getting contact name using phone number not working

I am using below code for getting incoming call number which works fine.
String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
In next step, I tried to get contatc name using method getContactName(mContext,number):
public static String getContactName(Context context, String phoneNumber) {
ContentResolver cr = context.getContentResolver();
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Cursor cursor = cr.query(uri, new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME}, null, null, null);
if (cursor == null) {
return null;
}
String contactName = null;
if(cursor.moveToFirst()) {
contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
}
if(cursor != null && !cursor.isClosed()) {
cursor.close();
}
return contactName;
}
but the method always return null (my incoming call is one of my contacts and its number and number string are exactly the same. I don't know that why this code does not work. I really appreciate any help you can provide.

Try adding the permission in Manifest:
<uses-permission android:name="android.permission.READ_CONTACTS"/>

Android Get contact name from phone number

I am trying to get details about contact using phone number everything works perfect, but when the contact number is saved with some special characters then i unable to get the contact details below is my code:
//function called
getContactName("+11234567890");
and the same number saved in contact as (+1(123)456-789)
//function
public String getContactName(String number) {
String name;
if(number != null && !number.equals("")){
// define the columns I want the query to return
String[] projection = new String[] {
ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.PhoneLookup._ID};
// encode the phone number and build the filter URI
Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
// query time
Cursor cursor = _context.getContentResolver().query(contactUri, projection, null, null, null);
if(cursor != null) {
if (cursor.moveToFirst()) {
name = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
}
cursor.close();
}
}
return name;
}

Use the bellow function to get the name from phone number. I have tested it recently. It works fine. because phone lookup will replace all special character from phone number.
ex- I saved new number 0+0141(12-23) with name Gaurav. And I call the function getContactName(01411223) then it will returns the name Gauav.
Please use following function and let me know if it does not work.
public static String getContactName(Context context, String phoneNumber) {
ContentResolver cr = context.getContentResolver();
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Cursor cursor = cr.query(uri, new String[]{PhoneLookup.DISPLAY_NAME}, null, null, null);
if (cursor == null) {
return null;
}
String contactName = null;
if(cursor.moveToFirst()) {
contactName = cursor.getString(cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME));
}
if(cursor != null && !cursor.isClosed()) {
cursor.close();
}
return contactName;
}

You can delete all non digit chars from the string with replaceAll("\\D+","");, have a look and let me know if it works!
public String getContactName(String number) {
number = number.replaceAll("\\D+","");
String name;
if(number != null && !number.equals("")){
// define the columns I want the query to return
String[] projection = new String[] {
ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.PhoneLookup._ID};
// encode the phone number and build the filter URI
Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
// query time
Cursor cursor = _context.getContentResolver().query(contactUri, projection, null, null, null);
if(cursor != null) {
if (cursor.moveToFirst()) {
name = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
}
cursor.close();
}
}
return name;
}

may be this code will helps
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));
}
}

How to convert a phone number to that contacts name in TextView on Android?

We would like to automatically replace phone numbers within text (TextView) with their corresponding contact names.
Is there a library or code snippet that already does this? Else my naive approach would be to:
get phone numbers in the text (via a regex, maybe the one used for autolink phone)
query for contact that has this number (for each number found)
if found, replace with the corresponding name of the contact
(suggestion for query from #Skynet)
This is currently beeing discussed in a feature request for TextSecure but could be useful for other android apps as well.

You don't need to take the list of all contacts. You can get contact name from a phone number. Use this method:
public static String getContactName(Context context, String phoneNumber) {
ContentResolver contentResolver = context.getContentResolver();
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Cursor cursor = contentResolver.query(uri, new String[]{ PhoneLookup.DISPLAY_NAME }, null, null, null);
if (cursor == null) {
return null;
}
String contactName = null;
if(cursor.moveToFirst()) {
contactName = cursor.getString(cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME));
}
if(cursor != null && !cursor.isClosed()) {
cursor.close();
}
return contactName;
}
Good luck.

Try this method to get the contact name using a phone number:
public String getContactName(String number) {
Uri uri = Uri.withAppendedPath(
ContactsContract.PhoneLookup.CONTENT_FILTER_URI,
Uri.encode(number));
Cursor cur = context.getContentResolver().query(
uri,
new String[] { ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.PhoneLookup.NUMBER,
ContactsContract.PhoneLookup._ID }, null, null, null);
String contactName = "";
if (cur.moveToNext()) {
int name = cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
contactName = cur.getString(name);
}
cur.close();
return contactName;
}
Use this when replacing numbers to contact names in your TextView. I hope it works. :)

android search contact after phone number

I have the following 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();
}
}
Toast.makeText(this, name, Toast.LENGTH_LONG).show();
return name;
}
Here I am searching a contact name based on the full contact phone nummber. Is it possible to search contacs based just on 4 numbers from the phone number?

Get the entire contacts numbers and names, use regex to get entries that match?

Android: Retrieve contact name from phone number

I would like to retrieve the name of a contact associated with an incoming telephone number. As I process the incoming number in the broascastreceiver having a String with the name of the incoming caller would help my project greatly.
I would think this involves a query using the sql WHERE clause as a filter, but do I need to sort the contacts? An example or hint would be of great assistance.

