ExoPlayer Demo (AndroidX Media3)

Kotlin sample that plays adaptive HLS video with AndroidX Media3 ExoPlayer.

This project uses Media3 1.11.0 (androidx.media3:media3-exoplayer, media3-exoplayer-hls, and media3-ui), verified on Google Maven and the Media3 release notes (stable as of 5 August 2026).

What the demo does

• Plays an official Media3 demo HLS stream (Apple BIPBOP fMP4, including subtitle renditions) via ExoPlayer.setMediaItem.
• Uses androidx.media3.ui.PlayerView with rewind / fast-forward (15s seek increments on the player), buffering indicator, and the subtitle button.
• Restores playback position, play-when-ready, speed, and mute across lifecycle events.
• Picture-in-picture on API 26+: Home / PiP button uses PictureInPictureParams. Playback continues in PiP; overlay controls hide.
• Overlay controls for playback speed (0.5x–2.0x) and mute / unmute.

The HLS URI is taken from the Media3 main demo media list:

Requirements

• JDK 17 (Android Gradle Plugin 8.11)
• Android Studio Ladybug / Narwhal or newer (or command-line SDK)
• Android SDK with compileSdk / targetSdk 35
• Device or emulator on API 24+ with network access

Build and run

From this directory:

./gradlew :app:assembleDebug

Install on a connected device:

./gradlew :app:installDebug

Or open the project in Android Studio, wait for Gradle sync, and run the app configuration.

The app needs the INTERNET permission (already declared) so ExoPlayer can fetch the HLS playlist and segments.
