Beta Release Information

Spotify just unlocked a new feature in its mobile apps for Android and iOS—the ability to control the music playing in the desktop application from a mobile phone or tablet, assuming you're.

We’re releasing this SDK early to gain feedback from the developer community about the future of our Android SDKs. Please file feedback about missing issues or bugs over at our issue tracker, making sure you search for existing issues and adding your voice to those rather than duplicating.

The Spotify App Remote SDK

The Spotify App Remote SDK allows your application to interact with the Spotify app running in thebackground as a service. The capabilities of this SDK include getting metadata for the currentlyplaying track and context, issuing basic playback commands and initiating playback of tracks.

The Spotify App Remote SDK is a set of lightweight objects that connect with the Spotify app and let you control it while all the heavy lifting of playback is offloaded to the Spotify app itself. The Spotify app takes care of playback, networking, offline caching and OS music integration, leaving you to focus on your user experience. Also, with the Spotify App Remote SDK, moving from your app to the Spotify app and vice versa is a streamlined experience where playback and metadata always stay in sync.

#### Key Features

• Lightweight library < 300k. No native code or processor architecture dependencies
• Playback always in sync with Spotify app
• Processing of playback and caching as well as network traffic is accounted for by the Spotify app
• Handles system integration such as audio focus, lockscreen controls and incoming calls
• Automatically handles track relinking for different regions
• Works offline and online and does not require Web API calls to get metadata for PlayerState

Note: While certain playback controls work offline and playback can happen offline for offlined content, apps cannot connect and start communicating with Spotify unless there is an internet connection

Getting started

• Download the library from the app-remote-lib directory
• Follow the Beginner’s Tutorial. The tutorial is designed to help you set up your build environment and get started with the Spotify App Remote SDK (Android). It leads you through the creation of a simple app that connects to the Spotify app, plays a playlist and subscribes to PlayerState.
• Have a look at the demo app in the demo directory. The demo app includes full source code and example uses of the APIs available in the Spotify App Remote SDK (Android) to help you get started.

SDK Components Overview

The download package includes comprehensive Javadoc documentation of all API classes in the docsfolder.

Models

Some of the models in the Spotify App Remote SDK are

• Album
• Artist
• Track
• PlayerState
• PlayerContext

The PlayerState

It could answer the following questions

• what track is being played now?
• is the player playing/paused?
• what is current playback position?
• is the track saved to the user’s library?

The PlayerContext

Get metadata like the title of the current context that is playing - such as an album or a playlist.

SpotifyAppRemote

Think of it as an interface to the Spotify app thatlets you control some aspects of the app, query for the data, and subscribe to the events.It exposes set of API like PlayerApi and ImagesApi.You should use it as en entry point to all your interactions with the Spotify app.

Connector

Is a component that lets you receive an instance of SpotifyAppRemote.

PlayerApi

Send playback related commands such as:

• play content by URI
• resume/pause playback
• shuffle playback

You can also subscribe to the following events:

• PlayerState updates
• PlayerContext updates

Note: A Spotify Premium account is required to play a single track uri. You should make a call to the UserApi to get the on-demand capabilities of a user before attempting to play a single track uri.

Spotify Download For Android

UserApi

Get user-related data and perform actions such as:

• user capabilities - can this user play music on demand?
• add/remove content in a user’s library

ImagesApi

Use it to download cover arts by URI

ContentApi

Get a list of content

ConnectApi

Control on what device the Spotify app should be playing music

Authentication, Authorization and Scopes

In order to use the Spotify App Remote SDK, your application will need to get user’s permission to control playbackremotely first. This can be done in two ways:

1. By using Single Sign-On library. To do that you’ll need to include theAndroid Authentication Library in your project and request app-remote-control scope. This approach is useful if you need to request more scopes or an access token for other purposes, for example to communicate with Spotify Web API. Our Android SDK Authentication Guide provides instructions and examples for both methods.
2. Use built-in authorization mechanism in Spotify App Remote (Android). To do that you’ll need to request to showauthorization view when connecting to Spotify. The library will automatically request theapp-remote-control scope and show the auth view if user hasn’t agreed to it yet. Currently youwon’t be able to get the token back from the Remote SDK. It’s also not possible to requestadditional scopes. The Beginner’s Tutorial contains an example onhow to use this method.

Note: The Spotify Android app must be installed on the user’s device in order for the Spotify App Remote SDK to work. Please see the “Installing Spotify” section of the Content Linking guide on how to direct users to download Spotify.
