# Text tracks on Android

The articles in this section describe how to implement common use-cases related to text tracks, subtitles, closed captions and metadata. These use-cases can range from programmatically detecting new metadata, to side-loading subtitles.

THEOplayer supports

* subtitle and closed caption formats like WebVTT, CEA-608, DVB Subs and TTML;
* metadata formats like ID3, emsg, EventStream and `EXT-X-DATERANGE`.

The TextTrack API allows you to programmatically switch between text tracks, detect events related to text tracks (e.g. a new active cue) and more.
