The current code flags a lint error: ``` Error: Call requires API level 24 (current min is 16): java.lang.Iterable#forEach [NewApi] ``` I think this is a bit confusing because this is calling the Java [`Iterable.forEach`](https://developer.android.com/reference/java/lang/Iterable#forEach(java.util.function.Consumer%3C?%20super%20T%3E)) method which was added in Java 8 (and therefore is only available on API 24 and up), but there is **also** a Kotlin [`List.forEach`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/for-each.html) method which is available in all versions of Kotlin (and therefore all Android versions). Since this is a Kotlin file, at first glance you would assume this is the Kotlin method - but it's not. This also doesn't seem to be flagged by Android Studio, but is caught by Gradle lint on the command line. #minor-release PiperOrigin-RevId: 529112610
AndroidX Media
AndroidX Media is a collection of libraries for implementing media use cases on Android, including local playback (via ExoPlayer) and media sessions.
Documentation
- The developer guide provides a wealth of information.
- The class reference documents the classes and methods.
- The release notes document the major changes in each release.

Migration for existing ExoPlayer and MediaSession projects
You'll find a migration guide for existing ExoPlayer and MediaSession users on developer.android.com.
API stability
AndroidX Media releases provide API stability guarantees, ensuring that the API surface remains backwards compatible for the most commonly used APIs. APIs intended for more advanced use cases are marked as unstable. To use an unstable method or class without lint warnings, you’ll need to add the OptIn annotation before using it. For more information see the UnstableApi documentation.
Using the libraries
You can get the libraries from the Google Maven repository. It's also possible to clone this GitHub repository and depend on the modules locally.
From the Google Maven repository
1. Add module dependencies
The easiest way to get started using AndroidX Media is to add gradle
dependencies on the libraries you need in the build.gradle file of your app
module.
For example, to depend on ExoPlayer with DASH playback support and UI components you can add dependencies on the modules like this:
implementation 'androidx.media3:media3-exoplayer:1.X.X'
implementation 'androidx.media3:media3-exoplayer-dash:1.X.X'
implementation 'androidx.media3:media3-ui:1.X.X'
where 1.X.X is your preferred version. All modules must be the same version.
Please see the AndroidX Media3 developer.android.com page for more information, including a full list of library modules.
This repository includes some modules that depend on external libraries that need to be built manually, and are not available from the Maven repository. Please see the individual READMEs under the libraries directory for more details.
2. Turn on Java 8 support
If not enabled already, you also need to turn on Java 8 support in all
build.gradle files depending on AndroidX Media, by adding the following to the
android section:
compileOptions {
targetCompatibility JavaVersion.VERSION_1_8
}
3. Enable multidex
If your Gradle minSdkVersion is 20 or lower, you should
enable multidex in order
to prevent build errors.
Locally
Cloning the repository and depending on the modules locally is required when
using some libraries. It's also a suitable approach if you want to make local
changes, or if you want to use the main branch.
First, clone the repository into a local directory:
git clone https://github.com/androidx/media.git
cd media
Next, add the following to your project's settings.gradle file, replacing
path/to/media with the path to your local copy:
gradle.ext.androidxMediaModulePrefix = 'media-'
apply from: file("path/to/media/core_settings.gradle")
You should now see the AndroidX Media modules appear as part of your project. You can depend on them as you would on any other local module, for example:
implementation project(':media-lib-exoplayer')
implementation project(':media-lib-exoplayer-dash')
implementation project(':media-lib-ui')
Developing AndroidX Media
Project branches
Development work happens on the main branch. Pull requests should normally be
made to this branch.
The release branch holds the most recent stable release.
Using Android Studio
To develop AndroidX Media using Android Studio, simply open the project in the root directory of this repository.
