How to customize the UI of the demo session_automotive app? #1883

Closed feroxtransmissons closed 1 week ago

feroxtransmissons commented 1 week ago

It seems that the automotive demo session app does not contain an activity or any layout files to define the UI of the app, instead possibly using some default layout? The layout .xml files in lib-ui do not reflect what the app looks like so it is unclear how this layout is defined. Can somehow tell me how I would go about customizing the UI for this demo automotive app?

Thanks very much.

A media app only provides a service that the Autom,otive app connects with a MediaBrowser against. The UI of an Automotive app is provided by the client. You can't customize this.

The documentation around building media apps gives you an idea how the architecture works: https://developer.android.com/training/cars/media/automotive-os

You can start the emulator in Android Studio with an Automotive emulator image to test the Automotive demo app or your own version: https://developer.android.com/training/cars/testing/emulator

Thanks. We build our own Trout image we test on. I am curious then how does Amazon Music, Tidal and Apple Music downloaded from the automotive play store have custom UI's that differ?

Yeah, don't know. You need to get that from the Automotive docs or talk to the Automotive team. We maintain the Media3 library that offers session integration. The Automotive media center connects, browses the library and plays media by using the API we provide through the session.

I'm not familiar with whether an app can integrate with Automotive OS in different ways I'm afraid.

Got it. Do you know if I could at least add the Seekbar to this app? I am able to follow the logic in DemoMediaLibrarySessionCallback.kt for adding custom command buttons like Shuffle and Fast Forward, or even custom buttons, but is the Seekbar possible at all? Thank you.