Although this has already been answered, but here is the complete function to get the contact name from number. Hope it will help others:
public static String getContactName(Context context, String phoneNumber) {
ContentResolver cr = context.getContentResolver();
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Cursor cursor = cr.query(uri, new String[]{PhoneLookup.DISPLAY_NAME}, null, null, null);
if (cursor == null) {
return null;
}
String contactName = null;
if(cursor.moveToFirst()) {
contactName = cursor.getString(cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME));
}
if(cursor != null && !cursor.isClosed()) {
cursor.close();
}
return contactName;
}
[Updating based on Marcus's comment]
You will have to ask for this permission:
<uses-permission android:name="android.permission.READ_CONTACTS"/>

For that you need to use the optimized PhoneLookup provider as described.
Add the permission to AndroidManifest.xml:
<uses-permission android:name="android.permission.READ_CONTACTS"/>
Then:
public String getContactName(final String phoneNumber, Context context)
{
Uri uri=Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI,Uri.encode(phoneNumber));
String[] projection = new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME};
String contactName="";
Cursor cursor=context.getContentResolver().query(uri,projection,null,null,null);
if (cursor != null) {
if(cursor.moveToFirst()) {
contactName=cursor.getString(0);
}
cursor.close();
}
return contactName;
}

This was very helpful, here's my final code for retrieving the caller's Name, id, and Photo:
private void uploadContactPhoto(Context context, String number) {
Log.v("ffnet", "Started uploadcontactphoto...");
String name = null;
String contactId = null;
InputStream input = null;
// define the columns I want the query to return
String[] projection = new String[] {
ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.PhoneLookup._ID};
// encode the phone number and build the filter URI
Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
// query time
Cursor cursor = context.getContentResolver().query(contactUri, projection, null, null, null);
if (cursor.moveToFirst()) {
// Get values from contacts database:
contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup._ID));
name = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
// Get photo of contactId as input stream:
Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long.parseLong(contactId));
input = ContactsContract.Contacts.openContactPhotoInputStream(context.getContentResolver(), uri);
Log.v("ffnet", "Started uploadcontactphoto: Contact Found # " + number);
Log.v("ffnet", "Started uploadcontactphoto: Contact name = " + name);
Log.v("ffnet", "Started uploadcontactphoto: Contact id = " + contactId);
} else {
Log.v("ffnet", "Started uploadcontactphoto: Contact Not Found # " + number);
return; // contact not found
}
// Only continue if we found a valid contact photo:
if (input == null) {
Log.v("ffnet", "Started uploadcontactphoto: No photo found, id = " + contactId + " name = " + name);
return; // no photo
} else {
this.type = contactId;
Log.v("ffnet", "Started uploadcontactphoto: Photo found, id = " + contactId + " name = " + name);
}
... then just do whatever you want with "input" (their photo as an InputStream), "name", and "contactId".
And here are the docs listing the ~15 or so columns you have access to, just add them to the projection near the start of the code up above:
http://developer.android.com/reference/android/provider/ContactsContract.PhoneLookup.html

This version is the same as Vikram.exe's answer with code to avoid the ANR
interface GetContactNameListener {
void contactName(String name);
}
public void getContactName(final String phoneNumber,final GetContactNameListener listener) {
new Thread(new Runnable() {
#Override
public void run() {
ContentResolver cr = getContentResolver();
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Cursor cursor = cr.query(uri, new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME}, null, null, null);
if (cursor == null) {
return;
}
String contactName = null;
if(cursor.moveToFirst()) {
contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
}
if(cursor != null && !cursor.isClosed()) {
cursor.close();
}
listener.contactName(contactName);
}
}).start();
}

Pass the contact number from which you are getting the call in the following method. This Method will check whether the contact is saved in your mobile or not. If the contact is saved then it will return the contact name otherwise it return a string unknown number
Add this code in your Broadcast receiver class
public String getContactDisplayNameByNumber(String number,Context context) {
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
name = "Incoming call from";
ContentResolver contentResolver = context.getContentResolver();
Cursor contactLookup = contentResolver.query(uri, null, null, null, null);
try {
if (contactLookup != null && contactLookup.getCount() > 0) {
contactLookup.moveToNext();
name = contactLookup.getString(contactLookup.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
// this.id =
// contactLookup.getString(contactLookup.getColumnIndex(ContactsContract.Data.CONTACT_ID));
// String contactId =
// contactLookup.getString(contactLookup.getColumnIndex(BaseColumns._ID));
}else{
name = "Unknown number";
}
} finally {
if (contactLookup != null) {
contactLookup.close();
}
}
return name;
}

For that, we can use the PhoneLookup provider to get the names or contact details using the mobile number.
Add the permission to AndroidManifest.xml:
<uses-permission android:name="android.permission.READ_CONTACTS"/>
Add the following custom kotlin method in your activity and call the same with the required mobile number.
fun getContactNameByPhoneNumber(context: Context, phoneNumber: String): String? {
var phone = phoneNumber
if(phoneNumber != null && phoneNumber.length > 0 && phoneNumber[0].equals('+'))
phone = phoneNumber.substring(3)
val projection = arrayOf(
ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER
)
val cursor = context.contentResolver.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection,
ContactsContract.CommonDataKinds.Phone.NUMBER, null, null
) ?: return ""
for (i in 0 until cursor.count) {
cursor.moveToPosition(i)
val nameFieldColumnIndex = cursor
.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME)
val phoneFieldColumnIndex = cursor
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)
if(phone.equals(cursor.getString(phoneFieldColumnIndex)))
return cursor.getString(nameFieldColumnIndex)
}
return "Unknown"
}
