# Daily Client SDK for Android

> Build real-time video and audio calling into your native Android applications.

The Daily Client SDK for Android is a native Kotlin/Java library built on WebRTC. It handles media negotiation, network traversal, and participant management so you can focus on building your UI.

## Hello, world

Add the SDK to your `build.gradle`, then join a call:

```groovy theme={null}
dependencies {
    implementation 'co.daily:client:latest.release'
}
```

```kotlin theme={null}
import co.daily.CallClient
import co.daily.CallClientListener
import co.daily.model.Participant

val call = CallClient(applicationContext)
val videoViews = mutableMapOf<String, VideoView>()

call.addListener(object : CallClientListener {
    override fun onParticipantJoined(participant: Participant) {
        val videoView = VideoView(applicationContext)
        videoViews[participant.id] = videoView
        addVideoViewToMyUI(view = videoView)
        videoView.track = participant.media?.camera?.track
    }

    override fun onParticipantUpdated(participant: Participant) {
        videoViews[participant.id]?.track = participant.media?.camera?.track
    }
})

call.join(url = "https://your-domain.daily.co/room-name") {
    it.error?.apply { Log.e(TAG, "Error joining: $msg") }
    it.success?.apply { Log.i(TAG, "Joined successfully") }
}

// Turn off camera
call.setInputsEnabled(camera = false)

// Leave and release when done
call.leave { }
call.release()
```

## API structure

The SDK is organized around the tasks involved in building a call. For each task you get methods to **update** state, methods to **get** current state, and **events** via `CallClientListener` to react to changes.
