Getting email and phone from contacts Android

I'm attempting to retrieve both email and phone via a single cursor described below. I'm using the Email.CONTENT_URI, hence I don't retrieve the phone number, so my phoneColumn is returning email. I tried using Phone.CONTENT_URI but it only returns a smaller subset of contacts (possibly because it only fetches ones that have phone numbers). Is there a way to get both email and phone with a specific Uri or how can I do it with two cursors?
Cursor cursor = context.getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI,
projection, null, null, order);
int idColumn = cursor.getColumnIndex(ContactsContract.Data._ID);
int nameColumn = cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME);
int emailColumn = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
int phoneColumn = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA);
where projection is:
String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Data.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Email.DATA,
ContactsContract.CommonDataKinds.Phone.DATA, }

Please have a look here. You should find all the necessary examples for such kind of querying.
For an example, you can fetch all information of a contactId in this way:
Cursor data = context.getContentResolver().query(
Data.CONTENT_URI, new String[] { Data._ID,Data.MIMETYPE,
Email.ADDRESS, Photo.PHOTO},Data.CONTACT_ID
+ "=?" + " AND " + "(" + Data.MIMETYPE + "='"
+ Photo.CONTENT_ITEM_TYPE + "' OR " + Data.MIMETYPE
+ "='" + Email.CONTENT_ITEM_TYPE +"')",
new String[] {String.valueOf(contactId)}, null);
You can fetch info for all contacts in this way and then probably sort it according to your criteria. You can build queries like this based on your need.

I have created this library to solve all your queries. It will only save contacts with at least one email or phone number. Also it will remove duplicates from emails and phone numbers from same contacts (created by 3rd party apps like whatsapp).
Please have a look at it.

How can I get certain mobile numbers from contact list?

I have an app that has to show my phone contact list. But how can I get some mobile numbers (that I want)?

For your example 6XXXXXXX type of number, here is a query to get that type of numbers only.
ContentResolver cr = getContentResolver();
Cursor contacts = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
ContactsContract.Contacts.DISPLAY_NAME + " LIKE '"
+ " 6 " + "%' ", null, "UPPER("
+ ContactsContract.Contacts.DISPLAY_NAME + ") ASC");
Hope it will help you.

Working for me :
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
while (phones.moveToNext())
{
String Number=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
Add a permisson to app manifest file :
<uses-permission android:name="android.permission.READ_CONTACTS"/>

Retrieving contact info in Android fails with exception

ALL,
I am trying to execute following piece of code:
ContentResolver cr = getContentResolver();
Cursor cur = cr.query( ContactContract.Contacts.CONTENT_URI, null, "ContactsContract.Contacts.DISPLAY_NAME LIKE '" + name + "'", null, null );
However when running this code, I am getting SQLite exception: "Don't know such file ContactsContract.Contacts.DISPLAY_NAME:, while compiling "....."".
The problem is that I don't know in advance what will "name" contain, hence using "LIKE" clause.
Is there a better way to perform such operation? Or I am just doing it incorrectly?
Thank you in advance for any help.

Or I am just doing it incorrectly?
ContactsContract.Contacts.DISPLAY_NAME is a Java construct. Use:
Cursor cur = cr.query( ContactContract.Contacts.CONTENT_URI, null, ContactsContract.Contacts.DISPLAY_NAME + " LIKE '" + name + "'", null, null );
Or, use positional parameters:
Cursor cur = cr.query( ContactContract.Contacts.CONTENT_URI, null, ContactsContract.Contacts.DISPLAY_NAME + " LIKE ?", args, null );
where args is a one-element string array containing your name.

Loading phone contacts in ascending order

I am trying to load phone contacts and tried to show the contact names in ascending order. My code is given below:
Cursor cursor = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, null,
ContactsContract.Contacts.HAS_PHONE_NUMBER + " = 1", null,
ContactsContract.Contacts.DISPLAY_NAME + " ASC");
I got the required output. But a problem is there, names staring with small letter is shown as last one. First the capital letters are sorted, only after that contact names staring with small letters is shown. PLS HELP
OUTPUT IS:
Alfin A
Bipin B
Calvin C
Jobin
Shine
anurag U
shine H

Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null,
ContactsContract.Contacts.HAS_PHONE_NUMBER + " = 1",
null,
"UPPER(" + ContactsContract.Contacts.DISPLAY_NAME + ") ASC");

How to filter the results of content resolver in android?

I would like to get user contacts and then append some kind of regular expression and append them to a list view. I am currently able to get all the contacts via
getContentResolver().query(People.CONTENT_URI, null, null, null, null);
and then pass them to a custom class that extends SimpleCursorAdapter.
So I would like to know how to get only the contacts that match a regular expression and not all of users contacts.

Instead of
getContentResolver().query(People.CONTENT_URI, null, null, null, null);
you should use something like
final ContentResolver resolver = getContentResolver();
final String[] projection = { People._ID, People.NAME, People.NUMBER };
final String sa1 = "%A%"; // contains an "A"
cursor = resolver.query(People.CONTENT_URI, projection, People.NAME + " LIKE ?",
new String[] { sa1 }, null);
this uses a parameterized request (using ?) and provides the actual values as a different argument, this avoids concatenation and prevents SQL injection mainly if you are requesting the filter from the user. For example if you are using
cursor = resolver.query(People.CONTENT_URI, projection,
People.NAME + " = '" + name + "'",
new String[] { sa1 }, null);
imagine if
name = "Donald Duck' OR name = 'Mickey Mouse") // notice the " and '
and you are concatenating the strings.

You can query the content provider with sql type input, the Query method is just a wrapper for an sql command.
Here is an example where I query for a Contacts name given a particular number
String [] requestedColumns = {
Contacts.Phones.NAME,
Contacts.Phones.TYPE
};
Cursor contacts = context.getContentResolver().query(
Contacts.Phones.CONTENT_URI,
requestedColumns,
Contacts.Phones.NUMBER + "='" + phoneNumber + "'",
null, null);
Note that instead of null I have parameters that build up the sql statement.
The requestColumns are the data I want to get back and Contacts.Phones.NUMBER + "='" + phoneNumber + "'" is the Where clause, so I retrieve the Name and Type where the Phone Number matches

You should be able to put a legal SQLite WHERE clause as the third argument to the query() method, including a LIKE, but there's no native REGEXP function in SQLite and Android doesn't seem to let you define your own. So depending how complex your needs are, a set of other SQLite conditions and LIKE expressions might do the trick.
See the documentation on the query method under ContentResolver and SQLite expressions.

Actually REGEXP with Calllog Content Provider works (means that regexp() function is defined for that content provider's Database https://sqlite.org/lang_expr.html#regexp)! But it is very slow: ~15 sec across ~1750 records.
String regexp = "([\\s\\S]{0,}" +
TextUtils.join("||[\\s\\S]{0,}", numbers) +
")";
cursor = context.getContentResolver().query(
CallLog.Calls.CONTENT_URI,
null,
CallLog.Calls.NUMBER + " REGEXP ?",
new String[]{regexp},
CallLog.Calls.DATE + " DESC"
);
