ExoPlayer

ExoPlayer is an application level media player for Android. It provides an alternative to Android’s MediaPlayer API for playing audio and video both locally and over the Internet. ExoPlayer supports features not currently supported by Android’s MediaPlayer API, including DASH and SmoothStreaming adaptive playbacks. Unlike the MediaPlayer API, ExoPlayer is easy to customize and extend, and can be updated through Play Store application updates.

Documentation

The developer guide provides a wealth of information to help you get started.
The class reference documents the ExoPlayer library classes.
The release notes document the major changes in each release.

Using ExoPlayer

ExoPlayer modules can be obtained via jCenter. It's also possible to clone the repository and depend on the modules locally.

Via jCenter

The easiest way to get started using ExoPlayer is to add it as a gradle dependency. You need to make sure you have the jcenter repository included in the build.gradle file in the root of your project:

repositories {
    jcenter()
}

Next add a gradle compile dependency to the build.gradle file of your app module. The following will add a dependency to the full ExoPlayer library:

compile 'com.google.android.exoplayer:exoplayer:r2.X.X'

where r2.X.X is your preferred version. Alternatively, you can depend on only the library modules that you actually need. For example the following will add dependencies on the Core, DASH and UI library modules, as might be required for an app that plays DASH content:

compile 'com.google.android.exoplayer:exoplayer-core:r2.X.X'
compile 'com.google.android.exoplayer:exoplayer-dash:r2.X.X'
compile 'com.google.android.exoplayer:exoplayer-ui:r2.X.X'

The available modules are listed below. Adding a dependency to the full ExoPlayer library is equivalent to adding dependencies on all of the modules individually.

exoplayer-core: Core functionality (required).
exoplayer-dash: Support for DASH content.
exoplayer-hls: Support for HLS content.
exoplayer-smoothstreaming: Support for SmoothStreaming content.
exoplayer-ui: UI components and resources for use with ExoPlayer.

For more details, see the project on Bintray. For information about the latest versions, see the Release notes.

Locally

Cloning the repository and depending on the modules locally is required when using some ExoPlayer extension modules. It's also a suitable approach if you want to make local changes to ExoPlayer, or if you want to use a development branch.

First, clone the repository into a local directory and checkout the desired branch:

git clone https://github.com/google/ExoPlayer.git
git checkout release-v2

Next, add the following to your project's settings.gradle file, replacing path/to/exoplayer with the path to your local copy:

gradle.ext.exoplayerRoot = 'path/to/exoplayer'
gradle.ext.exoplayerModulePrefix = 'exoplayer-'
apply from: new File(gradle.ext.exoplayerRoot, 'core_settings.gradle')

You should now see the ExoPlayer modules appear as part of your project. You can depend on them as you would on any other local module, for example:

compile project(':exoplayer-library-core')
compile project(':exoplayer-library-dash')
compile project(':exoplayer-library-ui)

Developing ExoPlayer

Project branches

The project has dev-vX and release-vX branches, where X is the major version number.
Most development work happens on the dev-vX branch with the highest major version number. Pull requests should normally be made to this branch.
Bug fixes may be submitted to older dev-vX branches. When doing this, the same (or an equivalent) fix should also be submitted to all subsequent dev-vX branches.
A release-vX branch holds the most recent stable release for major version X.

Using Android Studio

To develop ExoPlayer using Android Studio, simply open the ExoPlayer project in the root directory of the repository.
