"));
//Here you will get all PhoneNumbers
String phoneNumber = cur.getString(cur.getColumnIndexOrThrow("address"));
}
cur.close();
}
I'm trying to find a contact by display name. The goal is to open this contact and add more data to it (specifically more phone numbers), but I'm struggling to even find the contact I want to update.
This is the code I'm using:
public static String findContact(Context context) {
ContentResolver contentResolver = context.getContentResolver();
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI;
String[] projection = new String[] { PhoneLookup._ID };
String selection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " = ?";
String[] selectionArguments = { "John Johnson" };
Cursor cursor = contentResolver.query(uri, projection, selection, selectionArguments, null);
if (cursor != null) {
while (cursor.moveToNext()) {
return cursor.getString(0);
}
}
return "John Johnson not found";
}
I do have a contact called "John Johnson", but the method always returns "not found". I also tried searching for a contact with just one name, so that makes no difference.
I suspect that it's something wrong with the uri, selection or selection arguments, because I couldn't find any example online of searching for contacts with a given display name, and it seems display name is a special kind of information, different from for example a phone number.
Any ideas how I can achieve to find John Johnson?
UPDATE: I found out how to find a contact by display name:
ContentResolver contentResolver = context.getContentResolver();
Uri uri = Data.CONTENT_URI;
String[] projection = new String[] { PhoneLookup._ID };
String selection = StructuredName.DISPLAY_NAME + " = ?";
String[] selectionArguments = { "John Johnson" };
Cursor cursor = contentResolver.query(uri, projection, selection, selectionArguments, null);
if (cursor != null) {
while (cursor.moveToNext()) {
return cursor.getString(0);
}
}
return "John Johnson not found";
This code returns the contact id of the first contact with display name "John Johnson". In my original code I had the wrong uri and the wrong selection in my query.
I thinks the issue may caused by the projection you set. Projection is used to tell android which column of data you want to query then you only give the id column so the display name won't return. Try to remove the projection to see whether it works.
-- Cursor cursor = contentResolver.query(uri, projection, selection, selectionArguments, null);
++ Cursor cursor = contentResolver.query(uri, null, selection, selectionArguments, null);
Change Your Query URI.
You are using a URI that is meant to filter only phones numbers:
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI;
You need to use a URI that has access to the display_name column, like this:
Uri uri = ContactsContract.Data.CONTENT_URI;
There's a decent breakdown of what URIs to use and when to use them on the Android SDK Documentation:
If you need to read an individual contact, consider using CONTENT_LOOKUP_URI instead of CONTENT_URI.
If you need to look up a contact by the phone number, use PhoneLookup.CONTENT_FILTER_URI, which is optimized for this purpose.
If you need to look up a contact by partial name, e.g. to produce filter-as-you-type suggestions, use the CONTENT_FILTER_URI URI.
If you need to look up a contact by some data element like email address, nickname, etc, use a query against the ContactsContract.Data table. The result will contain contact ID, name etc.
//method for gaining id
//this method get a name and make fetch it's id and then send the id to other method //named "showinformation" and that method print information of that contact
public void id_return(String name) {
String id_name=null;
Uri resultUri = ContactsContract.Contacts.CONTENT_URI;
Cursor cont = getContentResolver().query(resultUri, null, null, null, null);
String whereName = ContactsContract.Data.MIMETYPE + " = ? AND " + ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME + " = ?" ;
String[] whereNameParams = new String[] { ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE,name};
Cursor nameCur = getContentResolver().query(ContactsContract.Data.CONTENT_URI, null, whereName, whereNameParams, ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME);
while (nameCur.moveToNext()) {
id_name = nameCur.getString(nameCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.CONTACT_ID));}
nameCur.close();
cont.close();
nameCur.close();
//for calling of following method
showinformation(id_name);
}
//method for showing information like name ,phone, email and other thing you want
public void showinformation(String id) {
String name=null;
String phone=null;
String email=null;
Uri resultUri = ContactsContract.Contacts.CONTENT_URI;
Cursor cont = getContentResolver().query(resultUri, null, null, null, null);
String whereName = ContactsContract.Data.MIMETYPE + " = ? AND " + ContactsContract.CommonDataKinds.StructuredName.CONTACT_ID+ " = ?" ;
String[] whereNameParams1 = new String[] { ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE,id};
Cursor nameCur1 = getContentResolver().query(ContactsContract.Data.CONTENT_URI, null, whereName, whereNameParams1, ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME);
while (nameCur1.moveToNext()) {
name = nameCur1.getString(nameCur1.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME));}

nameCur2.close();
cont.close();
nameCur2.close();
String[] whereNameParams3 = new String[] { ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,id};
Cursor nameCur3 = getContentResolver().query(ContactsContract.Data.CONTENT_URI, null, whereName, whereNameParams3, ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME);
while (nameCur3.moveToNext()) {
email = nameCur3.getString(nameCur3.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));}
nameCur3.close();

The below code should do the trick
if (displayName != null) {
Uri lookupUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_FILTER_URI, Uri.encode(displayName));
String[] displayNameProjection = { ContactsContract.Contacts._ID, ContactsContract.Contacts.LOOKUP_KEY, Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ? ContactsContract.Contacts.DISPLAY_NAME_PRIMARY : ContactsContract.Contacts.DISPLAY_NAME };
Cursor cur = context.getContentResolver().query(lookupUri, displayNameProjection, null, null, null);
try {
if (cur.moveToFirst()) {
return true;
}
} finally {
if (cur != null)
cur.close();
}
return false;
} else {
return false;
}
Reference: Retrieving a List of Contacts Article
I am looking to get the RAW_CONTACT_ID of a specific Contact using PhoneLookup or even just the Contacts LookupKey.
