How To Get Contact List In Android Programmatically

The previous article tells you how to add android contacts for each detailed contact field programmatically. This article will show you how to read contacts fields out from android contacts and print them in the android monitor Logcat console.

1. How To Query Android Contacts.

  1. To get all the android contacts fields, we need to use the android contacts content provider as following to get the Cursor object.
    ContentResolver contentResolver = getContentResolver();
    
    Cursor cursor = contentResolver.query(ContactsContract.Data.CONTENT_URI, queryColumnArr, whereClauseBuf.toString(), null, null);
  2. But before you loop the cursor object to get detailed contact field values, you need the below code to verify that the cursor is not null and the cursor return columns.
    if(cursor!=null && cursor.getCount() > 0)
    {
             ....................
    }
  3. Otherwise below code maybe throw cursor index out of bounds exception error.
    cursor.getLong(cursor.getColumnIndex(ContactsContract.Data.CONTACT_ID));
  4. Below is the error message text.
    android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0.
  5. The error is because although the cursor object is not null, it does not contain any columns of data.

2. Query Android Contacts Example.

  1. There is an android contact in the emulator, it is generated by our previous article. When you click the “LOAD ALL CONTACTS” button, it will display all the contact fields on the android studio Logcat console.

3. Get Android Contacts Programmatically Example Source Code.

  1. Read contacts need runtime permission, so you need to add the below permissions in the AndroidManifest.xml file. You can read Android Marshmallow Runtime Permission Example to learn more about android runtime permission.
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <uses-permission android:name="android.permission.WRITE_CONTACTS" />
  2. Below is the main activity java file ContactsOperationActivity.java.

  1. Below is DataDTO file source code.

    package com.dev2qa.example.datasharing.contacts.dto;

    /**
    * Created by Jerry on 1/26/2018.
    */

    public class DataDTO {

    private int dataType;

    private String dataValue;

    public int getDataType() {
    return dataType;
    }

    public void setDataType(int dataType) {
    this.dataType = dataType;
    }

    public String getDataValue() {
    return dataValue;
    }

    public void setDataValue(String dataValue) {
    this.dataValue = dataValue;
    }
    }

    I think i found why.
    I made a change to the code at the where clause.
    Instead of whereClauseBuf.append(ContactsContract.Data.RAW_CONTACT_ID);
    i put this whereClauseBuf.append(ContactsContract.Data.CONTACT_ID);.
    and of course i first retrieve the contact ids and not the raw contact ids.

    I tried the code only on my phone. I dont know if it will work fine on another device.

  3. Dimitrios Vassilakis

    It works for some contacts. For some contacts failed to fetch info because cursor.getCount() is zero.
    I cannot understand why. The contact has phone numbers, email e.t.c.

  4. Someone Somewhere

    String photo = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Photo.PHOTO));

    causes exception:
    android.database.sqlite.SQLiteException: unknown error (code 0): Unable to convert BLOB to string

    Pro-Tip: to store a binary as a String you have to convert it to base64 😉

    1. The example code work.

      But the getAllContacts() method just print added or exist contacts info in the logcat console.

      You had better add below code to require WRITE_CONTACTS permission before add contacts.

      else if(!hasPhoneContactsPermission(Manifest.permission.WRITE_CONTACTS))
      {
      requestPermission(Manifest.permission.WRITE_CONTACTS);
      }

      First add contacts then load and print them in logcat console.
