Pick Contact | Android Studio | Kotlin

Implement Contact Pick feature in and Android App

To allow the user to pick a contact from the phone's contacts list, we can use contact intent. You will get all information of the contact e.g. Name, Phone Number(s), Address, Thumbnail, Email, etc. You can use get the specific information according to your requirement. To pick a contact we need to READ_CONTACTS permission.

Check for Java

Add permission in AndroidMenifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.blogspot.atifsoftwares.pickcontact">

    <!--Read contact permission-->
    <uses-permission android:name="android.permission.READ_CONTACTS"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
