Welcome to your friendly guide to Android Contacts, Reborn, a powerful library designed to simplify contact management on Android devices. Open-sourced in October 2021, this library empowers developers with an extensive range of APIs for handling contact data without the hassle associated with the Contacts Provider.

Getting Started

Before diving into the nitty-gritty details, you need to set up the library. Don’t worry; it’s as easy as pie!

• Step 1: Include JitPack in your project’s repositories list.
• Step 2: Add the dependency for the core module to your build file.

Here’s how your Gradle file might look:

repositories {
    maven { url 'https://jitpack.io' }
}
dependencies {
    implementation 'com.github.vestrel00:contacts-android:0.3.2'
}

Quick Start with Queries

Let’s visualize how to manage contacts with some quick queries. Imagine you’re a librarian looking for books in a vast library. Instead of combing through every aisle for each title, you can ask the librarian (our library API) to fetch the information for you. Likewise, the Contacts, Reborn library lets you perform queries efficiently.

Here’s a simple Kotlin snippet to fetch all contacts:

val contacts = Contacts(context).query().find()

And if you want to search for contacts based on specific criteria, it can be done like this:

val contacts = Contacts(context)
    .broadQuery()
    .wherePartiallyMatches(searchText)
    .find()

Advanced Queries

Let’s say you want to apply several filters while fetching contacts. This is like being able to request a special type of book from a librarian: “I need science fiction books by J.K. Rowling, published after 2001, with over 400 pages.” You can construct such a complex query as shown below:

val contacts = Contacts(context)
    .query()
    .where(Name.GivenName startsWith "leo")
    .and(Email.Address endsWith("gmail.com"))
    .find()

Inserting, Updating, and Deleting Contacts

You’re not just limited to querying; you can also insert, update, or delete contacts with ease!

• To Insert a Contact:

  
  val insertResult = Contacts(context)
      .insert()
      .rawContacts(NewRawContact().apply {
          name = NewName().apply {
              givenName = "John"
              familyName = "Doe"
          }
          emails.add(NewEmail().apply {
              address = "john.doe@example.com"
              type = EmailEntity.Type.WORK
          })
      })
      .commit()
  

• To Update a Contact:

  
  Contacts(context)
      .update()
      .contacts(johnDoe.mutableCopy {
          setOrganization {
              company = "Microsoft"
          }
      })
      .commit()
  

• To Delete a Contact:

  
  Contacts(context)
      .delete()
      .contacts(johnDoe)
      .commit()
  

Troubleshooting Tips

If you run into issues or if things don’t work as expected, consider the following:

• Ensure you have the necessary permissions granted.
• Make sure the JitPack repository URL is correctly included.
• Check if you are using the correct version of the library.
