Horologist provides what it is called the "Media Toolkit": a set of libraries to build media apps on Wear OS and a sample app that you can run to see the toolkit in action.
The following modules in the Horologist project are part of the toolkit:
- media-ui: common media UI components and screens like
- media: domain model for media related functionality. Provides an abstraction to the UI
media-ui) that is agnostic to the
- media-data: implementation of the domain module (
media) using Media3.
Playeron top of Media3 including functionalities such as avoiding playing music on the watch speaker.
- media-sample: sample app to listen to downloaded music.
The Media Toolkit libraries are separated by layers (UI, domain and data) following the recommended app architecture .
For example, if your project already contains an implementation for the player and you are only interested in using the media screens provided by the toolkit, then only the UI library needs to be added as a dependency. Thus, no extra dependencies ( e.g. Media3) will be added to your project.
On the other hand, if your project does not need any of the media screens or media UI components provided by the UI library, and you are only interested in the player implementation, then only the data library needs to be added as a dependency to your project.
The usage of the toolkit will vary according to the requirements of your project.
As per architecture overview, your project might not need to add all the libraries of the toolkit as dependency. If that’s the case, refer to the documentation of each library required to your project for a guide on how to get started.
For a walkthrough on how to build a very simple media application using some libraries of the toolkit, refer to this guide.
For good reference on how to use all the libraries available in the toolkit, refer to the code of the media-sample app.
