Contact Store

Access to contacts is one of the most frequent use cases in Android applications. Even if your app is not a contact management app, there are various cases where you might need access to the device contacts (such as referring other users to the app).

For developers to access the device contacts, they need to use ContentProviders. This introduces a lot of frustrations and complications. For someone that has never worked with ContentProviders before, the documentation can be tedious to go through. The lack of a type-safe API leads to repeated errors, developer frustration, along with a waste of time and resources for the developer and the team.

Contact Store is a modern contacts Android API written in Kotlin. It utilises Coroutine's Flow to notify the developer for updates happening to the Contacts database.
