Android SDK Samples

The Android SDK comes with many ready-to-use samples under the webrtc_android_sample_app module. These samples demonstrate different use cases and scenarios for WebRTC streaming.

  • The webrtc_android_sample_app module has three packages:

1. Minimal

  • Contains the simplest PublishActivity, a minimal WebRTC publish sample.

2. Basic

  • Includes multiple samples: publish activity, play activity, screen capture activity, conference activity, data channel only activity, peer activity, and settings.

3. Advanced

  • Provides samples for more complex use cases: conference activity with speaker indicator, MP3 publish activity, MP4 publish activity, MP4 publish with surface activity, multi-track play activity, publish activity with “Are You Speaking”, and USB camera activity.
