Allow skipping an ad group when requested by IMA, even if we aren't currently playing one, to handle cases where no ads in an ad group will load (so IMA requests resuming content but we never managed to start playing an ad). Use the known ad group index (rather than the expected one) when handling ad group load errors. This ensures we skip the right ad group if we notify IMA of playback errors for every ad in the ad group, then IMA notifies that the ad group is empty via a load error. Also make some other miscellaneous small fixes to ads code: - Avoid warning about unexpected ad group indices more than once. - Output a warning if the ad count in an ad group decreases. - Remove unnecessary assertion. - Fix getting the ad duration for ad indices that haven't loaded yet. - Allow setting an ad group state to its current value. - Fix javadoc for setting the ad resume position. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=184831495
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.

Using ExoPlayer
ExoPlayer modules can be obtained from JCenter. It's also possible to clone the repository and depend on the modules locally.
From 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 and Google repositories
included in the build.gradle
file in the root of your project:
repositories {
jcenter()
google()
}
Next add a gradle compile dependency to the build.gradle
file of your app
module. The following will add a dependency to the full library:
compile 'com.google.android.exoplayer:exoplayer:2.X.X'
where 2.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:2.X.X'
compile 'com.google.android.exoplayer:exoplayer-dash:2.X.X'
compile 'com.google.android.exoplayer:exoplayer-ui:2.X.X'
The available library modules are listed below. Adding a dependency to the full library is equivalent to adding dependencies on all of the library 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.
In addition to library modules, ExoPlayer has multiple extension modules that depend on external libraries to provide additional functionality. Some extensions are available from JCenter, whereas others must be built manually. Browse the extensions directory and their individual READMEs for details.
More information on the library and extension modules that are available from JCenter can be found on Bintray.
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
- Development work happens on the
dev-v2
branch. Pull requests should normally be made to this branch. - The
release-v2
branch holds the most recent release.
Using Android Studio
To develop ExoPlayer using Android Studio, simply open the ExoPlayer project in the root directory of the repository.