I know the contacts table has a column name_raw_contact_id that references the raw_contacts._id column but it doesn't seem to be returned when querying ContactsContract.Contacts.CONTENT_LOOKUP_URI with the contacts lookup key.
My phone lookup query is:
String[] projection = new String[] {
PhoneLookup.DISPLAY_NAME, PhoneLookup.LOOKUP_KEY };
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
Cursor c = resolver.query(uri, projection, null, null, null);
Then I am looking up the Contact based on the lookup key:
String[] contactProjection = new String[] {
ContactsContract.Contacts.NAME_RAW_CONTACT_ID
};
Uri contactUri = Uri.withAppendedPath(
ContactsContract.Contacts.CONTENT_LOOKUP_URI, lookupKey);
Cursor contactCursor = resolver.query(contactUri,
contactProjection, null, null, null);
However, this doesn't compile and I get
cannot find symbol: variable NAME_RAW_CONTACT_ID
location: class android.provider.ContactsContract.Contacts
But the android documentation shows NAME_RAW_CONTACT_ID as a column.
Is there any way I can get the RAW_CONTACT_ID based off either phone number or lookup key?
I found that the answer is to make a third query:
long rawContactId = -1;
Cursor c = getContentResolver().query(RawContacts.CONTENT_URI,
new String[]{RawContacts._ID},
RawContacts.CONTACT_ID + "=?",
new String[]{String.valueOf(contactId)}, null);
try {
if (c.moveToFirst()) {
rawContactId = c.getLong(0);
}
} finally {
c.close();
}
But it should be noted that there can be multiple RawContact's per one Contact and the above query will get ALL RawContact's associated with the contactId
ContactsContract.Contacts.NAME_RAW_CONTACT_ID column needs API level 21 or greater so make sure your are compiling with this version.
Also you can use ContactsContract.PhoneLookup._ID column in your first query to get the Contact_Id and then use this Contact_Id in your 3rd query so your problem will be solved in 2 queries instead of 3.
private HashSet<Long> getRawContactIdsForContact(long contactId)
{
HashSet<Long> ids = new HashSet<Long>();
Cursor cursor = context.getContentResolver().query(RawContacts.CONTENT_URI,
new String[]{RawContacts._ID},
RawContacts.CONTACT_ID + "=?",
new String[]{String.valueOf(contactId)}, null);
if (cursor != null && cursor.moveToFirst())
{
do
{
ids.add(cursor.getLong(0));
} while (cursor.moveToNext());
cursor.close();
}
return ids;
}
In my app, user writes a phone number, and I want to find the contact name with that phone number?
I usually search the contacts like this:
Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
But I do this to access all contacts... In this app I only want to get the contact name of the given phone number... How can I restrict the query?
Or do I have to go trough all contacts and see if any has the given phone number? But I believe that this can be very slow this way...
If you want the complete code:
public String getContactDisplayNameByNumber(String number) {
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
String name = "?";
ContentResolver contentResolver = getContentResolver();
Cursor contactLookup = contentResolver.query(uri, new String[] {BaseColumns._ID,
ContactsContract.PhoneLookup.DISPLAY_NAME }, null, null, null);
try {
if (contactLookup != null && contactLookup.getCount() > 0) {
contactLookup.moveToNext();
name = contactLookup.getString(contactLookup.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
//String contactId = contactLookup.getString(contactLookup.getColumnIndex(BaseColumns._ID));
}
} finally {
if (contactLookup != null) {
contactLookup.close();
}
}
return name;
}
You should have a look at the recommended ContactsContract.PhoneLookup provider
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.
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
resolver.query(uri, new String[]{PhoneLookup.DISPLAY_NAME,...
