# Android SDK Overview

> Build Android applications with Pipecat's Kotlin client library

The Pipecat Android SDK provides a Kotlin implementation for building voice and multimodal AI applications on Android. It handles:

* Real-time audio and video streaming
* Bot communication and state management
* Media device handling
* Event handling

## Installation

Add the dependency for your chosen transport to your `build.gradle` file. For example, to use the Daily transport:

```gradle theme={null}
implementation "ai.pipecat:daily-transport:1.0.3"
```

## Example

Here's a simple example using Daily as the transport layer.

```kotlin theme={null}
val callbacks = object : PipecatEventCallbacks() {

    override fun onBackendError(message: String) {
        Log.e(TAG, "Error from backend: $message")
    }

    // ...
}

val options = PipecatClientOptions(callbacks = callbacks)

val client: PipecatClientDaily = PipecatClient(DailyTransport(context), options)

// Kotlin coroutines:
client.startBotAndConnect(startBotParams).await()

// Or, callbacks:
client.startBotAndConnect(startBotParams).withCallback {
    // ...
}
```
